Abstract
The invention discloses a plastic-wood co-extruded plate. The plastic-wood co-extruded plate comprises a center layer and a surface layer, wherein the surface layer is a high-density polyethylene (HDPE) surface layer to which a wood fiber material is added; the formulation of the surface layer comprises 25-30 parts of HDPE plastic, 30-50 parts of wood fiber material, 10-15 parts of filler, 2-5 parts of coupling agent, 0.5-1 part of ultraviolet absorbent, and 0.2-0.5 parts of main and auxiliary antioxidant; the center layer is a plastic-wood plastic center layer; the center layer is extruded and molded by a main extruder; and the surface layer is extruded through a co-extruder to coat the outer surface of the entire center layer. The co-extruded plate not only has good wood texture, but also greatly enhances the weather fastness and the ageing resistance; the surface can be polished and napped, and the color has good stability.
Description
Technical field
The present invention relates to a kind of sheet material, this sheet material can be used as floor or wallboard, refers to especially a kind of wooden co-extrusion plate of moulding.
Background technology
At present, co-extrusion floor/wallboard of the prior art generally comprises central core and top layer, the top layer is pure plastics, central core is that plastic wood is moulded central core, skin depth 0.1-0.5mm, the shortcoming of this co-extrusion floor is: do not have woodiness touch, and the top layer can not do post-processed, such as polishing, plucking etc. 1.; 2. the colour stability of the weatherability of this sheet material, ageing resistance and product is inadequate.
Summary of the invention
Technical problem to be solved by this invention is: a kind of wooden co-extrusion plate of moulding is provided, and this co-extrusion plate not only has good woodiness touch, and has strengthened weatherability, ageing resistance, and can polish in the surface, plucking is processed, and colour stability is good.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind ofly mould wooden co-extrusion plate, comprise central core and top layer, described top layer is the HDPE top layer that is added with wood fiber material, and the prescription on described top layer is: 25～30 parts in HDPE plastics; 30～50 parts of lignone materials; 10～15 parts of fillers; 2～5 parts of coupling agents; 0.5～1 part of ultraviolet absorber; 0.2～0.5 part in major-minor antioxidant; This central core is that plastic wood is moulded central core, and this central core is by the main extruder extrusion molding, and the external surface that coats whole central core is extruded on described top layer by co-extrusion machine.
As a kind of preferred scheme, described wood fiber material is one or more in wood powder, bamboo powder, the rice chaff, and the particle diameter of this wood fiber material is the 60-80 order.
As a kind of preferred scheme, the thickness on described top layer is 1mm-2.5mm.
As a kind of preferred scheme, the upper surface on described top layer is waveform.
As a kind of preferred scheme, described central core is solid central core.
As a kind of preferred scheme, described central core is hollow central core, and this central core comprises several holes, and the thickness of the interior muscle that each hole is cut apart is 4mm-5mm, and described top layer external surface is 5mm-6mm to the thickness between the internal surface of hole.
After having adopted technique scheme, effect of the present invention is: because described top layer is the HDPE top layer that is added with wood fiber material, the prescription on described top layer is: 25～30 parts in HDPE plastics; 30～50 parts of lignone materials; 10～15 parts of fillers; 2～5 parts of coupling agents; 0.5～1 part of ultraviolet absorber; 0.2～0.5 part in major-minor antioxidant; This central core is that plastic wood is moulded central core, this central core is by the main extruder extrusion molding, the external surface that coats whole central core is extruded on described top layer by co-extrusion machine, therefore, in HDPE, add wood fiber material in the top layer, given this co-extrusion plate stronger woodiness touch, improved weatherability, the ageing resistance of product, the colour stability on surface is good, surface texture intensity height, waterproof, anticorrosion, can polish, the plucking processing.Therefore central core, can directly carry out co-extrusion with reclaiming waste material owing to do not contact with the external world in addition, does not need to carry out after-treatment to reclaiming waste material, has avoided secondary pollution.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structure sectional view of the embodiment of the invention;
In the accompanying drawing: 1. top layer; 2. central core; 3. hole; 4. interior muscle.
The specific embodiment
The present invention is described in further detail below by specific embodiment.
Embodiment 1
As shown in Figure 1, a kind ofly mould wooden co-extrusion plate, comprise central core 2 and top layer 1, this central core 2 is moulded central core 2 for plastic wood, according to client's needs, central core 2 can be solid or hollow, when hollow, this central core 2 comprises several holes 3, and the thickness H1 of the interior muscle 4 that each hole 3 is cut apart is 4mm,, described top layer 1 external surface is 5mm to the thickness H2 between 3 inner surfaces of hole.
Described top layer 1 is for being added with the HDPE top layer 1 of wood fiber material, and the prescription on described top layer 1 is: 25 parts in HDPE plastics; 50 parts of lignone materials; 15 parts of fillers; 2 parts of coupling agents; 0.5 part of ultraviolet absorber; 0.2 part in major-minor antioxidant; Interpolation pigment that as required can be suitable, with the mentioned component mixing granulation and send in the co-extrusion machine, the raw material mixing granulation that plastic wood is moulded in the central core is sent in the main extruder, this central core 2 is by the main extruder extrusion molding, and the external surface that coats whole central core 2 is extruded on described top layer 1 by co-extrusion machine.The optimum thickness H3 on described top layer 1 is 2.5mm, and too thick, product cost has drawn high, too thin post processing rear center layer will expose, and wherein, the upper surface on top layer 1 refers to the surface that this co-extrusion plate exposes after installing, accordingly, another plane relative with upper surface then is soffit.As required, the upper surface on described top layer 1 is waveform or other decorative patterns, can enrich the type of co-extrusion plate.
Structure among this embodiment is identical with embodiment 1, and just, the thickness H1 of interior muscle 4 is 6mm,, described top layer 1 external surface is 6mm to the thickness H2 between 3 inner surfaces of hole.The prescription on described top layer is: 30 parts in HDPE plastics; 30 parts of lignone materials; 10 parts of fillers; 5 parts of coupling agents; 1 part of ultraviolet absorber; 0.5 part in major-minor antioxidant; The optimum thickness H3 on described top layer 1 is 2mm.
The every test data of this co-extrusion plate such as following table:
