Abstract

A corrugated paper board containing cylindrical corrugated core paper comprises outer layer face paper, corrugated core paper and inner layer face paper, wherein the corrugated core paper at least comprises two layers, one layer of corrugated core paper is V-shaped corrugated core paper, the other layer of corrugated core paper is cylindrical corrugated core paper, core-clamped paper is arranged between two layers of corrugated core paper, a corrugation top of the V-shaped corrugated core paper adopts a flat and straight structure to conglutinate with the outer layer face paper or the inner layer face paper. Compared with common multi-layer corrugated paper boards, the corrugated paper board containing the cylindrical corrugated core paper has the advantages of high buffering performance, high intensity, excellent adhesion strength, low cost and the like, can be used to replace a part of seven layer corrugated paper boards for manufacturing large-scale packaging and transporting corrugated paper boxes.

Description

A kind of corrugated board that contains cylindric corrugating medium

Technical field

The utility model relates to a kind of corrugated board, especially relates to a kind of corrugated board that contains cylindric corrugating medium that is used for transportation and packing.

Background technology

At present, the transportation package holds that generally uses of people has wooden case, multi-wall corrugated board case etc.Wooden case remove cost height, waste big, be difficult for reclaiming, and destroy outside the disadvantage such as the forest reserves, also have shockproof poor, defective such as casing heavy, processing is hard to tackle.

Because corrugated fibre box is compared with the packing container of other materials, have shockproof good, easy manufacturing, can print, in light weight, intensity is high, the advantage of recyclable regeneration, in packaging field, be widely used, as the packed and transported than breakables such as heavy articles and glass, porcelain, handicrafts such as refrigerator, air-conditioner, television set.Corrugated fibre box commonly used is to be made by common corrugated board, and this common corrugated board is by at least two layer plane cardboards and be clipped in two corrugating mediums between the cardboard of plane and form.Because corrugating medium is made by the soft fluting medium of matter, and the compression strength of cardboard is mainly determined by corrugating medium, and therefore common corrugated board compression strength is not good enough, and when vertically standing up pressurized, corrugated board bends distortion easily.If adopt brown paper to make corrugating medium, then cost is too high, and intensity is still not enough.Because corrugated board intensity and corrugated board thickness are directly proportional, for gaining in strength, existing way adds millboard exactly, like this, the casing volume is increased, and has reduced and can utilize the space, has also increased production cost simultaneously.

In transportation, because the shock-absorbing capacity and the shockproof properties of existing packing case do not reach requirement, when packed and transported air-conditioning, refrigerator etc. are than breakables such as heavy articles and porcelain at present, must in case, fill up foamed plastics or other foam lightweight materials, to prevent that article are impaired because of extruding, collision in the case, thereby caused a large amount of white pollutions, and the foamed plastic packing is also by a lot of national nonimportations.

The utility model content

The purpose of this utility model provides a kind of corrugated board that contains cylindric corrugating medium that has high-buffer high-strength simultaneously.

The purpose of this utility model is achieved through the following technical solutions: it comprises outer facial tissue, corrugating medium, nexine facial tissue, corrugating medium is at least two-layer, wherein one deck corrugating medium is a V-arrangement corrugating medium, another layer corrugating medium is cylindric corrugating medium, is sandwich paper between the two-layer corrugating medium; The stupefied top of V-arrangement corrugating medium adopts straight structure and outer facial tissue or nexine facial tissue bonding.

Contact or tangent reinforcement to being provided with along the stupefied of V-arrangement corrugating medium with V-type corrugating medium and sandwich paper.

Described reinforcement is metal rib, bamboo reinforcement bar or plastics (for example PE) rib, or the rib that adopts other string to make.

Compare with existing multilayer transportation and packing cardboard, the reinforcement that is provided with in the utility model corrugated board had both improved the plane compression strength of corrugated board, and cardboard also can bear bigger ambient pressure when standing up.

Straight structure that adopt on the stupefied top of described V-arrangement corrugating medium and outer facial tissue or nexine facial tissue are bonding, both contacts area have been increased, improved bonding effect, avoided separating between existing outer facial tissue or nexine facial tissue and the core paper effectively, also guarantee simultaneously effective transmission of power and vibration between outer facial tissue or nexine facial tissue and the core paper, improved the comprehensive mechanical property of this structure corrugated board.

Described cylindric corrugating medium is made of a plurality of fluting medium bondings cylindraceous, the cylinder-like structure core paper presents level and smooth nonlinear organization, when this structure is subjected to external impacts, the response of impact also can present non-linear, make its distortion a stable region occur, promptly very strong impact only can produce very little distortion, makes cardboard have good shock-absorbing capacity.

Described tubular reinforcement is stupefied to setting along V-arrangement corrugating medium, can strengthen the resistance to compression and the bending strength of cardboard greatly.

Description of drawings

Fig. 1 is the cross-sectional structure schematic diagram of the utility model one embodiment.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

With reference to Fig. 1, the outer facial tissue 1 of present embodiment, nexine facial tissue 6, two-layer corrugating medium, wherein one deck corrugating medium is a V-arrangement corrugating medium 2, another layer corrugating medium is cylindric corrugating medium 5, is sandwich paper 4 between the two-layer corrugating medium; The stupefied top of the V-arrangement corrugating medium 2 between outer facial tissue 1 and the sandwich paper 4 is one section flat arc, and cylindric corrugating medium is positioned at the below of the flat arc of V-arrangement corrugating medium, and is stupefied to being provided with PE reinforcement 3 along the V-arrangement corrugation.

The PE reinforcement 3 that is provided with in the corrugated board had both improved the plane compression strength of corrugated board, and cardboard also can bear bigger ambient pressure when standing up.

The stupefied top of V-arrangement corrugating medium 2 adopts straight structure and outer facial tissue 1 or nexine facial tissue 6 bonding, both contacts area have been increased, improved bonding effect, can effectively avoid separating between outer facial tissue or nexine facial tissue and the core paper, and improve the comprehensive mechanical property of corrugated board.

The cylinder-like structure core paper presents level and smooth nonlinear organization, when being subjected to external impacts, can make cardboard have good shock-absorbing capacity.

The utility model is compared with common multi-wall corrugated board, has that shock-absorbing capacity is good, intensity is high, bonding strength good, low cost and other advantages, can replace seven layers of corrugated board of part to make heavy packages transportation corrugated case.
