Abstract

The invention discloses anticorrosion anti-aging rubber and a preparation method thereof. The rubber is prepared from the following raw materials: 80 to 120 parts of natural rubber, 10 to 15 parts ofbutadiene-acrylonitrile rubber, 30 to 40 parts of styrene butadiene rubber, 5 to 10 parts of glycerinum, 0.5 to 1 part of talcum powder, 1 to 5 parts of aluminum oxide, 3 to 9 parts of graphite, 2 to6 parts of sodium chloride, 10 to 15 parts of reinforcing filler, 1 to 5 parts of vulcanizing active agent, 0.5 to 1 part of vulcanizing agent, 1 to 2 parts of vulcanization accelerant, 2 to 5 parts of plasticizer, and 0.5 to 2 parts of anti-aging agent. The anticorrosion anti-aging rubber has the following advantages that: (1) the corrosion resistance is high, strong acid and strong alkali can beresisted, and the substitution reaction is unlikely to occur; (2) the wide temperature range adaptability is good, and the application requirement of the wide temperature range can be met; (3) the quality is reliable, and the durability is realized; and (4) the cost is low, the preparation is simple, and the large-scale production can be realized.

Description

technical field [0001] The invention relates to a rubber, in particular to a corrosion-resistant and aging-resistant rubber and a preparation method thereof. Background technique [0002] The rubber industry is one of the important basic industries of the national economy. It not only provides daily and medical light industrial rubber products that are indispensable for people’s daily life, but also provides various rubber production equipment or rubber parts for mining, transportation, construction, machinery, electronics and other heavy industries and emerging industries. It can be seen that the rubber industry has a wide variety of products, and the backward industry is very broad. In recent years, the rubber industry has developed a lot. The existing sub-sectors have grown steadily, while the new rubber sub-sectors have developed rapidly. However, at the same time, the rubber industry still has problems such as the environment, resources, disasters, and innovation. [...
