An adhesive composition comprising either (i) a latex polymer having a Tg from -10°C to 25°C or (ii) a mixture of soft latex polymer and hard latex polymer, each polymer being either
(1) a copolymer of quaternary monomer prepared by reacting an epihalohydrin of the formula XCH2-CHCH2O with a salt of an amine of the formula RN(R')CH3, or
(2) A reaction product of a copolymer of such an amine salt and such an epihalohydrin;
wherein
R is an ethylenically unsaturated organic group,
R' is a linear (C, to C4)-alkyl group, optionally hydroxy-substituted,
X is chlorine, bromine or iodine.
The compositions are useful in bonding a flexible covering layer, such as fabric covered polyurethane foam, to a rigid substrate such as glass fibre mat to produce laminates including automotive headliners and acoustic panels.
一种粘合剂组合物,包括(i)Tg 为 -10°C 至 25°C 的乳胶聚合物或(ii)软质乳胶聚合物和硬质乳胶聚合物的混合物,每种聚合物都是
(1) 由式 XCH2-CHCH2O 的表卤代烃与式 RN(R')
CH3 的胺盐反应制备的季单体共聚物,或
(2) 此类胺盐与此类表卤代烃的共聚物的反应产物;
其中
R 是
乙烯基不饱和有机基团、
R' 是线性(C,至 C4)烷基,可选择羟基取代、
X 是
氯、
溴或
碘。
这些组合物适用于将织物包覆聚
氨酯泡沫等柔性覆盖层粘合到
玻璃纤维毡等刚性基材上,以生产包括汽车顶篷和隔音板在内的层压板。
