Plastic-aluminum sheet metal imitating paint and preparation thereof

Abstract

The invention discloses imitation aluminum-plastic board metallic paint, which is characterized in that the metallic paint comprises a first component which comprises weather-resistant solidifying agent and thinning agent; a second component which comprises fluoro resin, poly-fluorine-silicon resin, aluminum powder, flow agent and the thinning agent; when being used, the mixed rate of the weight of the first component and the second component is 1:8. The invention also discloses a preparation method for the imitation aluminum-plastic board metallic paint. The imitation aluminum-plastic board metallic paint has the advantages that the metallic paint is directly sprayed on the wall surface, the construction is convenient, the paint is inexpensive, the paint film is artistic and twinkles with a metallic luster, and the metallic paint has the effect of the metal aluminum-plastic board; the metallic paint has super weather resistance, the service life is long and can reach up to 25 years; the metallic paint also has super pollution resistance, the surface is smooth, the adhesion is very small, the metallic paint has the lotus effect, which can not be polluted and is very easily to be cleaned; the metallic paint has excellent gloss retention and color retention and is wear resistant, and the scratch resistance is good; the preparation method is simple, and the large-scale production is easy to be performed.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a metal paint for imitating aluminum-plastic panels and a preparation method thereof. Background technique [0002] Before the 1990s, domestic exterior wall protective and decorative coatings were mainly ordinary latex paints and solvent-based exterior wall paints. The exterior walls decorated with these coatings were prone to aging and fading due to the low technical content at that time. , Peeling, can not achieve satisfactory decorative protection effect. With the development of the times, the construction industry is full of vitality, and many super high-rise buildings have appeared. At the same time, the city is required to be clean and beautiful, to have a modern metropolis, and to be in line with international standards. This puts forward higher requirements for modern architectural decorative protective coatings. Therefore, some better coating varieties have ...

Problems solved by technology

Its structure is unique and very stable, endowed with many excellent properties such as super weather resistance, self-cleaning, chemical corrosion resistance, etc., which can make the durability of building finishes reach more than 25 years. Once decorated, it does not need cleaning and maintenance for 20 years. It is incomparable to any kind of paint, and it is very suitable for the decoration requirements of modern architectural exterior wall paint. However, the fluorocarbon paint at that time was insoluble in solvent (powder type), and it had to be baked at a high temperature of 200°C to form a film. For large-scale spraying construction on site, we can only find a suitable carrier, spray the paint on the aluminum-plastic panel and dry it, so that we can only process it piece by piece in a small area of ​​the factory, and then install it on site by relying on the keel. This is the aluminum-plastic panel fluorine Carbon paint, which not only increases the cost, but also brings inconvenience to design and construction. Moreover, the aluminum-plastic panel itself as the carrier is easily oxidized and susceptible to adverse effects such as moisture. If the performance of the protective finish is not good, it is easy to cause damage, effect
