一种复合热封胶及其制备方法
摘要：
一种复合热封胶及其制备方法，其特征在于由下列重量份的原料制成：对苯二甲酸二甲酯12-14、聚甘油脂肪酸酯8-9、二异丙基萘磺酸钠2-3、聚丙二醇甘油醚4-6、苯基三氯硅烷3-5、丙烯腈4-6、妥儿油酸1-2、苯基三乙氧基硅烷2-3、过氧化苯甲酸叔丁酯1-2、乙酸乙酯15-18、丙二醇3-5、增粘助剂4-5。本发明的热封胶可以粘接纸塑、塑铁等，具有良好的水密性和力学性能、低温热封性，起封温度为105℃，且热封剪切强度达到12Mpa，可以用于印铁罐口塑封粘接，效果好。
摘要（英）：

The invention discloses composite heat-sealing glue and a preparation method thereof. The composite heat-sealing glue is prepared from 12-14 parts by weight of dimethyl terephthalate, 8-9 parts by weight of polyglycerol fatty acid ester, 2-3 parts by weight of sodium diisopropyl naphthalenesulfonate, 4-6 parts by weight of polypropylenglycol diglycidyl ether, 3-5 parts by weight of phenyltrichlorosilane, 4-6 parts by weight of acrylonitrile, 1-2 parts by weight of tall oil fatty acid, 2-3 parts by weight of phenyltriethoxysilane, 1-2 parts by weight of tert-butyl peroxybenzoate, 15-18 parts by weight of ethyl acetate, 3-5 parts by weight of propylene glycol and 4-5 parts by weight of a tackifying promoter. The composite heat-sealing glue can be used for bonding paper plastic and plastic iron, has good watertightness, mechanical properties, low-temperature heat sealability, a sealing-starting temperature of 105 DEG C and heat-sealing shear strength of 12MPa, can be used for plastic package bonding of a metal decorating tank opening and has good effects.
