Description
Technical field
The present invention relates to field of compound material, be specifically related to a kind of ecological matrix material and preparation method thereof.
Background technology
Along with the development that the reinforcement and the renewable resources of people's environmental protection consciousness utilizes technology, powerful in the global evolution impetus with the ecological matrix material that discarded synthesized polymer material that reclaims and natural macromolecular material are feedstock production.At present, employed synthesized polymer material comprises thermoplasticss such as polyethylene, polyvinyl chloride, polystyrene in the ecological matrix material of this class (as section bar); And natural macromolecular material mainly is some depleted vegetable fibres, comprises wood powder, bamboo powder, stalk, rice husk, Pericarppium arachidis hypogaeae etc.Both according to a certain percentage and add some processing aids, coupling agent etc. prepare corresponding section bar and goods through the melt blending molding device.The bending strength of this class composite material, hardness, wear resistance, water tolerance and anti-damaging by worms property etc. have all surpassed solid wood or solid wood matrix material, and apparent color and luster approaches solid wood material substantially, product can be sawed, digs, follow closely simultaneously, use maintenance easy, be widely used in outdoor building material (as floor, bed board, fence, guardrail), communications and transportation fields such as (as automotive trim, seat backup plates).Yet this class material also exists following common problem: creep-resistant property is poor, and dimensional stability is not good enough, and MOR is general, and especially toughness is far away from the excellence of timber performance.Therefore, be necessary further to research and develop this new green environment protection material, improve the quality of this series products, widen its Application Areas.
Because polarity and consequent intermolecular hydrogen bonding that the vegetable fibre surface is had, dispersiveness and surface adhesion between hydrophilic filler and the resin have been hindered, thereby influenced the composite effect of the ecological composite material of this class, after the vegetable fibre loading level arrived certain value, the MOR of material, creep-resistant property and toughness reduced obviously.Therefore must carry out modification to vegetable fibre, eliminate or reduce its surface polarity degree, improve the interface performance and the composite effect of composite material.
At present, the method that vegetable fibre is carried out modification has physics and chemical modification method.
Physical method mainly contains: 1) stretching, calendering, thermal treatment, blending etc., in order to change the structure and the surface properties of fiber, be convenient to the mechanical snap of fiber and matrix resin in the recombination process; 2) discharge technology comprises methods such as corona, low-temperature plasma, radiation.Corona treatment techniques is the functional group on activation fiber surface in a large number, changes the surface energy of fiber; The gas with various that the Low Temperature Plasma Treating technical basis is loaded with carries out the seriation surface treatment to xylon, makes fiber surface produce free radical and functional group; Discharge means is the method for inertial base resin such as polystyrene (PS), polyethylene (PE), polypropylene (PP) etc. being carried out modification; 3) gas explosion method: the method for gas instantaneous explosion causes that the form of vegetable fibre and structure change, thereby the intensity of vegetable fibre and specific surface area are increased.
Chemical modification is handled the quantity that vegetable fibre is intended to reduce the fiber surface hydroxy functional group, or introduces laterally crosslinked and compatible between vegetable fibre and resin matrix by the mode of physics or chemical bonding.Therefore the chemical modification processing is the method that fundamentally solves the two-phase material compatibility, also is a focus of studying at present both at home and abroad.Chemical modification method mainly contains:
1) compatilizer method, as making compatilizer with grafting vegetable fibres such as maleic anhydride or maleic anhydride modified polyolefin resin, also can adopt with blend two-phase or multiphase can both be well compatible general character compatilizer etc.; Especially the modified by maleic acid anhydride graft polymkeric substance is the comparatively successful a kind of compatilizer of commercial applications, just begin widespread use in ecological composite material as far back as the beginning of the nineties in last century, it is still all having remarkable advantages aspect the complete processing optimizing no matter aspect interface binding power that improves vegetable fibre and interlaminar resin and consistency.
2) coupling agent method as adopting coupling agent treatment fibers such as silane, isocyanic ester, titanic acid ester, aluminic acid ester, is improved the consistency of vegetable fibre and resin.Coupling agent is through hydrolysis, condensation and vegetable fibre, resin matrix generation chemical bonding or free radical reaction, make the interface binding power between modified plant fibers and the resin strengthen, help the homodisperse of vegetable fibre in resin matrix, but certain fineness must be pulverized, be ground to form to preprocessing plant fibre earlier, adds to carry out physical mixed behind the corresponding coupling agent and stir again.
3) alkali metal soln facture, the intensity and the specific surface area of increase wood powder fiber.The vegetable fibre cheap for some, that the xylogen equal size is more need carry out alkali lye earlier and remove, and this technology can increase production cost and need carry out the efforts at environmental protection of liquid waste disposal.
