| titleOfInvention | A kind of preparation method of the aqueous polyester resin for coil coating and application thereof |
| abstract | A kind of preparation method of the aqueous polyester resin for coil coating and application thereof, described preparation method comprise the steps: (1) with a certain amount of alcohol with band carboxyl hydrophilic monomer under the effect of catalyzer, in 170 ~ 240 DEG C of temperature prepolymerizations 1 ~ 5 hour, OH/COOH ratio was 2 ~ 20; (2) acid number adds other alcohol and sour starting material after being less than 3mgKOH/g, slowly heats up, and is incubated 3 ~ 8 hours at 180 DEG C ~ 230 DEG C temperature; (3), after acid number is less than 90mgKOH/g, takes micromolecular water out of with the varsol backflow of 5 ~ 30wt%, at 180 ~ 250 DEG C of temperature, be incubated 5 hours; (4) be cooled to less than 150 DEG C, add the small molecule monomer of band epoxide group, acid number stops heating after being less than 2mgKOH/g; (5) add hydrophilic solvent, water, obtain aqueous polyester resin.The aqueous polyester resin obtained is combined with linked and base-material of painting, and is applicable to the aqueous finish paint manufacturing low VOC, for metal coiled material. |
