阅读说明：本技术 减少聚氨酯泡沫中醛排放的方法 (Method for reducing aldehyde emissions in polyurethane foams ) 是由 唐铮铭 邹健 冯少光 佐佐木裕司 陈洪亮 李海英 张德刚 张萍 于 2018-08-02 设计创作，主要内容包括：聚氨酯泡沫通过固化含有以下的反应混合物制造：芳香族多异氰酸酯、至少一种平均官能度为至少2并且每个异氰酸酯反应性基团的当量为至少200的异氰酸酯反应性材料、至少一种发泡剂、至少一种表面活性剂和至少一种催化剂、数均分子量为175至450的聚乙烯胺混合物和碱金属、鏻或铵亚硫酸盐。如此生产的泡沫排放低水平的甲醛、乙醛、丙烯醛和丙醛。(Polyurethane foams are made by curing a reaction mixture containing: an aromatic polyisocyanate, at least one isocyanate-reactive material having an average functionality of at least 2 and an equivalent weight per isocyanate-reactive group of at least 200, at least one blowing agent, at least one surfactant and at least one catalyst, a polyvinylamine mixture having a number average molecular weight of 175 to 450, and an alkali metal, phosphonium or ammonium sulfite. The foam so produced emits low levels of formaldehyde, acetaldehyde, acrolein, and propionaldehyde.)
