The additive of this invention is characterized in that a mixture of closed cellular plastic particles, disintegrated foamed urea formaldehyde resin and chopped fiberglass filaments or strands form part of the additive. The method for manufacturing the additive of this invention is characterized in that the components forming part of the additive are fed into an air-conveying conduit in mutual mixing relationship to form a uniform mixture during transfer to a silo.
Description
i ~ELLULAR PLASTIC ADDITIVE
This invention relates to a cellular plastic addi-tive to be mixed with a hardening or air-drying compo-nent, preferably consisting of a liquid paint, the addi-tive of the invention imparting to the paint a textured surface when applied on a support.
Ready mixed texturing paints and compositions are previously known and are available on the market. Gener-ally, these compositions consist of ready mixed thickfiller or putty type paint compounds. Special tools, such as rollers with a patterned surface, or toothed spatulas have to be used for the application of such compounds. Often the compound is applied to the support by using a specific spray method. The textured surface coating obtained by using these compounds consists of a thick and very hard coating with a weight up to 8 kg/m2.
The heavy weight of the coating requires a rigid support of high bearing capacity, and additionally the removal of such a compound is time-consuming and expensive. It is often necessary to grind off at least the surface layer to provide a smooth surface. This grinding opera-tion will cause a heavy production of dust. The time of storing these compounds is limited, and the use thereof is restricted to indoor use. Available texture compounds most often are white, but when large amounts are ordered, other colours can be obtained as well.
The additive of this invention can be used not only as a texturing additive but also with e.g. a water sol-uble two-component adhesive. Then, the additive may be used as a filler or a repairing compound or for applica-tion on a surface to form a sound-damping and/or insulat-; ing layer thereon.
It is a primary object of this invention to provide an additive of cellular plastic type to be mixed with a .. ; ~
hardening or air-drying component which ;s light, cheap and can be mixed with most prefabricated standard paints, filling compounds, adhesives, etc.
It is a further object of this invention to provide an additive which is neutral, i.e. an additive which has no adverse affect on the compound with which it is to be mixed.
A still further object of this invention is to pro-vide a method for manufacturing the additive of cellular plastic type, by which a homogeneous mixture of the com-ponents included into the additive is obtained.
Additional objects and advantages of the invention in part will be set forth in the descr;pt;on which fol-lows and in part will be obvious from the description, or may be learned by practice of the invention. The ob-jects and advantages of the invention may be realized and attained by means of the instrumental;ties and com-binations particularly pointed out in the appended claims.
To achieve the foregoing objects and ;n accordance w;th the purpose of the invention, as embodied and broad-ly described herein, the additive of this invention to be mixed with a hardening of air-drying component, e.g.
a liquid paint, comprises a mixture of closed cellular plastic particles, disintegrated foamed urea formalde-hyde resin, and chopped fibreglass filaments or strands.
` The invention also includes the use of the additive as a texturing agentin a liquid paint.
Preferably, marble powder is included ;nto the dis-;ntegrated foamed formaldehyde resin.
It is also preferred that the cellular plastic par-ticles forming part of the additive, cons;st of expanded polystyrene, such as Styropor. By using a mixture of closed cellular plastic particles, disintegrated urea formaldehyde resin and chopped fibreglass filaments or strands in the additive of the invention, this can easi-ly be stirred down e.g. into a paint. Then, the closedcellular plastic particles will act as the primary tex-ture developing component of the additive. The disinte-grated cured foamed urea formaldehyde resin will absorb the paint and w;ll act as a thickening agent. It will also promote a uniform distribution and deposition of the closed cellular plastic particles on the surface to be treated. The purpose of the chopped f;breglass fila-mentsor strands is to act as a reinforcement in the tex-tured layer. This reinforcement is necessary to preventcracking of the hardened or dried mixture of additive and paint or other similar liquid.
By mixing e.g. marble powder into the disintegrated urea formaldehyde resin, the latter will increase in weight, which means that it can be mixed more rapidly with the hardening or air-drying component.
It is preferred that the closed cellular plastic particles of the additive of the invention comprise ex-panded polystyrene, such as Styropor.
It is also preferred that the additive comprises, by weight, 70% cellular plastic particles, 15~ disinte-grated foamed urea formaldehyde resin and 15~ chopped fibreglass filaments or strands.
Preferably, the size of the closed cellular plastic particles ranges from 0.2 to 3.0 mm; the size of the disintegrated urea formaldehyde resin ranges from 2 to 10 mm; and the length of the chopped fibreglass filaments or strands ranges from 4 to 7 mm.
The accompanying drawing which is incorporated ;n 3รป and constitutes a part of this specification, illustrates diagrammatically a method for manufacturing the additive of the invention.
In the drawing hoppers 1, 2 and 3 for the different components of the additive are shown, i.e. the hopper 1 contains closed cellular plastic particles, the hopper 2 o contains dis;ntegrated urea formaldehyde resin and the hopper 3 contains chopped fibreglass f;laments or strands.
From these hoppers the components are supplied, e.g. by adjustable screw conveyors, to an air-convey;ng p;pe 4 in which the components form a uniform m;xture which is delivered to a silo 5. A portioning means 6 ;s diagram-matically shown at the base of the silo 5. Such means can be adjustable for cooperation with different types -of packages.
The additive of this invention has a volume/weight ratio of about 50 g/dm3 and the stor;ng-time thereof is practically unlimited. Another valuable feature of the additive is that the dried or hardened mixture in wh;ch the additive is included, can be removed easily from a 15 surface by means of a sharp-edged tool. By using this ', tool the cellular plastic particles are cut, the remain-ing paint or adhesive forming a smooth surface.
It will be apparent to those skilled in the art that various other modifications and variations in ad-dition to those mentioned above could be made with re-gard to the addit;ve of the invention and the method of manufacturing the same within the scope of the invention.
