Problems solved by technology

UV fire retardant coatings have disadvantages such as poor flame retardancy, poor film-forming properties, poor water resistance, oil resistance, and weather resistance, and after long-term ultraviolet radiation, the surface of the coating film will have an obvious tendency to change color, resulting in a decline in its mechanical properties.
Even if the use environment is indoors, the coating is damaged by diffuse sunlight or fluorescent radiation and eroded by chemical substances, resulting in yellowing and aging degradation of the coating film, which in turn leads to a decrease in the mechanical properties of the coating

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.

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 ...
