实验是以多种聚酯多元醇(PE)、4,4-二苯基甲烷二异氰酸酯(MDI)、乙二醇(EG)1,4-丁二醇(BG)等原料合成湿式聚氨酯树脂,考察了PE、EG、BG对树脂凝固时间、成肌性、凝聚界的影响。
The experiment is based on a variety of polyester polyol (PE), 4,4-diphenylmethane diisocyanate (MDI), ethylene glycol (EG) 1,4-butanediol (BG) and other raw materials to synthesize wet polyurethane resin, The effects of PE, EG, BG on the resin solidification time, myogenic and cohesive boundary were investigated.
