RUBBERIZED MATERIAL (VERSIONS) Russian patent published in 2024 - IPC B32B25/10 

FIELD: various technological processes.

SUBSTANCE: invention relates to production of rubberized materials for making articles – soft containers, which are intended for packing, transportation of loose products and their temporary storage at cargo accumulation sites. Rubberized material is a layered structure consisting of three layers. As a textile base, it contains one layer of polyester fabric with a rubber coating on the front and back sides, based on a combination of ethylene-propylene diene, butadiene and butadiene methylstyrene rubber in weight ratio of 30:30:40, respectively. In another version, the rubber coating on the back side is made on the basis of natural rubber, in the third version – on the front and back sides on the basis of butadiene methylstyrene rubber.

EFFECT: invention allows maintaining elasticity of material at low temperatures, providing material with low loss of volume during abrasion, good resistance to action of 50 % acids and alkalis, weather resistance, strength of adhesion to textile base.
