Water stop belt with bentonite modified by isocyanate and silane coupling agent
The invention discloses a water stop belt with bentonite modified by isocyanate and a silane coupling agent. The water stop belt is prepared from the following raw materials in percentage by weight: 40%-60% of bentonite, 5%-10% of a modifier, 2%-8% of a dispersing agent, 3%-8% of a water repellent agent, 5%-10% of an enhancer and 10%-25% of an additive. The bentonite is modified by adopting isocyanate and a silane coupling agent, so that the expansion rate of the bentonite is increased; bentonite can be well dispersed in the system through the alkyl coupling agent; the polyallylamine solves the problem that the mechanical property of a bentonite-based water-stop strip product is reduced after excessive water absorption in the using process; the polymethyl methacrylate and the polyurethane resin improve the glass transition temperature of the product, enhance the cohesive strength and surface performance of the product and improve the mechanical strength of the product, and compared with a traditional water stop belt, the expansion rate, the dispersing performance, the water resistance, the mechanical performance, the durability and the glass transition temperature of the water stop belt are improved to a certain extent.
本发明公开了一种异氰酸酯和硅烷偶联剂对膨润土进行改性的止水带，包含以下各成分的重量百分比原料：膨润土40％～60％、改性剂5％～10％、分散剂2％～8％、抗水剂3％～8％、强化剂5％～10％、添加剂10％～25％。本发明采用异氰酸酯和硅烷偶联剂对膨润土进行改性，提高膨润土的膨胀率；烷偶联剂可使膨润土在体系中良好分散；聚烯丙胺解决了膨润土基止水条产品在使用过程中过度吸水后力学性能下降的问题；聚甲基丙烯酸甲酯和聚氨酯树脂，提高了产品的玻璃化转变温度，增强了产品内聚强度和表面性能，提高产品机械强度，相较于传统的止水带，其膨胀率、分散性能、抗水性能、力学性能、耐久性和玻璃化转变温度都有一定的提高。
