Example Embodiment

[0047] Example 1

[0048] The first step is to synthesize halogenated epoxy acrylate X-EA

[0049] Add the catalyst tertiary amine or quaternary amine salt and phenol polymerization inhibitor at the molar ratio of halogenated epoxy resin epoxy group to acrylic acid in the ratio of 1~1.05:1, and react at 100~110℃ for 3 hours , And react at 118~125℃ for 2 hours, check the acid value<3mgKOH / g, then X-EA can be obtained.

[0050] The halogenated epoxy resin can be replaced by chlorine and bromine, and bromine is generally more effective. The tertiary amine or quaternary ammonium salt of the catalyst is any one of triethylamine or tetraethylammonium bromide, and the amount is 0.1-0.3% of the mass of acrylic acid. The phenol polymerization inhibitor is hydroquinone or p-hydroxyanisole, and the amount is 0.05-0.1% of the mass of acrylic acid.

[0051] The second step is to synthesize phosphate acrylate compound PA

[0052] Use 1.1 moles of phosphorus pentoxide to slowly add 1.5 moles of hyd...

[0060] Example 2

[0061] The first step is to synthesize halogenated epoxy acrylate. According to the molar ratio of halogenated epoxy resin epoxy group to acrylic acid of 1.05:1, add catalyst and polymerization inhibitor, and control the temperature at 100-110°C for 3 hours , Control the temperature at 118-125 degrees for 2 hours, and detect the acid value <3mgKOH / g, then X-EA can be obtained

[0062] The second step is to synthesize phosphate acrylate PA: molar ratio of phosphorus pentoxide: hydroxy chloroacrylate is 1:1.1. Add phosphorus pentoxide to hydroxypropyl chloroacrylate, stir while adding, and control Temperature ≤95℃, after the addition, control the temperature at 85-110℃, add halogenated propylene oxide after two hours, and stop the reaction when the acid value reaches 5-8mgKOH / g after 3 hours of reaction at 85-95℃;

[0063] The third step is to weigh the halogenated epoxy acrylate X-EA as 25%, the aliphatic urethane acrylate PUA as 20%, the phosphate acrylate PA as 5...

[0065] The first step is to synthesize halogenated epoxy acrylate. According to the molar ratio of halogenated epoxy resin epoxy group to acrylic acid of 1.05:1, add catalyst and polymerization inhibitor, and control the temperature at 100-110°C for 3 hours , Control the temperature at 118-125 degrees for 2 hours, and detect the acid value <3mgKOH / g, then X-EA can be obtained

[0066] The second step is to synthesize phosphate acrylate PA: molar ratio of phosphorus pentoxide: hydroxy chloroacrylate is 1:1.2. Add phosphorus pentoxide to hydroxy chloroacrylate, stir while adding, and control the temperature ≤95℃, control the temperature at 85-110℃ after adding, add halogenated propylene oxide after two hours, and stop the reaction when the acid value reaches 5-8mgKOH / g after 3 hours of reaction at 85-95℃;

[0067] The third step is to weigh the halogenated epoxy acrylate X-EA as 30%, the aliphatic polyurethane acrylate PUA as 10%, the phosphate acrylate PA as 7%, an...

Abstract

The invention provides an ultraviolet cured flame-retardant coating and a preparation method thereof. The components by weight percent are as follows: 25-35 percent of halogenated epoxy acrylate; 10-15 percent of aliphatic polyurethane acrylate; 5-10 percent of phosphate-acrylate; 10-15 percent of halogenated acrylate; 10-28 percent of TMPTA; 5-6 percent of photoinitiator; 10-20 percent of inorganic flame retardant agent; and 3-5 percent of additives. The preparation method is as follows: synthesizing the halogenated epoxy acrylate and the phosphate-acrylate; then weighing the halogenated epoxy acrylate, the aliphatic polyurethane acrylate, the phosphate-acrylate, the halogenated acrylate monomer, the TMPTA, the photoinitiator, the inorganic flame retardant agent and the additives; and stirring to mixing the PA, the epoxy acrylate X-EA and the aliphatic polyurethane acrylate PUA, adding the XA monomer, the TMPTA monomer and the additives such as dispersing agent and defoamer after mixing thoroughly, dispersing at the speed of 900-1200r/min, adding a flame retardant agent, a leveling agent and other residual additives and the photoinitiator after dispersing thoroughly, and then dispersing for 30 minutes at the high speed of 1200-1500r/min.

Description

technical field [0001] The invention belongs to the field of preparation of ultraviolet light flame retardant coatings, in particular to a preparation method of ultraviolet light curing flame retardant coatings. Background technique [0002] UV-curable coating is an environmentally friendly and green coating developed in the middle of the 20th century. It has been developed and produced in China for less than 20 years. Because of its environmental protection, energy saving and high efficiency, it is a kind of green building decoration and protection material that China and the world are pushing. In the past eight years, it has been developing at a rate of 25% in my country. Ultraviolet light is gradually applied to many fields due to its environmental protection, high efficiency and special properties. [0003] Resins cured by ultraviolet light cross-linking have gradually replaced traditional heat-initiated polymerization coatings or adhesives, but the main defect of this...
