Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0022] This case proposes a highly weather-resistant, strong-corrosion-resistant lithified color steel plate of an embodiment, which is sequentially provided with a corrosion-resistant layer, a weather-resistant layer and a steel plate layer from top to bottom;

[0023] Wherein, the anti-corrosion layer comprises the following materials by weight:

[0024]

[0025] The formulation of the anti-corrosion layer is based on vinyl ester resin, which itself has good bonding performance and corrosion resistance. Polytrifluorochloroethylene is used to further increase the anti-acid, alkali and seawater erosion of the lithified color steel plate. ability; acetylene-propylene copolymer is used to improve the cohesion and hot-press viscosity of vinyl ester resin system, reduce the surface shri...

Abstract

The invention relates to a high weather resistance and strong corrosion resistance type lithification color steel plate. The high weather resistance and strong corrosion resistance type lithification color steel plate is sequentially provided with a corrosion resistance layer, a weather resistance layer and a steel plate layer from top to bottom, wherein the corrosion resistance layer comprises, by weight, 100 parts of vinyl ester resin, 20-24 parts of polychlorotrifluoroethylene, 10-12 parts of acetylene-propylene copolymer, 6-8 parts of parachlorobenzoic-acid n-butyl ester and 8-10 parts of silica powder. Through the improvement of the lithification color steel plate formula, the lithification color steel plate itself not only has attractive appearance, but also has strong anti-ultraviolet, corrosion resistant and impact resistant performances, adhesive force between the membrane layer and the base material is good when the lithification color steel plate is in harsh environment for a long time, and the lithification color steel plate has no dehiscence, no exfoliation and no blister.

Description

technical field [0001] The invention relates to a color steel plate, in particular to a lithified color steel plate with high weather resistance and strong corrosion resistance. Background technique [0002] As the scope of application of color steel plates in the field of building materials is expanding day by day, the product types of color steel plates are also diversified. However, due to the relatively low investment in equipment for color steel plates, some low-tech manufacturers have also entered this field. Out of control of costs and pursuit of profits, the quality of color steel plates produced by some manufacturers has appeared. or environmental issues. [0003] Due to its characteristics, the lithified color steel plate with anti-corrosion properties is often used in occasions that require high corrosion resistance, such as chemical equipment, ship building materials, etc. These plates need to have excellent anti-corrosion and anti-ultraviolet properties. It ne...
