Abstract: the invention relates to the invention. Textile coatings In the field of technology, a self repairing polyurethane emulsion is disclosed. Self repairing polyurethane is a hydrophilic block composed of a fixed phase and a reversible phase. polyurethane The molecular weight is 10000~50000, of which the stationary phase is higher than 100 degrees. Glass The temperature of transformation or crystallization is reversible, and the reversible phase has a temperature of -10 ~ 60 DEG.

The polyurethane emulsion can be made into textile printing coatings. The self repairing of printing coatings is less than 5mm, the deformation fixing rate is less than 30%, the recovery rate of deformation is more than 90%, and the recovery temperature range of the reversible phase is -10 ~ 60 C.

The general office of the State Council recently issued the "guiding opinions on further promoting the pilot work of paid use and trading of emission rights" (hereinafter referred to as the "opinions"), and deployed to give full play to the role of the market mechanism in environmental protection and pollutant emission reduction, and to promote the continuous and effective reduction of the total discharge of major pollutants. It is proposed that the pilot areas in 2015 will fully complete the emission rights approval of the existing pollutant discharge units before the end of 2015, and basically establish a paid use and trading system of emission permits by the end of 2017, laying the foundation for the full implementation of the paid use and trading system of emission permits.

Insiders said in an interview with reporters, "at present, many textile and industrial cities and counties in Jiangsu and Zhejiang have launched the emission trading. Now the State Council has issued the "opinions", and once again made clear the time requirements for the pilot tasks.
