Technical Field
The invention relates to the technical field of automobile antifreeze, and in particular belongs to antifreeze with anti-scaling capability.
Background
The automobile coolant is also called antifreeze, and has an antifreeze function. The antifreeze fluid can prevent the coolant from freezing to crack the radiator and freeze the engine block or head when the vehicle is parked in cold winter. Therefore, the coolant is required to have an anti-freezing ability, and furthermore, since the anti-freezing fluid flows in a pipe when in use and is used to transfer heat, the anti-freezing fluid is also required to have an anti-scaling ability while not being capable of corroding an engine and a radiator of an automobile.
Disclosure of Invention
The invention aims to provide an antifreezing solution with anti-scaling capability, which overcomes the defects of the prior art, has the anti-scaling capability, and has lower melting point and lower corrosion performance on metal.
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 emulsifying agent and 70-80 parts of water.
Wherein, the composition also comprises 1-2 parts by weight of water-soluble rare earth complex.
Wherein the water-soluble rare earth complex is dinonyl phenol polyoxyethylene ether cerium phosphate.
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 anti-fouling performance of the automobile anti-freezing solution is greatly improved after the isopropyl acetate and the emulsifier are added.
2. According to the invention, the water-soluble rare earth is added for matching, so that the automobile antifreeze fluid has electron annihilation capability, and the oxidation resistance of the antifreeze fluid and the corrosion protection effect on metals are effectively improved.
3. The antifreeze fluid has the advantages of freezing resistance, good durability, less corrosiveness to metal during use and better than the existing antifreeze fluid.
