摘要: The present invention discloses a biodegradable polyester composition, wherein based on a total weight of the biodegradable polyester composition, a weight content of a cyclic ester compound having a structure shown as formula (I) is 100ppm-950ppm;
In the present invention, by adding the the cyclic ester compound into the composition and controlling the content of the cyclic ester compound in a range of 100ppm-950ppm, an anti-thermal oxidative aging property of the biodegradable polyester composition is greatly enhanced. In addition, after being digested with 95% ethanol at 40°C for 240 hours, a film prepared by blow molding or a part prepared by injection molding has little precipitate separating out of the surface and has an excellent surface appearance property.摘要翻译: 本发明公开了一种生物可降解聚酯组合物,其中基于生物可降解聚酯组合物的总重量,具有式(I)所示结构的环状酯化合物的重量含量为100ppm-950ppm; 在本发明中,通过将环状酯化合物添加到组合物中并且将环状酯化合物的含量控制在100ppm-950ppm的范围内,可生物降解的聚酯组合物的抗热氧化老化性能大大提高。 此外,用95%乙醇在40℃下消化240小时后,通过吹塑或通过注塑制备的部件制备的膜几乎没有从表面析出的沉淀,并具有优异的表面外观性能。

摘要: The present invention discloses a biodegradable polyester composition, wherein based on a total weight of the biodegradable polyester composition, a weight content of cyclopentanone is 0.5ppm-85ppm. In the present invention, by adding cyclopentanone into the composition and controlling the content of cyclopentanone in the composition within a range of 0.5ppm-85ppm, a lubrication degree of a film of biodegradable polyester during a blow molding process can be improved. When a velocity of film blowing is 176 Kg/h, a range of a film thickness is less than 0.2µm and a relative deviation of the film thickness is less than 1%. Bubble stability and continuity of film blowing are guaranteed.
