O-shaped ring for automobile

Abstract

The invention provides an O-shaped ring for an automobile. The O-shaped ring material comprises the following components in parts by weight: 15-30 parts of natural rubber, 15-20 parts of synthetic resin, 20-40 parts of polyurethane, 2-3 parts of micron sized silica aerogel, 1-3 parts of sodium antimonate, 1-3 parts of jade powder, 2-7 parts of diisononyl phthalate, 3-7 parts of inorganic silicate material, 2-5 parts of zinc borate, 3-7 parts of zinc oxide, 1-3 parts of stearic acid, 4-8 parts of zinc methacrylate, 3-6 parts of plasticizer, 3-8 parts of zinc diethyl dithiocarbamaate, 1-6 parts of anti-aging agent, 5-15 parts of butadiene-styrene rubber, 1-3 parts of accelerant, 0.5-1 part of benzoic acid, and 3-8 parts of high abrasion furnace black. The O-shaped ring for an automobile provided by the invention is high in strength, excellent in wear-resisting property, good in oil resistance and solvent resistance, and especially good in swelling resistance for lubricating oil and fuel oil, and good in ozone resistance; and the service life and the product performance stability of the O-shaped ring for the automobile are improved.

Description

technical field [0001] The invention relates to the technical field of pipe processing and production of raw materials, in particular to an O-ring for automobiles. Background technique [0002] Plastic is a synthetic polymer material with a wide range of uses, and plastic products abound in our daily life. From the toiletries we use after we wake up, the tableware we use for breakfast, to the stationery we use for work and study, the seat cushions and mattresses we use for rest, as well as the shells of TVs, washing machines, computers, and the night brings us Bright lamps of various shapes... [0003] With its excellent performance, plastic has gradually replaced many materials and utensils that have been used for decades or hundreds of years, and has become an indispensable assistant in people's life. Plastic combines the hardness of metal, the lightness of wood, the transparency of glass, the corrosion resistance of ceramics, and the elasticity and toughness of rubber. ...

Problems solved by technology

[0004] Plastics are used to make O-rings for automobiles. In the prior art, most of the plastic materials selected for O-rings for automobiles are thermoplastic resins. Thermoplastic resins have the properties of softening by heat and hardening by cooling, and do not react chemically. , no matter how many times heating and cooling are repeated, this performance can be maintained, but plastics made of thermoplastic resins have poor heat resistance and rigidity, low mechanical properties, and low ozone resistance, heat resistance, and corrosion resistance. Poor, which affects the physical and mechanical properties and service life of O-rings for automobiles
