Example Embodiment
[0052] The preparation method of the bromine-carbon-containing polyester powder fireproof coating of the present invention is prepared according to the above formula, and the preparation steps are:
[0053] a. Mix the epoxy resin E-12 and the liquid leveling agent at high speed for 3 to 5 minutes to obtain the loaded liquid leveling agent;
[0054] b. Mix the carboxyl-terminated bromocarbon polyester resin, solid leveling agent and loaded liquid leveling agent, add curing agent, dicyandiamide, titanium dioxide, precipitated barium sulfate, zinc oxide, light calcium carbonate, zinc acetate, Antimony trioxide, molybdenum trioxide and zinc borate are mixed;
[0055] c. Put the above mixture into the extruder to melt and extrude to obtain the molten material. The temperature of the feeding section is 85-95℃, the temperature of the melting section is 95-105℃, the temperature of the mixing section is 105-120℃, and the temperature of the discharging section 100~110℃; The average residenc...
Example Embodiment
[0063] Example 1:
[0064] This embodiment is a preparation method of the carboxyl-terminated bromocarbon polyester resin of the present invention.
[0065]a. Add 2000g of dimethyl terephthalate, 950g of ethylene glycol, 750g of neopentyl glycol and 5g of zinc acetate into a reaction flask with a fractionating column, stirring, thermometer and inert gas inlet, and slowly heat to melt the material. After melting, start stirring, pass inert gas, and react at 150°C to 210°C until 800ml of methanol is removed.
[0066] b. Slowly increase the temperature to 230°C to remove 400ml of ethylene glycol, add 750g of tetrabromophthalic anhydride and 140g of adipic acid, and increase the temperature to 240°C for esterification reaction and dehydration of 125ml.
[0067] c. Stop passing inert gas, add 5g antimony trioxide, control the temperature of reduced compression polymerization below 240℃, vacuum 15mmHg, react for 1.5h, take a sample and measure the softening point at 110℃.
