Abstract

The invention provides a water-resistant composite additive for vehicular fuel oil. The water-resistant composite additive is prepared from the following components in percentage by weight: 40-70% of mutual solvent, 20-40% of oxidization-corrosion inhibitor, 2-6% of bactericide and 8-14% of auxiliaries; the mutual solvent comprises the following components in percentage by weight: 10-30% of methyl tert-butyl ether, 10-15% of tert-butyl acetate, 15-20% of dimethyl carbonate, 40-50% of a mixture of C3-C6 higher alcohols, and 5% of N-ethylpyrrolidine; the oxidization-corrosion inhibitor comprises the following components in percentage by weight: 30-50% of 2,6-tert-butyl phenol, 10-15% of Bis(1-methylpropyl)-1,4-phenylenediamine, 20-30% of T1201, 15-20% of methyl benzotriazole and 5% of a mixture of ethoxylated alkylphenol and oil-soluble imidazolidine according to the weight ratio of 6:4; the bactericide comprises the following components in percentage by weight: 40-60% of dioxolakylborane-containing solution, 15-30% of N-benzylideneaniline, 10-15% of polyethylene glycol borate, and 15% of 2-methyl-4-Isothiazolin-3-one; and the auxiliaries comprise the following components toluene, aviation kerosene, dioctyl sebacate and cyclohexane according to the weight ratio of 3:2:1:4. The water-resistant composite additive can effectively solve the problems that the vehicular fuel oil causes phase separation, serious corrosion and wear to an engine, and the like when absorbing water during production and storage and transportation.

Description

technical field [0001] The invention relates to a fuel additive, in particular to a water-resistant composite additive for vehicle fuel oil and its application. Background technique [0002] Based on the requirements of optimizing energy structure and environmental protection, promoting and using motor gasoline, ethanol gasoline, and methanol gasoline at the same time is one of the important measures to alleviate my country's energy "bottleneck" and realize energy diversification and sustainable development strategic planning. [0003] Moisture in automotive fuel oil refers to the total amount of water in various phases such as free water, emulsified water, and dissolved water in the oil. According to the national standard GB 17930-2011 / XG1-2012 "Automobile Gasoline" Phase IV standard moisture (mass fraction) technical requirements are none; GB 18351-2010 "Automotive Ethanol Gasoline (E10)" standard moisture (mass fraction) ) technical requirement is not more than 0.2%; GB / ...
