Abstract
The utility model discloses a composite low-foamed plastic board, belonging to the field of plastic boards. The utility model is composed of two a base layer 2. The utility model is characterized in that the base layer is a low-foamed plastic board, and the surface of the base layer is combined together with a non-foamed surface layer 1. The utility model has the advantages of firm combination of the surface layer, high strength, no water absorption, anticorrosion, mildewproof property, fire retardation, smooth surface, etc. The utility model can be widely used on kitchen ware, furniture, office accommodation, decoration, etc.
Description
The utility model relates to a kind of low foaming plastic sheet material, belongs to the plastic plate technical field.
It is low that existing plastic plate has intensity, poor fire, and fineness is low, easily the deficiency of cut.
The purpose of this utility model is, a kind of intensity height is provided, and fire resistance is good, and inside and outside layer is in conjunction with firmly, any surface finish, low foaming plastic sheet material attractive in appearance.
The purpose of this utility model reaches by the following technical programs.This low foaming plastic sheet material is made up of basic unit 2, and its special character is, basic unit 2 is the low foaming plastic material, and its one side is provided be the do not foam top layer 1 of one compound with it.
One of preferred version is, is provided be the do not foam top layer 3 of one compound with it at the another side of basic unit 2.
Two of preferred version is, establishes dovetail groove 4 at the upper surface of basic unit 2, and the top layer 1 of not foaming is inlayed with basic unit 2 by this dovetail groove and is connected.
Three of preferred version is, is provided with dovetail groove 4,5 on upper and lower two surfaces of basic unit 2, and the top layer 1,3 of not foaming is inlayed with basic unit 2 through dovetail groove 4,5 respectively and is connected.
The thickness on top layer 1,3 is 1-30mm.
Because basic unit of the present utility model is a low foamed material, the top layer is expanded material not, the two mold pressing when molten condition is an one, makes it compared with prior art, has basic unit in conjunction with firm, in light weight, the intensity height does not absorb water, anticorrosion, mildew-resistant, fire-retardant, smooth surface, advantages such as easy scouring can be widely used in kitchen tools, furniture, office accommodation, decoration etc.And the top layer can directly be processed into versicolor colour table, grain board or various patterns in the printing of top layer as required.
The explanation of accompanying drawing drawing:
Fig. 1-a kind of structural representation of the present utility model;
Fig. 2-another kind of structural representation of the present utility model;
Fig. 3-the third structural representation of the present utility model;
Fig. 4-the 4th kind of structural representation of the present utility model.
Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.
Embodiment 3, with reference to figure 3.This is to establish dovetail groove at basic unit's 2 upper surfaces, a kind of compound low foaming plastic sheet material on band top layer 1.Basic unit 2 is low foaming PP material, and top layer 1 is the PC material.With double screw extruder two-shipper coextrusion mold the time, a double screw extruder has formed the basic unit that is with dovetail groove on the face, then compound again upper epidermis 1 naturally in the process of extruding basic unit 2.The sheet material of this structure, basic unit combines more firm with the top layer, therefore, to the range of choice broad of material.
Embodiment 4, with reference to figure 4.This is all to establish dovetail groove on basic unit 2 upper and lower surfaces, and is compounded with the low foaming plastic sheet material on 1 top layer 3, top layer respectively.Basic unit 2 is low foaming PE material, and top layer 1,3 is the PE material that do not foam.As embodiment 3, with two double screw extruder coextrusion molds the time, extrude in the process of basic unit 2, formed upper and lower surface naturally all with the basic unit of dovetail groove, then compound upper epidermis 1,3 simultaneously again.
Claims (4)
1, a kind of compound low foaming plastic sheet material, it is made up of basic unit (2), it is characterized in that, and basic unit (2) is the low foaming plastic material, and its one side is provided with the top layer of not foaming (1) of one that is compound with it.
2, by the described compound low foaming plastic sheet material of claim 1, it is characterized in that, be provided be the do not foam top layer (3) of one compound with it at the another side of basic unit (2).
3, by the described compound low foaming plastic sheet material of claim 1, it is characterized in that, establish dovetail groove (4) at the upper surface of basic unit (2), the top layer (1) of not foaming is inlayed with basic unit (2) by this dovetail groove and is connected.
4, by the described compound low foaming plastic sheet material of claim 2, it is characterized in that, be provided with dovetail groove (4), (5) on upper and lower two surfaces of basic unit (2), do not foam top layer (1), (3) are inlayed with basic unit (2) through dovetail groove (4), (5) respectively and are connected.
