Abstract

The invention relates to powder coating and particularly relates to powder coating for MDF transfer printing and an application method of the powder coating. The powder coating is prepared from the following raw materials in percentage by weight: 53-90% of resin, 0-6.7% of a curing agent, 0.1-0.5% of a curing accelerant, 3-25% of auxiliaries, 5-30% of filler and 0.8-25% of pigment. After the powder coating is used for transfer printing, the texture is clear, the penetration is deep, the third dimension is strong, the transfer printing paper can be easily uncovered, the thermal transfer printing product is durable in use, and the patterns are not dropped, cracked or faded; moreover, the thermal transfer printing only achieves a surface decoration effect without changing the characteristics of the original glossiness, the wear resistance, the weather resistance, the acid and alkali resistance, and the like of the product. The invention also provides an application method of the powder coating.

Description

technical field [0001] The invention relates to a powder coating, in particular to a powder coating for MDF transfer printing and an application method thereof. Background technique [0002] Powder coating, often called dry paint, is an environmentally friendly product that is available in more varieties and colors. As a solvent-free decorative and protective material, powder coatings are widely used in various fields due to their advantages of cleanness, environmental protection and cost reduction. With the development of society, people continue to put forward higher requirements for the decorative and protective effects of powder coatings, and the types of designs and colors they pursue are becoming more and more colorful. Although natural wood and stone are the best decorative materials, but for the protection of the environment Problems such as and use cost make the use of these natural materials subject to certain restrictions. [0003] With the promotion of the appl...
