Abstract

The present invention discloses a propylene glycol anhydrous type coolant, which comprises the following raw materials by weight: 100 parts of 1,2-propylene glycol, 0.1-0.5 part of methyl benzotriazole, 0. 5-1.5 parts of polyaminoacid, 0.1-0.5 part of diethylenetriamine pentaacetic acid iron-sodium complex, 0.5-1.5 parts of sodium benzoate and 0.1-0.3 part of dimethicone. The propylene glycol anhydrous type coolant provided by the present invention has high stability, overcomes the technical defect of easy boiling of the traditional aqueous coolant, and helps the operation of engine at full load and high load.

Description

technical field [0001] The invention relates to a cooling liquid, in particular to a propylene glycol anhydrous cooling liquid. Background technique [0002] The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and bursting the radiator and freezing the engine cylinder block or cover when the vehicle is parked in cold winter. But we have to correct a misunderstanding, antifreeze is not just for winter, it should be used throughout the year. In the normal maintenance items of the car, the engine antifreeze needs to be replaced every year of driving. [0003] Coolant is mainly used in the cooling system of automobile engine, which has the functions of cooling, antifreezing, anti-scaling, anti-corrosion, and anti-boiling. The coolant is mainly composed of antifreeze, water, corrosion inhibitor, defoamer, dyeing agent and so on. The key technology of the coolant is the ...
