A kind of production technology of starch glue

Abstract

The invention discloses a production process of starch glue. The starch glue is prepared from the following raw materials in parts by weight: 850-1200 parts of water, 130-170 parts of raw starch, 2.2-3.2 parts of solid potassium permanganate, 11-16 parts of caustic flakes and 10-14 parts of borax. The components of the raw materials as well as relationship between the raw materials and the environmental temperature are limited, so that the finally formed product has the beneficial effects of good stability and high yield. Moreover, the raw materials play to one another and are matched with one another, so that no deformers, enhancers or other enhancer, stabilizers and bridging agents are added to stable the stability of the starch glue, the raw materials are reduced, and the product has remarkable economic benefit and environmental effect.

Description

technical field [0001] The present invention relates to a glue used in the manufacture of corrugated cardboard boxes, book binding and the like. More specifically, the present invention relates to a process for the production of starch glues used in the manufacture of corrugated cardboard boxes, book bindings and the like. Background technique [0002] Existing starch glue products are used in the manufacture of corrugated cardboard boxes, gluing of postage stamps, wood processing, book binding, and the gluing of paper. It has the beneficial effects of low price, convenient use and no poison. [0003] Specifically, the raw material formula of traditional starch glue usually includes: hydrogen peroxide / sodium hypochlorite, water, caustic soda, borax, starch, reinforcing agent, defoamer, adhesive, etc. In this traditional production process, there are the following defects. Using hydrogen peroxide as an oxidant will generate a large amount of foam during the oxidation reacti...

AI Technical Summary

Problems solved by technology

In this traditional production process, there are the following defects. Using hydrogen peroxide as an oxidant will generate a large amount of foam during the oxidation reaction. If physical defoaming or defoaming agents are used for defoaming at the same time, one of the situations that occurs is defoaming. The effect is not good. The other is that the dosage is not easy to control and is not environmentally friendly. Using sodium hypochlorite as an oxidant is very harmful to the human body, especially to the eyes of the operator, and under the compounding of the temperature, the chlorine content is reduced. Therefore, use hydrogen peroxide and Sodium hypochlorite is used as an oxidant, which has unstable factors, is not environmentally friendly, and has potential safety hazards during use. At the same time, it needs to add a reinforcing agent or glue to enhance its adhesion during the production process to ensure the stability of the later product.

[0004] In addition, in the traditional production process, the addition of caustic soda and borax solution is all added at one time. For the one-time addition of caustic soda solution, the temperature generated during its dissolution often makes the starch in direct contact with it agglomerate quickly and become solid, resulting in It causes serious damage to the quality stability of the late product. For the one-time addition of the borax solution, because it usually dissolves in boiling water, to ensure its dissolution effect, but directly adding it in one time after the boiling water dissolves will also cause its damage to the product. Quality stability causes severe damage
