Lignin reinforcing filled butadiene-acrylonitrile rubber hose

Abstract

The invention discloses a lignin reinforcing filled butadiene-acrylonitrile rubber hose which mainly comprises a lignin reinforcing filled butadiene-acrylonitrile rubber blended elastomer, sulfur, zinc oxide, stearic acid, a accelerant, an anti-aging agent and the like. The lignin reinforcing filled butadiene-acrylonitrile rubber hose has the advantages of high mechanical strength, favorable oil resistance, high adhesion strength with framework materials, such as steel wires and the like; and the finished product has the characteristics of light weight, high pulse resisting capacity and long service life, and can reduce the material cost and the environmental pollution.

Description

technical field [0001] The invention relates to the field of rubber hose products, in particular to a nitrile rubber hose filled with lignin reinforcement. Background technique [0002] Rubber hose is a tubular rubber product, mainly used to transport gas, liquid, slurry or granular materials, because of its advantages of easy bending, cushioning, light weight and convenient installation and use, it is widely used. The rubber hose is composed of an inner rubber layer, a skeleton layer and an outer rubber layer: the inner rubber layer directly bears the wear and erosion of the conveying medium, and plays a role in preventing the medium from leaking; the skeleton layer is the pressure-bearing layer of the rubber hose, giving the pipe body strength and rigidity; The outer rubber layer protects the skeleton layer from external damage and erosion. [0003] Nitrile rubber has excellent oil resistance, heat resistance and physical and mechanical properties, and can be used to prod...

Problems solved by technology

However, carbon black, a reinforcing filler for rubber, is mainly made of ethylene tar or coal tar with high aromatic content and low impurity and asphalt content. Among them, ethylene tar is a product of petroleum refining, and coal tar is an important product of the coking industry, both of which belong to Non-renewable resources; the coking industry is still an industry that pollutes the environment more seriously; the use of carbon black to reinforce and fill rubber will produce a large amount of carbon black dust pollution in the production process, which is a traditional pollution source in the rubber processing process and is difficult to cure. The pneumoconiosis caused is also an occupational disease in the rubber industry, which has long endangered the health of employees.
