Composite material for paper-like packaging box board, paper-like packaging box board and preparation method thereof

Abstract

The invention provides a composite material for a paper-like packaging box board, a paper-like packaging box board and a preparation method thereof, wherein the composite material is prepared from thefollowing components in percentage by weight: 50 to 70 percent of resin material, 20 to 30 percent of diatomite and 10 to 20 percent of inorganic powder; the inorganic powder comprises 65 to 80 percent of SiO2, 12 to 22.5 percent of Al2O3, 1 to 7.5 percent of Fe2O3 and 1 to 5 percent of K2O. The composite material can improve the ink adsorbability of the product; the composite material is light in weight and strong in oxidation resistance, and the composite material is suitable for producing thin packing box plates; the composite material has the advantages of good toughness, high strength, strong oxidation resistance, no toxicity, no smell, water tightness, moisture resistance, low temperature resistance, light specific gravity of the product, good adsorbability, fast printing speed of watermark and ink, clear patterns, no fading and light quality. The composite material is a green environment-friendly material for replacing the traditional paper box package, the added value of the product is high, and the product can be recycled and reused.

Description

technical field [0001] The invention relates to the field of packaging boxes, in particular to a composite material for a paper-like packaging box board, a paper-like packaging box board and a preparation method thereof. Background technique [0002] Today's packaging boxes have been widely used in many fields. The packaging boxes currently on the market mainly include wooden boxes, cartons, and plastic boxes. Wooden packing box is a packing box made of wooden materials. It is made of solid wood nails. The wooden packing box has good firmness, simple process, easy installation and reliable performance. Moisture, easy to rot, easy to spread plant parasites, methane generated during fumigation is harmful to human health, and wood resources are tight, and supply is difficult; the inner and outer layers of paper packaging boxes are made of paper boards, so not only will they not pollute the environment , and can also be recycled, which greatly reduces the cost, but most of the ...

Problems solved by technology

Wooden packing box is a packing box made of wooden materials. It is made of solid wood nails. The wooden packing box has good firmness, simple process, easy installation and reliable performance. Moisture, easy to rot, easy to spread plant parasites, methane generated during fumigation is harmful to human health, and wood resources are tight, and supply is difficult; the inner and outer layers of paper packaging boxes are made of paper boards, so not only will they not pollute the environment , and can also be recycled, which greatly reduces the cost, but most of the paper packaging boxes are made of corrugated boards, which have relatively poor firmness and poor load-bearing performance. In addition, the cartons are prone to moisture and have a narrow range of use.

The existing plastic packaging box is basically made of polyethylene or polypropylene material, its load-bearing capacity is between the wooden packaging box and the paper packaging box, and the moisture-proof performance is good. The traditional PP + calcium carbonate packaging box is soft. , oil, poor printing effect, and relatively bulky, and only modified PP packaging boxes can be printed with ink, and non-modified PP packaging boxes cannot be printed with ink
