Abstract

The invention discloses tung oil embossment wood grain transfer paint and a preparation method and application thereof. The paint is prepared from, by mass, 50-65% of pure polyester, 6-10% of triglycidyl isocyanurate, 21-35% of wood powder, 0.5-1.0% of pigments, 2.0-3.0% of a flatting agent, 2.0-3.0% of a gloss enhancer and 0.5-1.0% of benzoin, wherein the sum of mass fractions of the raw materials is 100%. In preparation, all components are subjected to mixing, extruding, sheeting, slicing and grinding to obtain the paint, the paint is sprayed to surfaces of workpieces subjected to pretreatment, and high-temperature curing and transferring are performed to obtain sectional materials subjected to wood grain transfer. The paint is high in powder coating rate and low in powder consumption, and the prepared sectional materials are clear in texture, appropriate in concave-convex structure and extraordinary in stereo handfeel.

Description

technical field [0001] The invention relates to the technical field of powder coatings, in particular to a tung oil embossed wood grain transfer coating and a preparation method and application thereof. 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, there are mainly two types of wood grain transfer printing on metal materials. One is to use electrostatic spraying on the surface of electrostatic powder profiles to coat a layer of thermosetting organic polymer powder. Permeable coating; the other is the wood grain transfer electrophoretic profile, which is to form dense micro-pores through anodic oxidation of the substrate, and deposit metal ions or organic dyes in the oxidized pores by electrolysis or organic coloring, and then pass through Electrophoresis deposits water...
