Description

(5 |) POLYMERNA COMPOSITION FOR PRODUCING FILM The invention relates to the plastics industry and can be used to produce a rigid film material for various purposes based on polyvinyl chloride (PVC) and acrylonitrile butadiene styrene terpolymer (ABS). It is known to use polyvinyl chloride and ABS copolymer as leather fancy goods and structural material f1. However, the processing of compositions based on these polymers on roller equipment is difficult, and the film materials obtained from them have insufficiently high physicomechanical indicators. The closest to the proposed composition and the achieved result is a polymer composition for the preparation of a film material containing a polymer binder — a mixture of polyvinyl chloride and a copolymer of acrylo-nitrile, butadiene and styrene in the MATERIAL ratio t :, plasticizer, complex barium-cadmium stabilizer and pigment 2 However, the physicomechanical characteristics of film materials obtained on its basis deteriorate significantly during operation when exposed to elevated temperatures, oxygen and UV rays and anise. tropic of properties. The purpose of the invention is to increase the stability of the composition to the combined effect of the prevailing temperatures and oxygen of the air and preserve the original properties of the films in two directions. The above objective is achieved in that a polymer composition for the preparation of a film material containing a polymer binder mixture of polyvinyl chloride and a copolymer of acrylonitrile, butadiene and. styrene in a 4: 1 ratio, plate (| ikator, complex barium-cadmium stabilizer and pigment; organic phosphite and organotin tin are also added)

Swelling and mixing are carried out in Henschel type turbospeed mixers or two-stage mixers at VO-SOO C for 1015 minutes. Next, the swollen polymer composition is treated in an intensive heavy type mixer with pr IZO-IBO C for 3 min. After that, the mixture is rolled and then a film 0.45-0.55 mm thick is formed on the calender. The calendering temperature is 1b5-175C.

The formulation of the known and proposed polymer compositions are given in table. one.

In tab. 2 shows the properties of the known and proposed composition.

As can be seen from the data table. 2 the introduction of the proposed additives tin-silicon organic compound, together with organic phosphite, allows to improve the performance levels

increase the stability of the polymer composition to obtain a film material to elevated processing temperatures, UV rays and air oxygen.

The introduction of an OKOS together with an organic phosphite makes it possible to obtain polymer films with equal strength properties in two directions.
