Problems solved by technology

At present, most starch adhesives are used, but when the starch adhesive meets water, the bonding strength will decrease, and the moisture will penetrate the face paper, corrugated paper and inner paper, which will further cause the corrugated box to absorb water and become soft, and the edges will be degummed and warped. Deformation and other phenomena occur, resulting in deterioration and damage of internal products. Therefore, there is an urgent need to develop a corrugated paper adhesive. It has high bonding strength and has a certain degree of water resistance.

Abstract

The invention discloses a corrugated paper adhesive and a preparation method thereof. The corrugated paper adhesive is prepared from the following raw materials in parts by weight: 50-100 parts of water-based tackifying resin, 10-15 parts of phytic acid, 5-8 parts of paraffin, 10-15 parts of sepiolite powder, 10-18 parts of polyurethane, 20-25 parts of oxidized polyethylene, 4-6 parts of modifiedbutyl acrylate, 3-5 parts of rosin, 5-10 parts of epoxy soybean oil, 2-3 parts of wood fibers, 1-2 parts of sulfur, 10-20 parts of a modifier, 100-150 parts of water and 6-15 parts of an antioxidant.According to the corrugated paper adhesive provided by the invention, reasonable raw materials and proportion ratio are selected, various raw materials act synergistically and supplement each other, and a cross-linked long-chain polymer can be formed in the production process; the oxidation speed of the adhesive is fast after the adhesive is in contact with the air, and the cross-linked long-chainpolymer distorts and deforms to form an irregular form due to oxygen, so that the adhesive property is greatly enhanced; moreover, when the adhesive provided by the invention encounters water, the adhesive strength does not decrease, and moisture cannot permeate the adhesive body, so that the structure stability of a corrugated paper box is ensured.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a corrugated paper adhesive and a preparation method thereof. Background technique [0002] Corrugated cardboard is die-cut, creasing, nailed or glued to make corrugated boxes. Corrugated carton is the most widely used packaging product, and its consumption has always been the first among all kinds of packaging products. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transportation packaging containers due to their superior performance and good processing performance, and have become the main force of transportation packaging. In addition to protecting the goods and facilitating storage and transportation, it also plays the role of beautifying and promoting the goods. Corrugated boxes are green and environmentally friendly products, which are conducive to environmental protection and are conducive to loading, unloading ...
