Rapid cooling fluid for metal tube cutting surfaces and preparation method of rapid cooling fluid

Abstract

The invention discloses a rapid cooling fluid for metal tube cutting surfaces and a preparation method of the rapid cooling fluid. The rapid cooling fluid is prepared from raw materials in parts by weight as follows: 150-200 parts of soybeans, 10-15 parts of a modified amine and polyamide mixture, 20-25 parts of titanium dioxide, 60-65 parts of polyether urethane, 10-13 parts of ammonium persulfate, 5-6 parts of acrylic acid, 5-6 parts of caustic soda, 5-6 parts of ammonium hydroxide, 6-9 parts of vinyl acetate, 8-11 parts of liquid low-molecular-weight polyamide, 30-40 parts of epoxy chloropropane, 40-50 parts of naphthenic base oil, 2-5 parts of an anti-wear agent, 5-10 parts of an anti-corrosion and anti-rust agent, 2-5 parts of a cleaning factor, 5-15 parts of propolis, 1-3 parts of metal deactivator and 8-12 parts of a m-cresol curing accelerator. The preparation method is simple, the adhesive and base oil in the cooling fluid are bonded in high-temperature welding positions, cracking is avoided, little equipment is used, energy consumption is low, the production cost is low, and the cooling fluid is very popular among clients, has very high popularization and application value and has bright market prospects.

Description

Technical field: [0001] The invention relates to the field of chemical industry, in particular to a rapid cooling liquid for cutting surfaces of metal pipes and a preparation method thereof. Background technique: [0002] The coolant is composed of water, antifreeze, and additives. According to the composition of the antifreeze, it can be divided into alcohol type, glycerin type, and ethylene glycol type. Alcohol-type coolant uses ethanol (commonly known as alcohol) as antifreeze, which is cheap, has good fluidity, and has a simple preparation process, but has a low boiling point, easy evaporation loss, easy increase in freezing point, and flammability, etc., and has been gradually eliminated; Glycerin-type coolant has a high boiling point, low volatility, is not easy to catch fire, is non-toxic, and is less corrosive, but it has poor freezing point reduction effect, high cost, and high price. It is difficult for users to accept it, and only a few Nordic countries are still ...
