Environmentally-friendly automobile engine coolant

Abstract

The invention discloses an environmentally-friendly automobile engine coolant which is prepared from the following raw materials in parts by weight: 30-70 parts of propylene glycol glucoside, 30-70 parts of water, 0.5-0.7 part of sodium hydroxide, 0.4-0.6 part of sodium nitrite, 0.5-0.7 part of sebacic acid and 0.2-0.4 part of benzotriazole. The novel environmentally-friendly automobile engine coolant, disclosed by the invention, is prepared by carrying out chemical reaction on starch and propylene glycol which are utilized as the raw materials in the presence of a catalyst (acid) at a certain temperature, using a generated product (propylene glycol glucoside) as a matrix of a deicing fluid, and preparing a small number of an antirusting agent, an antifouling composition and a foam suppressor. The environmentally-friendly automobile engine coolant adopts the propylene glycol glucoside for the deicing fluid; the propylene glycol glucoside has the advantages of no toxicity, harmlessness, good biodegradability and the like; the propylene glycol glucoside per se also has functions of sterilization and corrosion prevention; and the environmentally-friendly automobile engine coolant is completely environmentally-friendly.

Description

technical field [0001] The invention belongs to the technical field of automobile engine coolant, and in particular relates to a green and environment-friendly automobile engine coolant. Background technique [0002] The automotive engine coolants in the prior art are generally glycol-based, and with a small amount of additives, they have the functions of antifreezing, anti-boiling, anti-rust, anti-corrosion and anti-scaling, which can basically meet the working requirements of automotive engines. However, ethylene glycol has low toxicity to the human body, and it is dangerous to swallow a large amount, and ethylene glycol tastes sweet. Every year, there are reports of children eating car engine cooling by mistake. In addition, ethylene glycol is more serious to animals. Alcohol-type automobile engine coolant also has the problem that wastes are difficult to degrade in the environment. How to provide a non-toxic, harmless, and biodegradable automotive engine coolant has bec...
