Waterproof polyurethane coating and preparation method used in construction. Its 1.0:1.0 to 2.5 cents in a weight ratio of the combination of the Group A points A and B, wherein Group A comprises 50 to 130 parts sub highly crystalline polyester oligomer, 18 to 45 parts of polyisocyanate, 5 ~ 15 parts of phthalate, 0.1 to 0.8 parts of the catalyst, aqueous polyurethane waterproof coating, Part B contains 3 to 15 parts of a curing agent, 10 to 25 parts of a reinforcing agent, 17 to 35 parts of a lubricant, from 20 to 36 parts fillers, 5 to 18 parts pigment. The method chosen polar, high degree of crystallinity linear polyester and polyisocyanate reacting Part A, polyurethane waterproof coating wholesale, the Part A and Part B have very good cooperation of the two-component mixing cured elastomeric material under the action of tensile force soon crystal orientation, the material has a high tensile strength. Polyurethane waterproof coating: 1, waterproof coating at room temperature and viscous liquid, Baoding polyurethane waterproof coating, after coating cured to form seamless waterproof coating. 2, waterproof coating suitable legislation and, yin and yang angle, through structural layer pipes, raised detailed structure of the material, waterproof construction and other narrow spaces, complete waterproofing membrane can be formed on complex parts. 3, waterproof coating is a cold work construction, easy operation, low labor intensity.
