新溶剂体系应用研究（二）在常温干燥双组分聚氨酯涂料稀释剂体系的应用研究

摘要

新溶剂体系是指由乙酸仲丁酯、甲氧基乙酸甲酯、甲氧基乙酸仲丁酯、聚酯油构成的溶剂体系，本文以这些新产品溶剂为对象，在常温干燥环境下的双纽分聚氨酯涂料中予以应用，考察溶剂的稀释剂性能，进行对比研究、%A new solvent system is composed of sec-butyl acetate, methyl methoxy acetate, methoxy butyl acetate and polyester oil. The common characteristics include low- toxicity or non-toxicity, new synthetic technology, low second pollution and high price/performance ratio. The paper also introduces the application results of the new solvent system in ambient dry tow- component polyurethane coatings thinner system. The contrast test between the new solvent system with the present solvents based oil benzene, xylene, propylene glycol monomethyl ether acetate and cyclohexanone etc. is also made.
