Embodiment 1

[0047] A drop-resistant and deformation-resistant paper packaging box and its preparation process, the specific steps are as follows:

[0048] Step 1: Grafting and modifying the carbon fiber surface;

[0049] Step 2: impregnating the modified carbon fiber with two parts of kraft paper, and hot pressing to synthesize the outer layer 1 and the inner layer 5;

[0050] Step 3: Cutting two high-density polyurethane sponges to obtain outer sponge 2 and inner sponge 4;

[0051] Step 4: blending and modifying high-density polyethylene, compatibilizer, thermoplastic polyurethane, and light calcium carbonate to obtain an intermediate layer matrix;

[0052]Step 5: cutting and grinding the intermediate layer substrate to obtain the intermediate layer 3;

[0053] Step 6: Heat the prepared outer layer 1, inner layer 5, outer sponge 2, inner sponge 4 and middle layer 3 in the order of outer layer 1, outer sponge 2, middle layer 3, inner sponge 4 and inner layer 5. Press and bond to get th...

Abstract

The invention discloses a drop-resistant and deformation-resistant paper packaging box and a preparation process thereof. The packaging box is made of an outer layer, an outer sponge, an intermediate layer, an inner sponge and an inner layer by thermocompression bonding, and the outer layer and the inner layer are impregnated with carbon fiber and kraft paper with surface active groups increased after surface grafted polyurethane treatment, Synthesized by hot pressing, the outer sponge and the inner sponge are high-concentration polyurethane sponges, which have good energy absorption and recovery capabilities, and the middle layer is made of high-density polyethylene, compatibilizer, thermoplastic polyurethane, and light calcium carbonate. . The invention has the ability of anti-tension, anti-drop and anti-deformation, and can more effectively protect the box body and the articles in the box body.

Description

technical field [0001] The invention relates to the technical field of paper products, in particular to a drop-resistant and deformation-resistant paper packaging box and a preparation process thereof. Background technique [0002] At present, there are many kinds of packaging boxes and various materials. There are various packaging boxes such as paper boxes, iron boxes, wooden boxes, and plastic boxes. Each packaging box has its own advantages. The box is beautiful in shape, and the plastic box is convenient and practical. Among them, the paper packaging box is widely used and has a large demand. [0003] As the demand increases, the disadvantages of paper packaging boxes become more and more obvious. Inadvertent drop, extrusion, and stacking during transportation will cause damage to the packaging box and damage the packaged items. The present invention proposes a drop-resistant and deformation-resistant paper packaging box and its preparation process to solve the above-m...
