Embodiment 1

[0038] A kind of licorice dregs reinforced recycled polyethylene composite material is prepared according to the following steps:

[0039] (1) Pretreatment of licorice residue

[0040] The licorice residue was pretreated by steam explosion method. First, pick the licorice dregs, remove impurities, put them into a crusher and crush them into coarsely broken licorice dregs; secondly, soak the above broken licorice dregs in 0.5 mol / L sodium hydroxide aqueous solution for 24 hours Wash to be neutral and dry; then, place the above-mentioned dried licorice residue in a steam blaster, feed steam, stabilize the pressure for 2 minutes at a preset steam pressure of 2.0 MPa, and release the pressure instantly for explosion; finally, collect The blasted traditional Chinese medicine dregs were put into a constant temperature drying box, dried for 24 hours, and then pulverized. After pretreatment, the moisture content of the licorice dregs was 2.38%.

[0041] (2) Modified recycled polyeth...

Embodiment 2

[0052] A kind of Shichangpu medicinal dregs reinforced recycled polypropylene composite material is prepared according to the following steps:

[0053] (1) Pretreatment of Shichangpu medicine dregs

[0054] The medicinal dregs of Acorus calamus were pretreated by steam explosion method. Firstly, pick and remove impurities from Acorus shichangpu, put them into a crusher for crushing, and crush them into coarsely crushed Acorus shichangpu medicine residues; secondly, mix the above crushed shichangpu medicine residues with 1.0 mol / L sodium hydroxide aqueous solution After soaking for 24 hours, it was washed to be neutral and dried; then, the above-mentioned dried Acorus herb residues were placed in a steam blaster, and steam was introduced to stabilize the pressure for 4 minutes at the preset steam pressure of 1.0 MPa, and then the pressure was released and exploded instantly. ; Finally, collect the blasted traditional Chinese medicine dregs, put them into a constant temperature...

Embodiment 3

[0066] A kind of honeysuckle, sophora flavescens, licorice root, notoginseng mixed medicine dregs reinforced recycled polyethylene composite material, prepared according to the following steps:

[0067] (1) Pretreatment of mixed medicinal residues

[0068] The mixed medicinal residues were pretreated by steam explosion method. First, pick the mixed medicinal residues, remove impurities, put them into a crusher and crush them into coarse mixed medicinal residues; secondly, soak the above crushed mixed medicinal residues in 1.0mol / L sodium hydroxide aqueous solution for 24h Wash to be neutral and dry; then, put the above-mentioned dried mixed medicinal residues in a steam blaster, inject steam, and after stabilizing the pressure at the preset steam pressure of 4.0MPa for 10 minutes, release the pressure and explode instantly; finally, collect The blasted traditional Chinese medicine dregs were put into a constant temperature drying box, dried for 24 hours, and then pulverized. ...

Abstract

The invention relates to a Chinese medicine residue reinforced reprocessed plastic composite material, and a preparation method thereof, and belongs to the field of composite material. The Chinese medicine residue reinforced reprocessed plastic composite material comprises, by mass, 50 to 70% of Chinese medicine residue, 20 to 40% of modified reprocessed plastic, 2 to 10% of a mineral filling material, 2 to 5% of a compatilizer, 1 to 5% of a lubricant, 1 to 3% of a colouring agent, 1 to 3% of an anti-oxidant, and 1 to 3% of a light stabilizer. The preparation method comprises following steps: Chinese medicine residue pretreatment; reprocessed plastic modification; material mixing; pelletizing; extrusion moulding, and surface post-processing. The physical properties, mechanical properties, and weathering resistance of the Chinese medicine residue reinforced reprocessed plastic composite material are equal to or better than that disclosed in national standard GB / T 24508-2009 <wood-plastic flooring>; and the Chinese medicine residue reinforced reprocessed plastic composite material is capable of satisfying market requirements, and possesses insect expelling effect and mould resistance.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a traditional Chinese medicine dregs-reinforced recycled plastic composite material and a preparation method thereof. Background technique [0002] Wood-plastic composite materials are green and environmentally friendly composite materials formed by extrusion, injection, molding and other processes of plant fibers, plastics and additives. Wood powder, rice bran, straw and other plant fibers have been successfully used in wood-plastic composite materials. However, wood powder needs to consume a lot of wood, resulting in a shortage of wood resources; rice bran has a narrow source and is an important feed for livestock, and a large amount of rice bran will cause a shortage of food for livestock; although straw is an agricultural waste, it has seasonal harvesting problems. Cause storage difficulties, difficult to continue supply production. Therefore, the development ...
