Description
Technical field
The present invention relates to a kind of Wood plastic composite and preparation method thereof, a kind of specifically continuous fiber strengthens polyolefine Wood plastic composite and preparation method thereof.
Background technology
Wood plastic composite is a kind of emerging environmental protection, the matrix material of low-carbon (LC).Main recovery plastics and the agriculture and forestry organic waste material of adopting is processed into bed board, guardrail fence or indoor and outdoor and decorates as raw material.But, can't be widely used in building field, particularly stressed member or structural part because the mechanical property of Wood plastic composite is lower.
For fibre reinforced plastics a lot of reports and related patent U.S. Patent No. have been arranged both at home and abroad, but the distribution of glass in product is discontinuous phase, remains local pressure when product is stressed.Like long glass fiber reinforced polypropylene material and preparation method thereof (application number: 200810020936.5); Be long glass fibres to be immersed in the Vestolen PP 7052 use after the pelletizing; Its shortcoming is that spun glass remains discontinuous state; Reinforced effects for product is relatively poor with respect to the continuous fibre enhancing, and spun glass can be continued to cut off in product following process process, simultaneously there are wearing and tearing in processing units.In addition, common glass fibre reinforcement difficulty when reclaiming is bigger, and spun glass is difficult to from material, separate.
Summary of the invention
Technical problem to be solved by this invention is: to the shortcoming of above prior art existence; Propose a kind of continuous fiber and strengthen polyolefine Wood plastic composite and preparation method thereof; Can significantly strengthen the mechanical property of Wood plastic composite, expand the Application Areas of Wood plastic composite.
The technical scheme that the present invention solves above technical problem is:
A kind of continuous fiber strengthens the polyolefine Wood plastic composite, and is composed of the following components by weight percentage: polyolefin plastics 20-80%, xylon 0-80%; Mineral-filled thing 0-80%, lubricant 0-10%, inhibitor 0-5%; UV light absorber 0-5%; Coupling agent 0-10%, pigment 0-10%
Fortifying fibre 0-30%; Fortifying fibre is surface-treated or unmodified spun glass, flaxen fiber or monkey grass; Fortifying fibre extends along polyolefine Wood plastic composite length direction continuously, and quantity is at least a branch of.
The present invention makes fortifying fibre being distributed in the polyolefine plastic-wood section of extension continuously; When plastic-wood section is in use stressed; The fiber that extends continuously can be passed to section bar integral body rapidly with local pressure, thereby significantly improves the intensity and the shock resistance of plastic-wood section.In addition, fortifying fibre uses flaxen fiber or monkey grass, and the feature of environmental protection is stronger; Monkey grass particularly can guarantee the intensity of fiber can guarantee the feature of environmental protection again.
Continuous fiber of the present invention strengthens the preparation method of polyolefine Wood plastic composite, carries out according to the following steps:
(1) batch mixing: with polyolefin plastics particle, xylon, mineral-filled, lubricant, inhibitor, UV light absorber, coupling agent and pigment were poured the mixer mixing into 3-5 minute in proportion;
(2) granulation: the raw material after will mixing adds parallel double-screw extruder and carries out the compounding granulation, obtains moulding wood aggregate;
(3) extrude: will mould wood aggregate and add forcing machine, fusion after mould extrude; In the step (3), mould the wood aggregate fusion after mould when extruding in die side to adding continuous fortifying fibre, control forcing machine body temperature, die temperature and extruded velocity make plastic-wood material in moulding, coat glass and extrude together; Body temperature is 100-200 ℃, and die temperature is 100-200 ℃, and extruded velocity is 100-1000mm/min.
This bright science with fortifying fibre in die side to adding simultaneously; It is extruded with moulding wood aggregate; Form " co-extrusion ", can guarantee that fortifying fibre extends continuously and do not cut off in plastic-wood material, reach the intensity that improves plastic-wood section and the purpose of shock resistance.In addition, body temperature is controlled at 100-200 ℃, and die temperature is controlled at 100-200 ℃; Extruded velocity is controlled at 100-1000mm/min, and the setting of body temperature mainly is based on the fusing point of Wood plastic composite, makes the abundant fusion of Wood plastic composite; Promote the dispersion of xylon in plastics, the control through die temperature makes Wood plastic composite when mould is extruded, and has good structure hold facility on the one hand; Can coat continuous fiber again on the other hand; Macrofiber is dispersed in the plastic-wood section uniformly, improves reinforced effects, guarantee the continuity that product is extruded.Extruded velocity is slow excessively, and production efficiency is low, extruded velocity is too fast then cause continuous fiber and plastic-wood material combine not closely, be easy in use occur the running phenomenon.
