Embodiment 1

[0027] A preparation method of degradable plant fiber environmental protection composite material that can be processed by thermoforming such as extrusion or blister, is characterized in that it includes the following steps:

[0028] (1) After the chaff is pulverized by a mill, it is vibrated and screened to get a fiber powder with a particle size of 200 meshes, and the cellulose powder is stirred and incubated in acetic anhydride for 2 hours at 120 ° C under an atmospheric pressure of 4 kg. , cooled and filtered, directly dried without washing.

[0029] (2) Then in parts by mass, 40 parts of modified plant fiber powder, 60 parts of thermoplastic resin, 1.5 parts of compatibilizer, 0.9 part of coupling agent, 0.5 part of lubricant, 1 part of heat stabilizer, 2 parts of filler, pigment 2 parts, 1 part of other additives, mixed with a vertical mixer, initially stirred at a high speed of 25rpm / min for 7.5min, and then stirred at a low speed of 7.5rpm / min for 3-5min; the thermopla...

Embodiment 2

[0032] Same as Example 1, except by mass, 50 parts of modified plant fiber powder, 50 parts of thermoplastic resin, 1.5 parts of compatibilizer, 0.9 part of coupling agent, 0.5 part of lubricant, 1 part of thermal stabilizer, 2 parts of filler 1 part, 2 parts of pigment, 1 part of other additives. The other additives are metal stearic acid, ethylene-ketone-containing monomer copolymer (1:1) mixture.

Embodiment 3

[0034] Same as Example 1, except by mass, 60 parts of modified plant fiber powder, 40 parts of thermoplastic resin, 1.5 parts of compatibilizer, 0.9 part of coupling agent, 0.5 part of lubricant, 1 part of thermal stabilizer, 2 parts of filler 1 part, 2 parts of pigment, 1 part of other additives. The other additives are metal stearic acid, ethylene carbon monoxide copolymer (1:1) mixture.

Abstract

The invention provides a degradable vegetable fiber environmental-protection composite material capable of being subjected to extrusion or plastic suction thermal molding, wherein the material comprises, by mass, 5-85 parts of modified plant fiber powder, 5-85 parts of a thermoplastic resin, 0.1-1 part of a lubricant, 0.1-4 parts of a pigment, and 0.2-1 part of other auxiliary agents. According tothe present invention, the environmental-protection composite material is easy to degrade, and is formed by compounding plant fibers and a thermoplastic resin, such that the materials are convenientto take.

Description

technical field [0001] The invention relates to a degradable plant fiber environment-friendly composite material that can be extruded or thermoformed. Background technique [0002] In the prior art, the main materials of products such as sheets, plates, profiles, films, and load-bearing pallets are made of pure plastic or wooden materials. The use of pure plastics causes great environmental pollution, while the use of wood causes serious damage to the natural environment due to a large amount of felling, causing serious soil erosion, and with the improvement of people's living standards, the demand for natural resources is increasing, which intensifies various Due to the shortage of resources, the cost is also rising continuously. And my country is a big agricultural country, produces a large amount of stalk wastes every year, as rice stalk, wheat stalk, corn stalk, chaff etc., if can effectively utilize fully, will play very good protective effect to ecological environment...
