As preferred means, through-hole will be opened up in the middle part of finished section bar after cutting in step 8), then to through-hole and at
Product profile surrounding anticorrosion with painting paint.
Lubricant selects stearic acid, the preferred silane coupling agent of coupling agent, antioxidant choosing compounding phosphorous acid esters, toner
Inorganic pigment is selected, light stabilizer includes hindered amine light stabilizer and ultraviolet absorbing agent.
The invention has the advantages that: one layer of transition zone is equipped between the 1, core material of co-extrusion Wood-plastic profiles, surrounding layer, core material is used
Wood powder makees auxiliary material as major ingredient, polyethylene, and the hardness of timber is big with respect to crops hardness, the melt pelletization together with polyethylene,
Polymerization effect is good, and joined antioxidant, prevents core material from aoxidizing, and oxidation occurs and rots；And the grafting of transition zone maleic anhydride is high
Density polyethylene HDPE-G-MAH has good stretch-proof and shock proof effect, and surrounding layer is greatly improved using modified HDPE
Co-extrusion Wood-plastic profiles wearabilities, resistance to oxidation, increase service life.
2, core material wood plastic layer and transition zone are first subjected to extrusion molding and semi-finished product is made, then beat slot on semi-finished product again
Hole, by modified PS plastic plate thermocompression forming in semi-finished product upper and lower surface, slot makes modified PS plastic plate in conjunction with transition zone
It is stronger；It is punched after cutting finished product, preservation paint, effectively prevent at punching and surrounding is rotted too early.
