| titleOfInvention | A kind of narrow distribution full bio-based PBSA biodegradable plastic and preparation method thereof |
| abstract | The invention discloses a preparation method of a narrow distribution full bio-based PBSA biodegradable resin, comprising the following steps: (1) adding raw materials bio-based succinic acid, bio-based adipic acid, bio-based butanediol and a composite catalyst into In a nitrogen-protected reaction vessel; (2) the reaction system is heated to 80～120 ℃ in a temperature-programmed mode, and beating for 15～30 minutes; (3) the reaction system is heated to 180～240 ℃ by a temperature-programmed mode again, keeping The temperature is 1 to 4 hours; (4) the system after the esterification stage is evacuated to between 1000 to 10000 Pa, and kept at 180 to 240 ° C for 30 to 120 minutes; (5) at 180 to 240 ° C, the system is evacuated To below 80Pa, continue to react for 60-300 minutes to obtain the product. The PBSA biodegradable resin prepared by the method of the invention has excellent performance, effectively solves the problems of poor production stability and high cost in the prior art, and conforms to the concept of sustainable development and green environmental protection. |
