Special glue for corrugated paper board production line and preparation method of special glue

Abstract

The invention relates to glue and provides special glue for a corrugated paper board production line, and the special glue has the characteristics of high bonding strength, good permeability, high solid content, low cost, short preparation time and does not need to consume lots of manpower and material resources. Meanwhile, the invention further provides a preparation method of the special glue for the corrugated paper board production line. The preparation method comprises the following steps of: counting in parts by weight, filling 1000+/5 parts of water in a tank body, sequentially adding 6-7 parts of caustic soda flakes, 700+/-5 parts of starch and 1.5+/-0.1 parts of oxidant, and stirring for 28-32 min; adding 800+/-5 parts of water and 13+/-0.5 parts of the caustic soda flakes, and quickly stirring until the viscosity of the glue raises to 11-16 seconds after adding the caustic soda flakes; and adding 4-6 parts of borax, carrying out adequate stirring and uniform mixing, controlling a gelatinization point and maintaining the gelatinization point at 52-55 DEG C, and stopping stirring until the viscosity reaches 13-20 seconds, thereby obtaining the glue.

Description

technical field [0001] The invention relates to a glue, in particular to a special glue for a corrugated cardboard production line and a preparation method thereof. Background technique [0002] At present, the requirements for paper packaging products used in household appliances, precision electronic and electromechanical products, food and medicine, etc. are getting higher and higher. Ordinary packaging cartons, wooden packaging, and EPS packaging are gradually being used by other packaging because their quality and grade cannot meet market demand. product superseded. Due to the advantages of low cost, recyclability, and no pollution, corrugated boxes are widely used in the outer packaging of industrial products. [0003] Adhesives for corrugated cardboard production lines usually use corn starch glue, tapioca starch glue or wheat starch glue. Corn starch glue, tapioca starch glue or wheat starch glue is used to bond cardboard by heating and curing. It requires high te...
