Isobutylene and EPDM rubber composite rubber frosting-resistant anti-aging agent and preparation method thereof

Abstract

The invention discloses an isobutylene and EPDM rubber composite rubber frosting-resistant anti-aging agent. The isobutylene and EPDM rubber composite rubber frosting-resistant anti-aging agent is prepared from components in parts by weight as follows: 40-70 parts of isobutylene, 2-5 parts of a dispersant, 15-30 parts of an inorganic silicon material, 15-30 parts of a masterbatch carrier, 20-40 parts of dilauryl thiodipropionate, 10-30 parts of superfine calcium carbonate, 30-50 parts of 4-methyl-2-pentanone and 10-20 parts of 4-amino diphenylamine. The isobutylene and EPDM rubber composite rubber frosting-resistant anti-aging agent adopts a reasonable formula and a scientific process, has excellent heat resistance, oxidation resistance, flexing resistance and frosting resistance and is pollution-free, healthy, environmentally friendly, low in cost and suitable for large-scale promotion.

Description

technical field [0001] The invention belongs to the technical field of rubber anti-vomiting anti-aging agents, and more specifically relates to a rubber anti-vomiting anti-aging agent compounded with isobutylene and ethylene-propylene rubber. At the same time, the invention also relates to a preparation method of a rubber anti-vomiting cream anti-aging agent compounded with isobutylene and ethylene-propylene rubber. Background technique [0002] At present, the common rubber antioxidants on the market include 6PPD, RD, 4010NA, 4030 and other models. 6PPD and 4010NA antioxidants are suitable for natural rubber, styrene-butadiene rubber, nitrile rubber, butadiene rubber and other synthetic rubbers. The early anti-aging effect is ideal. However, it is slightly worse in the later stage. Due to the lack of solubilizing genes on the benzene rings on both sides of the structure, blooming phenomenon is prone to occur when there is a large amount in the rubber compound; due to the hi...

[0002] At present, the common rubber antioxidants on the market include 6PPD, RD, 4010NA, 4030 and other models. 6PPD and 4010NA antioxidants are suitable for natural rubber, styrene-butadiene rubber, nitrile rubber, butadiene rubber and other synthetic rubbers. The early anti-aging effect is ideal. However, it is slightly worse in the later stage. Due to the lack of solubilizing genes on the benzene rings on both sides of the structure, blooming is prone to occur when there is a large amount in the rubber compound; due to the high alkalinity, it has a greater impact on vulcanization and scorch time

With the increasing scope of use of rubber products and the increasingly harsh conditions of use, rubber manufacturers have higher and higher requirements for anti-aging agents. Traditional anti-aging agents have been phased out because they are harmful to human health during use, and the market price is relatively high. , increasing the cost of rubber production enterprises
