Description

A kind of production technology of high-intensity wood plastic composite
Technical field
The present invention relates to field of compound material, be specifically related to the production technology of a kind of high-intensity wood plastic composite.
Background technology
Wood plastic composite is the class advanced composite material (ACM) in recent years risen both at home and abroad, refer to utilize the thermoplastics such as polyethylene, polypropylene and polrvinyl chloride, replace resin adhesive, the novel wooden material mixed with useless Plant fiber such as a number of wood powder, rice husk, straws, then through plastic processings such as extruding, mold pressing, injection mouldings, the sheet material produced or section bar, be the excellent succedaneum of natural timber. Wood plastic composite has the double grading of timber and plastics, good stability of the dimension, can make full use of again discarded Plant fiber and waste or used plastics, reduces environmental pollution, so being widely used in interior decoration and outdoor use.
Plant fiber is polar substances, and great amount of hydroxy group is contained on surface, and plastics (such as PE, PP) are apolar substances, very poor with the interface compatibility of Plant fiber, generally adds compatilizer (such as maleic anhydride graft PE) and improves interface compatibility. Compatilizer typically contains the macromolecule polyalcohol of polar group (such as anhydride group, carboxyl), its polar group can with the hydroxyl generation esterification of plant fibre surface, the macromolecular chain of compatilizer and thermoplastic have the goodish compatibility, thus improving the interface compatibility of Plant fiber and plastics.
At present, the production technology of wood plastic composite is all be simultaneously introduced in high-speed mixer after mix homogeneously by nearly all raw materials such as compatilizer, lubricant, pigment direct parallel double-screw extruder to plastify pelletize, conical double screw extruder extrusion molding. Wood plastic composite has certain water absorption rate, and after water suction, the mechanical strength of wood plastic composite sharply declines, and freezing and thawing performance is deteriorated, antimildew and antibacterial penalty, and water suction warpage, problems of crack even occur.
Summary of the invention
The present invention provides a kind of water absorption rate reducing wood plastic composite, improves the production technology of the high-intensity wood plastic composite of the intensity of wood plastic composite.
In order to achieve the above object, the present invention adopts following technical proposals:
A kind of production technology of high-intensity wood plastic composite, it is characterised in that: comprise the following steps:
(1) Plant fiber is dried so that the moisture content of Plant fiber is 0.3%-0.5%;
(2) being placed in mixer cold mixed 8-10min by dried 20-80 weight portion Plant fiber, 10-30 parts by weight of thermoplastic and 3-10 parts by weight of compatible agent by proportioning, speed of agitator controls at 200-350rpm, and temperature controls at 80-90 DEG C;
(3) mixed material is transported in parallel double extruser to carry out first time pelletize, is 160-190 DEG C at prilling temperature, when engine speed is 300-400rpm, obtains wood plastic particles;
(4) being placed in mixer by gained wood plastic particles and 1-5 weight portion lubricant, 1-10 weight portion pigment cold mixed 10-15min, speed of agitator controls at 200-350rpm, and temperature controls at 80-90 DEG C, mix homogeneously;
(5) by the mixture in step (4), being transported to parallel double extruser and carry out pelletize again, prilling temperature is 160-190 DEG C, and engine speed is 300-400rpm, obtains just material;
(6) gained just material is transported to conical double ribbon screw extruder, temperature be 140-180 DEG C, screw speed be 30��70rpm, charger rotating speed is extrusion molding under 20��60rpm.

This is likely due to prior art and all raw materials and additive is all simultaneously introduced pelletize, lubricant and pigment is made to destroy the esterification of Plant fiber and compatilizer, thus the interface compatibility destroyed between Plant fiber, compatilizer, plastics three, the intensity making wood plastic composite is difficult to increase substantially, water absorption rate is difficult to further reduction, or even cause a series of contingency question, as easily mouldy, water suction warpage, cracking etc. Such as conventional lubricant stearic acid zinc, calcium stearate etc. can interact with anhydride group, carboxyl, moisture etc., chemical reaction, generation stearic acid occurring, thus destroying esterification, reducing interface compatibility.
As preferably, described Plant fiber is one or more in wood powder, bamboo powder, powder of straw, corn stalk powder, bran powder.
As preferably, described thermoplastic is one or more in PP, PE, ABS, PVC, PS, EPDM.
As preferably, described compatilizer is one or more in maleic anhydride graft PP, maleic anhydride graft PE, maleic anhydride grafted ABS, maleic anhydride graft PVC, maleic anhydride graft PS, maleic anhydride graft EPDM, acrylic acid-grafted PP, acrylic acid-grafted PE, acrylic acid-grafted ABS, acrylic acid-grafted PVC, acrylic acid-grafted PS, acrylic acid-grafted EPDM.
As preferably, described lubricant is one or more in oleamide, zinc stearate, calcium stearate, stearic acid, polyol ester.
As preferably, described pigment is one or more of iron oxide red, iron oxide yellow, oxide tillandsia, iron oxide purple, iron oxide brown and iron oxide black.
As preferably, described thermoplastic is one or both in PP, PE;Described compatilizer is one or both in maleic anhydride graft PP, maleic anhydride graft PE; Described lubricant is one or more in oleamide, zinc stearate, calcium stearate.
As preferably, the 70%-80% that electric current is main frame rated current that described step (3) granulation process uses; The 50%-60% that electric current is main frame rated current that step (5) granulation process uses.
The present invention adopts technique scheme, compared with prior art, has following remarkable advantage:
By twice pelletize, lubricant is added after first time pelletize, overcoming lubricant and destroy the deficiency of the interface compatibility between Plant fiber, compatilizer, plastics three, thus effectively reducing the water absorption rate of wood plastic composite, improving the intensity of wood plastic composite.
