Problems solved by technology

Although the airbag made of neoprene has good flexibility, it has poor cold resistance and can only be used at temperatures below minus 30°C. If it is lower than this temperature, the rubber will crystallize, making the product hard and brittle , lose the elasticity that rubber should have, and cracks will occur when flexing, so that the airbag is scrapped due to air leakage; although the airbag using natural rubber has better overall performance, because the medium used in the airbag is oily air, natural The rubber will gradually swell under the action of this medium, so that the strength of the rubber material will become lower, the flexibility will be worse, and the service life will be greatly reduced, which cannot meet the needs of customers.

Abstract

The invention discloses a cold-resistant rubber material suitable for preparing an air sac and a preparation method thereof. The invention utilizes and integrates the favorable cryogenic property (the brittleness temperature can be minus 105 DEG C) of butadiene rubber, the excellent flexing resistance and the adhesiveness of neoprene and the favorable processability of natural rubber so as to produce the cold-resistant rubber material which is suitable for preparing the air sac and has high strength, favorable cryogenic property, certain oil resistivity, better flexing resistance and favorable technological processability.

Description

technical field [0001] The invention relates to a cold-resistant rubber material suitable for making air bags and a preparation method thereof. Background technique [0002] Airbags are widely used in automobiles, petroleum machinery, road construction machinery and other fields. The main rubber materials of airbags used in the market are generally two kinds of neoprene and natural rubber. Although the airbag made of neoprene has good flexibility, it has poor cold resistance and can only be used at temperatures below minus 30°C. If it is lower than this temperature, the rubber will crystallize, making the product hard and brittle , lose the elasticity that rubber should have, and cracks will occur when flexing, so that the airbag is scrapped due to air leakage; although the airbag using natural rubber has better overall performance, because the medium used in the airbag is oily air, natural The rubber will gradually swell under the action of this medium, so that the strengt...
