Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0037] The specific implementation steps are as follows:

[0038] 1) Put polybasic acid, E10P, and polyalcohol into a 1L reaction flask equipped with a stirring device, a reflux condensing device, a dropping device and a temperature control device, feed in nitrogen, slowly heat to 190°C, keep it warm for 1 hour, and slowly raise the temperature to 250°C, keep warm for 6 hours, add 3% xylene in this step and reflux until the acid value is less than 20mgKOH / g, and control the temperature of the distillation head during the reaction to be less than 100°C;

[0039] 2) Cool down to 110°C and add co-solvent;

[0040] 3) Add a mixture of acry...

Abstract

The present invention relates to an aqueous acrylic acid modified saturated polyester resin, comprising the following materials of parts by weight: 5-25 parts of a polyacid, 15-40 parts of a polyol, 1-3 parts of a solubilizing agent, 5-20 parts of an acrylic acid monomer I, 0.5-10 parts of acrylic acid monomer II, 0.01-8 parts of an initiator, 0.5-10 parts of a neutralizer, 2-20 parts of glycidyl ester tertcarbonate, and 40-50 parts of deionized water. The aqueous acrylic acid modified saturated polyester resin prepared in the present invention has excellent stability, high solid-ness, low viscosity, and low VOC content, and can be mainly used for amino baked-on coating for aqueous coatings.

Description

technical field [0001] The invention relates to a preparation method of water-based acrylic acid modified saturated polyester resin, which belongs to the field of water-based coatings. Background technique [0002] Water-based coatings are more and more widely used as low-VOC content coatings. However, because of the low solid content of water-based coatings, it is difficult to achieve the high decorative effect of the soluble type. As the film-forming substance of water-based paint, water-based resin, the solid content, viscosity and VOC content of its aqueous dispersion play a decisive role in the performance of the paint film and the impact on the environment. Saturated polyester has high gloss, high fullness, and excellent weather resistance, and is used in medium and high-grade amino baking varnishes and polyurethane topcoats. However, the current water-based saturated polyester resin products have the defects of low solid content in construction, easy hydrolysis, and...
