Abstract

The invention relates to the production of waterproofing polymer-bitumen materials with a sticky adhesive layer and can be used in the building materials industry. The invention makes it possible to increase the strength of a material by 50-55%, by 2.5 times the elongation, 2 times the adhesion of the material to the insulated surface due to the preliminary application at 140-180 ° C of an adhesive layer melt that includes (in wt.%) 57 bitumen, 15 butyl rubber, 10 petroleum oil, 17 talcum, 1 anthracene oil, 1.55-1.60 mm thick on an anti-adhesive gasket - siliconized paper or polyethylene terephthalate film, and cooling it to 40-70 ° C, followed by duplicating it between two rolls at a pressure of 5-15 kg / cm ^2, polymer-bitumen mp nkoya people, consisting of (in wt.%) 42 bitumen, polyisobutylene 27 15 High density polyethylene, low density polyethylene 15, 1 anthracene oil. 2 tab.

Description

The invention relates to waterproofing polymer-bitumen materials with a sticky adhesive layer and can be used in the building materials industry.

The purpose of the invention is to improve the physicomechanical properties of the waterproofing material and its adhesion to the insulated surface.

The method is carried out as follows.

The polymer-bitumen film (PBP) is made successively on a line consisting of a mixer, rollers, an extruder, a calender.

The mixture for PBP is prepared in a rubber mixer according to the following recipe, wt%:

In this case, the bales of polyisobutylene cut into pieces are weighed and fed into a rubber mixer. Polyethylene is weighed and fed into a rubber mixer, weighted and loaded with bitumen in three steps successively, at the end of mixing an antiseptic is added.

The whole mixing cycle lasts 40-45 minutes. The temperature of the finished mixture 130-160 ° C.

The finished polymer-bitumen mixture from the rubber mixer is fed to the rollers for kneading and homogenization. Remove the hot mixture from the rolls into a syringe machine with a slit head. The film web coming out of the slit head is fed to a calender where it is calibrated after

In the manufacture of glue in a preheated mixer serves a portion of the bitumen, industrial oil, load rubber and filler. The components are mixed until a uniform mixture is obtained, then the remaining bitumen is introduced in two steps. Together with the last batch of bitumen load antiseptic. The mixing temperature is 120-140 ° C, the mixing time is 2.5-3.0 hours.

The finished glue is discharged from the mixer and at 140-180 ° is applied with a roller machine on siliconized paper (SB) or polyethylene terephthalate film (PET), which is unwound from the roll and fed to the conveyor. The conveyor belt is constantly treated with talc suspension to cool the glue (adhesive layer), from the top side the adhesive layer is cooled with air to 40-70 ° C. The cooled sticky layer on the SB serves in the gap between the rolls of the calender, which receives the finished PBP. o Between rolls of the calender, PBP is duplicated with a sticky layer through the SB, after which the material is ready and wound into rolls.
