Embodiment 1

[0043] Compatibilizer used in the present invention is produced by French Akema company, and the trade mark is 3210. The chain extender is produced by BASF, Germany, and the brand name is Joncyl AR-4370.

[0044] Mix 0.3 parts of chain extender, 0.8 parts of anti-blocking agent and other powders with 20 parts of block-type poly 3-hydroxybutyrate-block-poly 4-hydroxybutyric acid (P3HB-b -P4HB) Stir fully in a bread machine for 20 minutes. Meanwhile, mix 2 parts of compatibilizer with 80 parts of PBAT ( F C-1200) for mixing. After mixing evenly, feed to the extruder with a speed of 336g / hr and 1344g / hr through a powder feeder and a pellet feeder respectively. Extruded and granulated by PolyLab HAAKE Rheomex OS PTW16 co-rotating twin-screw extruder (screw diameter 16mm, L / D=40) of American Thermo-Fisher Technology Company. The extruder has 11 sections from the feed port to the die, numbered 1-11, and the first section only plays the role of feeding and cannot be heated. T...

Embodiment 2

[0046] Mix 0.3 parts of chain extender, 0.8 parts of anti-blocking agent and other powders in proportion with 25 parts of block-type poly 3-hydroxybutyrate-block-poly 4-hydroxybutyric acid (P3HB- b-P4HB) Fully stir and mix in the bread machine, and the stirring time is 20min. Meanwhile, mix 2 parts of compatibilizer with 75 parts of PBAT ( F C-1200) for mixing. After mixing evenly, feed at a rate of 630g / hr and 1470g / hr through a powder feeder and a pellet feeder, respectively. Extrude and granulate through PolyLab HAAKE Rheomex OS PTW16 co-rotating twin-screw extruder (screw diameter: 16mm, L / D=40) from American Thermo Fisher Technology Company. The extruder has 11 sections from the feed port to the die, numbered 1-11, and the first section only plays the role of feeding and cannot be heated. The temperatures of sections 2-11 of the extruder are respectively: 150°C, 160°C, 160°C, 160°C, 165°C, 165°C, 165°C, 165°C, 170°C and 160°C, and the screw speed is set at 200 rpm. D...

Embodiment 3

[0048] Mix 0.3 parts of chain extender, 0.8 parts of anti-blocking agent and other powders in proportion with 60 parts of block-type poly 3-hydroxybutyrate-block-poly 4-hydroxybutyric acid (P3HB- b-P4HB) Fully stir and mix in the bread machine, and the stirring time is 20min. Meanwhile, mix 2 parts of compatibilizer with 40 parts of PBAT ( F C-1200) for mixing. After mixing evenly, feed at a rate of 1368g / hr and 912g / hr through a powder feeder and a pellet feeder, respectively. Extrude and granulate through PolyLab HAAKE Rheomex OS PTW16 co-rotating twin-screw extruder (screw diameter: 16mm, L / D=40) from American Thermo Fisher Technology Company. The extruder has 11 sections from the feed port to the die, numbered 1-11, and the first section only plays the role of feeding and cannot be heated. The temperatures of sections 2-11 of the extruder are respectively: 150°C, 160°C, 160°C, 160°C, 165°C, 165°C, 165°C, 165°C, 170°C and 160°C, and the screw speed is set at 200 rpm. D...

Abstract

The invention relates to a polyhydroxyalkanoate blend with high melt strength and a film, and preparation methods and applications thereof, and mainly solves the problems that biosynthetic polyester melt is low in strength, easy to snap in the film forming process and difficult to blow-mold. The polyhydroxyalkanoate blend comprises the following components in parts by mass: (1) 10-80 parts of polyhydroxyalkanoate; (2) 90-20 parts of polyadipic acid / butylene terephthalate; and (3) 0.1-5 parts of a processing aid. According to the technical scheme, the problems are well solved, and the polyhydroxyalkanoate blend can be applied to industrial production of polyhydroxyalkanoate blend materials and films with high melt strength.

Description

technical field [0001] The invention belongs to the field of bio-based and biodegradable compositions, and specifically relates to a high-melt-strength polyhydroxyalkanoate blend and film as well as its preparation method and application. [0002] technical background [0003] Plastic has the advantages of easy processing, low cost, product strength, and good flexibility, and has become a necessary product that is difficult to replace in the industry and daily use fields in contemporary society. However, due to the stable molecular structure of commonly used plastics, they have strong resistance to natural environmental factors such as light, moisture, and oxygen, and are difficult to degrade in many cases. After plastic is used, it is discarded in the environment, causing serious environmental ecological pollution such as land and water. Biodegradable plastics can eventually decompose into carbon dioxide and water under natural conditions. Therefore, the development of hig...
