Abstract

The invention discloses a three-dimensional simulative wood grain powder coating for an aluminum profile and a preparation method for the three-dimensional simulative wood grain powder coating for the aluminum profile as well as a spraying method of the powder coating. The powder coating is composed of type A body powder and type B surface powder. The powder coating comprises saturated end carboxyl polyester resin, a TGIC curing agent, an HAA curing agent, acrylic resin and the like. The preparation method for the powder coating comprises: firstly pre-mixing the raw materials of the body powder and the surface powder, respectively; and carrying out melt extrusion, tabletting and cooling, crushing, fine crushing and sieving on the mixed raw materials to prepare the powder coating. A construction technology of the powder coating comprises: firstly spraying the body powder; after simply curing body powder, then spraying the surface powder to form a pattern; and finally curing and forming the powder coating. According to the coating film, not only is a decorative pattern effect on the surface ensured, but also the weather resistance of the coating is greatly improved compared with that of a common heat transfer printing coating, so that the cost performance of the aluminum profile is greatly increased.

Description

technical field [0001] The invention relates to a powder coating, in particular to a powder coating for aluminum profiles and a preparation method thereof. Background technique [0002] There are two main types of wood-grain powder coating products popular in the market today. The first type is made of weather-resistant powder coatings that are sprayed and cured to form a film, and then processed with wood-grain paper through thermal transfer technology. The second type is the weather-resistant powder coating after the first spraying construction and curing to form a film, and then spray the second powder to prepare the texture through the concave-convex rubber roller equipment, and then form a three-dimensional wood grain after curing to form a film. For the first type of powder, the wood grain texture is the ink on the wood grain paper penetrated into the coating. Now it is found in the market that this type of coating is easy to fade and has poor weather resistance; while...
