马赛克免网格成联布点胶胶粘剂的研制

Development of Dot-mounting Adhesive for Mosaics without Mesh

马赛克传统的成联方式为纸贴成联和网贴成联,这两种成联方式虽然在一定程度上解决了马赛克铺设问题,但是粘接性和定型性差。免丝网布点胶胶粘剂使用改性聚氨酯做附着力促进剂,具有粘接力强、施胶量少,不影响马赛克与水泥(或陶瓷胶)的粘接效果,定型性好,固化后有一定的硬度和柔韧性等优点,彻底解决了铺贴定型性困难的难题。同时,点胶胶粘剂含有较低的VOC(挥发性有机物),不含重金属、无毒无害、耐水耐候性好、无需丝网基材,适用于各种材质的马赛克。

The traditional mosaic mounting method was by paper or plastic net which help to pave the mosaic but with weak adhesion and stereotype.The dot-mounting adhesive use the modify polyurethane to reinforce the adhesion by less amount,and do not affect the adhesion between mosaic and cement.Overcome the weakness of the tradition mounting methods.This adhesive with low VOC,heavy-metal free,good water-resisted,mounting by adhesive itself,can be used on mosaics made of usual materials.
