摘　　要：以固体文具胶改性为研究内容,介绍了趣味性和研究型的化学工艺设计实验。采用自制的改性白乳胶为基料,选硬脂酸钠为凝固剂,邻苯二甲酸二丁酯为增塑剂、增韧剂,另加入稀释剂(尿素)、保湿剂(甘油)等,对固体文具胶的配方进行了设计。教学实践表明,该实验激发了学生探索的积极性达到了理想的教学目标。With solid stationery,the gum change sex for study a contents,introduced the chemistry technological design of interest and research type experiment. The adoption was self-made of change sex white the foam rubber anticipate for radicle and choose the stearic acid sodium as coagulant and border on benzene two A sour two D esters in order to increase a Su and a Ren,join another dilution,and hydration,etc.,carried on a design to the formula of the solid stationery gum. The teaching practices enunciation,the experiment stirred up the aggressive that the student investigated to come to an ideal teaching target.
