Problems solved by technology

[0003] Acrylic coating agent is one of the most common coating agents due to its good overall performance and low price. The organic solvent-based coating agent is polyacrylate toluene solution, which has good film-forming properties, smooth and soft film, and is easy to bake. Dry, but because it contains 80% toluene solvent, it is flammable, explosive and pollutes the environment

Abstract

The invention relates to a micro-bubble elastic polyurethane waterproof coating. The micro-bubble elastic polyurethane waterproof coating is characterized by comprising the following ingredients in parts by weight: 60-100 parts of polyurethane, 10-20 parts of isocyanate, 10-20 parts of water, 10-20 parts of zinc oxide, 0.1-1.0 part of talcum powder, 0.1-1.0 part of surfactant, 0.1-1.0 part of catalyst, 1-10 parts of hydroxypropyl methylcellulose, 80-100 parts of packing and 10-20 parts of plasticizer; the packing is any one of calcium carbonate, talcum powder and silicon dioxide; the plasticizer is any one of paraffin wax, castor oil, bisphthalate and stearic acid; the catalyst is methyldiethanolamine; and the surfactant is an anionic surfactant. The micro-bubble elastic polyurethane waterproof coating provided by the invention is safe and environment friendly because the organic solvent is adopted; and the coating has the advantages of easiness for coating and drying, good film forming property and smoothness.
