Glue for bonding corrugated boards and preparation method and application method thereof

Abstract

The invention relates to a glue and a production technology thereof, and specifically relates to a glue for bonding corrugated boards and a preparation method and application method thereof. The gluefor bonding corrugated boards is characterized by comprises a component (A) and a component (B). The component (A) comprises following components in parts by weight: 2 to 3 parts of starch, 10 to 20 parts of water, 0.3 to 0.5 part of caustic soda, 1 to 2 parts of borax, and 0.5 to 0.7 part of water retainer. The component (B) comprises following components in parts by weight: 3 to 5 parts of starch, 25 to 30 parts of water, 0.2 to 0.7 part of caustic soda, 2 to 4 parts of borax, 1 to 3 parts of corrosion inhibitor, 3 to 4 parts of fiber, and 3 to 4 parts of metal slag. The glue has good permeability and high viscosity, and is capable of improving the strength of bonded corrugated boards.

Description

technical field [0001] The present invention relates to a kind of glue and its production process, more specifically, it relates to a kind of glue for bonding corrugated cardboard and its preparation method and application method. Background technique [0002] Corrugated cardboard, also known as corrugated cardboard, is made of at least one layer of corrugated paper and one layer of cardboard paper, which has good elasticity and extensibility. It is mainly used in the manufacture of cartons, the sandwich of cartons and packaging materials for fragile goods. It is made of raw cardboard similar to yellow cardboard by beating straw pulp and waste paper by local methods, and then machined to make the original cardboard roll into a corrugated shape, and then glued on the surface with sodium silicate and other adhesives and boxboard paper. [0003] The quality of corrugated cardboard is related to the temperature, paper web tension, adhesive and the technical level of the operato...

AI Technical Summary

Problems solved by technology

However, because the high-strength corrugated cardboard has good paper quality and high tightness, the capillary pores on the surface of the cardboard are small, and because the general glue has poor permeability, the capillary pores are easily blocked when the glue is applied on the surface of the cardboard, and the glue is difficult to get out of the paper. The surface penetrates into the fiber to form glue nails, so the corrugated cardboard is prone to quality problems such as false sticking, foaming, and degumming. The product quality is unstable and the yield is low, resulting in low productivity. At the same time, corrugated paper and glue waste, higher production costs
