Problems solved by technology

[0003] However, under normal circumstances, after a long period of storage, even those coated with PVDF, the surface of the aluminum-plastic panel with a certain anti-fouling performance will be stained and dirty by dust, oil, etc., which will affect the appearance of the decoration. These outdoor decoration materials need to be cleaned and maintained regularly

Embodiment 1

[0064] Example 1: 33.3 g of 15% nano silicon oxide 1115 (particle size 4 nm), 3.1 g of 40% aliphatic polyurethane R1005, and 63.6 g of water. Add 150mg of wetting agent polyether-modified silicone BYK346 under stirring condition. Finally, a clear and transparent solution was obtained. Keep stirring for at least thirty minutes. The final solution was coated on the surface of the aluminum-plastic panel with a wire rod of 6 μm, and dried and cured at 120 degrees for one minute. The paintability of the coating solution finally obtained was 5, the antifouling ability of the coating was 7, and the coating adhesion was 5.

Embodiment 2

[0065] Example 2: 33.3 g of 15% nano silicon oxide 1115 (particle size 4 nm), 2.5 g of 40% aliphatic polyurethane R1005, and 64.2 g of water were mixed. Add 250mg of wetting agent polyether-modified silicone BYK346 under stirring condition. Finally, a clear and transparent solution was obtained. Keep stirring for at least thirty minutes. The final solution was coated on the surface of the aluminum-plastic panel with a wire rod of 6 μm, and dried and cured at 120 degrees for one minute. The paintability of the coating solution finally obtained was 5, the antifouling ability of the coating was 7, and the coating adhesion was 5.

Embodiment 3

[0066] Example 3: 33.3 g of 15% nano silicon oxide 1115 (particle size 4 nm), 2.1 g of 40% aliphatic polyurethane R1005, and 64.6 g of water were mixed. Add 250mg of wetting agent polyether-modified silicone BYK346 under stirring condition. Finally, a clear and transparent solution was obtained. Keep stirring for at least thirty minutes. The final solution was coated on the surface of the aluminum-plastic panel with a wire rod of 6 μm, and dried and cured at 120 degrees for one minute. The paintability of the coating solution finally obtained was 5, the antifouling ability of the coating was 7, and the coating adhesion was 5.

Abstract

The invention provides a paint composition which comprises an aqueous continuous liquid phase, silicon dioxide particles, fatty group polyurethane particles, and siloxane modified by fatty alcohol polyethenoxy ether and / or polyether, wherein the silicon dioxide particles are dispersed in the aqueous continuous liquid phase, and the volume average particle size of the silicon dioxide particles is less than 150 nm; the weight of the siloxane modified by the fatty alcohol polyethenoxy ether and / or polyether is higher than 0% and lower than 15%, based on the weight of the silicon dioxide particles; the pH value of the composition is not lower than 5; and the weight ratio of silicon dioxide particles to polyurethane is 4:1 to 9:1. The invention also provides an anti-foul easy-cleaning product with a coating formed by the composition and a preparation method thereof.

Description

technical field [0001] The invention relates to a coating composition, an anti-fouling and easy-cleaning product and a preparation method thereof, in particular to a coating composition for forming an anti-fouling and easy-cleaning coating on an aluminum-plastic plate, and a method for preparing a product from the composition And stain-resistant easy-to-clean articles, especially aluminum-plastic panels, having a coating made from the composition. Background technique [0002] Aluminum-plastic panel is a new type of decorative material for indoor and outdoor, which can be used in curtain walls, signs and other places. Due to the combination of metal's noble texture and easy processing characteristics, and plastic's light weight and low price, aluminum-plastic panels quickly become a new building decoration material, and gradually extend to the advertising sign industry. The aluminum-plastic panel is mainly composed of polyethylene in the middle and upper and lower layers of...
