Abstract

The invention relates to a high-performance fluororesin coating applied to coiled steel. The coating consists of the following components in parts by weight: 23-30 parts of polyvinylidene fluoride resin, 9-13 parts of thermosetting acrylic resin, 50-57 parts of an organic solvent and 1-17 parts of pigment. The coating disclosed by the invention is scientific and reasonable in ingredient proportion, relatively low in cost, better in weather fastness, solvent resistance, drug resistance, machinability and wear resistance, and excellent in adhesive force.

Description

Technical field [0001] The invention belongs to the field of coatings, in particular to a high-performance fluororesin coating for steel coils. Background technique [0002] Pre-coated metal coils are organic coatings / metal composite plates that are sold in rolls or single sheets after coating the rolled metal sheets. So it is also called organic coated steel plate, color steel plate and so on. Users can directly process it into various products or parts without painting. Nearly 90% of the coil steel topcoats currently produced in my country are polyester topcoats, which cannot meet the needs of customers. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a high-performance fluororesin coating for coiled steel, which has scientific and reasonable composition ratio, low cost, good weather resistance, solvent resistance, and Chemical properties, processability, abrasion resistance and excellent adhe...
