Table 7：Physical property detection
Table 8：Detergent power, antibiotic property and shield effectiveness detection
By upper table 7 and table 8, it can be concluded that, Wood-plastic profiles of the invention are worthy of careful study in raw materials for production selection, raw material Between the synergistic effect that assembles make Wood-plastic profiles obtained in mechanical strength, physical stability, detergent power, antibiotic property and shielding Etc. it is upper promoted significant, overall performance is more excellent, and application is more preferable, and service life is more secure.
In conjunction with the beneficial effect of the present invention, applicant illustrates constituent part and preparation method of the invention as follows：
(1) dispersing agent is compounded：Dispersing agent FT-78, Puli dissipate two kinds of ingredients of PL-80 be combined be applicant accident It obtains, and the combinable enlightenment used is also not present in both dispersing agent products, the two is assembled using the only application National People's Congress Primary trial in amount experiment, but this kind trial but obtains unexpected effect, in the promotion of Wood-plastic profiles performance Want more significant compared to other single compositions and composition dispersing agent, applicant it has been investigated that, dispersing agent FT-78, Puli are dissipated Two kinds of ingredients of PL-80 are (2-3) according to mass ratio:(1-2) merges the dispersion efficiency that obtained composition has strength, can make It obtains filler and the compounding agent degree of being uniformly dispersed greatly improves, accelerate production efficiency, improve properties of product；If being compounded in the present invention The ingredient of dispersing agent or/and the change of content, will lead to beneficial effects of the present invention cannot realize well.
(2) coupling agent is compounded：The common coupling agent of Wood-plastic profiles is mostly silane series coupling agent, is used for organic polymer It reacts and merges with inorganic filler, found after many experiments, silane series coupling agent medium vinyl three ('beta '-methoxy ethyoxyl) silane Using effect is best, but not satisfied enough, and therefore, applicant's trial adds another ingredient and merges using with it and then come Reach requirement, it is finally unexpected to obtain isobutyl triethoxy silane, two kinds of ingredients of anti-settling Aluminate ASA and with obtaining Composite coupler, the beneficial effect that this kind of composite coupler obtains is very prominent, considerably beyond other types and the idol assembled Join agent, it can efficiently in adhesion promotion raw material the ingredients such as Chinese fan palm leaf fibre, niobium yttrium mine tailing, nanometer alum acid bismuth meal material fill to Polymer, the ability that the physical property and protection materials interface for improving above-mentioned filler are damaged from environmental stress.If of the invention The ingredient of middle compounding coupling agent or/and the change of content, will lead to beneficial effects of the present invention cannot realize well.
(3) foaming agent is compounded：It is azodicarbonamide, white it is well known that foaming agent use condition and object are harsher Two kinds of ingredients of foaming agent WBA-T have the foaming capacity of different characteristics, but are used alone to preparation method of the invention In be it is worthless, will lead to the problem of profile foaming effect difference；Applicant is in the characteristic and density feelings for considering material system Two kinds of azodicarbonamide, white hair infusion WBA-T ingredients are dexterously (2-3) according to mass ratio by condition:(3-5) carries out reasonable Proportion, is finally reached the balance of preparation system；If compounding the ingredient of foaming agent or/and the change of content in the present invention, can Cause beneficial effects of the present invention that cannot realize well.
(4) antioxygen anti-aging agent：6- ethyoxyl -2,2,4- trimethyl -1,2- dihyaroquinoline, N- phenyl-N'- isopropyl - P-phenylenediamine, 4,4' a pair of (2,2- dimethyl benzyl) three kinds of ingredients of diphenylamines all have the anti-old oxidation resistant effect of different characteristics Fruit has existed many examples being used alone in the prior art, but these three ingredients are according to mass ratio (1-2):(2-3):Not, and why applicant selects these three ingredients to be worthy of careful study to the example of (2-4), be through Cross what many experiments obtained, 6- ethyoxyl -2,2,4- trimethyl -1,2- dihyaroquinoline thermo oxidative aging performance is strong；N- phenyl- N'- isopropyl-p-phenylenediamine is good to ozone-induced cracking, flex crack protective performance；And 4,4' a pair ofs (2,2- dimethyl benzyl) two Aniline can efficiently promote the environmental stress resistance of all kinds of modeling high molecular products, therefore, prevent experienced point and used time when above-mentioned, both Can be reduced its dosage can improve protection effect again, play respective anti-old anti-oxidant advantage, greatly improve the use of Wood-plastic profiles Service life is quite suitable for the invention material system；If the change of the ingredient of antioxygen anti-aging agent or/and content in the present invention, Will lead to beneficial effects of the present invention cannot realize well.
Certainly, because of the requirement of the mentality of designing and goal of the invention of Wood-plastic profiles of the present invention, remaining component selection of the invention And content selection is obviously also non-obvious, those skilled in the art combine the prior art that can readily occur in absolutely not.This Have further embodiment in the preparation method of Wood-plastic profiles of the present invention, in conjunction with the embodiment of the present invention it can be seen that, the present invention Preparation method using the design of three steps, raw material is added by several times in batches, according to production material property settings technological parameter, step It is simple and orderly, rather than use the prior art is conventional to be added at one time (such as comparative example 10), this technique is and the present invention What the special proportion of Wood-plastic profiles raw materials for production component was adapted, this technique is only used, just can guarantee wood plastic composite The smooth sequential of reaction system carries out, and ensures the Wood-plastic profiles 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 Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
