Abstract

A method for preparing a corrugated paper binding agent by using corn starch, relating to the technical field of package materials, comprises the following steps of preparing raw materials, wherein the raw materials comprises the following components in parts by weight: the corn starch, caustic soda, high solid catalyst, borax, a de-foaming agent, sodium hypochlorite, water, industrial grade hydrogen peroxide and potassium permanganate; adding water into a reaction still, heating to 60 to 70 DEG C, then adding the corn starch, and uniformly stirring for 3 to 5 minutes for gelatinization; dissolving the sodium hypochlorite, the hydrogen peroxide and the potassium permanganate with 5 to 10 times of water, and adding into the reaction still for stirring for 5 to 20 minutes; dissolving the caustic soda with 3 to 5 times of cold water, adding into the reaction still, and stirring for 20 to 40 minutes; dissolving the borax and the de-foaming agent with 6 to 10 times of boiled water, adding into the reaction still, stirring for 3 to 5 minutes, and standing for 2 to 4 minutes; adding the high solid catalyst into the reaction still and uniformly stirring. The method provided by the invention has the advantages that the formula process is novel, the raw material cost is low, the production period is short, and the binding agent quality is good.

Description

[0001] Technical field: [0002] The invention relates to the technical field of packaging materials, in particular to a method for making corrugated paper adhesives from cornstarch. [0003] Background technique: [0004] Packaging cardboard is the general term for cardboard used for packaging. Including white cardboard, yellow cardboard, kraft cardboard, corrugated cardboard, etc. It is generally required to have strong folding resistance and good flexibility. It is made of wood, rice straw, etc., pulped by different methods, and copied on a cardboard machine. It is mainly used to make packaging cartons, and also used as packaging materials or printing materials. Packaging cardboard has the characteristics of light weight and convenience, but its strength is low, it is easy to crack, and its waterproof performance is poor. However, the existing starch-made cardboard bonding additive method is relatively simple, the time required for production is long, and the process is ...
