Abstract

The invention belongs to the field of preparation of rubber materials, and in particular, relates to an alkali-resistant rubber material. The material is composed of the following raw materials in parts by weight: 20-25 parts of an ethylene propylene diene monomer, 80-90 parts of fluororubber, 15-20 parts of fluorosilicone rubber, 10-12 parts of liquid acrylonitrile-butadiene rubber, 20-30 parts of polycaprolactone, 15-20 parts of fumed silica, 0.4-0.8 part of an accelerator, 4-5 parts of an anti-aging agent, 2-5 parts of nano zinc oxide, 5-13 parts of nano titanium dioxide, 0.5-0.8 part of tert-butyl peroxybenzoate, 0.1-0.6 part of dibenzoyl peroxide, 2-3 parts of alpha,omega-dihydroxy polydimethylsiloxane, and 12-15 parts of a nickel slag alkali-resistant reinforcing material. Through choice of the type of rubber and addition of the alkali-resistant reinforcing material, the strength and alkali resistance of the rubber material are significantly enhanced.

Description

technical field [0001] The invention belongs to the field of rubber material preparation, in particular to an alkali-resistant rubber material. Background technique [0002] Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. After decades of hard work, China has developed into a leader in the world's rubber industry. Since 2002, it has maintained the world's largest annual rubber consumption for three consecutive years. Since 2003, tire production has been second only to the United States in the world. Rubber products such as rubber hoses, tapes, and rubber shoes are also among the best in the world. Rubber products are widely used in all aspects of industry or life. [0003] Due to the different uses of rubber materials, the requirements for their performance are also different. Commonl...
