Abstract
This invention relates to three-layer co-crushing bubble board process method in plastic board materials, which has middle bubble layer and its two surfaces are covered by hard plastic player into one shape.The bubble layer is made by chemical bubble type by use of bubble agent or physical bubble type and uses carbon dioxide or dimethylmethane or butagas as bubble agent for directly into crushing machine. The compound board can be used to make work file, file clamp, file baggage, travel box, etc.
Description
Technical field:
The present invention relates to the plastic plate technical field, refer in particular to a kind of composite plastic plate that is composited by foamed plastic layer and hard plastic layer.
Background technology:
All be individual layer foaming plate or the rigid plastic plate of individual layer at the plastic plate of selling on the market at present, though individual layer foaming plate is in light weight, but case hardness is low, the surface physics poor rigidity, can not resist strong impulsive force, frictional force, the surface is easy to wear, and rough surface, fineness are poor, even can reach bright effect by applying paint or other Surface-micromachining processes, but its form and aspect are still relatively poor; The hardness height of rigid plastic plate can be resisted strong impulsive force, frictional force, also can accomplish smooth surface by Surface Machining, sprays paint back form and aspect, but its density height, often heavy uses inconvenience.
Summary of the invention:
Purpose of the present invention just is to overcome above-mentioned shortcoming.
The present invention is achieved through the following technical solutions: the manufacture method of three-layer co-extruded foaming plate is characterized in that: the middle foaming layer of this three-layer co-extruded foaming plate and the hard plastic layer that is covered with respectively on foaming layer two surfaces, and one-body molded through co-extrusion.
The foaming layer of three-layer co-extruded foaming plate is made by the chemical blowing mode, and with the CBA mixed material, producing density is 0.5g/cm
3～0.8g/cm
3Foaming layer.
The foaming layer of three-layer co-extruded foaming plate is made by the physical blowing mode, as blowing agent, directly squeezes into extruder with carbon dioxide or propane or butane gas, and producing density is 0.6g/cm
3～0.6g/cm
3Foaming layer.
The three-layer co-extruded foaming plate that method provided by the present invention is made, its surface colour lover can make different colours as required, simultaneously can one-shot forming in the middle of production process, reduce production costs greatly.
This three-layer co-extruded foaming plate be used to make document folder, letter file, Germany's folder, a figure shelves bag, suitcase, mutually thin, case lid, storage box or as pharmaceutical packaging material, shock-absorbing with housing material, automobile with ornament materials, food packaging material, structure material or sports equipment.
Description of drawings:
Accompanying drawing 1 is the structural representation of three-layer co-extruded foaming plate
The specific embodiment:
As shown in Figure 1, middle foaming layer of three-layer co-extruded foaming plate (1) and the hard plastic layer (2,3) that is covered with respectively on these foaming layer two surfaces, the thickness of its foaming layer (1) is bigger than hard plastic layer (2,3) thickness separately, and this three-layer co-extruded foaming plate is one-body molded through co-extrusion.
Foaming layer of this three-layer co-extruded foaming plate (1) and hard system plastic layer (2,3) can select to use thermoplastic plastic material to make respectively, and its thermoplasticity material plastic material is polypropylene, polyethylene, polystyrene, the thin ester of ethene acetic acid-second or polyvinyl chloride.
This composite plate foaming layer is also made by the chemical blowing mode, and with the CBA mixed material, producing density is 0.5g/cm
3～0.8g/cm
3Foaming layer.
If desire reduces density less than 0.5g/cm
3Bottleneck, I develop again and can adopt the physical blowing mode, as blowing agent, directly squeeze into extruder with carbon dioxide or propane or butane gas, producing density is 0.6g/cm
3～0.03g/cm
3Foaming layer, make this three-layer composite board weight saving 50%～95%, simultaneously the rigidity on surface still can significantly increase, and the surface establishes the lover, can make different colours as required.
Its foaming layer (1) also can adopt the reclaiming material to make, and not only compliance with environmental protection requirements has reduced cost again simultaneously, is that the composite plate cost greatly reduces.
The three-layer co-extruded foaming plate that adopts said method to make can be used for making document folder, letter file, Germany's folder, a figure shelves bag, suitcase, thin, case lid, storage box or use as pharmaceutical packaging material, shock-absorbing with housing material, automobile with ornament materials, food packaging material, structure material or sports equipment mutually.
