Preparation method of composite rubber floor for gymnasium

The invention discloses a preparation method of a composite rubber floor for a gymnasium. The method comprises the following steps: (1) mixing an isocyanate adhesive with acetone evenly and adding ultrafine rubber powder for mixing evenly to obtain a glue solution for later use; (2) adding acetone to rubber particles, making the surfaces of the particles sticky, then adding high abrasion furnace black, polyvinyl chloride, glass fiber, tourmaline powder and hexacyclic stone powder and mixing evenly to obtain a mixed base material; and (3) adding the glue solution obtained in the step (1) to the mixed base material obtained in the step (2), mixing evenly and pressing the obtained mixture into a floor base material in a hot pressing manner. According to the preparation method, the wear resistance of the composite rubber floor can be improved and the production cost can be reduced. 本发明公开了种体育馆用复合橡胶地板制备方法，包括如下步骤：1)将异氰酸酯胶粘剂与丙酮混合均匀，然后加入超细橡胶粉混合均匀后，得到胶液，备用；2)向橡胶颗粒中加入丙酮，使颗粒表面黏稠化，然后再加入高耐磨炭黑、聚氯乙烯、玻璃纤维、电气石粉、六环石粉，进行均匀混合，得到混
