Problems solved by technology

[0003] Today's powder coatings can basically be divided into pure epoxy powder coatings, epoxy / polyester hybrid powder coatings, pure polyester powder coatings, and acrylic powder coatings. Among them, pure epoxy powder coatings and pure polyester powder coatings Acrylic type powder coating has the characteristics of poor weather resistance, so it is not suitable for spraying outdoor products; the formula cost of acrylic type powder coating is relatively high, so it is difficult to promote it in the market; The weather-resistant powder coating has an absolute advantage, and various research institutions have done a lot of research on this type of powder coating. Due to the difference in formula, the elasticity, air permeability, leveling and Properties such as wear resistance and wear resistance are also quite different. The difference in various properties is often the difference in the additives of the formula components. Those skilled in the art know that the additives are added in less amounts, but the cost of the additives is relatively high. Therefore, the development of a powder coating formulation with lower cost and better leveling performance is a current research issue

Abstract

The invention relates to the technical field of preparation for powder coatings with special performances, and particularly relates to an ultra-level highlight powder coating formula and a preparation method thereof. The powder coating has the following formula components in parts by mass: 28-34 parts of epoxy resin, 28-34 parts of polyester resin, 1.5-3.5 parts of a levelling agent, 22-25 parts of titanium dioxide, 2.5-4.8 parts of barium sulphate, 0.1-0.6 part of benzoin, 0.2-0.6 part of an antioxidant, 0.02-0.28 part of ultramarine, 0.002-0.004 part of carbon black and 0.2-0.35 part of silicon dioxide. The coating film of the powder coating obtained by the technical scheme disclosed by the invention has a good levelling performance, the interface cured by the powder coating has good decoration performance, and the powder coating can be applied to surface protection on automobiles, household appliances, furniture and the like, as well as is low in use cost and suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of preparation of powder coatings with special properties, in particular to a formula of super-leveling high-gloss powder coatings and a preparation method thereof. Background technique [0002] The powder coating developed rapidly in recent years is a new type of solvent-free solid powder coating, which has the advantages of easy storage at room temperature, high utilization rate and easy construction. Since the advent of powder coatings, it has been widely recognized by consumers and developed rapidly. The preparation process of this new type of powder coating is usually prepared by mixing specific resins, pigments, fillers, curing agents and other additives in a certain proportion, and then through extrusion, crushing and other processes. [0003] Today's powder coatings can basically be divided into pure epoxy powder coatings, epoxy / polyester hybrid powder coatings, pure polyester powder coatings, and a...
