Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the existing nitrile rubber anti-aging agent uses nonylphenol anti-aging agent, which is not environmentally friendly, greatly restricts the use amount and the scope of use of nitrile rubber, and provides a kind of anti-aging agent suitable for the production and use of nitrile rubber. Environmentally-friendly rubber anti-aging agent with excellent anti-aging effect and little pollution to the environment

Abstract

The invention discloses an environmentally-friendly rubber anti-ageing agent and a preparation method thereof, which are used for overcoming the defect that the using amount and use range of butadiene nitrile rubber are constrained greatly since a nonyl phenol anti-ageing agent which is not environmentally-friendly is taken as an anti-ageing agent of the conventional butadiene nitrile rubber. The environmentally-friendly rubber anti-ageing agent disclosed by the invention is prepared by compounding an antioxidant 2246, polybutyl bisphenol, tri(nonylphenyl)phosphite ester and disproportionate potassium rosinate in the weight ratio of 1:(1.5-3):(1.5-3):(2-3.5). The environmentally-friendly rubber anti-ageing agent has an excellent anti-ageing effect and very low environmental pollution.

Description

technical field [0001] The invention relates to a rubber anti-aging agent, in particular to an environment-friendly rubber anti-aging agent for the production of nitrile rubber and a preparation method thereof. Background technique [0002] During long-term storage and use of rubber and its products, due to the effects of heat, oxygen, ozone, variable-valent metal ions, mechanical stress, light, high-energy rays, and other chemical substances and molds, etc., they will gradually become sticky and change. Hard and brittle or cracked. This decrease in physical and mechanical properties and elasticity over time is called aging. With the progress and development of the aging process, the performance of rubber and its products will gradually decrease so that it will completely lose its use value. For this reason, it is necessary to add certain chemical substances to rubber and its products to improve its resistance to the above-mentioned various destructive effects, delay or in...
