Preparation of Modified Cornstarch Adhesive for Bonding Wood

木材用改性淀粉胶黏剂的制备


以玉米淀粉、三聚氰胺、尿素和甲醛为原料,利用交联共聚的方法,制备木材用改性淀粉胶黏剂。分别研究配比中三聚氰胺、尿素和甲醛对改性后的淀粉胶黏剂干状胶合强度、湿状胶合强度和游离甲醛含量3个性能指标的影响。利用傅里叶转换红外光谱技术对其结构进行表征。

The starch adhesive modified with melamine, urea and formaldehyde is prepared and studied in this paper, based on the theory of cross-linking reaction and copolymerization. The impact of melamine, urea and formaldehyde on the performances of dry bond strength and wet bond strength is expounded by a series of experiments. At last, the structural performance of the modified cornstarch adhesive is elucidated with fourier transform infrared spectroscopy (FTIR).
