Corrosion-resistant rubber pipe material

Abstract

The invention discloses a corrosion-resistant rubber pipe material. The corrosion-resistant rubber pipe material is characterized by being prepared from the following raw materials in parts by weight: 30-40 parts of ethylene propylene rubber, 25-30 parts of solution polymerized styrene-butadiene rubber, 15-20 parts of an SRR-16 reclaimed rubber, 1-2 parts of benzoyl peroxide, 3-4 parts of an NXT silane coupling agent, 4-7 parts of nano-graphite, 7-9 parts of paraffin, 3-4 parts of talc, 0.7-0.9 part of zinc oxide, 0.6-0.8 part of zinc stearate, 2-4 parts of epoxy resin, 0.7-0.9 part of cyclohexane-1,6-sodium dithiosulfate, 1.5-1.8 parts of titanium dioxide, 1-3 parts of white oil, 0.3-0.5 part of an antioxidant AT-10, 0.8 part of butylated hydroxytoluene and 2-4 parts of sulfur. The prepared corrosion-resistant rubber pipe material is good in resistance and tolerance to various polar chemicals including acids, alkalis and oxidant, low in aging rate, low in cost, excellent in product performance and wide in application prospect.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and in particular relates to a corrosion-resistant rubber tube material. Background technique [0002] Ethylene propylene rubber is a kind of rubber with a lower density, and its density is 0.87. In addition, a large amount of oil can be filled and fillers can be added, so the cost of rubber products can be reduced, and the disadvantage of high price of raw ethylene-propylene rubber is made up for. For ethylene-propylene rubber with high Mooney value, the physical and mechanical properties of high-filling are reduced. Not much. [0003] Due to the lack of polarity and low degree of unsaturation of ethylene-propylene rubber, it has good resistance to various polar chemicals such as alcohols, acids, alkalis, oxidants, refrigerants, detergents, animal and vegetable oils, ketones and fats, etc. ; But in aliphatic and aromatic solvents (such as gasoline, benzene, etc.) and poor stability in...

Problems solved by technology

[0008] However, with the rapid development of modern industry, the environmental conditions of industrial products are getting worse and worse, and higher requirements are put forward for the performance of products. However, reclaimed rubber has its own defects such as poor elasticity and tear resistance. The products produced after adding are often difficult to meet the performance requirements, which largely restricts its use in industrial products
