Butadiene acrylonitrile rubber sheath formula

Abstract

The invention relates to a butadiene acrylonitrile rubber sheath formula. The formula comprises the following components: 100 parts of butadiene acrylonitrile rubber, 3 parts of polystyrene, 5 parts of ultralow density polyethylene, 6 parts of chlorinated paraffin, 6 parts of polyurethane, 2 parts of butyl acetate, 6 parts of calcined clay, 3 parts of talcum powder, 4 parts of ethylene glycol, 7 parts of phthalo blue, 3 parts of ethylene-vinyl acetate and 10 parts of dicyclopentadiene. The rubber sheath formula has the advantages of low cost, reasonable proportion, excellent performance, use stability and the like, improves the production benefits of factories and reduces the consumption of rubber, and the physical and mechanical properties of rubber sheaths are not reduced.

Description

technical field [0001] The invention relates to a chemical product, in particular to a formula for a nitrile rubber sheath. Background technique [0002] The rubber sheath is suitable for hydraulic hoses, electronic devices, moving mechanisms or locomotive parts, etc., to support and protect the internal products. It can not only improve the appearance and restraint, but also prolong the life of the internal products. The rubber content of the nitrile rubber sheath produced by the existing formula is generally about 52%. Since the price of the rubber is more expensive, the higher the rubber content, the higher the cost of the sheath. Commercially available rubber sheaths Due to its higher rubber content, the price is also more expensive. If you want to reduce the cost of the nitrile rubber sheath, you need to reduce its rubber content, and if you directly reduce the rubber content, it will inevitably affect the various properties of the nitrile rubber sheath. Due to raw mat...

Problems solved by technology

The rubber content of the nitrile rubber sheath produced by the existing formula is generally about 52%. Since the price of the rubber is more expensive, the higher the rubber content, the higher the cost of the sheath. Commercially available rubber sheaths Due to its higher rubber content, the price is also more expensive

If you want to reduce the cost of the nitrile rubber sheath, you need to reduce its rubber content, and if you directly reduce the rubber content, it will inevitably affect the various properties of the nitrile rubber sheath. Due to raw materials, manufacturing processes or human factors, at present Most of the rubber sheaths on the market are often aging, deformed, damaged, etc.
