Polyurethane called poly hydrogen carboxylic acid ester, is a structure containing "NH (, ((), translated JL-island of f. In the 1930 of the 20th century, the DT (hl0 13ayer aims to research and development of a number of potent alcohol addition reaction of the isocyanate route synthesis of polyurethane-Jf.H. In the 1970 of the 20th century, the rapid development of water polyurethane Textile auxiliaries, polyurethane coated fabric has been widely used in a variety of fabrics, channeling interior decoration fabrics and industrial fabrics. 1976 coins only incomplete statistics, European production of polyurethane coated fabric 300 million ~3.5 billion square meters, assuming an average coating 70gimz, consumption of solid polyurethane 0 240,000 tonnes. In the 1980 of the 20th century, the research breakthrough developments and application of polyurethane, water dispersed PU is widely used in textile dyeing and finishing. Europe, America, Japan race to develop, forming many r series-Canton ', such as h-Bayer's impramtl series, Japan Daiichi Pharmaceutical Elastron series. In addition, the United States of DuPont products.
Textile processing building, water dispersed PU research and development and application has been r Pan quickly developed, Torr had the following reasons:
Stream compatibility with a wide range of polyurethane, resin with other water system, such as acrylic, polyvinyl siloxane, amide resin combination to use. Polymer made by polymer blend technology "alloy", can learn from each other and find unexpected synergy effects.
