Low-temperature curing baking type coating and preparation process

Abstract

The invention discloses a low-temperature curing baking type coating and a preparation process thereof, and relates to the technical field of coatings, the low-temperature curing baking type coating comprises the following raw materials by mass: 15-25 parts of acrylic resin, 15-25 parts of polyester resin, 1-10 parts of a diluent, 11-20 parts of amino resin, 2 parts of a catalyst, 2 parts of a rheological additive, 2 parts of an antifoaming agent, 2 parts of a stabilizer, and 1 part of a leveling agent. In this way, the defects existing in the background technology are overcome, the drying time is short, and the working efficiency can be improved easily.

Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to a low-temperature curing baking type coating and a preparation process. Background technique

[0002] Existing high-temperature baking paint and low-temperature PU paint either require higher temperature baking to cure, wasting energy, or require longer drying time (two-component PU paint) 3-4 hours in summer, 5-12 hours in winter, or even longer. The production efficiency is low, and the two-component PU paint contains expensive isocyanate, which has a greater impact on the human body and the environment.

[0003] Therefore, a solution is urgently needed. SUMMARY OF THE INVENTION

[0004] The purpose of the present invention is to provide a low-temperature curing baking type coating and a preparation process, so as to solve the deficiencies in the background technology, and the drying time is short, which is beneficial to the improvement of work efficiency.
