Embodiment Construction

[0014] An epoxy vegetable oil blended modified pullulan polysaccharide grafted pineapple fiber packaging film, comprising the following components in parts by weight: pineapple leaf fiber 118, composite cellulase 5.5, nano-magnesium oxide particles 2.3, citric acid 4.3, epoxy Vegetable oil 25, pullulan 31, calcium zeolite 9, hydroxypropyl starch 35, hydroxypropyl methylcellulose 4, polyvinyl alcohol 5, konjac glucomannan 9, appropriate amount of water, appropriate amount of deionized water.

[0015] A method for preparing epoxy vegetable oil blended modified pullulan grafted pineapple fiber packaging film, comprising the following steps:

[0016] (1) Dry the pineapple leaf fiber and pulverize it in a universal grinder for 30 minutes into a cotton-like shape, then mix it with citric acid and 4 times the total weight of water to obtain a slurry for use, and heat the slurry to 60°C. And continue to add compound cellulase, mix and stir for enzymolysis for 40 minutes, inactivate th...

Abstract

The invention discloses an epoxy vegetable oil blending modified pullulan grafted pineapple fiber packaging film. The epoxy vegetable oil blending modified pullulan grafted pineapple fiber packaging film is prepared from the following components in parts by weight: 118 to 120 parts of pineapple leaf fibers, 5.5 to 5.8 parts of composite cellulose, 2.3 to 2.5 parts of nano magnesium oxide particles, 4.3 to 4.4 parts of citric acid, 25 to 26 parts of epoxy vegetable oil, 31 to 32 parts of pullulan, 9 to 10 parts of scolecite, 35 to 40 parts of hydroxypropyl starch, 4 to 5 parts of hydroxypropyl methylcellulose, 5 to 6 parts of polyvinyl alcohol, 9 to 10 parts of konjac glucomannan, proper amount of water and proper amount of de-ionized water. A pineapple cellulose film is prepared by combining epoxy vegetable oil blending modified pullulan with a nano-crystallized pineapple leaf cellulose solution and other components and preparing a homogeneous film solution through ultrasonic assisted emulsification and shearing; the pineapple cellulose film is degradable and realizes application of pineapple cellulose and the pullulan to the field of packaging film materials and has good air permeability, spatial structure and stretching-resisting property.

Description

technical field [0001] The invention relates to the technical field of pineapple leaf fiber packaging film, in particular to an epoxy vegetable oil blended modified pullulan polysaccharide grafted pineapple fiber packaging film and a preparation method thereof. Background technique [0002] Using cellulose as a raw material, the preparation of polymer membrane materials with different properties plays an important role in the fields of medicine, biology, food and medicine, and has become a current research hotspot. my country produces a large number of pineapples every year. Pineapple leaf fiber has health effects such as antibacterial and deodorizing. The use of pineapple leaf fiber to prepare polymer membrane materials has great development prospects. The fiber macromolecules of the pineapple leaf fiber crystalline koji are arranged neatly and regularly, and the polyhydroxy structure and strong hydrogen bonding of the fiber molecules make it have a high degree of cleanline...
