摘要
以果糖代替甲醛,在酸性条件下合成了果糖缩二脲树脂胶粘剂,并通过正交实验法获得了该树脂合成的最佳反应条件:n(果糖)∶n(缩二脲)=6∶1,催化剂用量为0.4%,反应温度为100℃,反应时间为2.5 h;同时对树脂的固化条件也进行了优选,最佳固化温度为120℃,固化剂用量为8%,固化时间为2 h。
In acidic condition,fructose-diurea resin adhesive by using fructose instead of formaldehyde was prepared successfully. And through orthogonal experiments the optimum conditions of the reaction were gained： molar ration of fructose to diurea is 6：1 ,the content of catalyst was 0.4% （percent of the weight of fructose） ,reaction temperature is 100 ℃ andreaction time is 2.5 h. With phthalic anhydride as curing agent,the optimum curing temperature is 120℃,the mass ratio of the curing agent is 8% and curing time is 2 h.
