Problems solved by technology

However, polyvinyl alcohol is used as the film-forming agent in the above-mentioned special glue for corrugated paper production line. Although polyvinyl alcohol has good film-forming properties, the moisture-proof performance of corrugated paper after sizing is poor, and the strength of corrugated paper will be greatly reduced after being wet, which will affect the quality of corrugated paper. Normal use

Abstract

The invention discloses glue for corrugated paper. The glue comprises, by weight, 10-30 parts of oxidized starch, 2-5 parts of borax, 2-6 parts of sodium hydroxide, 120-180 parts of water, 50-60 partsof polyvinyl alcohol and 15-25 parts of silicone oil. The glue has the advantages that the glue comprise the oxidized starch, borax and sodium hydroxide, and the oxidized starch after being glued promotes bonding of fiber in the corrugated paper, so that strength of the corrugated paper is improved; the oxidized starch is prepared by oxidizing one of wheat starch, corn starch and tapioca starch,thereby being convenient to obtain, easy to degrade and environment-friendly; polyvinyl alcohol has good film forming performance and forms a flexible film on the surface of the corrugated paper, so that the strength of the corrugated paper is further enhanced; the silicone oil is dispersed in raw materials of the glue, and the corrugated paper after being glued has good moistureproof performance,so that the strength, the moistureproof performance and environment-friendly effect of the corrugated paper are improved; the glue is applied in production of high-strength low-gram-weight corrugatedpaper.

Description

technical field [0001] The invention relates to the technical field of packaging material preparation, in particular to a glue for corrugated paper. Background technique [0002] Among many paper materials, corrugated paper has become an indispensable material for manufacturing packaging containers due to its unique advantages such as light weight, low price, high bending strength, strong processing and structural adaptability, and good printing adaptability. So far, corrugated cardboard has become one of the most widely used packaging materials in modern packaging, and its consumption is still rising steadily. For corrugated packaging materials, people hope that it will have higher strength and be lighter with the same strength, that is, to achieve the effect of high strength and low weight. Products stored in cartons are safer and easier to handle. [0003] In order to meet the high-strength and low-weight requirements of corrugated paper, the corrugated paper industry be...
