Rubber swelling inhibitor

Abstract

The invention relates to a rubber swelling inhibitor, which is used for inhibiting the swelling of the ordinary rubber and solves the technical problem of the swelling of rubber pieces of an automobile oil supply system, which is caused by methanol gasoline. The rubber swelling inhibitor is prepared from the following raw materials in part by weight: 4 to 18 parts of 2,6-dimethyl morpholine, 6 to 21 parts of tris(2-chloroethyl) phosphate, 0 to 5 parts of N-ethyl morpholine, 6 to 26 parts of dicumyl peroxide, 3 to 21 parts of 2,4,6-trichloro-phenyl isocyanate, 10 to 40 parts of No.120 solvent gasoline, 3 to 12 parts of sodium dibutyl dithiocarbamate, 2 to 9 parts of bis(N,N-diamyl dithiocarbamate)zinc, 5 to 11 parts of stearic acid, 8 to 23 parts of bis(2-ethylhexyl) phthalate, 7 to 17 parts of hexyl alcohol and 0 to 7 parts of butyl acetate. The rubber swelling inhibitor is appropriate in cost, and easy to produce, can inhibit the swelling of the ordinary rubber by the methanol gasoline effectively, and also has a certain corrosion-inhibiting and protective effect on metal parts of an engine. In addition, pollution discharge of tail gas of vehicles is reduced, and the discharge of major pollutants is far below the national standard.

Description

technical field [0001] The invention relates to an inhibitor for anti-rubber swelling, in particular to an inhibitor for making ordinary oil-resistant rubber possess the performance of methanol-gasoline resistance. Background technique [0002] With the increasing shortage of world oil resources and the increasing air pollution, the energy crisis has become the bottleneck of economic development, and new alternative fuels have attracted the attention of all parties. my country's dependence on foreign oil has exceeded 53%, and energy and environmental issues restrict the rapid development of my country's economy. my country is a country that is poor in oil and gas but relatively rich in coal. It is completely feasible to use coal to produce methanol to replace part of the oil. Using methanol as an alternative fuel for internal combustion engines is an effective way to protect the environment and use energy rationally. [0003] However, compared with the national standard gas...
