Its preparation method.
Background technology
As global resources are increasingly exhausted, social environment consciousness is increasingly surging, and timber and petrochemical industry are produced in production and life
Product application proposes higher requirement.Plastic-wood material is as a kind of emerging environment-friendly materials, and it is mainly with plant fiber material
For major ingredient, plastics synthesis is added, a kind of extensive composite of applicability is formed.Due to modeling wood have concurrently plastics Waterproof corrosion and
Two kinds of characteristics of texture of timber so that it turns into a kind of function admirable and very durable outdoor building materials（Floor, fence, bench,
Gardens or waterfront landscape etc.）；Also replace the Wood member that harbour, harbour etc. are used, it may also be used for substitute timber and make various
Packing material, pallet, warehouse pallet etc. are too numerous to enumerate, and purposes is extremely wide.Deserve to be called environmental protection truly, energy-conservation, resource
The novel products of regeneration.
But often because containing more string in plastic-wood material, so that during long-term use, especially
It is that in a humidity environment, plastic-wood material easily causes bacterial growth because moisture is more, so that plastic-wood material goes mouldy
Scrap, and then improve use cost.
Current plastic-wood material also has the deficiency of many aspect of performances, it is impossible to substitute timber completely, makes the sector product

8. the preparation method of radiation proof weather-resistance flame-retardant environment-protecting plastic wood material according to claim 7, it is characterised in that described
Step is：Step one, timber mill leftover bits are added in pulverizer and crushed, cross after 200 mesh sieves the peroxide for adding that concentration is 20%
Change hydrogen solution bleaching, will be dried 2.5 hours at 55 DEG C in the wood powder feeding dryer after bleaching, feeding UV sterilizing chamber disappears
Poison obtains wood powder A in 1.5 hours；
Step 2, wood powder A prepared by step one, eaglewood powder, Corvic, nitrile rubber mixing are added in banbury
90 DEG C are heated to, after being incubated 10 minutes, radiation-resistant glass agent, nano zine oxide, nano titanium oxide, pyrethrins, resistance is added
Agent, ultra-violet absorber, barium zinc stabilizer, antistatic additive, coupling agent, lubricant are fired, 120 DEG C are warming up to, kneads 13 minutes, obtains
To mixture B；
Step 3, mixture B is added in feeding double screw extruder and carries out segmented temperature control extrusion, cooling, pelletizing, segmented
Temperature control divides 6 sections of temperature controls, and temperature is respectively：The temperature of section one is 150 DEG C, and the temperature of section two is 160 DEG C, and the temperature of section three is 170
DEG C, the temperature of section four is 180 DEG C, and the merging area temperature of section five is 190 DEG C, and the head temperature of section six is 195 DEG C, and screw speed is
150r/min, head pressure is 6MPa, and the anti-spoke for cutting off and being invented in cut-to-length machine is added after extrusion profile cooling is qualitative
