Problems solved by technology

Nitriding treatment also improves the corrosion resistance and thermal fatigue resistance of the working surface of the mold to a certain extent, but the improvement of the corrosion resistance and wear resistance of the mold alone by nitriding treatment cannot meet the production requirements

[0073] Step 3, preparation of film coating:

[0074] a1. Take PEEK resin powder, acetone, benzyl alcohol, caprolactam-based acryloxysilane and polyoxyethylene polyoxypropylene polyether, send to the reactor and stir and disperse in the reactor, control the temperature in the reactor at 55- 60°C, the stirring speed is 350-450r / min, and the stirring time is 60-75min to obtain the PEEK resin mixture;

[0075] a2. Dry the WC powder and Co50 alloy powder at a temperature of 120-130°C to remove crystal water in the powder;

[0076] a3. Add the WC powder, Co50 alloy powder, graphite powder, and hydroxyl-terminated polyacrylate in step S2 into the reactor and stir evenly. The stirring speed is 600-750r / min, and the stirring time is 70-90min. The temperature is at 43-46°C to obtain the film coating;

[0077] Step 4. Laser cladding: Take out the metal sheet treated in step 1 and cool it to room temperature to 90-100°C, add a binder into the film coating, make it into a paste, and plac...

Abstract

The invention discloses a corrosion-proof wear-resistant protective film for the surface of a metal sheet. A film coating is prepared from the following raw materials in parts by weight: 20-30 parts of PEEK resin powder, 20-25 parts of acetone, 5-9 parts of benzyl alcohol, 0.8-1.5 parts of caprolactam acryloxysilane, 3-5 parts of WC powder, 6-9 parts of Co50 alloy powder, 3-5 parts of graphite powder, 0.5-1 part of polyoxyethylene polyoxypropylene polyether and 0.5-1 part of hydroxyl-terminated polyacrylate. A film is prepared according to the following steps: step 1, pre-treatment of the metal sheet; step 2, preparation of caprolactam acryloxysilane in the raw materials of the film coating; step 3, preparation of the film coating; step 4, laser cladding; and step 5, after-treatment of themetal sheet. The corrosion-proof wear-resistant protective film for the surface of the metal sheet, disclosed by the invention, has the characteristics of high bonding strength with metal, convenientconstruction, no vertical plane flow, no curing shrinkage, excellent corrosion resistance and wear resistance and the like, and is capable of improving the quality of the metal sheet and prolonging the service life of the metal sheet.

Description

technical field [0001] The invention belongs to the technical field of surface processing of metal plates, and in particular relates to an anti-corrosion and wear-resistant protective film on the surface of metal plates. Background technique [0002] In recent years, all kinds of metal plates have been widely used, but the metal plates are exposed to the atmosphere for a long time, and often lose their decorative effect due to serious erosion and deformation; some chemical metal equipment and pipelines are damaged due to poor wear resistance and corrosion resistance. affected the service life. [0003] The most common failure mode of sheet metal is basically the failure mode of the working surface of the sheet. If the surface treatment of the plate is carried out properly, the corrosion resistance and thermal fatigue resistance of the plate can be greatly improved, thereby improving the quality of the metal plate and prolonging the service life of the plate. At present, me...
