| titleOfInvention | A kind of method being prepared regenerated cellulose film by cellulose carbamate |
| abstract | The invention discloses a kind of method directly being prepared regenerated cellulose film by cellulose carbamate.Cellulose carbamate is scattered in the aqueous solution of sodium hydroxide/0.1 ~ 3 wt% zinc oxide of 6 ~ 10 wt% by the method, less than-10 DEG C are refrigerated under cold condition, taking out thaws under not higher than the condition of 50 DEG C prepares the cellulose carbamate solution of high stability, curtain coating knifing after deaeration, in precipitation bath, direct solidification forming just prepares the low regenerated cellulose film of residual nitrogen quantity.This film has good mechanical property and transmittance, the method can remove the process of saponification in the basic solutions such as NaOH, regeneration from, its production process nontoxic pollution-free, is expected to replace with serious pollution viscose process and produces glassine paper technique, and have the prospect of significantly application. |
