Abstract

The invention discloses an adhesive for a corrugated cardboard and a preparation method, and belongs to the technical field of cardboard manufacturing. The adhesive for the corrugated cardboard comprises, by weight: 30-40% of plant starch, 1-2% of an epoxy resin, 0.1-0.5% of a toughening agent, 0.4-0.8% of a sodium hydroxide solution, 0.5-0.8% of carboxymethyl cellulose, 0.5-1% of an antiseptic, and 0.01-0.02% of ammonium ferrous sulfate, with the balance being water. The adhesive for the corrugated cardboard has advantages of high bonding speed, firm bonding, quick drying, gelation simplicity, and easy and uniform application. The adhesive is simple to prepare and convenient to use; the manufacturing efficiency is high; and the cost is low. The adhesive does not precipitate and mould, and is stable in quality and long in service life. The firmness of the prepared corrugated cardboard can reach 5-6 kg/cm. The invention also discloses a preparation method of the adhesive for the corrugated cardboard.

Description

technical field [0001] The invention relates to a cardboard adhesive and a preparation method, in particular to an adhesive for corrugated cardboard and a preparation method, and belongs to the technical field of cardboard manufacturing. Background technique [0002] During the production process of corrugated cardboard, each layer needs to be bonded together with an adhesive, and its bonding strength is an important indicator for testing the physical properties of corrugated cardboard. In the existing technology, the adhesive used for tiles is generally starch glue. Starch glue is widely used in the corrugated paper industry at home and abroad for its advantages of low price, simple glue making process, fast drying speed, and adaptability to the production requirements of the Soviet Union. . Existing adhesives for corrugated paper have disadvantages such as weak adhesion, easy mildew, short storage period and complicated glue making process, which cannot meet the current p...
