Invention name: a high-gloss high-level powder coating with epoxy curing polyester resin and its preparation method

China Coatings Online News Information: The present invention relates to a polyester resin and its preparation method for a high-gloss high-level powder coating with epoxy curing. The aim is to provide polyester resins with a higher glass transition temperature. The technical scheme is: a high-gloss high-level powder coating with polyester resin, including the following parts are: neo-glycol, 2-methyl propylene glycol, glycol, 2-butyl-2-ethyl-1, 3-propylene glycol, parabens, methyl xylene, methyl glycerides. A preparation method of polyester resin for high-gloss high-level powder coating with epoxy curing, according to the following steps: 1) in the reactor, add the ratio of polyols, normal pressure heating, and then put the ratio of polyic acid and esterification catalyst; 2) the insulation reaction to the esterified water out of 95% and above of the theoretical water flow; 3) add partial benzoic acid, interbenzene acid; insulation reaction; 4) gradually vacuum, continue to react; 5) feed.
