Abstract
The utility model relates to a multilayer composite plate, in particular to a multilayer wood plastic composite plate. The multilayer wood plastic composite plate comprises upper and lower layers of wood plastic plates and a high molecular material layer positioned between the two wood plastic plates, wherein the high molecular material layer is an aramid fiber woven mesh. According to the multilayer wood plastic composite plate, the aramid fiber woven mesh is formed between the wood plastic plates; and due to the pull tension of the formed mesh-shaped structure, the upper and lower layers of wood plastic plates are guaranteed to be not easily deformed, the overall mechanical property of the wood plastic plates is improved, and the elasticity modulus of the wood plastic plates is increased.
Description
Technical field
The utility model relates to a kind of multi-layer composite materials, especially a kind of wood-plastic composite panel.
Background technology
With wooden boards, compare, the Wood plastic boards elastic modelling quantity is lower, easily deforms, and whole compressive strength is also undesirable.Particularly under long-term illumination or higher temperature conditions, use, creep easily occurs in Wood plastic boards, affects whole result of use and security.
The aramid fiber full name is " PPTA ", a kind of novel high-tech synthetic fibers, there is superhigh intensity, high-modulus and high temperature resistant, acid-fast alkali-proof, the premium properties such as lightweight, its intensity is 5～6 times of steel wire, and modulus is steel wire or glass fibre 2～3 times, and toughness is 2 times of steel wire, and weight is only 1/5 left and right of steel wire, at the temperature of 560 degree, do not decompose, do not melt.It has good insulating properties and ageing resistace, has very long life cycle.
The utility model content
The utility model provides under a kind of prerequisite that guarantees mechanical strength, effectively reduces creep, improves the multilayer wood-plastic composite wood of elastic modelling quantity.
To achieve these goals, the utility model adopts following technical scheme:
It comprises upper and lower two-layer Wood plastic boards and the polymer material layer between two-layer Wood plastic boards, and its improvement is: described polymer material layer is the aramid fiber mesh grid.
In said structure, described levels Wood plastic boards and aramid fiber mesh grid are hot-forming integrative-structure.
Wood plastic boards of the present utility model is three-decker, intermediate layer adopts the aramid fiber mesh grid, due to cancellated tractive tension force after moulding, the Wood plastic boards that has guaranteed levels is difficult for occurring creep, improved elastic modelling quantity, and network structure has, thickness is little, the structure of porous, can significantly reduce thickness and the quality of Wood plastic boards integral body.
The accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of the utility model embodiment.
In figure: upper strata Wood plastic boards 1, lower floor's Wood plastic boards 2, aramid fiber mesh grid 3.
The specific embodiment
As shown in Figure 1, the multilayer wood-plastic composite wood of the present embodiment comprises upper strata Wood plastic boards 1, lower floor's Wood plastic boards 2 and the aramid fiber mesh grid 3 between two-layer Wood plastic boards.The fusion temperature of wood plastic composite is well below aramid fiber, and after hot pressing is heated, wood plastic composite melts, and aramid fiber keeps original performance.During production, trilaminate material is superimposed, then insert hot press, select suitable heat pressing process, the overstory plastic composite board merges by netted gap and lower floor's Wood plastic boards of aramid fiber, after completing, described levels Wood plastic boards and aramid fiber mesh grid become hot-forming integrative-structure.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
Claims (2)
1. a multilayer wood-plastic composite wood, comprise upper and lower two-layer Wood plastic boards and the polymer material layer between two-layer Wood plastic boards, and it is characterized in that: described polymer material layer is the aramid fiber mesh grid.
2. multilayer wood-plastic composite wood as claimed in claim 1, it is characterized in that: described levels Wood plastic boards and aramid fiber mesh grid are hot-forming integrative-structure.
