Abstract

The invention discloses a composite automobile antifreezing solution which is characterized by consisting of the following components in parts by weight: 10-20 parts of glycerol, 0.1-0.5 part of sodium molybdate, 10-15 parts of sodium benzoate, 0.1-0.5 part of potassium nitrate, 0.01-0.05 part of a silicate stabilizer, 5-12 parts of sebacic acid, 5-10 parts of a cationic surfactant, 5-10 parts of pentaerythritol and 10-20 parts of deionized water. A formula systems free of phosphate radical is adopted, molybdate is adopted in the formula to work together with organic acid to protect metals, and due to adoption of potassium nitrate, long-term durable metal corrosion resistance can be provided, and due to use of lots of sebacic acid in the formula, the metal corrosion resistance is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of antifreeze, in particular to a compound antifreeze for automobiles. Background technique [0002] According to the evaluation of the impact on the environment, the types of antifreeze can be divided into environmentally friendly pure organic acid antifreeze and low-grade inorganic salt antifreeze. Pure organic acid antifreeze is environmentally friendly and easy to biodegrade, but the cost of use is relatively high. Expensive, so it has not been widely promoted in our country. In recent years, with the development of my country's automobile industry, the antifreeze system has gradually converged to the pure organic acid formula. There have been a large number of compound organic acid formula technologies containing phosphorus and adding some inorganic salts in the market. However, for the market, especially in Europe and the United States As far as the market is concerned, the use of phosphorus-containing...
