Description
Technical field
The present invention relates to plastic products production technical field more particularly to a kind of high-intensity wood plastic pallets.
Background technique
With the development of the global economy with the raising of human living standard, the yield and dosage of plastic product also increasingly increasing
Long, however following " white pollution " causes serious pollution to the earth environment of human survival, when word is also resource
Serious waste.To " this kind of renewable resource of white pollution is recycled, and the way to turn waste into wealth meets the United Nations mankind
The requirement for the strategy of sustainable development that environmental organization proposes.
Agricultural crop straw accounts for 50% or so of crop biological yield, is renewable organic resource a kind of and its abundant, according to
The related seminar's investigation and analysis of zoning institute of the Chinese Academy of Agricultural Sciences, there are about 6.2 hundred million tons of stalks every year in China, these stalks are mostly by vain
Burn-up, so that vast resources wastes, Agro-ecology balance is destroyed, and pollutes environment.Therefore how rationally to utilize stalk and give up
The resources such as old plastics, are turned waste into wealth, and are just particularly important.
Summary of the invention
Based on background technique there are the problem of, the invention proposes a kind of high-intensity wood plastic pallets.The present invention is useless by agricultural
It abandons cotton stalk and wood plastics tray is made in polypropene recycled materials, there is excellent ecology and economic benefit, and the wood plastics tray prepared
Intensity is high.
The invention proposes a kind of high-intensity wood plastic pallets, are prepared by following raw material: modified cotton stalk powder 60-
80 parts, 50-70 parts of polypropene recycled materials, 1-5 parts of maleic anhydride inoculated polypropylene, 0.5-2 parts of phthalic acid, zinc stearate 1-
2 parts, 1-2 parts of polypropylene wax, 0.2-1 parts of diphenylamines, 0.2-1 parts of antioxidant 1010,0.5-1 parts of Azodicarbonamide, muscovite
3-7 parts, 1-10 parts of nanometer calcium carbonate, 2-8 parts of glass fibre, 2-8 parts of carbon fiber.
Preferably, the modified cotton stalk powder by the preparation method comprises the following steps: crushed after cotton stalk is dried, obtain cotton stalk powder, then
Complex enzyme formulation is uniformly sprayed on cotton stalk powder, temperature control enzymatic hydrolysis, drying obtains modified cotton stalk powder.
Preferably, the complex enzyme formulation is made of pectase and cellulase by weight 1:5-7.
Preferably, the dosage of complex enzyme formulation is the 0.8-1.7% of cotton stalk powder quality.
Preferably, the modified cotton stalk powder by the preparation method comprises the following steps: crushed after cotton stalk is dried, cross 20-200 mesh, obtain
To cotton stalk powder, then complex enzyme formulation is uniformly sprayed on cotton stalk powder, temperature is controlled at 45-55 DEG C, digests 35-45h, later
It is dried to moisture content under the conditions of temperature is 102-105 DEG C lower than 3%, obtains modified cotton stalk powder.
Preferably, the high-intensity wood plastic pallet is prepared as follows:
S1, will modified cotton stalk powder, polypropene recycled materials, maleic anhydride inoculated polypropylene, phthalic acid, zinc stearate,
Polypropylene wax, diphenylamines, antioxidant 1010, Azodicarbonamide, muscovite, nanometer calcium carbonate, glass fibre, carbon fiber are added
Into batch mixer, it is uniformly mixed, obtains mixture；
S2, it feeds the mixture into progress melt blending in extruder and is granulated, obtain pellet；
S3, pellet is injected into mold by plastic injection equipment, by mold and modular system, is extruded as pellet
Meet the high-intensity wood plastic pallet of design size requirement.
Preferably, in S1, batch mixer temperature is 90-100 DEG C, incorporation time 6-12min.
Preferably, in S2, extruder extrusion temperature is 168-175 DEG C.
The present invention is uniform by the complex enzyme formulation being made of pectase and cellulase later first by cotton stalk crushing at powder
It is sprayed on cotton stalk powder, digests, modified cotton stalk powder is obtained after drying.Cotton stalk powder degree of polymerization of its cellulose after enzymatic hydrolysis subtracts
Small, the molecular weight of cotton stalk powder reduces, and improves the temperature flowing of cotton stalk powder, to improve point of the cotton stalk powder in polypropylene
Dissipate property.Interlock the system combined in addition, the aggregation of cotton stalk fiber element macromolecular forms crystal region and amorphous region, in crystal region
Fiber molecule chain orientation is good, and inter-molecular binding force is most strong, and fibre strength intensity is high, and high microsteping intensity directly promotes the strong of pallet
Degree；And amorphous region molecules align is unordered, intermolecular distance is larger, makes cellulose by the mating reaction of pectase and cellulase
Amorphous region hydrolysis occurs and to crystal region internal penetration, so that crystal region surface is generated the soluble micro-crystallization in part, fiber table
Face becomes coarse, so that fiber and polypropylene molecule contact surface increase, improves the interface wellability of two-phase, forms interface
Deeper interface diffusion layer and stronger mechanical anchor cooperation are used, and the enhancing of both fiber and polypropylene binding force can when by external force
Effectively to transmit and bear load, has the function that increase wood plastic composite intensity, be embodied in the mechanical property of pallet
It improves.Later, the present invention will be modified cotton stalk powder, polypropene recycled materials, maleic anhydride inoculated polypropylene, phthalic acid, tristearin
Sour zinc, polypropylene wax, diphenylamines, antioxidant 1010, Azodicarbonamide, muscovite, nanometer calcium carbonate, glass fibre, carbon fiber
Dimension is uniformly mixed, extrusion granulation, reinjects in mold and high-intensitive wood plastics tray has been made.Wherein, maleic anhydride grafting poly- third
The addition of alkene can increase substantially polypropylene and nanometer calcium carbonate, glass fibre, carbon fiber, muscovite and modified cotton stalk powder etc.
Bonding force, to significantly improve the comprehensive mechanical property such as the tensile strength of pallet, bending strength, impact strength, heat distortion temperature
Energy；The addition of zinc stearate, polypropylene wax can reduce the frictional resistance between raw material and between raw material and processing equipment, change
Kind mobility, promotes machine-shaping, and improve the surface quality of product；Diphenylamines is added, antioxidant 1010 can prevent product
Aging prolong its service life；Muscovite belongs to inorganic rigid particle, and the rigidity that can improve pallet significantly is added, and
Muscovite has unique two-dimensional sheet structure, is dispersed in polypropylene matrix, and white clouds coatingparticles can be used as stress concentrate,
Play the role of enhancing pallet toughness；The intensity and toughness of pallet can be improved in nanometer calcium carbonate, and it is anti-also to can be used as physical protection agent
Only high-temperature thermal oxidation occurs for plant fiber；Glass fibre and carbon fiber are reinforcing fiber, and high intensity can guarantee raw material tool
On the basis of having excellent machinability, pallet physical and mechanical property is improved, the dimensional stability of wood plastic composite can be also improved
And heat resistance.In short, wood plastics tray is made in agriculture waste cotton stalk and polypropene recycled materials by the present invention, with excellent ecology and
Economic benefit, and the wood plastics tray intensity prepared is high.
