Abstract

The invention belongs to the technical field of paint, in particular to a high-definition wood grain transfer powder paint with graffiti resistance, a preparation method and a use thereof. The paint comprises the following raw materials in parts by weight: 50-200 parts of low hydroxyl polyester, 50-200 parts of carboxyl terminated polyester with medium acid value, 50-200 parts of high-hydroxyl polyester, 50-200 parts of carboxyl terminated polyester with high acid value, 230-400 parts of isocyanate and 17-50 parts of powder paint general auxiliary agent. The high-definition wood grain transferpowder paint with graffiti resistance is adopted, the prepared wood grain powder transfer coating is clear, and has good water resistance, smooth surface and good graffiti resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an anti-graffiti high-definition wood grain transfer printing powder coating, a preparation method and an application. Background technique [0002] Wood grain transfer printing is a common metal surface coating technology. It is a process and process of transferring the wood grain on the printing plate to the substrate through the transfer printing material. At present, the wood grain transfer printing of metal materials is mainly by electrostatic spraying on the surface of electrostatic powder profiles, coating a layer of thermosetting organic polymer powder, and curing at high temperature to form a coating with certain permeability on the surface of profiles. The wood grain is transferred to the surface of the aluminum part by transfer printing. On the one hand, the surface of the aluminum part is covered, so the surface of the aluminum part is not easy to fade, w...
