CN109081896A 一种结构抗菌型聚氨酯软泡材料及其制备方法 无效 - 驳回

一种结构抗菌型聚氨酯软泡材料及其制备方法
摘要：
本发明公开了一种结构抗菌型聚氨酯软泡材料的制备方法，首先按照质量比称取结构抗菌型的纯水性纳米含氟多元醇、高活性聚醚多元醇330N和聚醚多元醇WANOL F3156，将其置于反应容器中，再按一定重量份数加入含胍盐酸盐扩链剂、催化剂和匀泡剂，快速搅拌均匀构成A组分。再以异氰酸酯为B组分，二者快速混合均匀后倾入模具中发泡，即可得到结构抗菌型聚氨酯软泡材料。抗菌性能测试结果表明，所得结构抗菌型聚氨酯软泡材料对大肠杆菌和金黄色葡萄球菌的抗菌率均≥99.0%，呈现出优异的抑菌性能。
摘要（英）：

The invention discloses a preparation method of a structural antibacterial polyurethane flexible foam material. The preparation method includes: weighing structural antibacterial pure-water nano fluorine-bearing polyol, high-activity polyether polyol 330N and polyether polyol WANOL F3156, adding them into a reaction container, adding certain parts by weight of guanidine-bearing hydrochloride chainextender, catalyst and foam stabilizer, and stirring well fast to form component A; using an isocyanate as component B, mixing well quickly the components A and B, pouring the mixture into a mold, and foaming to obtain the structural antibacterial polyurethane flexible foam material. Antibacterial performance test results show that the structural antibacterial polyurethane flexible foam materialhas antibacterial rate of >/=99.0% for both Escherichia coli and Staphylococcus aureus, and has excellent antibacterial performance.
