摘要：

以聚氨酯为胶料、粉煤灰和CaCO₃为填料制备了仿瓷砖，进行力学性能测试和SEM扫描分析。结果表明，填料的添加量为72~78%、压制强度为21~109 MPa时，添加粉煤灰和CaCO₃的仿瓷砖的最大破坏强度为3 300 N和2 300 N，最大断裂指数为50 MPa和35 MPa，最小耐磨损体积分别为289 mm³和445 mm³，最小吸水率为0.95%和0.85%。粉煤灰的综合增强作用好于CaCO₃。

Abstract:

We prepared imitation tiles with polyurethane as adhesive and fly ash and CaCO₃ as filling.We also performed their mechanical performance test and SEM scanning analysis.Results show that the maximal rupture modulus of fly ash and CaCO₃ filled imitation tile of 3 300 N and 2 300 N, the maximal damage strength of 50 MPa and 35 Mpa, the minimal wear resistance volume of 289 mm³ and 445 mm³ and the minimal water absorption rate of 0.95% and 0.85% are reached when filling content and forming strength are 72%~78% and 21~109 MPa.The synthetical enhancement effect of fly ash is better than that of CaCO₃.

Key words: polyurethane, imitation tile, fly ash, CaCO3
