摘要： Presently, multifunctional carboxylic acids, such as 1,2,3,4-butanetetracarboxylic acid (BTCA) are used to bond a hydroxyl-functional organophosphorous oligomer to cotton fabric in the presence of a catalyst, such as sodium hypophosphite (NaH 2 PO 2 ). However, the free carboxylic acid groups bound to the cotton fabric form a calcium salt during home laundering, thus diminishing the flame retardant properties of the treated cotton fabric. Disclosed herein is a new catalyst system consisting of hypophosphorous acid (H 3 PO 2 ) and a nitrogen-containing organic base such as triethanol amine (TEA). When the catalyst system is present together with the polycarboxylic acid, TEA esterifies the free carboxylic acid groups under curing conditions, thus reducing calcium concentration on the fabric during home laundering. It also provides nitrogen-phosphorous synergism to enhance the flame retardant performance of the organophosphorous compound. The cotton fabric treated with BTCA and the hydroxyl-functional organophosphorous oligomer in the presence of this new catalyst system demonstrate flame retardant properties superior to that treated with NaH 2 PO 2 as a catalyst.
摘要翻译：目前，在诸如次磷酸钠（NaH 2 PO 2）的催化剂存在下，使用多官能羧酸（例如1,2,3,4-丁烷四羧酸（BTCA））将羟基官能的有机磷低聚物与棉织物结合。然而，结合到棉织物的游离羧酸基团在家庭洗涤期间形成钙盐，从而降低了经处理的棉织物的阻燃性能。本文公开了由次磷酸（H3PO2）和含氮有机碱如三乙醇胺（TEA）组成的新型催化剂体系。当催化剂体系与多元羧酸一起存在时，TEA在固化条件下酯化游离羧酸基团，从而在家庭洗涤期间减少织物上的钙浓度。它还提供了氮磷协同作用，以提高有机磷化合物的阻燃性能。在这种新型催化剂体系存在下用BTCA处理的棉织物和羟基官能的有机磷低聚物表现出优于用NaH 2 PO 2作催化剂处理的阻燃性能。
