Method for improving paint firmness

Abstract

The present invention relates to a method for increasing the firmness of paint, which comprises the following steps: Step 1: Prepare materials, take 50-60 parts of epoxy resin, 80-90 parts of paint, 20-40 parts of polyamide resin, and 15 parts of phenolic resin ‑20 parts, 12‑18 parts of alumina, 15‑18 parts of magnetic powder, 8‑15 parts of quartz powder; step 2: drying, epoxy resin, polyamide resin, phenolic resin, alumina, magnetic powder, quartz powder respectively Put it in a microwave dryer with tin foil, turn on the power, and dry for 30-40 minutes; Step 3: Cool, take out the placed materials from the microwave dryer, and let it stand for 10-20 minutes in a natural environment at room temperature Minutes until fully cooled; Step 4: Mix and stir, place the cooled material in a ball mill and stir until uniform, and invert the stirred material in a curved glass container; Step 6: Stand still, put the filled paint Stand still for 40-60 minutes. In a word, the present invention has the advantages of easy operation, significantly increased paint firmness, low operating cost, and easy-to-achieve increased paint firmness.

Description

technical field [0001] The invention belongs to the technical field of chemical product production, and in particular relates to a method for increasing the firmness of paint. Background technique [0002] Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. This material can be coated on the surface of objects with different construction techniques to form a solid adhesion, certain strength, continuous solid film. The film formed in this way is commonly called a coating film, also known as a paint film or a coating, but the current paint is not firm enough, which will cause harm to the later adhesion, and is prone to peeling and rust. Organic compounds containing two or more epoxy groups, except for a few, their relative molecular mass is not high. The molecular structure of epoxy resin is characterized by active epoxy groups in the molecular chain, and the epoxy groups can be loca...
