Acid-and-alkali-resistant automobile rubber hose

Abstract

An acid-and-alkali-resistant automobile rubber hose is prepared from raw materials in parts by weight as follows: 6-14 parts of blast furnace slag micro-powder, 4-9 parts of fast extruding furnace black N550, 3-9 parts of carnauba wax, 4-7 parts of a friction property modifier, 2-6 parts of aluminum oxide, 3-6 parts of graphite, 4-9 parts of acetyl triethyl citrate, 1-3 parts of black soil, 3-9 parts of talc powder, 1-5 parts of a coupling agent, 4-9 parts of polyolefin elastomers, 3-6 parts of polypropylene resin, 4-10 parts of poly(4-methyl-1-pentene) and 6-14 parts of vinyl trimethoxy silane. The automobile rubber hose has the benefits as follows: the wear-resistant automobile rubber hose has good wear resistance and acid and alkali resistance, is long in service life and well guarantees the normal work of an automobile.

Description

technical field [0001] The invention relates to a wear-resistant rubber hose for automobiles. Background technique [0002] Rubber hoses are mainly used to connect the engine and air filter, engine and radiator system, automotive air conditioning system, etc. At present, automobile rubber hoses use heat-shrinkable sleeves, which are in a tubular structure. At present, nitrile rubber is used as the fuel pipe, and nitrile rubber is not suitable for the fuel system, most of which contain halogen and have poor flame retardancy. Therefore, the use needs of automobiles cannot be well satisfied, causing the safety of automobiles to be unguaranteed; meanwhile, with the development of society, people have higher and higher requirements for rubber hoses. Therefore, high-performance rubber hose is a direction that people are pursuing. Contents of the invention [0003] In view of the deficiencies in the prior art, the problem to be solved by the present invention is to provide a w...
