In order to solve the problems, the technical scheme adopted by the invention is as follows:
an antifreezing solution with anti-scaling capability comprises the following raw materials in parts by weight: 20-30 parts of 1, 3-propylene glycol, 5-10 parts of isopropenyl acetate, 2-5 parts of an emulsifier and 70-80 parts of water.
Wherein, the water-soluble rare earth complex also comprises 1 to 2 weight portions.
Wherein the water-soluble rare earth complex is cerium phosphate polyoxyethylene dinonylphenol.
Wherein the emulsifier is one of OP-10, Tween 80 or sorbitan monooleate.
Compared with the prior art, the invention has the following implementation effects:
1. the automobile antifreeze fluid disclosed by the invention is used by mixing propylene glycol and water with isopropenyl acetate, the melting point of the antifreeze fluid is effectively reduced to be as low as-52 ℃, and the anti-scaling performance of the automobile antifreeze fluid is greatly improved after the isopropenyl acetate and the emulsifier are added.
2. According to the invention, by adding the water-soluble rare earth for matching, the automobile antifreeze has the capability of electron annihilation, and the oxidation resistance and the corrosion protection effect on metals of the antifreeze are effectively improved.
3. The antifreeze fluid has the advantages of frost resistance, good durability and less corrosion to metals when in use, and is superior to the existing antifreeze fluid.
