Abstract

The utility model discloses a vegetable fiber paperboard, belongs to a packaging material, and aims at providing a paperboard for packaging a paper box, which is simple in structure, convenient to manufacture, and little in paper usage amount. The vegetable fiber paperboard comprises a surface paper and a bottom paper; and a vegetable fiber felt (2) is adhered between the surface paper (1) and the bottom paper (3). The vegetable fiber paperboard has the advantages of simple structure and low cost, is convenient to manufacture, and the technical indexes such as compression strength, breaking strength and tear strength and the like are superior to those of a corrugated paperboard, so the vegetable fiber paperboard serves as an ideal material for manufacturing and packaging the paper box.

Description

The plant fiber paper coverboard

Technical field: the utility model relates to a kind of packaging material, relates in particular to a kind of paper coverboard that is used to make Packaging Box.

Background technology: well-known, the paper coverboard that is used to make Packaging Box at present is mainly corrugated board; It is made of surface layer paper, bottom paper and one or more layers corrugated paper of being bonded between the two layers of paper.Though this corrugated board structure is fairly simple, consume a large amount of corrugated papers, and the increase of paper demand not only can consume the great amount of water resources and the energy but also can aggravate environmental pollution.

Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of simple in structure, easy to make, plant fiber paper coverboard that paper using amount is few.

To achieve these goals, the utility model by the following technical solutions: it comprises surface layer paper and bottom paper; Between surface layer paper and bottom paper, be bonded with the string felt.

Compared with the prior art, the utility model substitutes traditional corrugated paper owing to adopted technique scheme with the string felt, therefore can reduce the consumption of paper significantly, thereby can alleviate the pollution that paper industry is brought to environment.The utility model not only has simple in structure, easy to make, low cost and other advantages, and technical indicators such as compression strength, rupture strength and tear resistance all are better than corrugated board.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Among the figure: surface layer paper 1 bottom paper 3 string felts 2

The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

As shown in Figure 1: between surface layer paper 1 and bottom paper 3, be bonded with string felt 2.

Preparation method: roll, rub diffusing with the machinery plant that fiber contents such as straw, stalk is high, make fiber separation; Will to be cut into bar along machine direction directly be 0.5～1.5 millimeter strip through rolling, rub diffusing plant, then by conveyer belt with the plant of slitting shape send into meshed gears roll bend to wavy; Should be paved into fluffy and the uniform string felt 2 of thickness by wavy plant with the mode of spraying, the obverse and reverse to this string felt evenly sprays bonding agent then; There have the surface layer paper 1 of bonding agent and bottom paper 3 that the positive and negative of this string felt are covered with roller coating to be bonding, forms the paper coverboard; Utilize conveyer belt that this paper coverboard is sent in the typing forcing press at last and be depressed into predetermined thickness, pressurize, oven dry are solidified until bonding agent.The utlity model has and to carry out processing such as impression, bending, otch, bookbinding as required, can replace present widely used corrugated board fully.In addition, the utility model also can be as required, kind of the fiber density degree of string felt 2, resin added, bonding agent etc. regulated, thereby obtain the paper coverboard of varying strength.

Claims

1. a plant fiber paper coverboard comprises surface layer paper and bottom paper; It is characterized in that: between surface layer paper (1) and bottom paper (3), be bonded with string felt (2).
