High agricultural product (187,000,000,000 U.S. dollar of global economic impact in 2011).For a long time, agricultural crop straw is mainly used as fertilizer, combustion
Material, feed and paper making raw material, utilization rate is less than 50%.Remaining major part stalk all does burning disposal, results in serious haze
And other air pollutions.
Full biomass polyethylene be as wood-based composites (using biomass as raw material by fermentation made from ethyl alcohol, biomass
Raw material includes the crops containing carbohydrate and starch such as corn, sorghum, wheat, barley, sugarcane, beet and potato) catalytic dehydration system
The ethylene obtained, then the polyethylene polymerizeing.The full biomass polyethylene and the polyethylene physical chemistry made of fossil resources
Performance is similar, while also has the environment-friendly advantages such as low-carbon, renewable.
Applicant has studied the technology that plastics are prepared using full biomass polyethylene before, referring to publication number
The Chinese patent literature of CN105585759A uses full biomass polyethylene, natural high molecular substance, additive and filler.It should
Though biomass combined plastics have some superiority compared to the plastics based on other biological matter, still need in mechanical property
It further improves.
Invention content
Stalk full biomass plastics of the prior art, since the modified effect to stalk is limited, produce in preparation process
There is larger gap with conventional plastic in the full biomass plastics mechanical property gone out, requirement used in everyday can not be met.In order to
Solve the problems, such as these, the present invention provides a kind of full biomass cellulose composite plastics.

It is found through overtesting, the full biomass cellulose composite plastic that each ingredient of above-mentioned amount ranges is selected to prepare,
Mechanical property such as tensile strength, elongation at break, elasticity modulus and impact strength is more excellent.
The present invention also provides the preparation methods of the full biomass cellulose composite plastic of any description above, and being will be compatible
Agent is made into ethanol solution, is uniformly sprayed in the mixture of straw powder and nano redigity organic material, is dried after being placed at room temperature for, then
It is uniform to add in surplus stock stirring and mixing at 60~150 DEG C, adds in double screw extruder, in 130~220 DEG C of mixings, makes
Grain.
Preferably, it is 6 hours to be placed at room temperature for the time, and drying condition is 105 DEG C of dry 2h.
The invention has the advantages that：
1st, nano redigity organic material used in the present invention can significantly increase the mechanical property of composite material, and add
Dosage is small, easy to process.
2nd, the present invention is used compatilizer wiring solution-forming, is uniformly sprayed to CNCs/ straw powders or CNFs/ straw powder mixing materials
On material, it ensure that CNCs or CNFs do not reunite, can uniformly disperse open, play the role of effectively promoting system mechanical property.
3rd, full biomass polyethylene is blended using straw powder in the present invention, and straw powder is made to be dispersed in full biomass polyethylene
In matrix, with the biodegradation of straw powder, the disintegration of full biomass material fragmentates, and has material a degree of degradable
