Abstract

The invention relates to double-component waterborne polyurethane adhesive and a construction method for paving a stadium. The double-component waterborne polyurethane adhesive comprises, by weight, a component A, a component B and 70-140 parts of deionized water, wherein the component A comprises, by weight, 6-20 parts of water-dispersible isocyanate; the component B comprises, by weight, 40-60 parts of waterborne hydroxyl acrylic acid dispersion, 5-8 parts of flexible plasticizing auxiliaries, 0.2-0.5 part of nonionic surfactant, 0.02-0.06 part of defoaming agent, 1-3 parts of pigment and 1-2 parts of antioxidant. The double-component waterborne polyurethane adhesive used for paving the stadium has the advantages that the adhesive is reasonable in raw material formula, excellent in performance and environmentally friendly; the adhesive is good in initial adhesiveness, high in toughness, good in resilience and excellent in physical performance by adding the flexible plasticizing auxiliaries.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, in particular to a two-component water-based polyurethane adhesive and a construction method for paving a stadium. Background technique [0002] At present, the pavement materials of sports venues are mainly solvent-based polyurethane adhesives and solvent-based two-component polyurethane plastics. The organic solvents used are flammable, explosive, volatile, and smelly, causing air pollution and public nuisance problems when used. At the same time, the existing two-component polyurethane paving materials generally contain toxic and harmful substances such as TDI, MOCA, DOP, DBP, lead, mercury, and tin catalysts, which seriously damage the health of construction workers and users. [0003] With the enhancement of people's environmental awareness, the emission of volatile organic compounds (VOC) in traditional solvent-based coatings is limited. Water-based polyurethane, which uses water ...
