An environmentally friendly corrosion-resistant single-layer pet color-coated steel plate

Abstract

The invention discloses an environmental protection type single-layer PET (Polyethylene Terephthalate) colored film-covered steel plate, which comprises a steel plate base material, wherein chemical coatings and graphene-water soluble organic silicon modified acrylic resin primer layers are stacked in sequence on both the front surface and the back surface of the steel plate base material; a PET film is pasted on the graphene-water soluble organic silicon modified acrylic resin primer layer of the front surface; afterwards, a PE (Polyethylene) protecting film is pasted on the PET film. A preparation process of the environment protection type single-layer PET colored film-covered steel plate comprises uncoiling, sewing, washing, oven-drying, chemical coating, the oven-drying, primer coating, oven-drying solidification, PET film covering, cooling and PE protecting film covering. According to the film-covered steel plate provided by the invention, PVC (Polyvinyl Chloride) layers are replaced by adopting graphene-water soluble organic silicon modified acrylic resin primer; the film-covered steel plate has decorative attractiveness, favorable corrosion resistance and physical and mechanical performance at the same time, and accords with the development direction of an environment-friendly material.

Description

technical field [0001] The invention relates to a color-coated steel plate, in particular to an environment-friendly corrosion-resistant single-layer PET color-coated steel plate, which belongs to the field of composite materials. Background technique [0002] At present, color-coated panels are generally based on coiled galvanized steel sheets, cold-rolled steel sheets, etc., for surface degreasing, cleaning, and chemical coating treatment. After forming a layer of chemical conversion film on the surface of the substrate, apply glue and film. into a product. Coated steel plate not only has the advantages of ordinary coated steel plate, but also can customize various patterns and patterns according to needs, and has been widely used in household appliances, construction, office, furniture and other industries. [0003] Most of the coated steel plates on the market are PVC coated steel plates and PVC+PET coated steel plates. The films used in these two types of coated steel ...

AI Technical Summary

Problems solved by technology

[0003] Most of the coated steel plates on the market are PVC coated steel plates and PVC+PET coated steel plates. The films used in these two types of coated steel plates are all related to PVC materials. The production cost of PVC is relatively high, and plasticizers are required. Plasticizers have been included in the RoHS Candidate Restricted Substances List, and the PVC layer is easily crushed and not scratch-resistant
