Environment-friendly color plate

Abstract

The invention discloses an environment-friendly color plate. The environment-friendly color plate comprises a color plate substrate, wherein a first passivation layer, a first anticorrosive layer anda first tin coating layer are arranged on the upper surface of the color plate substrate outwards sequentially; a second passivation layer, a second anticorrosive layer and a second tin coating layerare arranged on the lower surface of the color plate substrate outwards sequentially; outer surfaces of the first tin coating layer and the second tin coating layer are coated with waterborne paint layers. The environment-friendly color plate has the effects of being environmentally friendly, high-temperature-resistant, good in heat insulation, pollution-free and good in coating impact resistanceand bending resistance.

Description

technical field [0001] The invention relates to a heat-insulating and anti-corrosion VCM color steel plate, which belongs to the field of building materials. Background technique [0002] Color steel plate, also known as color profiled tile, is a profiled plate made of color-coated steel plate, which is rolled and cold-bent into various wave shapes. Mainly suitable for industrial and civil buildings, warehouses, special buildings, roofs, walls, and interior and exterior wall decoration of large-span steel structure houses, etc., with light weight, high strength, rich color, convenient and quick construction, earthquake resistance, fire prevention, rainproof, and long life Long, maintenance-free and other characteristics, has been widely promoted and applied. The color steel plate is installed on the roof, which is easy to generate high temperature under the sun, which makes the indoor temperature also high, and it is easy to be corroded under the long-term rainwater, which ...

AI Technical Summary

Problems solved by technology

The color steel plate is installed on the roof, and it is easy to generate a high temperature under the sun, which makes the temperature in the house also high, and it is easy to be corroded under the rain for a long time, which will affect the use effect of the color steel plate

[0003] 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 has high requirements on 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

Moreover, the above-mentioned 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 the environment.

Moreover, in practice, it is found that most water-based resins have the characteristics of slow drying speed, low gloss, poor chemical resistance, and lower solid content than oil-based resins, resulting in poor coating effects or unable to meet the actual production process requirements.
