Water-based white polyester coil coating special for aluminum ceiling finish paint and preparation method of water-based white polyester coil coating

Abstract

The invention discloses water-based white polyester coil coating special for aluminum ceiling finish paint and a preparation method of the water-based white polyester coil coating. The coil coating is prepared from, by weight, 5%-20% of deionized water, 2%-4% of solvent, 1%-2% of dispersing agent, 0.5%-1% of catalyst, 5%-10% of amino resin, 1%-2% of adherence promoter, 0.3%-0.5% of antifoaming agent, 0.3%-0.6% of flatting agent, 20%-40% of titanium dioxide, 5%-10% of water-based polyester modified epoxy, 30%-50% of water-based organosilicone modified polyester resin and 1%-3% of modifier. The flexibility of the coil coating can meet the construction requirement of an aluminum ceiling, and the advantage of being environment friendly is achieved. The easy-to-implement preparation method of the water-based white polyester coil coating for the aluminum ceiling finish paint is further disclosed.

Description

Technical field [0001] The present invention involves fine chemical coating technology fields, which specifically involves coil coatings and preparation methods for an aluminum roller coating. Background technique [0002] Aluminum roller coating is currently widely used raw materials for building decorative boards. Among them, building products that need to use aluminum roller coating include: aluminum -plastic boards, aluminum skyflowers, large building inner walls and outer wall panels, industrial plant roof tile tilesPanels, advertising panels, civil decorative door panels, home decoration wall panels, furniture panels, home appliance panels and digital product metal panels, etc.The color of aluminum roller coating is rich in color, and almost all colors of nature can be reproduced. At the same time, through different coatings and coating techniques, 3D, stereo patterns, simulating stone texture, tree texture, leather texture and metal texture can be presented.Among them, alu...
