| titleOfInvention | A kind of ageing-resistant polyester modification material |
| abstract | The invention provides a kind of ageing-resistant polyester modification material, the raw material composed as follows by quality is made: polyester 80% ~ 99.7%, the poly-dihydric alcohol 0.1% ~ 10% of terminal functionality, the polycarbodiimide 0.1% ~ 5% of monoalkoxy polyethylene glycol or polypropylene glycol modified, auxiliary agent 0.1% ~ 5%; The present invention prepare polyester modification material or the finished product be made up of it compared with existing known technology, there is preferably hydrolysis characteristic, before the ageing-resistant test of polyester material, end carboxyl group content is at 0 ~ 20eq/t, after ageing-resistant process, the extension at break conservation rate of polyester is still higher, and other performance of polyester is also more satisfactory; And the gas do not produced in process of manufacture human health, also can not increase melt viscosity and cause processing difficulties, also finds no lower-molecular substance and move the problem of oozing out in goods use procedure. |
