一种水性聚氨酯胶粘剂
摘要：
本发明公开了一种水性聚氨酯胶粘剂，制备原料以重量份数计，包括：聚环氧丙烷醚二醇（PPG2000）1~10份、聚己二酸丁二醇酯（PBA）1~10份、异佛尔酮二异氰酸酯（IPDI）5~10份、2,2-二羟甲基丙酸（DMPA）2~10份、2,2-二甲基三亚甲基环碳酸酯（PDTC）2~10份、4-氨基苯磺酸钠（SABS）5~10份、三乙胺（TEA）1~5份、KH570硅烷偶联剂5~10份、纳米氢氧化铝1~10份、无水乙醇20~30份以及蒸馏水为20~57份。本发明还公开了聚氨酯胶粘剂的制备方法。采用本发明所制备的胶粘剂，应用于纺织领域中，可赋予纺织品优异的阻燃性和力学性能，而且耐溶剂性好、绿色环保、粘结强度高，对绒毛、布料具有良好的粘结力。另外，具有较好的稳定性，储存期长，常温密封储存可超过1年以上。
摘要（英）：

The invention discloses an aqueous polyurethane adhesive. The aqueous polyurethane adhesive is prepared from raw materials in parts by weight as follows: 1-10 parts of polypropylene glycol (PPG 2000),1-10 parts of PBA (polybutylene adipate), 5-10 parts of IPDI (isophorone diisocyanate), 2-10 parts of DMPA (2,2-bis(hydroxymethyl)propionic acid), 2-10 parts of PDTC (2,2-dimethyltrimethylene carbonate), 5-10 parts of SABS (4-amino-benzenesulfonic acid monosodium salt), 1-5 parts of TEA (triethylamine), 5-10 parts of a KH570 silane coupling agent, 1-10 parts of nano aluminum hydroxide, 20-30 parts of absolute ethanol and 20-57 parts of distilled water. The invention further discloses a preparation method of the polyurethane adhesive. The adhesive is applied to the textile field, can endow textiles with excellent flame retardancy and mechanical properties, has good solvent resistance, is green and environmentally friendly, has high bonding strength, and has good bonding force on fluff andcloth. Besides, the adhesive has good stability, long storage period, and can be sealed for storage at room temperature for 1 year or longer.
