Abstract

The invention discloses an anticorrosion and environmental protection automobile antifreeze fluid, which belongs to the technical field of the antifreeze fluid. The automobile antifreeze fluid comprises the following components by weight: 80-90 parts of glycol, 10-30 parts of deionized water, 10-20 parts of corrosion inhibitor, 5-10 parts of silicate, 6-8 parts of silicate stabilizing agent, 1-3 parts of antifoaming agent and 1-5 parts of colouring agent. The invention also discloses a preparation method of the antifreeze fluid. The automobile antifreeze fluid employs nontoxic silicate as an auxiliary agent of the corrosion inhibitor, addition of the silicate stabilizing agent can provide long-acting anticorrosion, and the silicate stabilizing agent has the advantages of low price, environmental protection, no pollution, and no gel deposition and fouling generation; the preparation method of the automobile antifreeze fluid has the advantages of simple process, environmental protection and easy implement.

Description

technical field [0001] The invention belongs to the technical field of antifreeze, and in particular relates to an anti-corrosion and environment-friendly automobile antifreeze and a preparation method thereof. Background technique [0002] The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze is the cooling medium of the internal combustion engine circulation cooling system, and the working state of the cooling system directly affects the normal operation of the vehicle and the service life of the vehicle. Antifreeze Not just for winter, it should be used year-round. Traditional antifreeze is mainly composed of antifreeze and additives, which not only has high production cost, but also has poor anti-corrosion performance and serious process pollution. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to provide anti-corrosion and environmental protection...
