Problems solved by technology

PBAT has good ductility and elongation at break, and it also has a certain strength after forming a film, but because PBAT increases the shear strength during processing when it is filled with mineral powder, the small molecules contain

Example Embodiment

[0054] Example 1

[0055] (1) preparing a metal organic framework (MOF)

[0056] Zirconium dichloride was weighed 100g and 100g of the 2- amino acid added to the flask was added 300mL N'N-dimethylformamide, was added 40mL of deionized water with stirring was transferred to a Teflon-liner was sufficiently of the autoclave, the reaction 36h at 150 ℃. After the reactor was cooled naturally, the product was added in 300mL N'N-dimethylformamide, ultrasonic washing for 10 minutes and transferred to a rotary evaporator to dryness 80 ℃. Yellow powder was obtained, in by suction filtration apparatus were washed three times with methanol, placed in an oven dried 100 deg.] C.

[0057] (2) Preparation of modified metal organic frameworks (M-MOF)

[0058] Weighed 100g step metal organic frameworks (1) prepared was added with 150g KH-560 three-necked flask, was added 300mL N'N-dimethylformamide, stirred well, the reaction in an oil bath at 150 ℃ 8h. After spin evaporated natural cooling, the res...

Abstract

The invention discloses a degradable PBAT composite film and a preparation method thereof. The degradable PBAT composite film comprises PBAT, a modified metal organic framework, talcum powder, a chain extender and a slipping agent. According to the invention, a coupling agent is adopted to modify the metal organic framework, so the metal organic framework has the functions of adsorbing micromolecules and removing odor, and also can be uniformly dispersed in PBAT together with filler; and the prepared PBAT composite film is easy to process, uniform in dispersion, low in odor and high in performance, and can be used in film packaging materials requiring low odor, such as supermarket vest bags, food packaging bags and the like.

Description

technical field [0001] The invention belongs to the field of degradable materials, in particular to a low-odor biodegradable PBAT composite film and a preparation method thereof. Background technique [0002] With the development of the national economy and the rise of the Internet economy, the consumption of plastic products is also increasing. Among them, the use of plastic packaging in the express delivery industry, such as bubble film and bubble bags, is also increasing simultaneously. Although recycling, crushing, and reuse are currently used to reduce plastic waste, thereby slowing down white pollution, this method is a temporary solution, not a permanent cure. With the implementation of the plastic ban, industries such as express delivery have also begun to seek alternative solutions in advance. Degradable resins have attracted the attention of many researchers and companies due to their degradation characteristics. [0003] Polybutylene terephthalate / adipate (PBAT) ...
