Description

The invention relates to the production of multilayer covering tent polymer materials and can be used in the manufacture of tent materials and other reinforced materials used in the construction of prefabricated structures and shelters of vehicles used in various climatic zones, including in the Far North.

Known tent materials based on polyester fabrics with double-sided application of polyvinyl chloride compositions (RU 585094A) have a high linear density of the threads, which leads to their heavy weight, which makes them difficult to use.

Awning materials with a double-sided coating for vehicles (GOST 29151-91) are also known, obtained on the basis of polyester fabric with plain weaving of threads with a linear density of 27.7-111 tex with the number of elementary threads in the complex 48-192 and the number of torsions 160-280 cr / m (art. 56387; 56303; 56235 according to GOST 26369-84, 27507-87, 27507-89 and TU 17-04-15-248-90). However, they also have the above disadvantages.

The objective of the invention is the creation of a multilayer covering, tent polymer material suitable for use in the construction of prefabricated structures and shelters of motor vehicles in accordance with the requirements of the Ministry of Defense of the Russian Federation.

The essence of the invention lies in the fact that as the basis for a multilayer material consisting of a polyester flat-knitted fabric with a double-sided coating, use a polyester complex thread 100-111 tex, with the number of elementary threads (filaments = 1) in the complex 200-400 and the number of torsions 85-100 cr / m, while the mass ratio of the layers is front: intermediate: wrong - 1.1: 1: 1.6, respectively, while the mass ratio of the polyester base and the PVC coating is 1: 2.7.

To achieve static and dynamic frost resistance, a polymer coating based on suspension polyvinyl chloride with Fikentcher constant 70-72 additionally contains a mixture of plasticizers - dioctyl phthalate (DOP) and dioctyl sebacinate (DOS); ViturT thermoplastic polyurethane;

BNKS-28 brand nitrile butadiene rubber; a copolymer of methyl methacrylate, butadiene and styrene brand KANE ACE B28A in a ratio of 1: 1.3: 1.7: 0.7: 0.6, respectively. The stabilizer is a complex barium-cadmium-zinc-containing stabilizer brand Vigostab BCC. The antipyretic additive is made in the form of a mixture of antimony trioxide and chlorinated paraffin brand ХП-1100 in a ratio of 1: 1, salicylic acid fungicide-anilide. The composition also contains a technological additive: stearic acid and pigments, and the quantitative composition is selected with the following parts by weight (or wt.%):
