Abstract

The invention discloses a sealing part for an automobile heat radiator. The sealing part is prepared from the following raw materials in parts by weight: 15-25 parts of fluorous rubber, 20-40 parts of epichloro-hydrin rubber, 8-16 parts of chloroprene rubber, 1-2 parts of dicumyl peroxide, 0.2-0.6 part of triallyl isocyanurate, 1-2 parts of zinc dimethacrylate, 1-4 parts of methylphenyldiethoxysilane, 1-2 parts of polydimethylsiloxane, 2-6 parts of modified bamboo fibers, 5-15 parts of aluminum borate whiskers, 10-14 parts of aluminum oxide, 2-6 parts of anthracite coal, 2-8 parts of apatite, 5-12 parts of attapulgite, 1-2 parts of magnesium oxide, 2-4 parts of chlorinated paraffin, 0.5-1.2 parts of magnesium stearate and 1-2 parts of dioctylterephthalate. The sealing part disclosed by the invention has excellent wear resistance and toughness and also has a very good high-temperature-resisting performance; and meanwhile, the sealing part is not easy to age and the service life is long.

Description

technical field [0001] The invention relates to the technical field of seals, in particular to a seal for automobile radiators. Background technique [0002] In recent years, with the rapid economic growth, the rubber and plastic seal manufacturing industry has maintained double-digit growth. The scale of China's rubber and plastic seal manufacturing industry has achieved a total industrial output value of nearly 10 billion, a year-on-year increase of more than 20%. According to the material classification, it is divided into nitrile rubber, EPDM rubber, fluorine rubber, silica gel, fluorosilicone rubber, nylon, polyurethane, engineering plastics, etc. Currently, it has been well used in automobile radiators, but automobile radiators are resistant to resistance. The requirements for tearing and wear resistance are relatively high, and the existing general rubber sealing surface still meets a lot of needs, which needs to be solved urgently. SUMMARY OF THE INVENTION [000...
