1.概述国内外使用的树脂砂浆,胶泥一般都是溶剂型的,所使用的溶剂和硬化剂毒性很大,并有强烈的刺激气味,严重污染环境,并直接危害操作人员的身体健康。为此,我们研究了水乳型环氧树脂,这是一种以水代替有机溶剂、以复合硬化体系代替脂肪族胺类硬化剂的低毒、低污染、节省资源、便于操作的树脂类材料。近年来,美、日等国在环氧树脂的水乳化方面作了研究,他们偏重于水乳化树脂涂料,为提高涂层的耐水、耐腐蚀及抗渗透性,在掺入改性剂方面
1. Overview Resin mortars and cements used at home and abroad are generally solvent-based. The solvents and hardeners used are very toxic, and they have strong irritating odors, which seriously pollute the environment and directly endanger the health of operators. For this purpose, we studied the water-emulsion type epoxy resin, which is a low-toxic, low-pollution, resource-saving, and easy-to-operate resin material that replaces organic solvents with water and replaces aliphatic amine hardeners with a composite hardening system. . In recent years, the United States, Japan, and other countries have conducted studies on the water-emulsification of epoxy resins. They are focusing on water-emulsifying resin coatings. In order to improve the water resistance, corrosion resistance, and permeability of coatings, they are blended with modifiers.
