Embodiment 1

[0024] Embodiment 1: In this embodiment, the medicinal dregs of the sesame root are taken as an example to prepare a high-toughness nanocellulose / plastic composite material of traditional Chinese medicine dregs, and proceed as follows:

[0025] (1) Pulverize a certain amount of sesame root medicinal residues, use ethanol:toluene according to the volume ratio of 1:2 to form a mixed solution, after mixing with a material-liquid ratio of 1:20 (mass ratio), in a Soxhlet extractor Extraction treatment was carried out at 120°C for 48 hours.

[0026] (2) The product obtained in step 1 was subjected to vacuum filtration, and the filter residue was naturally dried in a fume hood for 24 hours.

[0027] (3) Disperse the filter residue treated in step 2 in an aqueous potassium hydroxide solution with a concentration of 3 wt%, with a solid-to-liquid ratio of 1:50 (mass ratio); stir and react for 2 hours in a water bath at 90°C. After the reaction is finished, vacuum suction filtration is ...

Embodiment 2

[0042] Embodiment 2: In this embodiment, taking the Chinese medicine dregs of Dioscorea florida as an example, the high-toughness Chinese medicine dregs nanocellulose / plastic composite material is prepared, and the steps are as follows:

[0043] (1) Grinding the traditional Chinese medicine dregs of Dioscorea floridae with ethanol: toluene mixture solution with a volume ratio of 1:2, and a solid-liquid ratio of 1:20 (mass ratio) for 48 hours of extraction treatment at 120°C.

[0044] (2) The product obtained in step 1 was taken out, and the traditional Chinese medicine residue of Dioscorea florida was taken out, placed in a petri dish, and dried naturally in a fume hood for 24 hours.

[0045] (3) Put the dregs extracted by ethanol and toluene into a continuous steam explosion machine for 6 minutes at 200° C. and 1.5 MPa for steam explosion.

[0046] (4) Disperse the filter residue treated in step 3 in an aqueous potassium hydroxide solution with a concentration of 3 wt%, with ...

Abstract

The invention discloses a method for manufacturing a high-toughness traditional Chinese medicine residue / plastic composite material. According to the method, the high-toughness traditional Chinese medicine residue / plastic composite material is manufactured through a step of extraction processing through a traditional Chinese medicine residue chemical method and steam explosion pretreatment and a step of mixing of nano-fibers prepared from the traditional Chinese medicine residue and thermoplastic plastics. Through the composite material, material performances such as plasticization and stretch enhancement effects are improved. The physical modification of medicine residue cellulose does not lead to environmental pollution, and the resource utilization rate is improved.

Description

technical field [0001] This technology relates to the synthesis of plant fiber plastic composite materials, in particular to a preparation method of high-toughness traditional Chinese medicine dregs / plastic composite materials, using nanofibers transformed from waste dregs and plastic composite materials to prepare polymer composite materials, improving the original nature. Background technique [0002] At present, composite materials are widely used in people's life. The matrix materials of composite materials are divided into two categories: metal and non-metal. Commonly used metal substrates are aluminum, magnesium, copper, titanium and their alloys. Non-metallic substrates mainly include synthetic resin, rubber, ceramics, graphite, carbon, etc. Among them, the wood-plastic composite material is an organic combination of plant fibers and plastics, and has the characteristics of both plant fibers and plastics, effectively meeting the material needs of related fields. W...
