Description

High-strength water-resistant corrugated board

Technical Field

The utility model relates to the technical field of paperboards, in particular to a high-strength water-resistant corrugated board.

Background

Corrugated board is a multi-layer adhesive body, which is composed of at least one layer of wavy core paper interlayer (commonly called as "hole paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and one layer of paper board (also called as "box board paper" or "box paper board"). It has high mechanical strength and can resist collision and falling in the process of transportation.

Corrugated container board plays bearing and cushioning effect when in-service use, when suffering the extrusion, can appear warping the damage for buffer capacity receives the influence, simultaneously, owing to belong to paper products, its meet water can influence its holistic intensity greatly after weing.

The present invention is directed to solving, at least to some extent, one of the technical problems in the related art. Therefore, an object of the present invention is to provide a high-strength water-resistant corrugated cardboard, wherein the gaps of the corrugated core paper are filled with particulate fillers to ensure the overall load-bearing and strength, and the paper outside the core paper is waterproof to increase the water resistance.

The technical scheme of the utility model is as follows:

the high-strength water-resistant corrugated board comprises core paper arranged in a wave shape, lining paper is compounded on the outer side of the core paper, at least one group of reinforcing layers are compounded on the outer surface of the lining paper, and filling materials are arranged at the inner side holes of the core paper.

Further, the corrugation height of the core paper is 2.5-5.0 mm.

Furthermore, the two groups of reinforcing layers are arranged, the reinforcing layers comprise outer core paper compounded on the outer surface of the inner paper, and the outer side of the outer core paper is compounded with surface paper.

Further, the corrugation height of the outer core paper is 0.6-2.0 mm.

Further, the filling material is a cutting material of the honeycomb paperboard.

Furthermore, a waterproof paper layer is compounded on the outer side of the corrugated board.

Furthermore, the waterproof paper layer is compounded on the outer side of the surface paper, extends to the side face of the corrugated board and is bent towards the inner paper to be compounded to form a bonding part.

Furthermore, the two bonding parts are arranged in a vertically staggered manner.

Further, the waterproof paper layer is commercially available kraft paper.

The utility model has the following beneficial effects: the corrugated height of the core paper is high, the cushion performance is good, and the strength of the corrugated board can be ensured by matching with the filler at the pore of the core paper; the outer core paper is compounded on the outer side of the inner paper, so that the hardness and the strength of the outer paperboard can be improved; set up waterproof paper layer, waterproof paper layer from corrugated container board side bending to compound with interior paper simultaneously, can guarantee the firm nature of this waterproof paper layer complex bonding, waterproof paper layer and interior paper, the mutual bonding of outside core paper that upper and lower side facial tissue corresponds, corrugated container board's an organic whole nature when guaranteeing its use.
