Abstract

The invention discloses a park grade thermosetting negative ion powdery paint, which comprises the following raw materials in parts by weight: 50 to 62 parts of polyester resin with terminal carboxyl groups, 3 to 5 parts of hydroxyalkyl amide curing agent, 7 to 8 parts of negative ion additive, 0.2 to 0.5 part of dispersant, 0.7 to 1 part of levelling agent, 0.3 to 0.5 part of degassing agent, and 25 to 35 parts of filler and pigment. The invention also relates to a preparation method and applications of the provided paint. The paint has the basic functions of powdery paint, also has the function of releasing park grade negative ions in a long term, and thus has a vast market application prospect.

Description

technical field [0001] The invention relates to a park grade thermosetting negative ion powder coating, in particular to a park grade thermosetting negative ion powder coating, and also relates to a preparation method and application of the park grade thermosetting negative ion powder coating. Background technique [0002] Thermosetting powder coatings are widely used in various fields due to their advantages of no organic solvent, good environmental protection, high utilization rate, and convenient storage and transportation. As we all know, the negative ion function has a health care function for human health, so people have always hoped to obtain a thermosetting powder coating with a long-term release function of negative ions. In recent years, related technologies have been published. For example, the Chinese invention patent with the publication number CN101225278A discloses a negative ion powder coating. By adding negative ion additives to the powder coating, the powde...
