Abstract
The present invention discloses an anti-cracking wood plastic composite plate, including a rectangular upper fabric layer, a sandwich layer and a lower fabric layer, gridding cloth is buried between the sandwich layer and the upper fabric layer and the sandwich layer and the lower fabric layer, four corner ends of the upper fabric layer, the sandwich layer and the lower fabric layer are provided with notches, anti-cracking end plates are arranged outside two notches located at narrower ends, and two ends of the anti-cracking end plates are provided with pressing plates matched with the notches. The anti-cracking wood plastic composite plate is simple in structure, by arrangement of the anti-cracking end plates, corner ends cracking of the composite plate can be effectively prevented, and the structural strength of the overall composite plate can be improved.
Description
Technical field
The present invention relates to a kind of composite board, relate in particular to a kind of anticracking wood-plastic composite panel.
Background technology
Composite board refers to the sheet material being formed by two kinds or two or more combinations of materials. In fact, for the sheet material of unlike material, the concept of composite board and preparation method are also different. In daily life, often use taking metallic composite panel, wood-plastic composite panel and glass reinforced plastic composite board material as main. Wood-plastic composite panel is mainly after basic material mixes with thermoplastic macromolecule material, processing aid etc. by lignose or other plant cellulose, the high-tech green material of making through die apparatus heating extrusion molding again, have performance and the feature of timber and plastics concurrently, can substitute the composite of timber, plastics and metal.
In use, angle end is easily stressed and ftracture, and finally causes the cracking of whole composite board, has greatly affected overall structural strength for existing wood-plastic composite panel.
Summary of the invention
The object of the invention is to overcome the above-mentioned problems in the prior art, a kind of anticracking wood-plastic composite panel is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of anticracking wood-plastic composite panel, comprise the rectangular-shaped bed of material above, sandwich of layers and the bed of material below, described sandwich of layers and the above bed of material and between the bed of material, be all embedded with grid cloth below, the described bed of material above, sandwich of layers and below four jiaos of ends of the bed of material are provided with breach, and the two breach outsides that are positioned at narrow end are provided with anticracking end plate, and the two ends of described anticracking end plate are provided with the pressing plate coordinating with breach.
Further, the described bed of material above and the below bed of material are to mix extruding by Corvic, wood fibre and composite assistant by proportion by weight to form, and the proportion by weight of wherein said Corvic, wood fibre and composite assistant is 70:20～25:5～10.
Further, described composite assistant comprises plasticizer, stabilizing agent, coupling agent, lubricant and blowing agent.
Further, the granularity of described wood fibre is 80-100 order.
Further, described sandwich of layers is made up of gypsum material.
Further, described anticracking end plate is made up of stainless steel material.
The invention has the beneficial effects as follows:
The present invention is simple in structure, by anticracking end plate is set, effectively prevents the angle end cracking of composite board, has also improved the structural strength of composite board entirety simultaneously.
Brief description of the drawings
Fig. 1 is STRUCTURE DECOMPOSITION schematic diagram of the present invention;
Fig. 2 is use view of the present invention.
Detailed description of the invention
