Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a flame-retardant and antifouling polyurethane coating. Background technique [0002] Polyurethane has good wear resistance, water resistance, solvent resistance and excellent mechanical properties. At present, it has been widely used in elastomers, foam plastics, coatings, adhesives and biomedical materials. Polyurethane coatings are usually used in leather finishing, textile printing and dyeing, paper making, architectural coatings, adhesives, cast steel coatings and other fields. Although polyurethane has excellent properties, it also has certain limitations, such as poor flame retardancy and poor antifouling performance, which limit its application range. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a flame retardant and antifouling polyurethane coating, which has good water resistance, abr...
