Coil coating having special anode oxidation effect and special for aluminum plate coiled material and preparation method of coil coating

Abstract

The invention discloses coil coating having a special anode oxidation effect and special for an aluminum plate coiled material. The coil coating is characterized by being prepared from the following components in percent by weight: 2 to 10 percent of solvent, 0.5 to 1 percent of dispersing agent, 0.5 to 1 percent of catalyst, 5 to 10 percent of amino, 0.3 to 0.5 percent of defoaming agent, 0.3 to 0.6 percent of flatting agent, 1 to 2 percent of directional alignment agent, 0.5 to 1 percent of anti-static agent, 15 to 25 percent of nanoscale processed aluminum powder, 40 to 50 percent of polyester resin, 10 to 20 percent of fluorine-modified polyester resin and appropriate nanoscale color mixing color concentrate. After the coil coating disclosed by the invention is used on the aluminum plate coiled material, a surface effect which is equivalent to an anode oxidation effect can be generated.

Description

technical field [0001] The invention relates to the field of fine chemical coatings, in particular to a coil coating for aluminum plate roll coating and a preparation method thereof. Background technique [0002] Aluminum coil is the raw material of building decorative panels widely used at present. Construction products that need to use aluminum coil include: aluminum-plastic panels, aluminum ceiling gussets, large-scale building interior and exterior wall panels, industrial factory roof tile panels, advertising Use decorative panels. Civil decorative door panels, home decorative wall panels, furniture panels, home appliance panels, metal panels for digital products, etc. Aluminum coils are rich in color, and almost all colors in nature can be reproduced. At the same time, through different coatings and coating techniques, it can present 3D and three-dimensional patterns, simulating stone textures, tree textures, leather textures, metal textures, etc. Aluminum coils can b...

Problems solved by technology

However, there is a certain gap between the aluminum sheet and coil produced by the existing coil coating and the anodized aluminum sheet in terms of metal texture and color fineness. Metal spraying uses a specially designed formula and process to simulate anodic oxidation The successful case of the surface effect of the coil coating, but due to its special construction process, it is difficult for the conventional aluminum powder paint to paint the surface effect of anodic oxidation. Therefore, the industry has been eager to solve this technical problem
