Embodiment 1

[0030] Add 20 parts by mass of whole biomass polyethylene, 60 parts by mass of starch, 5 parts by mass of glycerol, and 15 parts by mass of calcium carbonate into a high-speed mixer, stir at 120°C for 20 minutes, and mix well; then the mixture is extruded in a twin-screw Mixing and granulation at 180°C in the exiting machine can obtain the all-biomass composite injection molding material; after secondary processing on the injection molding equipment, the all-biomass composite injection molding product can be obtained.

[0031] The properties of all biomass composite injection molding materials are as follows:

[0032]

Embodiment 2

[0034] Add 45 parts by mass of whole biomass polyethylene, 40 parts by mass of starch, 10 parts by mass of ethylene glycol, and 15 parts by mass of talcum powder into a high-speed mixer, stir at 150°C for 30 minutes, and mix well; then the mixture is extruded in a twin-screw Mixing and granulation at 220°C in the exit machine can obtain the whole biomass composite plastic; after secondary processing on the blow molding equipment, the whole biomass composite plastic film bag can be obtained.

[0035] The properties of all biomass composite plastics are as follows:

[0036]

Embodiment 3

[0038] Add 50 parts by mass of whole biomass polyethylene, 30 parts by mass of cellulose (straw powder), 5 parts by mass of propylene glycol, and 15 parts by mass of calcium carbonate into a high-speed mixer, stir at 100°C for 20min, and mix well; then put the mixture in Mixing and pelletizing at 180°C in a twin-screw extruder to obtain a full-biomass composite plastic; after secondary processing on a blow molding device, a full-biomass composite plastic film bag is obtained.

[0039] The properties of all biomass composite plastics are as follows:

Abstract

The invention discloses a total biomass composite injection moulding material and a preparation method thereof. The raw materials of the total biomass composite injection moulding material contain the following components in part by weight: 20-50 parts of total biomass polyethylene; 30-60 parts of a biomass material; 5-20 parts of a plasticizer; 15-30 parts of a filling material. The preparation method comprises the following steps: raw materials are uniformly mixed and added into a double screw extruder, a mixing is carried out at 150-220 DEG C, a granulation is carried out, and the product is obtained. Raw materials of the products are totally selected from natural renewable substances, thermoplastic renewable substances are blended with the total biomass polyethylene for granulation, along with biodegradation of renewable substances, the whole material is disintegrated into fragments, so that the material has a certain degradation performance.

Description

technical field [0001] The invention relates to an all-biomass composite injection molding material and a preparation method thereof, belonging to the field of polymer materials. Background technique [0002] The raw material of plastic preparation process comes from petroleum. However, with the rapid development of social economy and the shortage of petroleum resources, the impact of greenhouse gas emissions on the global climate has increasingly become the focus of attention all over the world. Reducing the use of petroleum resources and reducing carbon emissions has become the goal of everyone's joint efforts. [0003] The main raw material of biomass materials is from renewable agricultural resources, which can be used in the preparation process of plastics as a supplementary substitute for limited, decreasing and depleting non-renewable petroleum resources. The current biomass materials generally have the problem of low strength. Contents of the invention [0004] T...
