Abstract
The present invention provides a preparation process of wood-plastic composite material, and features that polyolefin and wood powder as main material and ionic polymer as compatilizer accounting for 5-10 wt% of the mixed material are mixed in a high speed mixer for 20-40 min at the temperature lower than 100 deg.c, and the mixture is then formed through extrusion or mold injection. Compared with available technology, the product has the advantages of high hardness, high strength, smooth surface, etc. and may be used widely in door and window, floor, wall, etc.
Description
Affiliated technical field:
(PE PP)/oak powder/prepare the preparation method of wood plastic composite from aggressiveness, is that a kind of polyolefine and oak powder of adopting is the method that major ingredient prepares wood plastic composite specifically to the present invention relates to a kind of polyolefine.
Background technology:
The wood plastic composite that xylon, wood powder and thermoplastic polymer form is a kind of emerging advanced composite material that broad development and application prospect are arranged in the world today.Because it combines the advantage of plastics and timber, have long service life, attractive in appearance, renewable, cost is low, insect protected, anticorrosion, antiskid, can spray, than the hardness height of pure plastic prod, can equally with timber process, advantage such as bonding and fixing, so wood plastic composite is widely used in material of construction, marine material, fence material, furniture material, automotive material of door and window, floor, wall etc.Wood plastic composite is a kind of very effective means for solution forest reserves scarcity, petroleum resources worsening shortages.
Because wood powder and polyolefins plastics polarity differ bigger, cause the two consistency bad, and wood powder and the compound composite materials property that obtains of polyolefin resin is not ideal enough.Domestic and international research work at present all is to handle wood powder or directly add polyolefinic maleic anhydride grafts by coupling agent (silicane, titanate ester) to improve the interface compatibility of the two, has all played certain effect.But in the wood plastic composite actual production process, also to solve the problem such as slickness, processing fluidity, raising rate of extrusion of product surface, compatilizer or coupling agent general aspect addressing these problems can not obtain satisfied effect, and add the performance that other processing aid can influence the finished product.Therefore seek a kind of mechanical property that can either improve wood powder and polyolefinic interface compatibility, improve product, the auxiliary agent that can solve the various processing problems in the actual production simultaneously again is most important.
Summary of the invention:
Technical problem to be solved by this invention is: wood powder and polyolefins polarity differ bigger, and consistency is bad, and common wood-plastic composite goods bounding force is little, and surface flatness is relatively poor, and mobile bad.The present invention provides a kind of preparation method of novel wood-plastic matrix material for solving the problems referred to above in the prior art, and described preparation method is as follows:
With polyolefine and oak powder as major ingredient, with ionic polymer (for example ethylene-methacrylic acid copolymer) as compatilizer, the compatilizer consumption is 5～10% of a mixture quality, in homogenizer, mixed 20～40 minutes, temperature is controlled in 100 ℃, adopts extrusion moulding or injection moulding.
Further, polyolefine selects melt flow rate (MFR) at 0.5～7.0g/10min
Further, described polyolefine is a high density polyethylene(HDPE), new LDPE (film grade), linear low density of polyethylene, medium-density polyethylene, the reworked material of polypropylene and said polyolefins thereof.
Further, described forming technique is twin screw extruder extrusion moulding or injection moulding in injection moulding machine, or adopts existing plastics forming technique such as pressure forming.
The present invention and prior art contrast, and have the following advantages:
1. the required oak powder of this matrix material is the offal in the Oak Tree wood working, and used plastics promptly can be polyolefin resin finished product, the also reworked material of available waste polyolefine plastics.Be very significant to solving the wasting of resources and environmental problem undoubtedly.
2. because wood powder and polyolefine (polyethylene, polypropylene) polarity differs bigger, consistency is bad, the present invention adopts the compatilizer of high molecular polymer (ethylene-methacrylic acid copolymer) as both, improved processing fluidity greatly, improve the slickness of product surface, and helped the raising of extruded velocity, more helped the bonding of with other material compound or technologies such as coextrusion and compound pad pasting.
