Description

A kind of clipboard

Technical field

The utility model relates to a kind of clipboard, particularly relates to a kind of in light weight, clipboard that price is low.

Background technology

At present, clipboards such as all kinds of blackboards on the market, blank all adopt traditional manufacturing technique production, and plate body is by panel, plate core and bottom plate combined forming, and the board core material material has foamed plastic, glued board, sawdust-board, corrugated sheet, a plastic plate in usefulness at present; Panel material has overlay film white board, cork sheet, plastic plate, galvanized iron sheet, cloth etc.

Adopt plastic plate, glued board, sawdust-board to make the plate core of clipboard, be characterized in surfacing, sturdy and durable, shortcoming is that the plate core costs an arm and a leg, plate body is heavy, clipboard carrying cost of transportation height.

Adopt foamed plastic to make the plate core of clipboard, though foamed plastic is light inexpensive, itself belong to the white pollution material, the degraded difficulty bans use of in developed countries such as America and Europes.

Adopting corrugated sheet to make the plate core of clipboard, is the most general material on the present clipboard market, be characterized in the corrugated sheet moderate cost, light, itself belong to environment-friendly materials, shortcoming is that it lacks intensity, the clipboard of producing is too soft; Corrugated sheet has one-way, surface irregularity, and the glue amount is difficult for smearing evenly during applying glue, dry back easy deformation; And the thickness of corrugated sheet is restricted, and adds to want man-hour multilayer to cohere to piece together thickness, and manufacturing procedure increases, defect rate height in the process.

Summary of the invention

Technical problem to be solved in the utility model be at above-mentioned prior art provide that a kind of in light weight, intensity is big, surfacing, cheap, the clipboard that is easy to reclaim.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this clipboard, include panel, the plate core, base plate, frame, it is characterized in that: described plate core adopts honeycomb cardboard or honeycomb paper core, described panel and base plate adopt fiberboard, or galvanized iron sheet, or plastic plate, or white board, or cloth.

Honeycomb cardboard or honeycomb paper core are the mechanics principle designs according to set, and pass is regular hexagon, and it is big that pressure is born on the surface, in light weight, not yielding; Honeycomb cardboard surfacing, hardness can be compared with sawdust-board, can cohere with iron plate, cardboard, plank, cloth, and is simple to operate; And, itself be environment-friendly materials, thickness can be made according to the thickness of clipboard.

For easy to make, the honeycomb cardboard of above-mentioned clipboard or honeycomb paper core are to be adhesively fixed by glue and panel, base plate.

As further improvement, the frame of above-mentioned clipboard is a plastic frame, and four angles of frame are fixed with the plastics angle, can further alleviate the weight of clipboard.

As preferably, described honeycomb cardboard or honeycomb paper core thickness are in 5～50mm specification, and weight is 110～180 gram/m ²Wherein honeycomb paper core thickness is 0.5～1 centimetre of specification, and 1～5 centimetre of specification of honeycomb cardboard thickness.Described panel and base plate thickness are in 0.5～3mm specification, and weight is 100～700 gram/m ²

Compared with prior art, the advantage that the utility model adopts honeycomb cardboard or honeycomb paper core to make clipboard plate core is: (1) owing to the hollow structure of honeycomb cardboard or honeycomb paper core, clipboard is in light weight, and carrying is simple, saves freight charges; (2) clipboard intensity is big, rigidity is high, and the concora crush intensity of the cardboard of common 5mm thickness (honeycomb hole length of side 6mm) is more than 300kpa; (3) honeycomb cardboard or honeycomb paper core also have performances such as extraordinary buffering, shock insulation, insulation, heat insulation, sound insulation, and the clipboard that adopts honeycomb cardboard to make the plate core all has good quality guarantee from being transported to actual use; (4) all recyclings of honeycomb cardboard or honeycomb paper core belong to ep-type material, meet clipboard international market environmental protection trend; (5) honeycomb cardboard or honeycomb paper core surface are very smooth, and the plate core applying glue that is used for clipboard is easy, and processing is simple; (6) honeycomb cardboard or honeycomb paper core are cheap, and be suitable with the corrugated board price, if make the above clipboard of thickness 1cm, its price also is lower than the corrugated sheet price.
