Stabilizer of long-acting anti-freezing solution

Abstract

The invention discloses a stabilizer of a long-acting anti-freezing solution. The stabilizer is prepared from, by mass, 25-30% of (3-Chloropropyl)trimethylsilane, 25-60% of organophosphorous phosphate, 0.1-1.5% of organic amine catalyst, 1.0-1.5% of tetrabutylammonium bromide or benzyl triethyl ammonium chloride, 3-5% of diatomaceous earth, 1-2% of potassium hydroxide, 1-2% of ethanediol, 0.1-1% of corrosion inhibitor, 0.1-1% of defoaming agent, 0.1-1% of dye and the balance deionized water. The organic amine catalyst is at least one of n-butylamine or N,N-dimethyl benzylamine. Organophosphorous phosphate is at least one of dimethylphosphoryl or diethyl phosphate. Organosilane type derivatives are added to the inorganic salt silicon type anti-freezing solution, and therefore it is well prevented that the stabilizer of the anti-freezing solution is produced according to the gelatinization tendency principle of silicate; meanwhile, a corrosion inhibitor is added to the stabilizer, and therefore the working time of the whole stabilizer is prolonged.

Description

technical field [0001] The invention relates to the field of antifreeze, in particular to a stabilizer for long-acting antifreeze. Background technique [0002] The full name of antifreeze is antifreeze coolant, which means coolant with antifreeze function. Antifreeze can prevent the coolant of power equipment from freezing in cold seasons and expand the radiator and freeze the engine cylinder block. In addition to antifreeze, antifreeze also has the following advantages: 1) Anti-corrosion function, the cooling system is made of metal, including copper, iron, aluminum, steel and solder. These metals will be corroded and rusted after a long time in contact with water at high temperatures. The antifreeze not only does not cause corrosion to the engine cooling system, but also has anti-corrosion and rust removal functions. 2) Anti-boiling function, the boiling point of water is 100°C, and the boiling point of high-quality antifreeze coolant is usually 110°C above zero, so it ...

3) Descaling function. The most troublesome problem when using water as a coolant is the scale problem. The scale adheres to the metal surface of the water tank and water jacket, making the heat dissipation effect worse and worse, and it is also very difficult to remove.

[0003] The widely used antifreeze has good anti-corrosion performance and cheap price, but the stability is not good

The main reason is that this antifreeze uses silicate as an anti-corrosion agent, and the silicate component has excellent aluminum alloy protection ability, but the silicate has a strong polymerization ability in an alkaline aqueous solution with a pH value of 7-9. , it is easy to produce silicate gel, which destroys the stability of antifreeze and has a great impact on the use of antifreeze
