Polyurea terrace and preparation method thereof
The invention provides a polyurea terrace and a preparation method thereof. The polyurea terrace mainly comprises an elastomer base layer and a top facing layer, wherein the elastomer base layer is prepared from a polyurethane material, and the top facing layer is prepared from a component A and a component B; the component A is prepared from 40 to 50 parts by weight of polyether amine and 50 to 60 parts by weight of diethyl ester, and the component B is prepared from 30 to 35 parts by weight of polyether polyol and 65 to 70 parts by weight of isocyanate, and the weight ratio of the component A to the component B is (63 to 65):(35 to 37). The preparation method comprises the steps of 1) directly knife-coating the polyurethane material on a base to form the elastomer base layer by using a dentiform scraper; 2) drawing wood grains on the elastomer base layer prepared in step 1); 3) mixing the component A and the component B, stirring uniformly, and roller-coating the elastomer base layer prepared in step 2) to form the top facing layer by using a roller. According to the polyurea terrace, a double-component and solvent-free polyurea material is adopted as the top facing layer, thus enhancing the abrasion resistance and scratch resistance of the terrace; besides, the polyurethane material is adopted as the elastomer base layer, thus being capable of effectively protecting joints and relieving fall damage.
