Problems solved by technology

[0002] As the most important and widely used packaging material, corrugated cardboard has the advantages of light weight, low cost, easy processing, easy storage and transportation, which is not available in wood packaging and metal packaging, while its U, V, UV, etc. The corrugated structure also greatly improves the compression and burst resistance of the carton, but its disadvantage is that the strength of the carton is limited, and its carrying capacity is mainly achieved by increasing the weight of the paper. For heavy-duty packaging products, its mechanical It is difficult to obtain a substantial improvement in performance and carrying capacity
Although the above-mentioned improvement method overcomes the defect of insufficient cardboard strength, the production process is relatively complicated, but it can only solidify the key parts in a targeted manner, and cannot ensure that the overall strength of the carton meets the standard; Difficult processing, high cost, large paper consumption, non-renewable and other problems, cannot be widely used

Embodiment 1

[0025] to combine figure 1 , in the present embodiment, the processing method of fiber-reinforced composite corrugated cardboard is as follows:

[0026] ① The base paper is rolled by corrugating rollers to form corrugations on the base paper, which is called corrugated paper.

[0027] ② The fiber is pressed on the inner side of a layer of cardboard paper in the form of wire, and plastic-paper binder is applied. The plastic-paper binder is a mixture of additives, borax, liquid alkali, corn starch and water, and the mixing mass ratio is additive : Borax: Liquid caustic soda: Corn starch: Water=1:3:5:16:25, the additive is a bridge erecting machine and a stabilizer mixed according to the mass ratio of 1.67:0.33, the borax is industrial borax, and the liquid caustic is The mass percentage is 32% NaOH solution, the cornstarch is food-grade cornstarch; the fiber is high-strength polyester industrial yarn (the manufacturer is Zhejiang Guxiandao New Material Co., Ltd., the model is G...

Embodiment 2

[0033] The setting and working principle of this embodiment are the same as that of Embodiment 1, the difference is that the fiber is nylon, and the fiber is pressed on the inner side of a layer of cardboard paper in the form of a grid, and the grid density is 16-24 holes / m 2 .

Embodiment 3

[0035] to combine figure 1 , in the present embodiment, the processing method of fiber-reinforced composite corrugated cardboard is as follows:

[0036] ① The base paper is rolled by corrugating rollers to form corrugations on the base paper, which is called corrugated paper.

[0037] ② The fiber is pressed on the inner side of a layer of cardboard paper and the core paper in the form of wire, and plastic-paper binder is applied. Among them, the additives in the composition of the plastic-paper binder are bridging machine and stabilizer according to the mass ratio of 1 : 1 mixed, the liquid caustic soda is 30% NaOH solution in mass percentage, and other parameters are the same as the plastic paper binder in Example 1; the fiber is high-strength polyester industrial yarn (Zhejiang Guxiandao New Material Co., Ltd. , the model is GHT-3330 / 384), and its added density is 2 pieces / m 2 , the bonding time is 30 seconds, the bonding temperature is 60°C, and the bonding pressure is 8N...

Abstract

The invention relates to a processing method of a fiber strengthening composite corrugated board and belongs to the technology field of corrugated board processing. The processing method includes the steps of suppressing fiber on a face board paper in a wire rod or gridding mode, applying paper plastic adhesive on the fiber, and then compositing the fiber with a corrugated paper, conducting drying and cooling to finalize the design, slitting, creasing, transversely cutting and stacking. The paper plastic adhesive is mixture of additive, borax, caustic soda liquid, corn starch and water. The processing method of the fiber strengthening composite corrugated board has the advantages of being simple in procedure, convenient to implement, high in intensity of obtained paperboards, good in mechanical property of the obtained paperboards, relatively low in cost, capable of being applied to the fields such as corrugated paperboard processing and the like.

Description

technical field [0001] The invention relates to a processing method of fiber-reinforced composite corrugated cardboard, which belongs to the technical field of corrugated cardboard processing. Background technique [0002] As the most important and widely used packaging material, corrugated cardboard has the advantages of light weight, low cost, easy processing, convenient storage and transportation, which are not available in wood packaging and metal packaging, while its U, V, UV, etc. The corrugated structure also greatly improves the compression and burst resistance of the carton, but its disadvantage is that the strength of the carton is limited, and its carrying capacity is mainly realized by increasing the weight of the paper. For heavy-duty packaging products, its mechanical It is difficult to obtain a substantial improvement in performance and carrying capacity. [0003] At the same time, various packaging objects with special requirements, such as telecommunication...
