Technical Field

The invention relates to the field of preparation of rubber product raw materials, and particularly relates to antioxidant rubber.

Background

The 'paraffin' is separated out after the rubber or the plastic is parked for a long time, the paraffin is a rubber compounding agent and mainly has the functions of preventing (reducing) the oxygen aging and the ozone aging of the rubber and prolonging the service life of the rubber, the paraffin separation of the general rubber is more obvious than that of the plastic, and the content of the paraffin in a rubber formula is much higher than that of the plastic because the rubber is easier to be oxidized by oxygen and becomes soft, sticky or becomes hard and cracks (which is related to the type of the rubber) than the plastic, namely the paraffin is separated out more obviously

Disclosure of Invention

In order to solve the problem that the paraffin is easy to separate out when the rubber is placed for a long time, the invention provides the following technical scheme:

an antioxidant rubber is composed of the following components in parts by weight: 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 retarder, 3-5 parts of a softener, 1-5 parts of aromatic oil, 2-4 parts of ethylhexyl phthalate, 2-4 parts of simethicone and 3-5 parts of calcium carbonate.

Further, the coating comprises the following components in parts by mass: 70 parts of butyl rubber, 40 parts of chlorohydrin rubber, 65 parts of fluorosilicone rubber, 140 parts of natural rubber, 4 parts of palm wax, 6 parts of glycerol, 120 parts of carbon black, 7.5 parts of antioxidant, 4 parts of anti-scorching agent, 4 parts of softener, 3 parts of aromatic oil, 3 parts of ethylhexyl phthalate, 3 parts of dimethyl silicone oil and 4 parts of calcium carbonate.

Further, the coating comprises the following components in parts by mass: 60 parts of butyl rubber, 30 parts of chlorohydrin rubber, 50 parts of fluorosilicone rubber, 80 parts of natural rubber, 3 parts of palm wax, 4 parts of glycerol, 5 parts of carbon black, 5 parts of an antioxidant, 3 parts of a scorch retarder, 3 parts of a softener, 1 part of aromatic oil, 2 parts of ethylhexyl phthalate, 2 parts of dimethyl silicone oil and 3 parts of calcium carbonate.

Further, the coating comprises the following components in parts by mass: 80 parts of butyl rubber, 50 parts of chlorohydrin rubber, 80 parts of fluorosilicone rubber, 200 parts of natural rubber, 5 parts of palm wax, 8 parts of glycerol, 20 parts of carbon black, 10 parts of antioxidant, 5 parts of anti-scorching agent, 5 parts of softener, 5 parts of aromatic oil, 4 parts of ethylhexyl phthalate, 4 parts of dimethyl silicone oil and 5 parts of calcium carbonate.

Further, the sodium borate preservative also comprises 3-4 parts of sodium pentaborate.

The invention has the beneficial effects that: the palm wax and the glycerol are adopted to replace the traditional paraffin and sulfur, so that the phenomenon of paraffin precipitation of the rubber can be avoided, the rubber is prevented from deteriorating, and the service life of the rubber is prolonged.
