Description

A kind of high-strength corrugated board

Technical field

It the utility model is related to corrugated board technical field, and in particular to a kind of high-strength corrugated board.

Background technology

Corrugated board have in light weight, cost is low, easy processing, the characteristics of being easy to store and transporting, thus be widely used In the extranal packing box of the industrial products such as electronic apparatus, precision instrument.Because electronic product is highly susceptible in transportation Extrude and cause electronic component to deform or damage, therefore when transporting such article, it is necessary to carry out special add to overwrap Strong consolidation process.

Existing corrugated board its corrugated shape for being used to pack is mostly U-shaped or V-type, U-shaped corrugated board it is elastic and viscous Conjunction property is preferable, but compression strength is slightly poor, and V-type corrugated board compression strength is high, but degree of adhesion is relatively low, and elasticity is slightly poor, after deformation It is not easy to recover.Therefore, the corrugated board of single stupefied type can not meet the packaging demand of diversified article, and designer is needed according to not Same packaging demand carries out corresponding stupefied type design.Such as in Chinese patent literature Publication No. CN205344018U utility model In patent, applicant proposed a kind of high strength moistureproof waterproof corrugated board, and outer pressure-bearing is set in the upper surface of fluting medium layer Layer, the corrugated shape of outer bearing course be star, its U-shaped or V-type corrugation cooperation with lower section of star corrugation, improve the resistance to compression of cardboard Bearing capacity, the packaging for breakables such as electronic devices.But found in use is manufactured, the corrugated paper production work of the type Skill is complex, though outer bearing course anti-pressure ability is stronger, not easy processing, production efficiency is relatively low, and the internal layer of corrugated board Elasticity is slightly poor, for valuable frangible electronic instrument or circuit board, it is impossible to play good buffer protection.

Utility model content

The utility model is directed to above-mentioned deficiency, there is provided a kind of high-strength corrugated board different from existing structure, improves The resistance to compression shock-absorbing capacity of corrugated board, the security in increase electronic device transport.

The utility model is achieved through the following technical solutions：

A kind of high-strength corrugated board, including fluting medium layer, the fluting medium layer include upper boxboard, lower boxboard And the corrugating media between upper boxboard and lower boxboard, corrugating media are shaped as U-shaped or V-arrangement, the fluting medium layer Upper surface sets outer bearing course, and cushion in the lower surface setting of fluting medium layer, the outer bearing course includes outer waterproof board With the triangle tube of corrugated paper of outer waterproof board lower floor, the interior cushion includes inner waterproofing cardboard and inner waterproofing cardboard upper strata Circular tube of corrugated paper.The fluting medium layer can need to be designed as one or more layers according to article.

Further, a kind of high-strength corrugated board as described above, the lateral cross section of the triangle tube of corrugated paper are Equilateral triangle, the base of each triangle is parallel with upper and lower boxboard, and the high and outer waterproof board of triangle is apart from upper boxboard Height adaptation.Triangle tube of corrugated paper is arranged using positive and negative alternate, adjacent two triangle tube of corrugated paper side close to each other Fitting.

Compared with existing U-shaped or V-arrangement corrugating media, the corrugating media of outer bearing course uses the triangle of positive and negative alternate arrangement Shape structure, when being collided by external force pressure, there is stronger Compressive Bearing Capacity, effectively protect the article in cardboard because extruding is made Into damage.Preferably, the stupefied peak of the corrugating media and the section triangle base of the triangle tube of corrugated paper of positive arrangement Perpendicular bisector intersects, and corrugated board outer layer can be made to have more preferable anti-pressure ability.

The lateral cross section of the circular tube of corrugated paper is circle, and circular diameter is with inner waterproofing cardboard apart from lower boxboard Highly it is adapted to, adjacent two circular tube of corrugated paper is brought into close contact.Preferably, the stupefied paddy of the corrugating media cuts with circular tube of corrugated paper The vertical diameter of face circle intersects, and corrugated board internal layer can be made to have more preferable shockproof properties.

The outer waterproof board and inner waterproofing cardboard are made up of the cardboard added with waterproof agent, and waterproof agent includes pine Perfume, aluminum sulfate, cationic starch and waterproofing agent.Triangle tube of corrugated paper in the outer bearing course is fine added with PAN bases carbon The high-strength corrugated paper of dimension is made.

The beneficial effects of the utility model are：

1st, the outer surface of corrugated board sets outer bearing course, and outer bearing course uses the triangle corrugated paper of positive and negative alternate arrangement Pipe, equilateral triangle corrugating media easy processing, stability are good, have the ability of the extraneous compressing of stronger carrying, more traditional is U-shaped Or V-type corrugating media bearing capacity enhances more than one times, the electronic article fail in compression in cardboard is effectively protected.

2nd, cushion in the inner surface setting of corrugated board, interior cushion use compact arranged circular tube of corrugated paper, circle Tubular corrugating media uses round roller straight forming, and easy processing, elasticity preferably, have stronger shake-proof ability, effectively alleviates transport During in cardboard article concussion impulsive force, preferably protect in cardboard electronic instrument from external impacts.

3rd, the upper and lower surface of corrugated board uses waterproof board, has the function that Moisture-proof corrosion-resistant, can long-time protection sheet Intralamellar part article is dried, and extends the service life of cardboard, and prevents in cardboard electronic device makes moist to cause short circuit or interface oxygen Change.
