Embodiment Construction

[0008] The present invention is a high-gloss and high-leveling powder coating, which is suitable for outdoor coating and is mainly made of the following raw material ratios in parts by weight: 50-70 parts of saturated hydroxyl polyester resin; 3.7-5.0 parts of triglycidyl isocyanurate 0.01-0.03 parts of anti-yellowing benzoin; 0.4-1.0 parts of leveling agent; 0.5-1.5 parts of wetting accelerator; 10-30 parts of filler; The acid value of the saturated hydroxyl polyester resin is 20-45 mgKOH / g; it also includes an active silicon coupling agent, the weight part of which is 0.5-2.0 parts.

[0009] The composition, active end group, functionality and relative molecular weight of polyester, as well as the type and amount of curing agent used are all important factors in determining the final properties of powder coatings. TGIC (Triglycidyl Isocyanurate) coating has excellent outdoor weather resistance, and the use of aliphatic epoxy curing agent reduces the UV absorption characteris...

Abstract

The invention discloses a high luster and high leveling powder coating which mainly consists of the following raw materials in parts by weight: 50-70 parts of saturated hydroxyl polyester resin, 3.7-5.0 parts of triglycidyl isocyanurate, 0.01-0.03 part of anti-yellowing benzoin, 0.4-1.0 part of leveling agent, 0.5-1.5 parts of wetting promoter, 10-30 parts of filler and 0.3-20 parts of pigment. The invention finally solves the problem of insufficient leveling and luster of the coating by means of coating formula optimization and mutual coordination of different assistants and of the mixed use of the wetting promoter and the leveling agent. According to the formula, the high luster and high leveling powder coating with mirror effect can be prepared and has brighter color. The invention has the same indoor and outdoor effect and improves the weather resistance as well.

Description

technical field [0001] The invention relates to a high gloss and high leveling powder coating. Background technique [0002] As a solvent-free coating, powder coating is economical, environmentally friendly, efficient, and excellent in performance, and is welcomed by people. With the increasingly stringent requirements for environmental protection, powder coatings have developed rapidly due to their low pollution, high decorativeness, and good comprehensive performance, and are gradually replacing traditional solvent-based coatings. The market for powder coatings is very wide at present, and its application ranges from the automotive industry to toys and mechanical pencils. The electrical industry has also turned to powder coatings in order to avoid the use of solvent paints. The wide application of powder coatings has benefited from the continuous research and development of powder coatings, and the performance of powder coatings has been improving and improving. However,...
