| Abstract: | Special requirements for aqueous urethane used in sizing agent for glass fibers are described. In the experiment,di-isocyanate,polyether diol and a hydrophilic chain-extender were used to synthesize aqueous urethane. The effects of some factors such as the synthesizing technology and the dose of hydrophilic chain-extender on the properties of aqueous urethane were studied. It was found that by adjusting these factors,the best combination of hydrophilicity,weak anionic property and film-forming performance of the solution in the use for glass fibers can be achieved. |
