Embodiment Construction

[0010] The production method of degradable antistatic film comprises the following process steps: Carboxylate carbon nanotube CNTs first, then prepare PLA / PBAT / CNTs-COOH composite material by melt blending method, wherein, the addition amount of CNTs-COOH is 1.2wt%, and finally prepare the composite material into a degradable antistatic film by blow molding.

[0011] The specific production process is: Carboxylate the carbon nanotubes CNTs first, then put the PLA and PBAT particles in a vacuum oven, dry them for 3.5 hours at 85°C, add the dried PLA, PBAT and CNTs-COOH into the In the internal mixer, 175 ° C, 60 rpm, melting and banburying for 5 minutes to obtain PLA / PBAT / CNTs-COOH composite materials, wherein the ratio of PLA and PBAT is 7:3, CNTs-COOH is in PLA / PBAT / CNTs- The amount of COOH composite material is 0.8wt%-1.4wt%, wherein, the process of carboxylation of the carbon nanotube CNTs is: put 2gCNTs into the mixed liquid of 82ml concentrated nitric acid and concentrate...

Abstract

The invention discloses a production method of degradable antistatic film, comprising the steps of subjecting CNTs (carbon nanotubes) to carboxylation, preparing PLA / PBAT / CNTs-COOH composite by melting and co-blending, and preparing degradable antistatic film with the composite by means of blow molding. The degradable antistatic film, as a packaging material, is given good antistatic and mechanical properties and good comprehensive performance through nano material modifications; the production method is simple; the degradable antistatic film has good application value; especially as CNTs-COOHis introduced to a PLA / PBAT system, it is possible to effectively improve impact strength and reduced surface resistivity without decreasing tensile strength; the degradable antistatic film is suitable for antistatic packaging of static sensitivity products, is environmentally friendly and degradable and is worthy of popularization.
