Abstract

The invention aims to provide a novel automobile antifreeze which is prepared from the following components in parts by weight: 100 parts of water, 100-140 parts of propanediol, 0.1-0.3 part of corrosion inhibitor, 0.15-0.45 part of potassium permanganate, 0.1-0.5 part of antioxidant and 0.2-1.0 part of antiscale corrosion inhibitor. The novel automobile antifreeze has the advantages of high stability, high antifreezing property and high antiscale property, can not easily volatilize, and can not block pipelines.

Description

technical field [0001] The invention belongs to chemical preparations, in particular to antifreeze for automobile engines. Background technique [0002] With the improvement of people's living standards, automobiles are becoming more and more popular. Automobile antifreeze is generally composed of alcohols and added with related additives. It is a liquid with a low freezing point and will not freeze at low temperatures. , has good fluidity, can take away a large amount of heat generated during the operation of the engine, and ensure the normal operation of the engine equipment at low temperature. At present, the main components of antifreeze are methanol, ethylene glycol, and calcium chloride. Due to the low boiling point of methanol, calcium chloride is easy to precipitate, and these two types of materials have great potential safety hazards. [0003] The present invention is different from other antifreezing liquids, and is composed of propylene glycol, water, corrosion i...
