Abstract

The utility model discloses a wood plastic composite plate material which comprises a wood plastic core layer; the outside of the wood plastic core layer is provided with a composite layer; the composite layer and the wood plastic core layer are tightly combined into a whole; the outer surface of the composite layer is a smooth surface; and the outside of the composite layer is provided with an overlaying layer. The outside of the core layer is provided with the composite surface layer tightly combined with the core layer; the composite surface layer consists of plastic and fillers; the outer surface of the composite surface layer is smooth and flat; the composite surface layer and the core layer are formed by coextrusion and are tightly combined; the edge of the plate is trim and has high tear resistance; the class of the fillers in the surface layer is changed so as to change the color of the plate and improve the performance of the plate; and the wood plastic composite plate has smooth and attractive appearance, strengths the toughness of the plate material and improves the machinable performance.

Description

Mould wood composite board

Technical field

The utility model belongs to the Wood plastic composite technical field, specifically relates to a kind of plastic wood sheet.

Background technology

The Wood plastic composite that utilizes plastics and string to be processed into, be widely used in aspects such as building materials, auto industry, packed and transported, ornament materials and daily life tools, existing plastic wood sheet ubiquity shortcomings such as the surface aesthetic degree is poor, edge tear height, processability difference, has limited its application to a certain extent.

Summary of the invention

It is smooth that the technical problems to be solved in the utility model provides a kind of surfacing, neat in edge, is difficult for tearing, and processability is strong moulds wood composite board.

For solving the problems of the technologies described above, the utility model comprises moulds the reel layer, and its design feature is to mould the reel layer to be provided with composite bed outward, this composite bed with mould the reel layer and be closely as one, its outer surface is a shiny surface.

As to improvement of the present utility model, outside composite bed, be provided with overlay coating.

Because sandwich layer of the present utility model is provided with the composite cover of combining closely with it outward, it can be made up of plastics and filler, and its smooth outer surface is smooth, and it and sandwich layer are co-extruded, both are in conjunction with tight, sheet edge is neat, tearing toughness height, conversion surface layer filling kind, can change the color and the performance of improving sheet material of sheet material, not only smooth in appearance is attractive in appearance, and has strengthened the toughness of sheet material, has improved processability.

Description of drawings

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1 is the end face structure schematic diagram of an embodiment of the utility model;

Fig. 2 is the end face structure schematic diagram of another embodiment of the utility model.

Among the figure 1, sandwich layer, 2, composite bed, 3, overlay coating.

The specific embodiment

By illustrated in figures 1 and 2, the utility model comprises moulds reel layer 1, moulds the outer composite bed 2 that is provided with of reel layer 1, this composite bed 2 with mould reel layer 1 and be closely as one, its outer surface is a shiny surface, the composite bed 2 outer overlay coatings 3 that are provided with.

The reel layer 1 of moulding of the present utility model mixes crowded forming by plastics and string, lignocellulosic material, moulds reel layer 1 outer composite bed 2 and is made up of plastics and filler, and filler can add fire retardant, colorant etc. as required.

Claims

1, a kind of wood composite board of moulding comprises and moulds reel layer (1), it is characterized in that moulding the outer composite bed (2) that is provided with of reel layer (1), this composite bed (2) with mould reel layer (1) and be closely as one, its outer surface is a shiny surface.

2,, it is characterized in that the outer overlay coating (3) that is provided with of composite bed (2) according to the described wood composite board of moulding of claim 1.
