Problems solved by technology

[0002] According to the data released by the Traffic Management Bureau of the Ministry of Public Security, as of the end of 2014, the number of motor vehicles in my country reached 264 million, and the pollution of the environment by motor vehicles is becoming more and more serious. Among them, motor vehicles need to replace the antifreeze coolant every two or three years. 6 kg of antifreeze coolant needs to be replaced, and 528,000 tons of antifreeze coolant needs to be replaced every year; at present, the antifreeze coolant sold on the market is ethylene glycol type, which itself cannot be biodegraded. Most of the vehicles are directly discharged after replacement, seriously polluting groundwater sources , which is very harmful to the environment, so it is imminent to solve the problem of vehicle exhaust coolant pollution

Abstract

The invention belongs to the technical field of chemical production, and is named environment-friendly automobile antifreezing coolant and puctirodon method. The method includes the following steps: (b) according to percentages by weight, 5 to 70 percent of first main material, sodium benzoate, EDTA (ethylene diamine tetraacetic acid), deoxidated sodium acetate, potassium sorbate, sodium hydroxide and the balance of purified water are adopted, and the sum of the contents of all the components in the formula is 100 percent; herein, the first main material is one of glycerin, sorbitol and glucose or the mixture of two or three of glycerin, sorbitol and glucose; (b) the first main material and the purified water are added into a reaction kettle, agitated and heated, the rest materials are added after uniform mixing, the reaction kettle is closed, the temperature of the reaction kettle is decreased to room temperature after electric heating and continued agitation, and thereby the environment-friendly automobile antifreezing coolant is produced. The environment-friendly automobile antifreezing coolant produced by such a production method for the environment-friendly automobile antifreezing coolant can degrade after being discharged, and does not pollute the environment and underground water; such environment-friendly automobile antifreezing coolant can degrade after being discharged, and does not pollute the environment and underground water.
