上海染化十厂经反复试验和不断的实践,在玻璃钢防蚀衬里施工工艺技术中,广泛使用环氧-酚醛混合树脂,以代替过去传统使用的纯环氧树脂,获得了较纯环氧树脂更佳的防蚀效果。该厂的实践表明,当采用E-44刑环氧树脂和~#2130型酚醛树脂,按其重量比各为1比1进行物理性混合后,在常温条件下,仍可使用环氧树脂常用的常温固化剂(如乙二胺、间苯二胺、苯二甲胺、多乙烯多胺等)予以固化。采用上述环氧-酚醛树脂所制得的玻璃钢,较纯环氧树脂的韧性约提高40%,抗拉
After repeated experiments and continuous practice, Shanghai Dyeing and Ten Chemicals Factory made extensive use of epoxy-phenolic mixed resin in the construction technology of FRP lining, instead of the pure epoxy resin used in the past and obtained relatively pure epoxy resin Better anti-corrosion effect. The plant’s practice shows that when using E-44 Penalty epoxy resin and # 2130-type phenolic resin, according to their weight ratio of 1 to 1 for physical mixing, at room temperature, can still be used epoxy resin commonly used Of room temperature curing agent (such as ethylenediamine, m-phenylenediamine, xylylenediamine, polyethylene polyamine, etc.) to be cured. FRP made using the above-mentioned epoxy resin, the toughness of pure epoxy resin increased by about 40%, tensile
