Calcium-plastic high-intensity corrugated paper and preparation method thereof

Abstract

The invention discloses calcium-plastic high-intensity corrugated paper which consists of a corrugated layer and a plastic layer, and is prepared from the following raw materials in parts by weight: 200 to 400 parts of waste newspaper, 80 to 110 parts of wheat straws, 80 to 120 parts of paper mulberry barks, 100 to 160 parts of modified corn starch, 50 to 70 parts of graphene, 60 to 80 parts of borax powder, 40 to 56 parts of sodium bentonite, 30 to 36 parts of potassium permanganate, 21 to 35 parts of aluminum hydroxide, 20 to 30 parts of sodium carbonate, 11 to 27 parts of ammonium persulfate and 20 to 30 parts of calcium carbonate; and the plastic layer is prepared from the following raw materials in parts by weight: 40 to 60 parts of polyvinyl chloride, 21 to 27 parts of phenolic resin, 11 to 17 parts of industrial alcohol, 3 to 7 parts of methylbenzene, 13 to 19 parts of titanium dioxide and 14 to 22 parts of N,N-dimethyl benzylamine. The calcium-plastic high-intensity corrugated paper is uniform in thickness, high in water resistance, high in buffer property and convenient to recycle.

Description

technical field [0001] The invention relates to a calcium-plastic high-strength corrugated paper and a preparation method thereof. Background technique [0002] In our country, most of the existing corrugated cardboard production lines use corn starch binder. The diameter of corn starch particles is 4-50um, and its composition is mainly glucose carbohydrates, accounting for about 20% in corn steep liquor, and the rest is water and a small amount of additives. Starch itself is insoluble in water. Starch will expand in volume as the temperature rises in water. After expansion and rupture, it will dissolve into a paste with water and become a viscous liquid. During the bonding process of cardboard, it will penetrate into the surface of the adherend In the hole, after the water evaporates, a physical and mechanical adhesion with a certain network crosslinking is formed. Its advantages are non-toxic, non-corrosive, non-polluting, wide source of raw materials, simple manufacturi...

AI Technical Summary

Problems solved by technology

However, there are very few adhesives suitable for the bonding of calcium-plastic sheets and paper, so it is necessary to study new, efficient, and pollution-free adhesives for calcium-plastic corrugated paper

[0004] Therefore, in summary, the existing corrugated paper has the problems of uneven thickness, poor waterproof performance, poor cushioning performance, and difficult recycling.
