Abstract

The invention relates to the composite material field, and concretely relates to a production technology of a high-strength wood plastic composite material. The technology comprises the following steps: 1, uniformly mixing 20-80 parts by weight of a dried vegetable fiber, 10-30 parts by weight of a thermoplastic plastic and 3-10 parts by weight of a compatilizer in a mixer; 2, transporting a mixture obtained in step 1 to a parallel double screw extruder, and carrying out primary granulation to obtain wood plastic particles; 3, uniformly mixing the wood plastic particles, 1-5 parts by weight of a lubricant and 1-10 parts by weight of a pigment in the mixer; 4, transporting a mixture obtained in step 3 to the parallel double screw extruder, and carrying out secondary granulation to obtain a primary material; and 5, transporting the obtained primary material to a conical double screw extruder, and carrying out extrusion molding. The influences of the lubricant to the interface compatibility among the vegetable fiber, the compatilizer and the plastic are avoided through the separate addition of the lubricant and the above two-time plasticizing granulation, so the water absorption rate of the wood plastic composite material is effectively reduced, and the strength of the wood plastic composite material is increased.

Description

A kind of production technique of high-intensity wood plastic composite
Technical field
The present invention relates to field of compound material, be specifically related to a kind of production technique of high-intensity wood plastic composite.
Background technology
Wood plastic composite is a class advanced composite material that in recent years rises both at home and abroad, refer to utilize the thermoplasticss such as polyethylene, polypropylene and polyvinyl chloride, replace resin adhesive, the novel wooden material that mixes with useless vegetable fibres such as the wood powder of some amount, rice husk, stalks, again through plastic processings such as extruding, mold pressing, injection moldings, the sheet material of producing or section bar are the good substitutes of natural timber.Wood plastic composite has the dual nature of timber and plastics, and good stability of the dimension can take full advantage of discarded vegetable fibre and waste or used plastics again, and environmental contamination reduction is so be widely used in interior decoration and outdoor use.
Vegetable fibre is polar material, and great amount of hydroxy group is contained on the surface, and plastics (such as PE, PP) are apolar substances, and is very poor with the interface compatibility of vegetable fibre, generally adds compatilizer (such as maleic anhydride graft PE) and improves interface compatibility.Compatilizer generally contains the high polymer of polar group (such as anhydride group, carboxyl), its polar group can with the hydroxyl generation esterification on vegetable fibre surface, the macromolecular chain of compatilizer and thermoplastics have goodish consistency, thereby improve the interface compatibility of vegetable fibre and plastics.
At present, the production technique of wood plastic composite all is nearly all raw materials such as compatilizer, lubricant, pigment to be added to mix in the high-speed mixer simultaneously directly plastify granulation with parallel double-screw extruder, the conical double screw extruder extrusion moulding afterwards.Wood plastic composite has certain water-intake rate, and after the suction, the mechanical strength of wood plastic composite sharply descends, freezing and thawing performance variation, antimildew and antibacterial mis-behave, even suction warpage, problems of crack occur.

As preferably, described lubricant is one or more in amine hydroxybenzene, Zinic stearas, calcium stearate, stearic acid, the polyol ester.
As preferably, described pigment is one or more of red iron oxide, iron oxide yellow, oxide tillandsia, iron oxide purple, iron oxide brown and iron oxide black.
As preferably, described thermoplastics is one or both among PP, the PE; Described compatilizer is one or both among maleic anhydride graft PP, the maleic anhydride graft PE; Described lubricant is one or more in amine hydroxybenzene, Zinic stearas, the calcium stearate.
As preferably, the electric current that described step (3) granulation process uses is the 70%-80% of main frame rated current; The electric current that step (5) granulation process uses is the 50%-60% of main frame rated current.
The present invention adopts technique scheme, compared with prior art, has following remarkable advantage:
By twice granulation, lubricant is added after the granulation first time, overcome lubricant and destroyed the deficiency of the interface compatibility between vegetable fibre, compatilizer, the plastics three, thereby effectively reduced the water-intake rate of wood plastic composite, improved the intensity of wood plastic composite.
