Description

The invention relates to a method and device for the production of a fire-resistant, transparent, layered element, comprising at least two transparent supporting elements, between which is a protective layer of a cured mixture of an aqueous solution of alkali metal silicate and colloidal silica. It can be used to produce fireproof, transparent, laminated panels. In particular, it can be used for the manufacture of fire-resistant windows and doors.

A known method of manufacturing a transparent heat-resistant element, which includes the following steps: combining alkaline silicate with a hardener; adjusting the amounts of alkaline silicate and hardener so that the molar ratio of silicon dioxide to alkali metal oxides is greater than 4: 1; introducing the obtained fluid composition into the cavity between two transparent supporting elements; subsequently, without drying, allowing the composition, while maintaining the entire initial water content, to harden to form a solid layer of polysilicate without drying (See, for example, international application No. WO-94/04355, B 32 B 17/06, application 05.08. 1993, published 03.03.1994).

However, this method does not solve the technological problems of preparing transparent, self-hardening, aqueous alkali metal silicate compositions with an SiO ₂ content _of more than 20%. To obtain a self-hardening composition with a large (up to 60%) water content, this method involves the use of an additional hardener and other additives. These additives can degrade the performance of a transparent heat shield element such as transparency, refractive index, and susceptibility to ultraviolet radiation.

The closest in technical essence and the achieved result to the proposed invention are a method and installation for the production of heat-resistant, transparent, layered elements, which includes the following steps: mixing in an container an aqueous solution of alkaline polysilicate with colloidal silica dispersed in water, followed by the formation of an intumescent liquid mixture; at least one first irradiation of said intumescent liquid mixture by means of electromagnetic radiation with a frequency of less than 30 GHz; the degassing of said intumescent liquid mixture with extraction of at least a portion of the water in the vapor phase; introducing said intumescent liquid mixture into the cavity between two transparent sheets.

The installation includes the following parts: fasteners designed to support two or more parallel, transparent layers that are spaced from each other so as to form at least one hermetically sealed chamber for liquids; at least one container for an aqueous solution of alkaline polysilicate and colloidal silica dispersed in water; at least one source of electromagnetic radiation capable of irradiating said liquid mixture; circulation means for transferring said liquid mixture from said container to said chamber through said fixing means; degassing means (See, for example, international application No. WO-02/100636 B 32 B 17/10, B 01 F 13/00, decl. 10.06.02, publ. 19.12.02).

However, in the aforementioned method and device, the problems of economy and improving the operational properties of heat-resistant, transparent, layered elements are not completely resolved. The mixture is pre-irradiated with electromagnetic radiation, previously prepared in a container, which is then pumped from this container to fill in the cavity between two transparent sheets. At the same time, it is known that irradiation of continuous flows of matter is more economical and technological.

In addition, for the preparation of intumescent compositions in the known method uses a liquid alkaline polysilicate and a colloidal solution of silica, available on the market. The properties of a silicate solution as well as colloidal silica change over time. It is difficult to obtain a transparent, self-hardening, flowable silicate composition without prior exposure. The reproducibility of the operational properties of the heat-resistant, transparent, layered element will be negligible.

In addition, there is a high risk of destruction of the pre-assembled stratified element if low pressure is created in the cavity between the bearing elements.

The main objective of the present invention is to provide a technologically advanced and economical method and device for the production of a fire-resistant, transparent, layered element of the required sizes and spatial forms with a protective layer that contains silica more than 20% by weight; has a density of more than 1300 kg / m ³ and a transparency of more than 85% of cheap and commercially available materials.

In addition, the object of the invention is an economical and technological method for the production of a fire-resistant, transparent, layered element, which eliminates the risk of destruction of the bearing elements at the stage of filling the cavities.

These tasks are achieved by the fact that in the method of manufacturing a fire-resistant, transparent, layered element, comprising connecting at least two transparent supporting elements arranged separately against each other and capable of forming at least one hermetically sealed intermediate cavity, preparation transparent, fluid mixture of an aqueous solution of alkali metal silicate and colloidal silica, irradiation with electromagnetic radiation with a frequency of up to 30 GHz, degassing and selection of part of the water in the steam phase, filling the intermediate cavity with the mixture, polymerizing the mixture inside the intermediate cavity according to the invention, preparing a transparent, flowing, self-hardening mixture includes uniform preliminary irradiation of the aqueous solution of an alkali metal silicate and colloidal silica with electromagnetic radiation, mixing of the flows while irradiating, degassing and taking part of the water into vapor phase from the mixture flow with simultaneous irradiation with power from up to 4.5 kW.

It is acceptable that in the method according to the invention the prepared mixture would contain silica more than 20% by weight and have a density of more than 1300 kg / m ³ .

It is also possible that in the method according to the invention would ensure the coordination of the electromagnetic radiation power in the range from 0.6 kW to 4.5 kW with the flow rates of the initial components of the mixture and the mixture itself up to 5 · 10 ^-5 m ³ / s and a vacuum value of up to 3 kPa, created for degassing and partial selection of water in the vapor phase.

It is also possible that in the method according to the invention would ensure the frequency of electromagnetic radiation is consistent with the flow rates of the initial components of the mixture and the mixture itself up to 5 · 10 ^-5 m ³ / s and a vacuum value of up to 3 kPa, created for degassing and partial selection of water in the vapor phase .

It is also possible that in the method according to the invention, the flows of the initial components of the mixture and the flow of the mixture itself would be subjected to ultrasound with a frequency of up to 1 MHz and a power of up to 2 kW.

It is also conceivable that in the method according to the invention, when the intermediate cavity is filled with a mixture, the connected transparent supporting elements are subjected to heat and ultrasound.

These tasks are also achieved by the fact that in a device for implementing a method of manufacturing fire-resistant, transparent, layered elements, comprising a low-pressure chamber, equipped with means capable of supporting connected transparent supporting elements, a chamber for preparing the mixture, having at least one source of electromagnetic radiation , a system for the degassing and extraction of part of the water in the vapor phase, a pumping system, according to the invention, the chamber for preparing the mixture is equipped with a container for preparing a transparent a fluid, self-hardening mixture having three conjugated segments, providing uniform preliminary irradiation of the flows of the initial components of the mixture in the first segment, mixing the flows with simultaneous irradiation in the second segment and taking part of the water in the vapor phase from the mixture flow while irradiating in the third segment, degassing system and the selection of part of the water in the vapor phase is connected to a container for preparing the mixture, two containers for the initial components of the mixture and a low-pressure chamber, the pumping system for It is connected to containers for the initial components of the mixture, a container for preparing the mixture, and means for supporting the connected transparent supporting elements.

It is advisable that in the device according to the invention, the systems for degassing and partial water extraction in the vapor phase and pumping would be equipped with controlling means and regulation means.

It is also advisable that the device according to the invention would be further equipped with an ultrasound source with a frequency of up to 1 MHz and a power of up to 2 kW to sound the streams of the initial components of the mixture and the stream of the mixture itself.

It is also advisable that the device according to the invention would be further provided with means for heating and sounding the low-pressure chamber.

For the production of a fire-resistant, transparent, layered element, a solution of silicate and colloidal silica is prepared, the properties of which change over time. It is difficult to obtain a transparent, self-hardening, flowable silicate composition without first irradiating its starting components. Without such irradiation, the reproducibility of the operational properties of the heat-resistant, transparent, layered element will be negligible.

The operational properties of the mixture and the flame retardant element as a whole are determined by the concentration of silica. A mixture containing silica of more than 20% by weight and having a density of more than 1300 kg / m ³ , as a result of polymerization, turns into a sufficiently hard gel, which provides fire resistance and load-bearing ability of a fire-resistant, transparent layered element.

The required properties of the prepared mixture and the protective layer obtained from it are ensured by matching the power and frequency of electromagnetic radiation with the flow rates of the initial components of the mixture and the mixture itself up to 5 · 10 ^-5 m ³ / s on container segments and a vacuum value of up to 3 kPa created for degassing and partial withdrawal of water in the vapor phase.

The minimum, technologically justified value of the lower limit of the interval of power of electromagnetic radiation is 0.6 kW.

The streams of the initial components of the mixture and the stream of the mixture itself are subjected to ultrasonic treatment with a frequency of up to 1 MHz and a power of up to 2 kW in order to regulate mixing and degassing.

Ultrasonic treatment of the flows of the initial components of the mixture and the flow of the mixture itself during its preparation is preferable at frequencies from 0.2 MHz to 1 MHz and power up to 0.5 kW. At the same time, scoring of the connected load-bearing elements during filling of the cavities is preferable at frequencies from 20 kHz to 50 kHz and power up to 2 kW.

A device for implementing the method includes containers for the starting components, a container for preparing the mixture. The degassing and partial water withdrawal system and the pumping system include control and regulatory means that provide a predetermined vacuum in the containers for the initial components, the container and the low-pressure chamber and expenses within the required limits.

The heating means are designed to heat the connected load-bearing elements for the purpose of preliminary degassing and to avoid temperature shock at the stage of filling the intermediate cavity with the prepared mixture.

In addition, the supporting elements of the supporting elements provide the same pressure in the intermediate cavity of the supporting elements and outside it. As a result, the risk of destruction of the supporting elements during filling of the named cavity with the said mixture under low pressure conditions is eliminated.

Further, the features and advantages of the invention will be more apparent from the detailed description of the preferred, but not exclusive, embodiment of the method and installation for the manufacture of a fire-resistant, transparent, layered element.
