Ultraviolet light curing fluorocarbon paint and preparation method thereof

Abstract

The invention discloses an ultraviolet light curing fluorocarbon paint and a preparation method thereof, and belongs to the technical field of paints. The ultraviolet light curing fluorocarbon paint is used for heat transfer printing, and is prepared from the following ingredients in percentage by mass: 45 to 55 percent of organic fluorine light-cured resin, 25 to 35 percent of active monomers, 10 to 15 percent of solvents, 0.2 to 0.5 percent of flatting agents, 0.2 to 0.5 percent of antifoaming agents and 2 to 4 percent of photoinitiators. All of the ingredients are uniformly mixed in sequence to obtain the ultraviolet light curing fluorocarbon paint provided by the invention. The ultraviolet light curing fluorocarbon paint has the advantages that fluorocarbon resin with excellent weatherability and anti-corrosion performance is selected to be matched with acrylic resin with excellent weatherability and polyfunctional active monomers, so that a coating film has good hardness and adhesive force; meanwhile, the excellent weatherability is realized; the paint is particularly applicable to outdoor decoration plate materials, and has great market popularization value.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an ultraviolet light curing fluorocarbon coating and a preparation method thereof. Background technique [0002] UV-curable coatings have the advantages of no volatile organic compounds (VOC), less environmental pollution, fast curing speed, energy saving, good coating performance after curing, and are suitable for high-speed automatic production. However, ordinary UV-curable coatings The outdoor weather resistance is very poor, and it cannot or is rarely used as outdoor decorative materials; fluorocarbon coatings are coatings with fluororesin as the main film-forming substance. Particularly superior weather resistance, heat resistance, low temperature resistance, chemical resistance. [0003] At present, fluorocarbon coatings can be divided into one-component curing fluorocarbon coatings and two-component curing fluorocarbon coatings; one-component curing fluorocarbon coatings...

[0002] UV-curable coatings have the advantages of no volatile organic compounds (VOC), less environmental pollution, fast curing speed, energy saving, good coating performance after curing, and are suitable for high-speed automatic production. However, ordinary UV-curable coatings The outdoor weather resistance is very poor, and it cannot or is rarely used as outdoor decorative materials; fluorocarbon coatings are coatings with fluororesin as the main film-forming substance. Particularly superior weather resistance, heat resistance, low temperature resistance, chemical resistance

[0003] At present, fluorocarbon coatings can be divided into one-component curing fluorocarbon coatings and two-component curing fluorocarbon coatings; one-component curing fluorocarbon coatings need to be baked at high temperature, which limits its application range; The coating has the following disadvantages: first, the curing time of the two-component fluorocarbon coating system is long, and it usually needs to be baked at 80°C for 1 hour to meet the performance requirements; second, the coating contains a large amount of volatile organic compounds (VOC), which is harmful to Environmental pollution is extremely serious, and resources and energy are wasted at the same time. Therefore, it is necessary to improve the fluorocarbon coatings in the prior art to improve their performance and reduce their pollution.
