Problems solved by technology

Although polyurethane has excellent properties, it also has certain limitations, for example, the hydrophilicity on its molecular chain—CH 2 The OH group is easy to absorb water, which leads to a decrease in the water resistance of polyurethane. In addition, as an organic polymer material, its flame retardancy is not very ideal, which reduces the water resistance and flame retardancy of the coating and limits the application of polyurethane coatings. scope

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-performance polyurethane coating. Background technique [0002] Polyurethane has good wear resistance, water resistance, solvent resistance and excellent mechanical properties, and is 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, for example, the hydrophilicity on its molecular chain—CH 2 The OH group is easy to absorb water, which leads to a decrease in the water resistance of polyurethane. In addition, as an organic polymer material, its flame retardancy is not very ideal, which reduces the water resistance and flame retardancy of the coating and limits the application of polyurethane coatings. scope. Contents of the invention [0003] Based on the technical problems existing in the ...
