低温固化的坏氧树脂砂浆,是指能在冰点或冰点以下的温度条件下,可以固化的环氧树脂砂浆。以往,液态环氧树脂在冰点或冰点以下固化的方法,一般采用聚硫醇系、叔胺和水做促进剂的多胺系、三氨化硼和胺的络合物系以及水杨酸为促进剂的多胺系、三氟化硼和胺的络合物系以及水杨酸为促进剂的二胺基二苯基甲烷、二甲苯二胺和有机酸的络合物系、聚异氧酸酯系等等做为固化剂。可是使用这些固化剂,都具有以下缺点:液态树脂和固化剂的混合物粘度大、施工困难,可使用时间短,毒性
Low-temperature curing bad-oxygen resin mortar refers to an epoxy resin mortar that can be cured at a temperature below the freezing point or freezing point. In the past, liquid epoxy resins were solidified below the freezing point or below the freezing point. Generally, polyamine-based, tri-ammonium boronate and amine complexes and poly(salicylic acid) were used as the accelerating agent for polythiol, tertiary amines and water. Accelerator polyamines, complexes of boron trifluoride and amines, and complexes of diaminodiphenylmethane, xylenediamine, and organic acids with salicylic acid as the promoter, polyiso Acid esters and the like are used as curing agents. However, the use of these curing agents all have the following disadvantages: the mixture of the liquid resin and the curing agent has a large viscosity, is difficult to apply, has a short working life, and is toxic.
