Embodiment Construction

[0014] A packaging paper with high folding resistance, which is made of the following ingredients in parts by weight: 3 parts of gypsum whiskers, 6 parts of glycerin, 5 parts of calcium silicate, 100 parts of cedar flour, 3 parts of sodium alginate, 6 parts of polypropylene 25 parts of kelp; it is made by the following production steps:

[0015] 1) Crush the kelp, add it to the reaction vessel, add NaCO3 aqueous solution with a mass percentage concentration of 1.5wt% to the reaction vessel, control the temperature to 95-110℃, continue heating for 1.5-2 hours, filter the residue and leave the filtrate for later use ;

[0016] 2) Physical beating is carried out according to the fir powder and the raw materials prepared in 1). The beating machine performs preliminary beating at a speed of 1000r / min for 2.5 hours. Add gypsum whiskers and calcium silicate, and stir well, then use 2500r The second beating is carried out at a speed of 1.5 hours;

[0017] 3) Carry out centrifugal separatio...

Abstract

The invention discloses high-folding-resistance packaging paper. The high-folding-resistance packaging paper is characterized by being made from gypsum whiskers, glycerol, calcium silicate, fir powder, sodium alga acid, polypropylene and laminaria japonica which are proportioned by weight. The packaging paper has the advantages that raw material resources are wide, reaction is mild, and the packaging paper is free of poison and environment-friendly, and the modern green chemistry concept is met. By adding the gypsum whiskers and the calcium silicate during beating, the tensile strength of the paper can be improved, the strength property of the paper is improved as the pulp beating degree is increased, and the packaging paper can be inked more evenly. By adding laminaria japonica extracts, the flexibility of the paper can be improved, and the strength property of paper sheets made in this way can be improved remarkably.

Description

Technical field [0001] The present invention relates to the field of paper production, in particular to a packaging paper with high folding resistance. Background technique [0002] Paper and cardboard have always been the leading materials in packaging materials, accounting for more than 40% of the packaging materials used. However, the smoothness and printing adaptability of traditional paper and cardboard are relatively low and cannot meet some special occasions. Summary of the invention [0003] The purpose of the present invention is to provide a packaging paper with high folding resistance. [0004] The present invention is realized through the following technical solutions: [0005] A packaging paper with high folding resistance, which is made of the following components in parts by weight: 3 parts of gypsum whiskers, 6 parts of glycerin, 5 parts of calcium silicate, 100 parts of cedar powder, 3 parts of sodium alginate, 6 parts of polypropylene 25 parts of kelp; it is made ...
