Waterborne polyurethane elastic floor
The invention discloses waterborne polyurethane elastic floor. The waterborne polyurethane elastic floor comprises a rigid base layer, a gypsum-based leveling layer, an intermediate polyurethane elastic material coat, a sound absorbing layer and a top waterborne polyurethane coat; the rigid base layer is composed of 120 to 140 parts of cement, 40 to 50 parts of graded joint sand, 20 to 30 parts of gravel, 35 to 45 parts of cross-linking agent and 60 to 80 parts of water by weight; the intermediate polyurethane elastic material coat is composed of 60 to 70 parts of elastic rubber, 40 to 50 parts of waste tire powder and 10 to 20 parts of waste plastic; the sound absorbing layer is composed of 70 to 80 parts of elastic rubber, 30 to 40 parts of mineral cotton, 25 to 35 parts of porous silica gel micro-bead and 15 to 20 parts of organic montmorillonite. The waterborne polyurethane elastic floor is especially suitable for sport fields and has skid resistance, compression resistance, noise reduction and the like functions.
