Problems solved by technology

Commonly used thermosetting and thermoplastic powder coatings are generally baked at a temperature above 180°C and cured for about 20 minutes. Such a high curing temperature limits the application of powder coatings to heat-resistant substrates such as metals; in the field of heat-sensitive substrates, due to its curing The temperature is too high to promote

Abstract

The invention discloses a low-temperature curing hammer tone powder coating, which is prepared from the following ingredients in parts by mass: 25-40 parts of polyester resin, 25-40 parts of epoxy resin, 10-25 parts of titanium pigment, 10-20 parts of a padding, 0.1-0.3 part of a hammer tone agent, 0-5 parts of a pigment and 0.5-2.0 parts of a low-temperature curing accelerant. The polyester resin and the low-temperature curing accelerant are matched for use, so that the curing temperature of the powder coating is 120-140 DEG C, and the curing time of the powder coating is 20min; the hammer tone agent is a modified cellaburate polymer; the mass ratio of polyester resin to epoxy resin is 1:1. The invention also provides a preparation method of the powder coating. The low-temperature curing powder coating prepared by the method has the advantages that the application range of the powder coating is enlarged to include heat-sensitive materials; the application range is expanded, and the powder coating has a hammer tone effect and favorable artistic quality and conforms to the modern aesthetic appreciation demand.

Description

technical field [0001] The invention relates to a powder coating, in particular to a low-temperature curing hammer grain powder coating. Background technique [0002] Powder coating has the advantages of environmental friendliness, low production cost and simple production process, and its application range is increasing. Commonly used thermosetting and thermoplastic powder coatings are generally baked at a temperature above 180°C and cured for about 20 minutes. Such a high curing temperature limits the application of powder coatings to heat-resistant substrates such as metals; in the field of heat-sensitive substrates, due to its curing The temperature is too high to promote. In addition, with the improvement of people's living standards, the requirements for quality of life also increase; powder coatings with hammer effect can cover the defects of the substrate, and at the same time, the appearance is closer to the needs of the public. Therefore, the application of hamme...
