Embodiment 1

[0014] Example 1: At room temperature, mix 35kg of cornstarch with 40kg of water, slowly add and stir until milky white starch slurry is obtained, and 8kg of sodium hydroxide is prepared into a certain concentration of sodium hydroxide solution and slowly added to the starch slurry , to obtain pre-gelatinized milky white sticky starch paste; then take 0.3kg of potassium permanganate and 0.9kg of phosphoric acid, use hot water to prepare a certain concentration of composite oxidant solution, add in the above-mentioned starch paste; then take 0.15kg of boric acid and heat Dissolve in water to make a certain concentration of solution, add starch paste to form a glue, finally take 0.15kg of sodium bicarbonate and 0.05kg of alum to prepare a certain concentration of solution, add it to the glue to finally obtain an oxidized starch adhesive, and keep the adhesive Stir and slowly add 0.25 kg of nano sepiolite powder to finally obtain a finished product.

Embodiment 2

[0015] Example 2: At room temperature, mix 45kg of cornstarch with 55kg of water, slowly add and stir until milky white starch slurry is obtained, and 10kg of sodium hydroxide is prepared into a certain concentration of sodium hydroxide solution and slowly added to the starch slurry , to obtain pre-gelatinized milky white viscous starch paste; then take 0.45kg of potassium permanganate and 3.15kg of phosphoric acid, use hot water to prepare a certain concentration of composite oxidant solution, add in the above-mentioned starch paste; then take 0.25kg of boric acid and heat Dissolved in water to form a solution of a certain concentration and add starch paste to form a glue, finally take 0.25kg of soda and 0.20kg of alum to make a solution of a certain concentration, add it to the glue to finally obtain an oxidized starch adhesive, and keep the adhesive Stir and slowly add 0.25 kg of nano sepiolite powder to finally obtain a finished product.

Embodiment 3

[0016] Example 3: At room temperature, mix 40kg of cornstarch with 45kg of water, slowly add and stir until milky white starch slurry is obtained, and 9kg of sodium hydroxide is prepared into a certain concentration of sodium hydroxide solution and slowly added to the starch slurry , to obtain pre-gelatinized milky white sticky starch paste; then take 0.35kg of potassium permanganate and 1.25kg of phosphoric acid, use hot water to prepare a certain concentration of composite oxidant solution, add in the above-mentioned starch paste; then take 0.18kg of boric acid and heat Dissolved in water to make a certain concentration solution, add starch paste to form a glue, finally take 0.2kg of soda and 0.18kg of alum to make a certain concentration solution, add it to the glue to finally obtain the oxidized starch adhesive, and keep the adhesive Stir and then slowly add 0.3kg of nano sepiolite powder to finally obtain a finished product.

Abstract

The invention discloses a multi-effect adhesive for corrugated cartons. The multi-effect adhesive is made from raw materials in parts by weight as follows: 35-45 parts of corn starch, 40-45 parts of water, 8-10 parts of sodium hydroxide, 0.15-0.25 part of boric acid, 1.2-3.6 parts of a compound oxidizing agent, 0.15-0.25 part of sodium thiosulfate, 0.25-0.4 part of nano sepiolite powder and 0.05-0.20 part of alum. The multi-effect adhesive has the advantages that the adhesive is quick in drying and good in adhesiveness, the phenomena of moisture absorption and efflorescence cannot appear easily, and the adhesive is particularly suitable for adhesion of the corrugated cartons.

Description

technical field [0001] The invention relates to a starch adhesive, in particular to a composite adhesive used for bonding corrugated cartons. Background technique [0002] In the production of paper products, especially corrugated boxes, natron has been used for decades. Because it is highly alkaline and easy to absorb moisture, it often returns to alkali and whitens, causing paper products to deform, peel off, and even corrode products, resulting in huge economic losses such as deterioration and scrapping. Therefore, starch adhesives have been used to replace natron in foreign countries since the 1950s, and starch adhesives have been studied in China since the end of the 1970s, and gradually popularized in the production of paper products in the 1980s. [0003] There are many disclosures about the formulation and production process of starch adhesives in the prior art, among which there are hundreds of patent technical documents found on the website of the State Intellectu...
