Abstract
A lightweight wood-plastic composite board with the woody-texture surface relates to a wood-plastic composite board and mainly solves the problems of poor woody texture, higher density, inconvenience in transport and use, lower bending strength and insufficiency of surface woody texture in existing wood-plastic composite materials. The wood-plastic composite board comprises a foaming wood-plastic composite layer, an upper thin wood plate and a lower thin wood plate, the upper thin wood plate and the lower thin wood plate are arranged from top to bottom, and the foaming wood-plastic composite layer is arranged between the upper thin wood plate and the lower thin wood plate and is fixedly connected between the same. The lightweight wood-plastic composite board is low in density and has real woody texture, is molded at one step, simple in process and high in bending strength. Besides, the lightweight wood-plastic composite board is used for the fields of furniture manufacturing, building decoration, transportation and the like.
Description
Technical field
The utility model relates to a kind of wood-plastic composite panel, is specifically related to the light wood-plastic composite panel that a kind of surface has woodiness touch.
Background technology
Wood plastic composite (wood-plastics composites; Be called for short WPC) be via plastic processing Compound Machining or material that further processes or product by one or more cellulosic materials and one or more thermoplastics; Have anticorrosion, moistureproof, part degradability, environmental pollution is little, cost is low, water imbibition is little, good mechanical performance, anti-aging, advantage such as dimensional stability good, do not ftracture, and the processability of similar wood is arranged again.Application in industries such as building, automobile, indoor and outdoor floor and ornament materials is more and more extensive.Yet the density of wood plastic composite is big (at 0.9～1.05g/cm
3), transportation and use inconvenient operation; Embossing or mode of printing simulation wood grain are adopted in the surface, and woodiness touch is not strong.
The utility model content
The utility model be to solve that existing wood plastic composite woodiness touch is poor, density is bigger than normal, transportation and use operation inconvenience, surface to lack woodiness touch, problem that bending strength is low, provide a kind of surface to have the light wood-plastic composite panel of woodiness touch.
The light wood-plastic composite panel that the utility model surface has woodiness touch comprises the foaming wood-plastic composite layer; The light wood-plastic composite panel that the surface has woodiness touch also comprises veneer and following veneer; Last veneer is provided with up and down with following veneer; The foaming wood-plastic composite layer is arranged between veneer and the following veneer, and is fixedly connected between foaming wood-plastic composite layer and last veneer and the following veneer.
The utility model compared with prior art has following effect:
The utility model is respectively pasted one deck veneer at the upper and lower surfaces of foaming wood-plastic composite layer, makes the surface of the sheet material of formation have woodiness touch, more is prone to accepted by people.The intensity of foaming wood-plastic composite layer own is low, after its surperficial album leave plank, intensity is increased.The bending strength of simple wood plastic composite is 3～6 MPas, and the bending strength of the wood-plastic composite panel of the utility model can reach 8～16 MPas, and density is 0.45～0.8g/cm
3In the time of the wood plastic composite foaming and the top layer veneer bond together, one-shot forming need not secondary veneer processing, preparation technology is simple, pastes firmly.The wood-plastic composite panel of the utility model is compared with simple foaming wood-plastic composite and has both been guaranteed lightweight, has improved intensity again, and has real woodiness touch.
Description of drawings
Fig. 1 is the structural representation of the utility model wood-plastic composite panel, and 1 is last veneer among the figure, and 2 are following veneer, and 3 is the foaming wood-plastic composite layer; Fig. 2 has among the preparation method of light wood-plastic composite panel of woodiness touch the sketch map of the lay in framed of blank before the hot pressing for the surface, 1 be last veneer among the figure, 2 under veneer, 3 is the foaming wood-plastic composite layer, 4 is framed, 5 is finger gauge, 6 is upper cover plate.
The specific embodiment
The specific embodiment one: combine Fig. 1 that this embodiment is described; The light wood-plastic composite panel that this embodiment surface has woodiness touch comprises foaming wood-plastic composite layer 3; The light wood-plastic composite panel that the surface has woodiness touch also comprises veneer 1 and following veneer 2; Last veneer 1 is provided with up and down with following veneer 2, and foaming wood-plastic composite layer 3 is arranged between veneer 1 and the following veneer 2, and is fixedly connected between foaming wood-plastic composite layer 3 and last veneer 1 and the following veneer 2.
This embodiment surface has preparation method's (combining Fig. 2 explanation) of the light wood-plastic composite panel of woodiness touch; Carry out according to the following steps: one, with string powder and thermoplastic powder by mass ratio 40～55: 45～60 mix; Join in the high mixer; Add coupling agent and AC blowing agent again, mix 10min, obtain mixture; Two, the two ends in framed are placed finger gauge to control sheet metal thickness are 8～18mm; Three, be that the veneer of 1～3mm is mated formation in mould with thickness; In the agent of veneer surface sprinkling one deck isocyanates gluing; And then the mixture that obtains of lay step 1, being the foaming wood-plastic composite layer, the thickness of foaming wood-plastic composite layer is 6～12mm; Four, to another Zhang Houdu be surface sprinkling one deck isocyanates gluing agent of the veneer of 1～3mm; Cover then on the foaming wood-plastic composite layer, coated face is downward, contacts with the foaming wood-plastic composite layer; The veneer that is positioned at the upper strata is last veneer; The veneer that is positioned at lower floor covers upper cover plate then for following veneer on framed, obtain completing the mould of blank; Five, the mould of completing blank that step 4 is obtained is put into hot press, and pressure is 4～8MPa, at 175～185 ℃ of condition pressed 5～13min, reduces pressure to 0.3～1.3MPa then, continues hot pressing 2～5min; Six, hot pressing is cooled to 60～75 ℃ of typings after finishing, and then sheet material in the mould is unloaded, and plate surface is carried out sanding, promptly obtains the light wood-plastic composite panel that the surface has woodiness touch; Wherein the quality of coupling agent is 3%～6% of a thermoplastic powder quality in the step 1; The quality of AC blowing agent is 0.5%～1.5% of a thermoplastic powder quality in the step 1.
This embodiment is respectively pasted one deck veneer at the upper and lower surfaces of foaming wood-plastic composite layer, makes the surface of the sheet material of formation have woodiness touch, more is prone to accepted by people.The intensity of foaming wood-plastic composite layer own is low, after its surperficial album leave plank, intensity is increased.The bending strength of simple wood plastic composite is 3～6 MPas, and the bending strength of the wood-plastic composite panel of this embodiment can reach 8～16 MPas, and density is 0.45～0.8g/cm
