摘要
采用钛酸酯干法改性水镁石,通过测试活化指数,确定最佳改性条件。对比考察水镁石和改性水镁石对UPR/水镁石复合材料的影响。结果表明:改性水镁石可以明显降低体系黏度;水镁石可以改善UPR浇铸体的阻燃性能,改性水镁石可以提高阻燃效率;水镁石的加入还可以提高UPR/水镁石复合材料拉伸性能;水镁石的加入会严重影响材料的冲击强度,但改性水镁石可以改善冲击性能。
The titanic acid ester was used to modify the brucite by dry method modification, and the optimal modifying condition was found according to the test of activation index. The flame retardance and mechanical property of UPR/brueite composite were examed, the test result indicated that the tensile strength and mechanical property of UPR moulding system could be improved with the brucite added in,when the brucitc was modified by titanic acid ester, the flame retarding ability increased and the viscosity of system decreased. The modified brucite could improve the tensile strength. Brucite could affect the impact property of composite material,but it would change better when the modified brucite was taken.
