Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 5.

A corrugated board which is not easy to tear and has high toughness.

The utility model discloses a concrete implementation scheme: including horizontal crease 1 and vertical crease 2, the cardboard is including the first corrugated paper layer 3 that bonds in proper order, grid layer 4, kraft layer 5, non-woven fabrics layer 6 and second corrugated paper layer 7, grid layer 4 comprises polyurethane resin, kraft layer 5 is wavy, grid layer 4 and kraft layer 5 form a plurality of first passageways 8, non-woven fabrics layer 6 and kraft layer 5 form a plurality of second through-holes, all pack rubber rope 101 in first passageway 8 and the second passageway 9, the direction of first passageway 8 and second passageway 9 is the same with the direction of vertical crease 2, rubber rope 101 passes horizontal crease 1, all bond on first corrugated paper layer 3 and the second corrugated paper layer 7 and have plastic film layer 10.

The first corrugated paper layer 3, the grid layer 4, the kraft paper layer 5, the non-woven fabric layer 6 and the second corrugated paper layer 7 are sequentially bonded to form the paperboard, so that the strength and toughness of the paperboard are greatly enhanced, and the paperboard is not easy to tear under the action of external force; the addition of the grid layer 4 and the non-woven fabric which are made of polyurethane resin ensures that the paperboard is not easy to be torn under stress; the plurality of rubber ropes 101 are crossed with the transverse crease 1, so that the strength of the transverse crease 1 is enhanced, the transverse crease 1 is protected, and the transverse crease 1 is not easy to tear under the action of external force; the adhesion of the plastic film layer 10 further increases the toughness of the paperboard, so that the paperboard is not easily torn by force.

Horizontal crease 1 and vertical crease 2 separate the cardboard for a plurality of scraps of paper 11, all be equipped with reinforcement 12 on two adjacent scraps of paper 11 of vertical crease 2, the cross-section of reinforcement 12 is the U form and reinforcement 12 is including the first cardboard 13 that connects gradually, connecting plate 14 and second cardboard 15, connecting plate 14 comprises elastic cloth, the U form groove of first cardboard 13 is inserted to the tip of a scraps of paper 11, the U form inslot of connecting plate 14 is inserted to the tip of vertical crease 2, the U form groove of second cardboard 15 is inserted to the tip of another scraps of paper 11.

When the reinforcing piece 12 is installed on the paperboard, the U-shaped groove of the first clamping plate 13 covers the end part of the paper piece 11 on one side adjacent to the longitudinal crease 2, the U-shaped groove of the connecting piece covers the end part of the longitudinal crease 2, and the U-shaped groove of the second clamping plate 15 covers the end part of the paper piece 11 on the other side adjacent to the longitudinal crease 2, so that the periphery of the end part of the longitudinal crease 2 is covered and protected, and the longitudinal crease 2 of the paperboard is not easy to tear; longitudinal crease 2 and horizontal crease 1 are crossed and extend the cardboard tip and form L form notch with two scraps of paper 11 that longitudinal crease 2 and horizontal crease 1 are relevant, and first cardboard 13 and second cardboard 15 are connected with two scraps of paper 11 respectively, and connecting plate 14 wraps the juncture of longitudinal crease 2 and horizontal crease 1, and then ensures that the difficult atress of cardboard is torn.

Both sides wall in the U-shaped groove of first cardboard 13 all is equipped with first viscose layer 16, all is equipped with second viscose layer 17 on the both sides wall in the U-shaped groove of second cardboard 15.

The end part of the paper sheet 11 is inserted into the U-shaped groove of the first clamping plate 13, and the first adhesive layer 16 is adhered with the paper sheet 11, so that the first clamping plate 13 is fixed on the paper sheet 11; the end part of the paper sheet 11 is inserted into the U-shaped groove of the second clamping plate 15, and the second adhesive layer 17 is adhered with the paper sheet 11, so that the second clamping plate 15 is fixed on the paper sheet 11; this arrangement provides for stable securement of the reinforcing member 12 to the paperboard to facilitate protection of the paperboard.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
