Description
Technical field
The present invention relates to rubber materials, are exactly a kind of preparation methods of wear-resisting low temperature resistant rubber.
Background technique
Natural rubber is one kind with cis- Isosorbide-5-Nitrae-polyisoprene natural polymer as main component, ingredient
In 91%~94% be rubber hydrocarbon (cis- Isosorbide-5-Nitrae-polyisoprene), remaining is the nonrubbers such as protein, fatty acid, ash content, carbohydrate
Substance.Natural rubber is most widely used general purpose rubber.
Natural rubber is widely used in manufacturing sebific duct, in damping products.It is easy at low temperature because natural rubber has
Just lose elasticity and hardness and the low disadvantage of wearability.It is badly in need of having new technology to improve the resistance to of natural rubber at present
The disadvantage of cryogenic property wear-resisting property difference, so as to which the production for being preferably applied to sebific duct and cushioning product prepares neck
Domain.
