Abstract

The invention relates to antioxidant rubber which is mainly prepared from the following components in parts by mass: 60-80 parts of butyl rubber, 30-50 parts of chlorohydrin rubber, 50-80 parts of fluorosilicone rubber, 80-200 parts of natural rubber, 3-5 parts of palm wax, 4-8 parts of glycerol, 5-20 parts of carbon black, 5-10 parts of an antioxidant, 3-5 parts of a scorch inhibitor, 3-5 parts of a softener, 1-5 parts of aromatic oil, 2-4 parts of monoethylhexyl phthalate, 2-4 parts of dimethyl silicone oil and 3-5 parts of calcium carbonate. The palm wax and the glycerol are adopted in therubber to replace traditional paraffin wax and sulfur, so that the phenomenon of paraffin wax ''precipitation'' can be avoided in the rubber, the deterioration of the rubber can be prevented, and theservice life of the rubber can be prolonged.

Description

technical field [0001] The invention relates to the field of raw material preparation of rubber products, in particular to an anti-oxidation rubber. Background technique [0002] Rubber or plastic will precipitate 'paraffin wax' after long-term parking. Paraffin wax is a rubber compounding agent. Its main function is to prevent (reduce) the oxygen aging and ozone aging of rubber and improve the service life of rubber. The paraffin wax precipitation ratio of general rubber Plastic is obvious, because rubber is more likely to be oxidized by oxygen than plastic to become soft, sticky or hard and cracked (this is related to the type of rubber). Therefore, the content of paraffin in the rubber formula is much higher than that of plastic, that is, the precipitation is more obvious. Contents of the invention [0003] In order to solve the problem that rubber is easy to precipitate out of paraffin wax after a long period of time, the present invention provides the following techni...
