Abstract

Relating to the field of carton processing, the invention provides a compound adhesive for corrugated cartons. The compound adhesive for corrugated cartons is formed by mixing of a component A and a component B. The component A comprises the following substances by weight percentage: 20-30% of cassava powder, 1-2% of sodium hydroxide, 1-2% of lignin, 0.5-1% of potassium permanganate, 1-2% of ureaformaldehyde resin, 0.1-0.5% of borax, 1-2% of tributyl phosphate, 0.5-1% of glycerol, and the balance water; and the component B includes the following substances by weight percentage: 10-20% of polyvinyl alcohol, 20-30% of formaldehyde, and the balance water. The compound adhesive for corrugated cartons provided by the invention has the advantages of easily purchasable raw materials and simple making process, polyvinyl alcohol is a polyhydroxy polymer, has good film-forming properties and toughness, and under the action of borax, the aqueous solution of polyvinyl alcohol has a porous and water-absorbing surface with strong adhesion and high bonding strength, also use of cassava powder as the raw material can be more secure, economical and environmentally friendly.

Description

technical field [0001] The invention belongs to the field of carton processing, in particular to a composite glue for corrugated cartons. Background technique [0002] At present, the application of corrugated cartons is becoming more and more widespread, and the country's standard requirements for corrugated cartons are also getting higher and higher. The adhesive used for bonding is generally starch glue. Starch glue is characterized by its low price, simple glue making process, and fast drying speed. , can adapt to high-speed production requirements and other advantages are widely used in corrugated paper industry at home and abroad. However, the general starch glue has the following problems. The glue is prone to precipitation during use, easy to mildew and damage during high temperature, and the adhesive performance is not high, which eventually leads to waste of glue in the production process and unstable performance of the cardboard.
