Quick anti-crack cooling fluid for metal tube welding positions and preparation method of cooling fluid

Abstract

The invention relates to a quick anti-crack cooling fluid for metal tube welding positions and a preparation method of the cooling fluid. The 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 butyl acrylate, 60-65 parts of methylcellulose, 10-13 parts of hydroquinone, 5-6 parts of acrylic acid, 5-6 parts of ethyl cyanoacetate, 5-6 parts of solid formaldehyde, 6-9 parts of vinyl acetate, 8-11 parts of tricresyl phosphate, 30-40 parts of dibutyl maleate, 40-50 parts of naphthenic base oil, 2-5 parts of an anti-wear agent, 5-10 parts of an anti-corrosion and antirust agent, 2-5 parts of a cleaning factor, 5-15 parts of propolis, 1-3 parts of a metal deactivator and 8-12 parts of a viscosity modifier. The preparation method is simple, the adhesive in the cooling fluid and base oil are bonded in high-temperature welding positions, cracking is avoided, meanwhile, little equipment is used, energy consumption is low, the production cost is low, and the product is very popular among customers, 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 an anti-collapse rapid cooling liquid for metal pipe welding 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 stil...

Problems solved by technology

[0003] After the existing metal pipes are welded, most of the welds are cooled by natural cooling. In order to speed up the cooling rate, water is sprayed, one cold and one hot, which will easily cause the welds to crack
