A kind of preparation method of Moisture-proof corrosion-proof wood plastic composite, includes the following steps:
Step 1: vinyon being put into kneader molten plastic mixture, is ground into partial size in 1mm or less after cooling Particle or powder it is stand-by；
Step 2: and then raw material is weighed according to each component parts by weight, and weighed wood powder raw material is placed in heat-treating machine Stir process, until the moisture content in wood powder raw material is 0.5%-3%, the temperature for controlling raw material is 100-180 DEG C；
Step 3: by the wood powder handled well in step 2 put into high-speed mixer in, be added coupling agent, 80 DEG C -110 DEG C with It is interior, it stirs evenly, coupling agent is made sufficiently to wrap up wood powder；
Step 4: and then by ceramic powder, polypropene staple, polyester fiber, glass powdered steel, silicon carbide, nano aluminium oxide The vinyon particle or powder handled well in powder and step 1 are placed in high-speed mixer, are then sequentially added degradable Thermoplastic resin, activated Calcium carbonate, adhesive, adjuvant and foaming agent, mix 5- under the conditions of 75-120 DEG C of temperature 10min, then stirring is cooled to 20-50 DEG C, can obtain premix；
Step 5: the resulting premix of step 4 is placed in temperature is 130-190 DEG C, twin-screw revolving speed is 30-50r/min's It carries out melting in screw extruder and compound wood plastic composite melt can be obtained；
Step 6: wood plastic composite melt obtains Moisture-proof corrosion-proof by squeezing out, after injection, hot pressing or compression molding Wood plastic composite.
Preferably, in step 6, wood plastic composite melt extrusion is formed using conical double screw extruder one-step method, Barrel temperature is 140 DEG C~190 DEG C, and 165 DEG C~195 DEG C of die temperature, die end water flowing is cooling.
Preferably, in step 6, compound, single-screw machine is melted using parallel double-screw extruder or conical double-screw squeezes out Double rank unit one-step method extrusion moldings that machine squeezes out, die temperature are 160~195 DEG C, and die end water flowing is cooling.
