TDI 的中文全称是甲苯二异氰酸酯,无色至淡黄色液体,有强烈的刺激气味,有毒。溶于乙醚、丙酮和某些其他有机溶剂。与水作用发生二氧化碳,与二元醇作用而成线性聚氨基甲酸酯和聚氯酯树脂。TDI 是一种混合型的异氰酸酯。聚氨酯工业常用的 TDI 是2,4-TDI 和2,6-TDI 两种异构体质量比为80:20的混合物,目前90%以上的 TDI用于聚氨酯软泡的生产,少量用作聚氨酯硬泡、聚氨酯系列胶粘剂/密封剂、聚氨酯系列涂料和聚氨酯弹性体的中间体。聚氨酯被世界化工界视为
TDI Chinese name is toluene diisocyanate, colorless to pale yellow liquid, a strong stimulating odor, toxic. Soluble ether, acetone and some other organic solvents. The role of carbon dioxide and water, and the role of glycol made of linear polyurethane and polyurethane resin. TDI is a mixed isocyanate. TDI commonly used in the polyurethane industry is a mixture of two isomers of 2,4-TDI and 2,6-TDI in a mass ratio of 80:20. At present, more than 90% of TDI is used for the production of polyurethane flexible foam and a small amount is used as a polyurethane hard Foam, polyurethane series of adhesives / sealants, polyurethane coatings and polyurethane elastomer intermediates. Polyurethane is regarded by the world chemical industry
