Abstract

The invention provides a water-based paint applied in aluminum-plastic plates and a color steel coiled material. The water-based paint comprises the following components by weight: 30-55 parts of water soluble acrylic resin, 5-10 parts of water-based polyurethane resin, 4-10 parts of water soluble amino resin, 0.1-2 parts of a water-based dispersion agent, 0.1-2 parts of a water-based leveling agent, 0.1-2 parts of a water-based defoaming agent, 20-30 parts of water for the paint, 3-8 parts of an adhesion promoter, and 0.5-2 parts of a nano fumed silica slurry. The water-based paint has the main volatile which is water, thereby having no harm to the environment and operators. The water-based paint has the product quality which is equal to or slightly higher than the coating effect of an oily product. Moreover, the water-based paint has fast drying speed, can satisfy continuous and high-speed production in aluminum-plastic plate industry, and does not affect the production efficiency. Compared with an oily acrylic amino stoving varnish, the water-based paint has excellent solvent resistance, and has quite good market popularizing value.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a water-based coating applied to aluminum-plastic panels and color steel coils. Background technique [0002] At present, the most common surface coating products for decorative aluminum-plastic panels on the market are acrylic amino baking varnish, polyester amino baking varnish, epoxy baking varnish, etc. They are all oily products, and their common disadvantages are: all use toluene, di Toluene, ethyl acetate, butyl acetate and other harmful volatile solvents. It requires high construction conditions and is extremely harmful to the environment, which greatly increases the chances of operators and users suffering from respiratory diseases, reproductive system diseases, cancer and other malignant diseases. And the above-mentioned several types of products all contain a large amount of harmful heavy metals, which will remain in the coating for a long time and seriously affect t...
