    • Thermoplastic polyurethane is provided to prevent the fire due to high oxygen index, and to reduce the generation of noxious gas because a halogen element is not contained, while having the self-extinguish stability after firing. Flame retardant characteristic thermoplastic polyurethane comprises organic diisocyanates, Long-chain diols, a chain extender, and a mixture of melaminecyanurate and phosphinate indicated as the chemical formula 1 as a flame retardant. The melaminecyanurate is contained in the amount more than 25 parts by weight, based on the solid content 100 parts by weight of thermoplastic polyurethane. In the chemical formula 1, R1 and R2 are the same or different, show C1-6 linear or branched alkyl or aryl group; M is calcium, aluminium or zinc ion; and m is 2 or 3.
    • 提供热塑性聚氨酯以防止由于氧指数高引起的火灾,并且由于不含有卤素元素而在烧制后具有自熄性稳定性,因此可减少有害气体的产生。 阻燃特性的热塑性聚氨酯包括有机二异氰酸酯,长链二醇,扩链剂,和作为阻燃剂的化学式1表示的三聚氰胺氰尿酸酯和次膦酸酯的混合物。 基于固体含量为100重量份的热塑性聚氨酯,所述三聚氰胺氰尿酸酯的含量为25重量份以上。 在化学式1中,R 1和R 2相同或不同,表示C 1-6直链或支链烷基或芳基; M是钙,铝或锌离子; m为2或3。

    • PURPOSE: A method for preparing an antibacterial polyurethane foam is provided, to improve the antibacterial effect of a polyurethane foam by injecting an antibacterial component into the polyurethane foam without additional post-treatment and drying process. CONSTITUTION: The method comprises the steps of (100) preparing polyol; (102) preparing a slurry-type inorganic antibacterial agent; (104) mixing the polyol and the inorganic antibacterial agent; and mixing the mixture solution, polyisocyanate, a stabilizer and an additive, (106) foaming the obtained mixture and curing it. Preferably the polyol is a polyether-based polyol, and more preferably is polypropyl glycol. The inorganic antibacterial agent comprises XM(2/n)O·Al2O 3·YSiO2·ZH2O, wherein M is an ion such as Ag and Na, X is 2, Y is 3, Z is 1 and n is an integer.
    • 目的:提供一种用于制备抗菌聚氨酯泡沫的方法,以通过将抗菌组分注入聚氨酯泡沫中而无需额外的后处理和干燥过程来提高聚氨酯泡沫的抗菌效果。 构成:该方法包括步骤(100)制备多元醇; (102)制备浆料型无机抗菌剂; (104)混合多元醇和无机抗菌剂; 混合该混合溶液,多异氰酸酯,稳定剂和添加剂,(106)使所得混合物发泡并固化。 优选多元醇是聚醚基多元醇,更优选聚丙二醇。 无机抗菌剂包括XM(2 / n)O< Al 2 O 3· YSiO 2< Z 2 O,其中M是离子如Ag和Na,X是2,Y是3,Z是1,n 是一个整数。
