Problems solved by technology

[0003] In the present invention, the above-mentioned three kinds of polymer materials are compounded and used together to refine the inner layer rubber of the high-pressure braided hose. By using the NBR / PVC rubber-plastic alloy that has been compounded and modified for mixing, it can solve the problem of high-pressure steel wire braiding. During the production process of rubber hose, there are quality problems such as rushing and tightening the hose, solving the melting problem of PVC and nitrile rubber, improving the solvent resistance of hydraulic hoses, and effectively controlling the cost of raw materials for hoses

Abstract

The invention relates to high-pressure braided-hose inner-layer rubber. As compositely-modified NBR / PVC rubber and plastic alloy is mixed, the quality problems of hose shifting, hose pinching and the like in the production process of a high-pressure steel-wire braided rubber hose can be well solved, the fusing problem of PVC and nitrile butadiene rubber is solved, the solvent resistance of a hydraulic rubber hose is improved, and the cost of a raw material of the rubber hose can be effectively controlled. The made high-pressure braided-hose inner-layer rubber has excellent oil resistance and excellent solvent resistance; meanwhile, processing difficulty can be greatly lowered, the stability of the quality of a product can be improved, and the cost of the raw material of the rubber is further optimized.

Description

technical field [0001] The invention relates to a rubber formula, in particular to an inner layer rubber of a high-pressure braided hose. technical background [0002] Nitrile rubber is a kind of oil-resistant rubber with strong polarity. Polyvinyl chloride has excellent solvent resistance and aging resistance. At the same time, it can effectively improve the Green hardness of the mixed rubber. Filling performance can reduce processing difficulty and production cost, and improve the bonding strength between inner rubber and steel wire. Contents of the invention [0003] In the present invention, the above-mentioned three kinds of polymer materials are compounded and used together to refine the inner layer rubber of the high-pressure braided hose. By using the NBR / PVC rubber-plastic alloy that has been compounded and modified for mixing, it can solve the problem of high-pressure steel wire braiding. In the production process of rubber hose, there are quality problems such ...
