(57) Abstract:

The invention relates to construction materials, namely, roll finishing materials for walls based on polymers with a picture of the crumb. The polymer mass is applied on the underlying cause, carry out a preliminary heat treatment, using the dosing device is applied mineral aggregate and perform another pre-heat treatment, the material is compacted and conduct a final heat treatment and foaming the polymer mass. 1 Il.

The invention relates to the production technology of construction materials, including finishing materials for walls on a polymer basis.

A method of obtaining a finishing material for walls (PVC), foam, paper-based, through preparation of plastisol compositions based on PVC containing plasticizer, stabilizer, blowing agent, filler, initiator decomposition of the blowing agent, heat treatment, in which the gelation and foaming with subsequent mechanical embossing of foamed plastic. However, as returned by this method of finishing materials are flammable and are characterized by a large fire.

This method allows to obtain coatings with the use of a polymer, such as polyvinylchloride, granules and filling the space between the granules of the composition unfilled PVC plastisol, which can be used more as a floor covering with a top layer of polyvinylchloride composition with a mosaic pattern of polymer granules.

However, obtaining a finishing material for walls with mineral granules (chips) in this way, because the application of polymer mass on top of the mineral aggregate will reduce the resistance of the material and will worsen its decorative properties.

This objective is achieved in that in the method of obtaining a roll of finishing material of the chips, including the application of a moving subbase aggregates and polymer mass, the seal material and heat treatment crumbs use mineral 0.5-4.0 mm as a polymeric mass - polyvinyl chloride plastisol composition containing a blowing agent in a quantity of 1.0 to 3.0 wt. hours at 100 wt. including polyvinyl chloride, with the first on the subbase put a layer of polymer mass and will conduct the heat treatment at the temperature of gelation polymer mass, then apply mineral powder and conduct another preliminary heat treatment at the same temperature, the material is compacted and make final heat treatment with a foaming polymer mass at the temperature of decomposition of the blowing agent.

Applying a layer of mineral aggregate on the proposed method is carried out with a measuring device, consisting of a hopper, calibrating shaft tlaut as follows: first, a mixture is prepared plastisol composition (polymer weight), consisting of emulsion polyvinyl chloride, plasticizer, filler (usually chalk or hydrate of aluminum oxide), a stabilizer and a blowing agent (usually azodicarbonamide - porofor CHS-21), activator decomposition of poroporo (zinc oxide or titanium dioxide). The song serves a pump of the pump device. The crushed mineral stone is usually 0.5-4.0 mm (granite, marble, fired perlite, vermiculite, mica) different colors are pre-mixed among themselves, and fed into the hopper 2.

On the basis of 3 put a layer of polyvinylchloride paste with a thickness of 0.4-0.8 mm, carry out his preliminary heat treatment, for example, using an infrared heater, and then using a special measuring device, consisting of a hopper, calibrating roller and conveyor feeder, put a layer of mineral aggregate, hold a preliminary heat treatment using an infrared heater 4, condense the material using a roller pressing device 5 and carry out a final heat treatment in a heat chamber 6, while the polymer mass foams, firmly securing mineral powder; next, after cooling the material cold air it is wound into a roll for winding Wickliffe (DOP), to 25.0 wt. including dialkylphosphate (DUFF), 60,0 wt. including chalk, 2.5 wt. hours of porofor CHS-21 (pre-grinded with DOP in the ratio 1: 1), 2.0 wt. including stabilizer (barium-cadmium stearinovokisly and produce a mixture of these components within 30 minutes

Next, on the basis of non-woven laminated fabric, put on alluvial device prepared polymer mass thickness of 0.4 mm and produce a preliminary heat treatment, passing the fabric under an infrared heater; put a layer of mineral aggregate with a measuring device, consisting of a hopper, calibrating roller and conveyor-feeder, when this set is the speed ratio of the belt feeder and the moving web to mineral grit fit in one layer.

Produce a preliminary heat treatment of a cloth, passing it under an infrared heater for catching crumbs and polymer mass, compact the material on the device stitcher and produce heat treatment of material in a heat chamber and foamed at 180aboutC. the speed of the blade is 5 m/min after cooling of the material by cold air produce a winding finishing material.
