光纤预制棒废料用于制备瓷砖背胶试验研究

Experimental research on the preparation of backing adhesive for ceramic tile with optical fiber preform waste

将光纤预制棒废料粉末添加到丙烯酸乳液和苯丙乳液复合液中,辅以硅烷偶联剂及其它助剂,制备了一种新型瓷砖背胶。通过试验确定背胶的最优配方为:m(丙烯酸乳液)∶m(苯丙乳液)∶m(光棒废料)∶m(硅烷偶联剂A-151)∶m(淀粉醚)∶m(分散剂)∶m(甲酸钙)=200∶50∶30∶15∶5∶6∶7。按JC/T547—2017对按最优配方制备的背胶进行性能测试,经热处理或浸水处理后,背胶粘结体系仍具有较高的粘结强度,表明其具有良好的耐热和耐水性。

A new type of backing adhesive for ceramic tile was prepared by adding the optical fiber preform waste powder to the mixed emulsion of acrylic acid and styrene-acrylic acid,supplemented by silane coupling agent and other necessary components. The optimum formula was as follows:acrylic emulsion∶styrene-acrylic emulsion∶optical fiber preform waste powder∶A-151∶starch ether∶dispersant∶calcium formate=200∶50∶30∶15∶5∶6∶7. According to the method specified in JC/T 547-2017,the performance of the best formula backing adhesive for ceramic tile was tested. It was found that the adhesive bonding system still had high bonding strength after heat treatment or water erosion. This indicates that the backing adhesive for ceramic tile has good heat aging resistance and water erosion resistance.
