摘 要:采用聚丙二醇(PPG)、2,2.二羟甲基丙酸(DMPA)和异佛尔酮二异氰酸酯(IPDI)制备聚氨酯(PU)预聚体,甲乙酮肟(MEKO)为封端剂,合成一种封端聚氨酯黏合剂。通过单因素分析试验,优化的合成工艺条件为,R值[n(NCO)/n(OH)]2.4,DMPA用量5%,封端温度40℃,封端时间90min;当黏合剂用量为30%-35%,焙烘温度为125℃,焙烘时间为2.5min时,涂料印花织物的干摩擦牢度达到4级,湿摩擦牢度达到3—4级,皂洗牢度达到3—4级,得色量K/S值9.22,明度L^*35.40。Polyurethane( PU ) is prepared with polypropylene glycol( PPG), dimethylolpropionic acid (DMPA) and isophoronediisocyanate(IPDI) as raw materials, and then is blocked with methyl ethyl ketoxime(MEKO) as a blocking agent. The synthesis conditions are optimized by single factor experiment as follows: R value ( molar ratio of NCO to OH) 2.4, DMPA 5%, and blocking at 40 ℃for 90 min. When the dosage of adhesive is 30%-35%, curing temperature is 125 ℃ and curing time is 2.5 min, the pigment prints feature dry rubbing fastness of Grade 4, wet rubbing fastness of Grade 3-4, soaping fastness of Grade 3- 4, K/S value of 9.22 and the lightness L* of 35.40,as well as good handle.
