Environment-friendly type long-acting automobile cooling liquid formulation and producing technique thereof

Abstract

The invention discloses a formula of environmental friendly type long-term automobile coolant and a process for preparation, the formulation contains glycol, desalting water, decanedioic acid, sodium benzoate, sodium molybdate, borax, polybenzotriazole, sodium metasilicate, sodium hydroxide, metasilicate, stabilizing agent, defoaming agent and coloring agent, catalyst cases A, B and C are adopted to mix and react under normal temperature and normal pressure, the pH value of the coolant which is generated is controlled within 8-9, the automobile coolant of the invention has the efficiencies of anti-freeze, anti-boiling, anti-corrosion, anti-fouling and can diffuse heat fast, the cooling effect is good, the necessary raw materials can be easily bought on the market, the coolant has non hazardous substances such as sodium nitrite and the like, lowers the harm to environment and human bodies, generates non gelatin during storing periods, can not dilute any inhibitor, and has long-term performance, the manufacturing process of the product is simple, the using equipment is less, the operation is easy, the demanding energy consumption is low, the producing cost is low, the coolant is easy for industrial-scale production and has high promotion and application value and good market prospects.

Description

technical field [0001] The invention relates to a formula and a production process of cooling liquid used in an automobile engine cooling system. technical background [0002] When the automobile engine is working, the temperature of the cylinder is very high. If the cylinder is overheated, a series of adverse consequences will be produced. Therefore, the car engine must be cooled during the working process. There are roughly two cooling methods, one is air cooling, and the other is liquid cooling, which is used by most car engines. Liquid cooling, initially uses water as the medium At present, ethylene glycol and water are mostly used as the medium for cooling. [0003] Ethylene glycol coolant has been used in automotive engine coolant systems abroad since the 1920s and 1930s, and it has been gradually used in civilian vehicles in my country since the early 1980s. [0004] Ethylene glycol coolant can be divided into inorganic salt type, organic acid type, organic acid and...

Problems solved by technology

[0006] Organic acid type coolant, the anti-corrosion process is to form a protective film with metal adsorption, so the consumption is slow, the product life cycle is longer, and its anti-corrosion performance is better, but its foam tendency is serious, the foam tendency is not well controlled, and cavitation occurs Potential for corrosion and high production costs
