Wood grain transfer printing water paint, aluminum alloy wood grain transfer printing section and manufacturing method thereof

Abstract

The invention discloses a wood grain transfer printing water paint, an aluminum alloy wood grain transfer printing section and a manufacturing method thereof. The aluminum alloy wood grain transfer printing section respectively comprises an aluminum base material, a silane polymer protection layer, a priming paint layer, a finish paint layer and a wood grain transfer printing film from underside to surface thereof; the priming paint layer and the finish paint layer both are formed by the wood grain transfer printing water paint by means of electrostatic spraying, wherein the wood grain transfer printing water paint is prepared with water-base organic silicon modified acrylic resin, isocyanate curing agent, propylene glycol monomethyl ether, n-butyl alcohol, isobutyl alcohol, adhesion promoter, ultraviolet light absorber, flatting agent, thickening agent, antioxidant, defoaming agent and the balance of deionized water. According to the invention, the water paint is uniformly sprayed on the aluminum alloy base material by the electrostatic spraying method, after hot setting, an even, flat and smooth paint film is formed, and the high-quality aluminum alloy wood grain transfer printing section with the advantages, such as strong adhesive force, excellent covering power, strong resistance to corrosion, excellent weather fastness, difficult pulverization and color fading, is provided.

Description

[0001] technical field [0002] The invention relates to a water-based paint and its application field, in particular to a water-based paint for wood grain transfer printing, an aluminum alloy wood grain transfer printing profile and a manufacturing method thereof. [0003] Background technique [0004] 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 the electrostatic powder profile to coat a layer of thermosetting organic polymer powder, which is cured at high temperature to form a coating with certain permeability on the surface of the profile. Then cover the ink paper printed with wood grain pattern on the coating, using the principle of molecular diffusion, the ink paper penetrates into the coating to form a profile imitating wood grain color; the defect of this transfer printing method is that: due to the thermosetting organic polymer The weakness of the material itself l...

Problems solved by technology

Then cover the ink paper printed with wood grain pattern on the coating, using the principle of molecular diffusion, the ink paper penetrates into the coating to form a profile imitating wood grain color; the defect of this transfer printing method is that: due to the thermosetting organic polymer The weakness of the material itself leads to easy chalking and fading of the wood grain transfer printing, poor weather resistance and poor gloss of the coating

The other is the wood grain transfer printing electrophoretic profile, which is to form dense micro-pores through anodic oxidation of the substrate, and deposit metal particles or organic dyes in the oxidation pores by electrolysis or organic coloring, and after electrophoresis, the water-soluble varnish Or the color paint is deposited on the surface of the profile to form a uniform, smooth and smooth paint film, and the metal particles or organic dyes are deposited in the oxidation pores to make a product; the electrophoretic dyeing paint has uniform coating, strong adhesion, and coverage Good corrosion resistance, good weather resistance, not easy to pulverize and fade, etc., but the construction method of the electrophoresis process can only form a transfer layer with a thickness of 10 μm at most, resulting in a thin transfer layer and difficult to achieve diversification of colors. Moreover, the gloss of the product is too high to be controlled, and only a high-gloss coating can be formed, which distorts the obtained wood grain effect
