Problems solved by technology

[0004] With the development of science and technology, especially petrochemical, automobile, metallurgy, national defense and other industries, more and more equipment and supporting facilities need to be applied to wear and high temperature resistance. It is easy to be gradually destroyed and loses its protective effect, and can no longer meet the special requirements of high temperature resistance and wear resistance
Polyphenylene sulfide is a material that can be used in the preparation of heat-resistant coatings. It has high strength, good size and high fatigue resistance. It does not deform under high temperature and high humidity conditions, but it is also There are disadvantages such as unstable friction coefficient, high wear rate and difficult processing when used alone, which limits its use to a certain extent.

Abstract

The invention discloses a wear-resistant high temperature-resistant organic coating steel plate. The wear-resistant high temperature-resistant organic coating steel plate comprises a substrate, a first galvanizing layer and a back paint layer are arranged on a lower surface of the substrate from up to down, and a second galvanizing, a fibrous layer, an alloy layer and a resin coating layer are arranged on an upper surface of the substrate from down to up. According to the wear-resistant high temperature-resistant organic coating steel plate, the surface of the substrate is coated with the fibrous layer, the alloy layer, and the resin coating layer; the fibrous layer can enhance the toughness of the steel plate, the alloy layer can effectively enhance the wear resistance of the steel plate,and in the resin coating layer, polyphenylene sulfide, polytetrafluoroethylene and polyether-ether-ketone resin are taken as main film forming substances, glass beads are taken as a reinforcing phase, and graphite is taken as a lubrication phase, so that the wear-resistant high temperature-resistant organic coating steel plate has excellent high temperature-resistance performance.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a wear-resistant and high-temperature resistant organic coated steel plate. Background technique [0002] Organic coated steel refers to the coating of natural or synthetic resins on the substrate. Organically coated steel sheets have the advantages of good corrosion resistance, bright colors, beautiful appearance, convenient processing and forming, high strength, and low cost, and are widely used in construction, household appliances, transportation and other industries. [0003] Traditional color-coated steel sheets are based on galvanized or galvalume-coated substrates, which are pre-treated and degreased, coated with chemical conversion coatings, primed, back-coated, and top-coated, followed by secondary baking. Ordinary organic-coated steel sheets use epoxy or polyester or polyurethane resin as the main film-forming substance of the undercoat, and polyester or silicon-mod...
