Description
Technical field
The present invention relates to a kind of polymer composite, especially a kind of wood plastics composite PVC board.
Background technology
Wood plastics composite PVC board is a kind of composite material being combined by wood powder and resin matrix, can realize wood powder
Scale utilizes.But wood powder and resin matrix are difficult to compatible, another aspect, with the development of science and technology, people's living standard is put forward
Height, " health " and " safety " become the two large problems that contemporary people is paid close attention to the most.Wood plastic composite damping and silencing, soundproof effect
Difference cannot meet consumer health's ecological requirements.
Invention content
Wood powder and resin matrix compatibility, damping can be significantly improved in view of the deficiencies of the prior art, the present invention proposes a kind of
The good damping and silencing of noise reduction, soundproof effect latches Wood-plastic floor preparation method.
The present invention is achieved through the following technical solutions technical goal.
Damping and silencing latches Wood-plastic floor preparation method, thes improvement is that：Include the following steps：
1）Wood powder is mixed with nano oxidized calcium powder by mass parts；
2）Silicone processing aid is added in Wood-plastic foam plate layer and makes Wood-plastic foam plate layer premix；
3）The premix is shaped through conical double screw extruder foam shaping by extrusion, 0 ~ 15 DEG C of recirculated water rapid cooling,
Traction, cutting, are made Wood-plastic foam plate layer；
4）By PVC calendared sheets, decorative pattern film, PVC transparent wear plate from the bottom to top be hot-forming or Continuous Heat composite molding,
PVC transparent wear plate coating UV is glossy to be formed by curing UV coatings；
5）The first resin glue adhesive layer and the second resin glue adhesive layer are formed in Wood-plastic foam plate layer gluing, in the second resin gluing
It closes and bonds PVC composite layers on layer, damping and silencing layer is bonded below the first resin glue adhesive layer, form damping and silencing wood plastics composite
PVC board；
6）Damping and silencing wood plastics composite PVC board is cut into small pieces, the small pieces cut are slotted through groover to be formed public slot and
Female groove.
Further improvement lies in that：The nano oxidized calcium powder is that purity is more than 99%wt, grain size is the super of 300-520nm
Thin lime powder.
Further improvement lies in that：The silicone processing aid is that the super high molecular weight silicone processing without organic carrier helps
Agent.
Compared with prior art, the present invention having the positive effect that：
1, add nano calcium oxide, when lime powder and wood powder carry out mixed at high speed, on the one hand utilize lime powder compared with
Strong water absorption character absorbs the moisture in wood powder；On the other hand, calcium hydroxide is generated after calcium oxide water suction, it is special using its alkalinity
Property, the dissolvings such as the colloid on wood powder surface can be conducive to improve the compatibility and interface cohesion between wood powder and resin matrix
Power.
2, silicone processing aid is added in Wood-plastic foam plate layer, is conducive to the mobility for increasing material, is easy to die formation,
Be conducive to improve the inherent quality and surface smoothness of product.
3, select the ultra-fine calcium oxide powder that purity is more than 99%wt, grain size is 300-520nm as adsorbent, further
Improve the compatibility and interface binding power between wood powder and resin matrix；The gas that calcium hydroxide is generated with azodicarbonamide
CO2Reaction mitigates gas rate of release, improves foaming quality.
4, silicone processing aid is the super high molecular weight silicone processing aid without organic carrier, and lubricant effect is more preferable, into
One step increases the mobility of material, further increases the inherent quality and surface smoothness of product.
Specific implementation mode
With reference to embodiment, the invention will be further described.
Damping and silencing latches Wood-plastic floor preparation method, includes the following steps：
1）Wood powder is mixed with nano oxidized calcium powder by mass parts；
2）Silicone processing aid is added in Wood-plastic foam plate layer and makes Wood-plastic foam plate layer premix；
3）The premix is shaped through conical double screw extruder foam shaping by extrusion, 0 ~ 15 DEG C of recirculated water rapid cooling,
Traction, cutting, are made Wood-plastic foam plate layer；
4）By PVC calendared sheets, decorative pattern film, PVC transparent wear plate from the bottom to top be hot-forming or Continuous Heat composite molding,
PVC transparent wear plate coating UV is glossy to be formed by curing UV coatings；
5）The first resin glue adhesive layer and the second resin glue adhesive layer are formed in Wood-plastic foam plate layer gluing, in the second resin gluing
It closes and bonds PVC composite layers on layer, damping and silencing layer is bonded below the first resin glue adhesive layer, form damping and silencing wood plastics composite
PVC board；
6）Damping and silencing wood plastics composite PVC board is cut into small pieces, the small pieces cut are slotted through groover to be formed public slot and
Female groove.
In the present embodiment, nano oxidized calcium powder is the ultra-fine calcium oxide that purity is more than 99%wt, grain size is 300-520nm
Powder, silicone processing aid are the super high molecular weight silicone processing aid without organic carrier.
