Magnesia, is then remixed 10 minutes, and mixture is obtained after being well mixed, standby；
5) by step 4) in obtain mixture input plastics processing mill in, add phosphotriester, barium stearate, dimethyleyelohexane
Amine and 4- trimethyls 1, set the temperature of Plasticator as 185 DEG C, and the time of plasticating, for 30 minutes, then cools down 25 minutes, standby；
6) by step 5) obtain plasticate thing input double screw extruder in, the extruding pelletization at a temperature of 185 DEG C, granulation
It is 3 to extrude compression ratio:1, particle diameter is 3-5mm, obtains wood plastic particles, standby；
7) by step 6) obtained wood plastic particles are put into the mill inframe that spreading machine sets and are mated formation, then will be paved
Material be put into hot press, set the temperature of hot press as 220 DEG C, the pressure value of hot press is 30mpa/cm2, is then carried out
Hot pressing is cured, and then obtains hot pressing wood-plastic board, standby；
8) by step 7) in hot pressing wood-plastic board be made be put into hydraulic press, be passed through 25 DEG C of normal temperature cold water cool down it is fixed
Type, then obtains wood-plastic board of shaping, standby；
9) by step 8) in obtained wood-plastic board cut into slices by size, then trim flash, frosted carries out nothing using survey meter
Fault localization, it is desirable to which surface is without aperture, the defect such as salient point, obtains a kind of having fire-retardant, the wood-plastic board of anticorrosion environment-friendly type.
Experimental example
Experimental subjects：Using wood-plastic board made from the present embodiment 1-3 as experimental group one, experimental group two and experimental group
Three, the wood-plastic board for choosing existing common quality on the market is contrast groups one, and quality preferably special wood-plastic board is contrast groups two.
Object of experiment:Five groups of guardrails are carried out respectively bending strengths, the modulus of elasticity in static bending, 24H water absorption rate, oxygen index (OI) and
The performance test of flame retardant rating, records experimental result.
Experimental method：Five groups of guardrails are carried out to bend by force using the method for testing or professional test instrument of industry internal standard
Degree, the modulus of elasticity in static bending, 24H water absorption rate, the performance test of oxygen index (OI) and flame retardant rating, record test result.
Experimental result table
It can be obtained by experimental result, wood-plastic board of the invention has excellent corrosion-resistant, anti-water suction and fire resistance.
The application method of the present invention：When need by gardens cut-off or will using guardrail to protect flowers, plants and trees when, will first connect
In the threaded access firm banking of ground nail, left column is first hammered into ground by grounding nail after the completion of connection, then will
Guardrail is trailed, and right column is similarly operated with left column, just completes the fixation of guardrail, if necessary to mobile, then needs to exert oneself
By column from ground pull-up, grounding nail is then dismantled, then guardrail is shunk, you can so that guardrail to be moved, volume after contraction
Diminish, convenient transportation.
Beneficial effects of the present invention are：The collapsible guard bar for garden of the present invention, it is simple in construction, it can shrink, install solid
It is fixed convenient, can also at any time it be moved according to design requirement, convenient in carrying, its guardrail body has good fire-retardant, Corrosion Protection.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
The change or replacement expected without creative work, should all be included within the scope of the present invention.
