Embodiment 1

[0015] Example 1: First mix potassium permanganate and inorganic acid in a ratio of 1:3 to form a composite oxidant. Then take by weighing 25KG of cornstarch, 50KG of water, 3KG of urea peroxide, 0.005KG of nickel sulfate, 0.12KG of boric acid, 0.3KG of composite oxidant, 0.016KG of nanometer sepiolite powder, and 0.2KG of polyacrylamide. The preparation method is to prepare to obtain the composite adhesive for corrugated box.

Embodiment 2

[0016] Example 2: First mix potassium permanganate and inorganic acid in a ratio of 1:5 to form a composite oxidant. Then weigh 30KG of corn starch, 55KG of water, 13KG of urea peroxide, 0.05KG of nickel sulfate, 0.16KG of boric acid, 0.45KG of composite oxidant, 0.06KG of nano sepiolite powder, and 1KG of polyacrylamide, and prepare modified starch according to the routine The preparation method is to obtain the complex adhesive for corrugated cartons.

Embodiment 3

[0017] Example 3: First mix potassium permanganate and inorganic acid in a ratio of 1:5 to form a composite oxidant. Then take by weighing 25KG of cornstarch, 50KG of water, 0.15KG of boric acid, 0.35KG of composite oxidant, 7KG of urea peroxide, 0.035KG of nickel sulfate, and 0.65KG of polyacrylamide, and prepare according to the conventional modified starch preparation method, to obtain Compounding adhesives for corrugated boxes.

Abstract

The invention discloses a multi-effect adhesive for corrugated cartons. The multi-effect adhesive is characterized by being made from raw materials in parts by weight as follows: 25-30 parts of corn starch, 50-55 parts of water, 3-13 parts of urea peroxide, 0.005-0.05 part of nickel sulfate, 0.12-0.16 part of boric acid, 0.3-0.45 part of a compound oxidizing agent, 0.016-0.06 part of nanometer sepiolite powder and 0.2-1 part of polyacrylamide. The multi-effect adhesive has the advantages of quick drying, good combination property and low production cost. The urea peroxide is taken as a main oxidizing agent and matched with the nickel sulfate, and meanwhile, the polyacrylamide is selected as a modifier, so that properties such as gel resistance, moisture absorption, flexibility, viscosity and the like of oxidized starch are improved effectively, and multiple purposes are achieved once.

Description

technical field [0001] The invention relates to a starch adhesive, in particular to a modified starch adhesive specially used for bonding 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 Intel...
