Adhesive for corrugated paper and processing method thereof

Abstract

The invention discloses an adhesive for corrugated paper and a processing method thereof. The adhesive comprises the following raw materials in parts by mass: 10-15 parts of oxidized starch, 15-20 parts of polyvinyl alcohol, 1-3 parts of cooked tung oil, 5-10 parts of silicon resin, 3-5 parts of silicon dioxide, 1-2 parts of isocyanate, 3-6 parts of lactobionic acid, 2-4 parts of magnesium carbonate and 1-2 parts of sodium hydroxide. The processing method comprises the following steps: 1, according to the mass parts, adding the oxidized starch, the polyvinyl alcohol, the magnesium carbonate and the sodium hydroxide into a reaction kettle; 2, and adding the silicon dioxide, the isocyanate and the lactobionic acid into the reaction kettle according to the mass parts; 3) adding the cooked tung oil and the silicon resin into the reaction kettle in parts by mass; 4, cooling the mixture obtained in the step 3 to 10-30 DEG C at normal temperature to obtain the corrugated paper adhesive. The corrugated paper adhesive has the advantages that the strength and the moisture resistance of the corrugated paper are better improved, and the phenomenon of water and adhesive separation is not easy to occur, the bonding strength is high, the bonding property is good, the market use requirements are met, and the product is beneficial to popularization.

Description

technical field [0001] The invention belongs to the technical field of corrugated paper processing, and in particular relates to an adhesive used for corrugated paper and a processing method thereof. Background technique [0002] The invention and application of corrugated paper has a history of more than 100 years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. More than 80% of corrugated paper can be recycled. Corrugated paper It can be used as packaging for food or digital products, which is relatively environmentally friendly and widely used. [0003] When the existing corrugated paper is produced, it needs to be bonded with an adhesive. Commonly used corrugated paper adhesives have weak cohesive force, poor compression resistance, moisture resistance and high temperature resistance, so that the quality of corrugated paper cannot be guaranteed.
