一种慢回弹材料及制造方法
摘要：
本发明涉及一种聚氨酯材料，尤其是一种慢回弹聚氨酯材料和制造方法，加工时由按照质量百分比计的如下原料制成：高活性端羟基聚醚（FA‑703）40份，高活性接枝聚醚（KGF545）10份，慢回弹聚醚（GLR2000）50份，聚醚改性硅氧烷（DC2525）0.15份，33%三亚乙基二胺溶液（A‑33）1份，二甲基乙醇胺（DMEA）0.5份，催化剂（A‑4）0.5份，聚醚改性硅氧烷（DC2525）0.15份，二乙醇胺（DEOA）1.2份，三乙醇胺（TEOA）0.5份，水（H20）0.8份，一氟二氯乙烷发泡剂（141b）15份，多苯基甲烷多异氰酸酯（SUP‑2412）组成；该材料为解决目前慢回弹材料回弹速度不够慢的问题。
摘要（英）：

The invention relates to a polyurethane material, in particular to a slow-springback material and a production method. During processing, the slow-springback material is made from the following raw materials by mass: 40 parts of high-activity hydroxyl terminated polyether (FA-703), 10 parts of high-activity grafted polyether (KGF545), 50 parts of slow-springback polyether (GLR2000), 0.15 part of polyether modified siloxane (DC2525), 1 part of 33% triethylenediamine solution, 0.5 part of dimethylethanolamine (DMEA), 0.5 part of catalyst (A-4), 0.15 part of polyether modified siloxane (DC2525),1.2 parts of diethanol amine (DEOA), 0.5 part of triethanolamine (TEOA), 0.8 part of water (H2O), 15 parts of dichlorofluoroethane foaming agent (141b) and polyphenylmethane polyisocyanate (SUP-2412).By the polyurethane material, the problem of high springback speed of existing slow-springback materials is solved.
