Abstract
A methanol gasoline rubber swelling inhibitor is prepared from the following ingredients in parts by weight: 12 parts of 2-mercaptobenzothiazole, 8 parts of iodopropynyl butylcarbamate, 1 part of butylated hydroxyanisole, 16 parts of 2,6-butylated hydroxytoluene, 8 parts of sodium dodecyl sulfonate, 13 parts of 2-ethylimidazole, 6 parts of dichloro[(1,2,5,6-eta)-cycloocta-1,5-diene]ruthenium, 9 parts of methoxypropiophenone, 2 parts of polyisobutylene succinimide, 3 parts of tert-butyldimethylsilyl chloride and 12 parts of methyl tert-butyl ether. The methanol gasoline rubber swelling inhibitor is used by the method that the methanol gasoline rubber swelling inhibitor is directly added into methanol gasoline M15-M30 and mixed uniformly, and the adding quantity is 0.4-0.7% of the weight of the methanol gasoline. The methanol gasoline rubber swelling inhibitor has excellent oxidation resistance and excellent corrosion resistance, and can prevent related seal parts of a vehicle from being worn or corroded, keep the elasticity of rubber components and prevent rubber aging.
Description
Technical field [0001] The invention relates to a fuel oil additive for vehicles, in particular to a methanol gasoline rubber swelling inhibitor. Background technique [0002] Methanol gasoline refers to a new type of environmentally friendly fuel methanol and gasoline mixture that is formulated by a strict process with a certain volume (mass) ratio of national standard gasoline (93#, 97#, etc.), methanol, and additives. It also includes mixtures of methanol, ethanol, n-propanol, n-butanol and isopropanol, and gasoline. [0003] The amount of methanol incorporated is generally 5% to 30%. With 15% blending as the most, it is called M15 methanol gasoline. The anti-knock performance is good, the research octane number (RON) increases with the increase of the amount of methanol added, and the motor octane number (MON) is not affected. Combustion emissions are less toxic than ordinary leaded gasoline, and the exhaust gas contains less carbon monoxide. Good combustion cleaning perfor...
