Problems solved by technology

[0003] In order to overcome the defect that the existing high-speed rail windshield paint is not flame-retardant; or although it has a flame-retardant function, the rubber windshield is stretched and deformed, causing the paint to fall off due to fatigue and aging, and cannot guarantee the long-term protection of the rubber windshield. The invention provides a A flame-retardant polyacrylate resin with flame-retardant self-extinguishing function and the same high elasticity as rubber; its raw material sources are sufficient and wide, the operation process is simple and safe, and it can meet the high elasticity required for the use of high-performance rubber fire-resistant coatings Polyacrylate flame retardant resin and preparation method thereof

Embodiment 1

[0027] In a four-neck flask equipped with a condenser, a dropping device, a stirrer, and a thermometer, add 270.0 grams of xylene, and raise the temperature to 130-150°C; then start to drop 0.72 grams of di-tert-butyl peroxide, 135.2 grams of hydroxyethyl methacrylate phosphate, 95.3 grams of methyl methacrylate, 5.07 grams of methacrylic acid, 0.55 grams of tert-12 mercaptan, and 30.9 grams of butyl methacrylate monomer mixture, 2.5-3 The hour dropwise addition was completed. The reaction was continued at 150° C. for 1 hour, and a solution of 0.51 g of di-tert-butyl peroxide (dissolved in 12.0 g of xylene) was added. After 1 hour, the temperature was lowered to 60° C., 30 grams of melamine cyanurate was added, filtered, the filter cake was taken, and dried to obtain a highly elastic polyacrylate resin.

Embodiment 2

[0029] Add 276.0 g of xylene to a four-necked flask equipped with a condenser, a dropping device, a stirrer, and a thermometer, and raise the temperature to 130-150°C. Then start to drop 0.90 grams of dicumyl peroxide, 132.0 grams of 2-hydroxyethyl methacrylate phosphate, 75.9 grams of methyl methacrylate, 6.8 grams of acrylic acid, and 0.58 grams of isooctyl 3-mercaptopropionate. , 56.0 grams of butyl acrylate, and 6.0 grams of methacrylic acid-β-hydroxyethyl ester monomer mixture solution, which was added dropwise in 2.5-3 hours. A solution of 0.65 g of dicumyl peroxide (dissolved in 12 g of xylene) was added, and the addition was completed dropwise within 1 hour, and the reaction was continued for 1 hour at 130-150° C. Cool down to 60° C. after 1 hour, add 28 grams of melamine cyanurate, and filter to obtain a highly elastic polyacrylate resin with flame-retardant and self-extinguishing function.

Embodiment 3

[0031] Add 256.0 g of xylene to a four-necked flask equipped with a condenser, a dropping device, a stirrer, and a thermometer, and raise the temperature to 130-150°C. Then began to drop 0.80 grams of dibenzoyl peroxide, 157.0 grams of 2-hydroxyethyl methacrylate phosphate, 60.0 grams of methyl methacrylate, 6.3 grams of methacrylic acid, 70.2 grams of butyl acrylate, dodecyl sulfide 0.63 grams of alcohol, 5.1 grams of isobornyl methacrylate monomer mixture, 2.5 to 3 hours to complete the addition. The reaction was continued at 150°C for 1 hour. Add 0.65 g of tert-butyl hydroperoxide (dissolved in 12 g of xylene) solution, cool down to 60° C. after 1 hour, and add 34 g of melamine cyanurate. After filtering, a highly elastic polyacrylate resin with flame-retardant and self-extinguishing function is obtained.

Abstract

The invention discloses a highly elastic polyacrylate resin and a preparation method thereof. The polyacrylate resin is composed of the following components in weight percent: solvent, ethylenically unsaturated phosphate monomer, acrylic acid and its ester monomers , initiator, chain transfer agent. The invention provides a highly elastic polyacrylate resin with flame-retardant self-extinguishing function and the same high elasticity as rubber; the source of raw materials is sufficient and wide, the operation process is simple, safe and can meet the high-performance fireproof coating for rubber.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a polyacrylate resin and a preparation method thereof. Background technique [0002] At present, the coatings widely used on high-speed rail windshields at home and abroad do not have fire protection function, or the method of adding flame retardants and other additives in ordinary resins is used to prepare coatings with fire protection function. This kind of coating either does not have the function of fire prevention; or although it has the function of fire prevention, the rubber windshield is stretched and deformed, which makes the coating fatigue and aging and falls off, which cannot guarantee the lasting protection of the rubber windshield. Contents of the invention [0003] In order to overcome the defect that the existing high-speed rail windshield paint is not flame-retardant; or although it has a flame-retardant function, the rubber windshield is stretched and deforme...
