Toughness, expansion rate of water absorption, the detection method of water absorption rate and standard are hit referring in particular to building material industry standard " DB44T349-2006 wood
Plastic composite materials technical conditions " in content.(the template material of embodiment 1-5 is indicated using #1-#5 in following table, comparative example 1-13
Template material using &1-&13 indicate)
Table 7:
Remarks:
1) detection of electromagnet shield effect is carried out on flange shaft tester, test frequency be respectively 1000kHz,
1.5GHz；
2) detection of wet and heat ageing resistant is carried out in hydrothermal aging chamber, and detection temperature is 60 DEG C, humidity
90%RH or more, testing time 168h see whether the bad phenomenons such as cracking, bubbling, geomery variation occur.
Wood plastic composite of the invention is worthy of careful study in raw materials for production selection it can be seen from upper table 7, between raw material
The synergistic effect that assembles make wood plastic composite obtained in the side such as mechanical strength, waterproofness, resistance to oxidation aging and shielding
It is promoted significantly on face, improves the overall performance of wood plastic composite, improve application performance, service life is more secure, tool
There is good promotional value.
In conjunction with the beneficial effect of the present invention, applicant illustrates constituent part and preparation method of the invention as follows:
(1) modification of plant fiber: by having carried out Steam explosion treatment to the high mallow stem hide fiber after being chopped,
The effective loose institutional framework of stem hide fiber, especially improves the institutional framework of amorphous region, eliminates intrastitial fruit
The impurity components such as glue, and the supramolecular structure in cellulose is destroyed, the modified effect of subsequent alkali bubble, elution is enhanced, more
Conducive to the reservation of fibrous mechanical property；Then fiber is put into immersion treatment in lye, can further dissolved in wooden
The low molecules impurity such as part pectin, lignin and hemicellulose, does not change the chemical structure of main fibre element, and rotates fiber
Angle reduces, and molecularly oriented improves, to improve the breaking strength etc. of fiber, above-mentioned alkali cleaning can convenient for subsequent operation it is smooth into
Row；Fiber is put into immersion treatment in organic solvent later, selective wax elution is on the one hand carried out, on the other hand improves wood
Caking property between matter part and polymeric matrix improves the service performance of high mallow stem hide fiber.If in operation at steam blasting
The change of the technological parameter, the type and mass concentration of lye and organic solvent of reason, the modified effect that will lead to fiber have change,
It is unfavorable for the fine realization of beneficial effect of the present invention.
(2) compound coupling agent: the common coupling agent of wood plastic composite has silane series coupling agent, titanate coupling agent, aluminium
Acid esters coupling agent is used to merge organic polymer and inorganic filler reaction, find after many experiments, produces in many coupling agents
The effect that titanate coupling agent 201 generates in being applied to the present invention in product is best, but expected requirement is not achieved, because
This, the coupling agent that applicant attempts to add other ingredients merges with it using and then come reach the purpose of the present invention, herein basis
On, applicant finally surprisingly obtains by three kinds of tin coupled SSBR, titanate coupling agent 201, rare-earth coupling agent ingredients according to matter
Measure than (2-4): (4-8): (1-3) merges obtained compounding coupling agent, and it is very prominent that this kind compounds the beneficial effect that coupling agent obtains
Out, considerably beyond other types and the coupling agent assembled, it can efficiently high mallow stem hide fiber, calcium titanium tail in adhesion promotion raw material
The ingredients such as miberal powder material, villus powder are filled into polymeric matrix, and are improved the physical property of above-mentioned filler and improved protection
The ability that material interface is damaged from environmental stress.If compounding the ingredient of coupling agent or/and the change of content in the present invention,
Will lead to beneficial effects of the present invention cannot realize well.
(3) compound antioxidant: obtaining through applicant's many experiments, antioxidant 1076, antioxidant 1010, antioxidant DSTP
The synergistic effect of three kinds of ingredients can effectively prevent the progress of wood plastic composite chain reaction of the present invention, with excellent smelly
Oxygen cracking and flex crack protective, can preferably promote the environmental stress resistance of wood plastic composite of the present invention, when above-mentioned antioxygen
Ingredient and used time, it not only can be reduced the dosage of antioxidant but also protection effect can be improved, and played respective antioxygen and prevent old advantage, it can be significant
Improve the service life of wood plastic composite；If the change of the ingredient of compound antioxidant or/and content in the present invention, can lead
Cause beneficial effects of the present invention that cannot realize well.
Certainly, because of the requirement of the mentality of designing and goal of the invention of wood plastic composite of the present invention, remaining component of the invention
Selection and content selection are obviously also non-obvious, and those skilled in the art combine the prior art that can think easily absolutely not
It arrives.This has further embodiment in the preparation method of wood plastic composite of the present invention, can see in conjunction with the embodiment of the present invention
It arrives, preparation method of the invention is designed using three steps, and raw material is added in mixing process by several times in batches, and step is simple and has
Sequence, rather than use the prior art is conventional to be added at one time (such as comparative example 12), this technique is and wood plastics composite of the present invention
What the special proportion of material raw materials for production component was adapted, this technique is only used, just can guarantee that wood plastic composite reacts
The smooth sequential of system carries out, and ensures the wood plastic composite excellent characteristics finally prepared.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although referring to aforementioned reality
Applying example, invention is explained in detail, for those skilled in the art, still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features.It is all in essence of the invention
