Abstract

The structure of an active diluent influences the rheological properties of epoxy compounds. The use of a linear alkyl glycidyl ether allows preparation of compounds with the lowest dynamic viscosity. As the active diluent content is increased from 0 to 20%, the period in which the network polymer is formed in the course of curing of epoxy compounds increases from 5 to 30 min because of a decrease in the rate of consumption of epoxy groups in the compound with an increase in the active diluent content. The elastic-strain and thermal properties of epoxy polymer films were studied. When using a linear alkyl glycidyl ether as an active diluent, the ultimate strength and glass transition temperature as functions of the diluent content pass through a minimum. Introduction of monofunctional active diluents into the compound leads to a decrease in the elastic modulus. An increase in their content in the compound from 5 to 20% does not affect the elastic modulus.

活性稀释剂对基于它们的环氧化合物和涂料性能的影响

摘要

活性稀释剂的结构会影响环氧化合物的流变性。线性烷基缩水甘油醚的使用允许制备具有最低动态粘度的化合物。随着活性稀释剂含量从0％增加到20％，在环氧化合物固化过程中形成网络聚合物的时间从5分钟增加到30分钟，这是因为降低了环氧树脂中环氧基的消耗速率。活性稀释剂含量增加的化合物。研究了环氧聚合物薄膜的弹性应变和热性能。当使用直链烷基缩水甘油醚作为活性稀释剂时，极限强度和玻璃化转变温度随稀释剂含量而变小。将单官能活性稀释剂引入化合物中导致弹性模量降低。它们在混合物中的含量从5％增加到20％不会影响弹性模量。
