Composite material, and preparation method is further disclosed.
Background technique
Wood plastic composite is using thermoplastic, including polyethylene, polypropylene, polystyrene and their copolymerization
Object etc. is used as basis material, makees reinforced phase with the discarded natural fiber such as wood powder, rice husk, wheat straw, cornstalk, peanut shell, adds
A small amount of chemical addition agent and filler, a kind of composite material made by certain processing technology.Wood plastic composite is simultaneously
Has the advantages of plant fiber and plastics, with anti-corrosion, moisture-proof, Anti-moth-eating, dimensional stability is high, do not crack, warpage etc. is not excellent
Point, and have the characteristics that raw material resources, product plasticization, using environmental protection, cost economization, reclaiming.Modeling wood is multiple
The scope of application of condensation material is very extensive, can almost cover all logs, plastics, plastic-steel, aluminium alloy and other similar composite woods
Material uses field, is widely used as outdoor flooring, swimming pool bound edge, flower case, Shu Chi, hedge, dustbin, sunshading board, stool, chair
Item, by back bar, leisure tabletop, direction board, propaganda board, crossbeam, harbour bed board, channel waterborne, handrail, guardrail, fence, partition,
Flower stand corridor, outdoor wayside pavilion, sun deck, bathroom plate, sash set, abatvoix, top plate etc., while also solving plastics, wood
The regeneration problem of material industry waste resource.
With the raising of Wood plastic composite production technology, the expansion of industry size and its own environmental protection characteristic outstanding and
Unique decorative effect, the application of field (such as door and window, floor, furniture) is gradually expanded indoors.However, since modeling wood is multiple
The thermoplastic of one of the primary raw material of condensation material be good electrical insulator, with lignocellulosic material it is compound after still fall within electricity
Non-conductor, be easy a large amount of electrostatic charge of accumulation in use, cause the danger such as dust suction, electric discharge, breakdown, or even cause
Burning or explosion, there are huge security risks, and then limit the application field of Wood plastic composite.
The flame-retardant and anti-static wood plastic composite as disclosed in Chinese patent CN104327530A passes through addition such as powdery
Metal powder or the modes of the antistatic agents such as sheet, the graphite substance of powdery improve the antistatic property of plastic-wood material.This
The metal powder of powderies, graphite-like conductive materials are poor with the compatibility of plastics and wood powder in mixed process a bit, so that these objects
Matter can be enriched in the surface of modeling plank after shaping, the continuous conduction film of layer be formed, so that resisting for optic panel is quiet
Electric effect is preferable, and surface resistivity generally can achieve 107-109Ω, but accordingly also cause the antiskid performance of optic panel compared with
Difference, the article being placed on when as loading plate easily slide, and slip as floor Shi Renyi, safety is lower；Moreover, smooth surface
Plate is after wire brush carries out brushing processing, the relative coarseness that surface can become, although skid resistance improves, surface at this time
The conductive film being formed by graphite can become discontinuous, and antistatic property is poor, and surface resistivity basically reaches 1012Ω or more, can not
It is used applied to the field for having higher anti-skidding, antistatic requirement to surface.Moreover, with such such as metal powder, graphite powder power
The increase for learning the antistatic substance dosage of performance difference, also results in the mechanics such as entire Wood plastic composite bending resistance
Performance is substantially reduced, therefore, as the antistatic plastic-wood material of Chinese patent CN104327530A etc can not be applied to bending resistance
The more demanding field for example inflammable and explosive cargo pallet class loading plate of song, Surface Anti-slide, floor etc..

Product.
Comparative example 9
Wood plastic composite described in this comparative example is that product is made using embodiment 1 in Chinese patent CN106987149B.
Experimental example
By Wood plastic composite made from above-described embodiment 1-4 and comparative example 1-9, according to GB24137-2009, " wood moulding is decorated
Plate " standard carry out bending strength, Deflection Modulus of Elasticity detection.
Antistatic property detection is according to GB/T 1410-2006 " solid insulating material volume resistivity and surface resistivity examination
Proved recipe method "；
The test of surface anti-skidding coefficient is according to professional standard JCT 1050-2007 " ground stone non-skid property grade classification
And test method "；Wherein, it is safe anti-slipping grade that anti-skid factor, which is 0.5-0.79, is incomplete anti-skidding grade lower than 0.5.
Test result see the table below 1.
The performance test results of 1 embodiment of table and comparative example Wood plastic composite
It can be seen that the flexural strength and bending resistance springform of Wood plastic composite product of the present invention from upper table result
Amount performance is all more outstanding, and the surface resistivity of product is substantially all 106On this order of magnitude, wire brush brushing is passed through on surface
Rear surface change in resistance is little, still 106On this order of magnitude, excellent antistatic property can be remain well, and
And the surface anti-skidding coefficient after brushing belongs to safe anti-slipping grade substantially between 0.67-0.72, product of the present invention can
Outstanding counter-bending, surface anti-skidding and antistatic property are taken into account, there is very important application value.
The performance data of scheme can be seen that whole compared to Wood plastic composite of the present invention from comparative example 1-6
For, lack the Wood plastic composite of corresponding necessary component, will appear some corresponding defects, be mainly reflected in bending resistance
The decline of energy and antistatic property；And the adding manner of conductive polyaniline can be to the antistatic property of product in 7 scheme of comparative example
It can also have a significant effect, will lead to conductive polyaniline after being directly granulated and wrapped up, so that the antistatic property of product is reduced, institute
Anti-static function is played to be conducive to conductive polyaniline using addition before taper extrusion molding.
Scheme is using existing ordinary graphite, antistatic agent modeling wood obtained is compound based on metal powder in comparative example 8 and 9
Material, in forming process, graphite, metal powder etc. are easy to migrate to surface, antistatic layer are formed, so smooth surface state
(before the brushing of wire brush surface) surface resistivity is lower, and antistatic property is excellent, and anti-bending strength has larger with product of the present invention
Gap can satisfy the basic demand of general decor Wood plastic composite, be not used to counter-bending more demanding carrying
The fields such as plate, floor；Simultaneously as the anti-skid factor of such product is poor, after wire brush carries out surface brushing, is produced from surface
Raw obvious brushing roughening traces, play the role of anti-skidding, and anti-skid factor can achieve 0.6 or more, but since graphite etc. moistens
Its anti-skid factor of the reason of slip is still below this programme embodiment, and after brushing at this time sheet resistance substantially all 1011More than,
Belong to state of insulation, illustrate that the brush mark to be formed has blocked surface graphite or the mutual electric conductivity of metal powder, and moulds wood
Inner conductive is poor, and therefore, this kind of antistatic modeling wood formula and technique are unable to get counter-bending, surface anti-skidding and antistatic property
The excellent modeling wood products of energy.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
