Embodiment 1

[0048] The first step, synthesis of halogenated epoxy acrylate X-EA

[0049] According to the molar ratio of halogenated epoxy resin epoxy group to acrylic acid of 1-1.05:1, add catalyst tertiary amine or quaternary ammonium salt and phenolic polymerization inhibitor, and react at 100-110°C for 3 hours , react at 118-125°C for 2 hours under temperature control, and detect the acid value < 3mgKOH / g to obtain X-EA.

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

[0051] The second step, synthesis of phosphate acrylate compound PA

[0052] Slowly add 1.1 moles of phosphorus pentoxid...

Embodiment 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 is 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, you can get X-EA

[0062] The second step, synthetic phosphate ester acrylate PA: phosphorus pentoxide in molar ratio: hydroxy chloroacrylate is 1: 1.1., phosphorus pentoxide is added in the hydroxypropyl chloroacrylate, stir while adding, control The temperature is ≤95°C. After the addition, the temperature is controlled at 85-110°C. After two hours, the halogenated propylene oxide is added. At 85-95°C, the reaction can be detected for 3 hours and the acid value reaches 5-8mgKOH / g. Stop the reaction;

[0063] The third step, by weight percentage, weighs 25% of halogenated epoxy acrylate X-EA, 20% of aliphatic polyurethane acrylat...

Embodiment 3

[0065] The first step is to synthesize halogenated epoxy acrylate, according to the molar ratio of halogenated epoxy resin epoxy group to acrylic acid is 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, you can get X-EA

[0066] The second step is to synthesize phosphate ester acrylate PA: the 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°C, after adding, control the temperature at 85-110°C, add halogenated propylene oxide two hours later, at 85-95°C, react for 3 hours and stop the reaction when the acid value reaches 5-8mgKOH / g;

[0067] The third step, by weight percentage, weighs 30% of halogenated epoxy acrylate X-EA, 10% of aliphatic polyurethane acrylate PUA, 7% of phosphate acrylate PA, and 7% of ...

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...
