摘要
硬脂酸与羟烷基叔胺在催化剂存在下 ,在 1 2 0～ 1 40℃下 ,经 1 5～ 2 0h的反应 ,完成酯化 ,降温至 70～ 60℃ ,加入有机酸 ,形成阳离子物 ,滴加去离子水 ,使产物自乳化 ,制备出稳定的具有蜡感的阳离子型乳液。该乳液与阳离子型成膜材料配合使用 ,进行皮革底涂 ,可防止熨平时粘板 ,并对遮盖伤残有较好的效果。
In the presence of a catalyst, the esterification of stearic acid and hydroxyl alkyltertary amine come to an end after a 15-20?h reaction at 120-140℃, and then it is decreased to a temperature of 70-60?℃, added by an organic acid to form a cationic product, and left the ionic water free for the self-emulsification, followed by the completion of the stable waxy cationic emulsion. The emulsion prevents the board pasting in ironing leathers and impart better defects-covering effects when it is used, in combination with cationic film-forming materials, in the basecoats
