Embodiment 1

[0023] 1. Preparation of flame-retardant modified fluorine-containing hyperbranched polyurethane-epoxy acrylic resin copolymer.

[0024] Step 1. Add 30g of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and 150mL of dioxane (AR) into a 250mL four-necked flask, blow nitrogen gas and Stir and heat up to 90°C, after DOPO is completely dissolved, start to drop 15g of HOCH 2 CF 2 O(CF 2 CF 2 O) 15 (CF 2 O) 15 CF 2 CH 2 OH perfluoropolyether diol (ZDOL) with stirring, the ZDOL dropping speed is 0.8mL / min, and the stirring speed is 300r / min. After the dropping is completed, the temperature is raised to 80°C, and the reactant is rotated for 1 hour to recover the dioxygen. Hexacyclic, the viscous product was obtained after the reaction, and then washed 5 times with absolute ethanol, and vacuum-dried at 70°C for 7 hours to obtain the modified flame retardant DOPO-ZDOL; for the synthesis mechanism diagram of DOPO-ZDOL, see figure 1 .

Embodiment 2

[0030] 1. Preparation of flame-retardant modified fluorine-containing hyperbranched polyurethane-epoxy acrylic resin copolymer:

[0031] Step 1. Add 20g of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and 100 mL of dioxane (AR) into a 250ml four-necked bottle, and blow nitrogen Stir and heat up to 90°C, after DOPO is completely dissolved, start to drop 13g of HOCH 2 CF 2 O(CF 2 CF 2 O) 13 (CF 2 O) 10 CF 2 CH 2OH perfluoropolyether diol (ZDOL) with stirring, the ZDOL dropping speed is 0.5mL / min, and the stirring speed is 300r / min. After the dropwise addition is completed, the temperature is raised to 80°C, and the reactant is rotated for 1 hour to recover the dioxygen. Hexacyclic, a viscous product was obtained after the reaction, and then washed 5 times with absolute ethanol, and vacuum-dried at 70°C for 10 hours to obtain the modified flame retardant DOPO-ZDOL.

[0032] Step 2. In a 500ml three-necked flask, add 250mL of acetone solution of H302 hydroxy...

Embodiment 3

[0037] 1. Preparation of flame-retardant modified fluorine-containing hyperbranched polyurethane-epoxy acrylate resin copolymer:

[0038] Step 1. Add 25g of H302 hydroxyl-terminated hyperbranched polyester (purchased from Wuhan Hyperbranched Resin Technology Co., Ltd.) (DOPO) and 150 mL of dioxane (AR) into a 250mL four-necked bottle, blow in nitrogen and stir to raise the temperature to 90°C, after DOPO is completely dissolved, start to drop 20g of HOCH 2 CF 2 O(CF 2 CF 2 O) 10 (CF 2 O) 12 CF 2 CH 2 OH perfluoropolyether diol (ZDOL) with stirring, the ZDOL dropping speed is 0.8mL / min, and the stirring speed is 400r / min. After the dropwise addition is completed, the temperature is raised to 85°C, and the reactant is rotated for 1 hour to recover the dioxygen. Six rings, a viscous product was obtained after the reaction, and then washed with absolute ethanol for 5 times, and vacuum-dried at 60°C for 10 hours to obtain the modified flame retardant DOPO-ZDOL.

Abstract

The invention belongs to the field of coating and particularly relates to UV (ultraviolet) fire retardant coating and a preparation method thereof. The UV fire retardant coating comprises the following raw materials in parts by weight: 30-40 parts of 1, 6-ethylene glycol diacrylate, 30-40 parts of flame retardant modified hyperbranched acrylic resin, 15-20 parts of polyesteracrylate, 0.5-2 parts of a photoinitiator, 1-3 parts of an adhesion promoter and 0.5-1 part of a flatting agent. The coating is excellent in flame retardant property and comparatively strong in weather resistance and belongs to environment-friendly coating.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a UV fireproof coating and a preparation method thereof. Background technique [0002] Traditional fireproof coatings are volatile and slow in curing, which is not conducive to environmental protection; while UV fireproof coatings have the advantages of low environmental pollution, fast curing speed, energy saving, good performance of cured products, and suitable for high-speed automatic production; therefore, UV fireproof coatings are A major alternative to traditional fire retardant coatings. [0003] Traditional UV fire retardant coatings are generally composed of monomers, reactive diluents, flame retardants, photoinitiators and various additives. They are environmentally friendly and energy-saving fire retardant coatings characterized by radiation curing technology. UV fire retardant coatings have disadvantages such as poor flame retardancy, poor film-forming properties, poor water ...
