Problems solved by technology

Among them, although the production cost of starch paper tube glue is low, but the initial viscosity is low, the drying speed is slow, it is not resistant to humidity, it is easy to mold after use, and it will open when it encounters water, which greatly limits its use; white latex is water resistant. Good, but it contains formaldehyde, which has the disadvantage of polluting the working environment; in addition, the protein paper tube glue is mainly made of isolated protein (purified product of soybean flour), although the water resistance is good, but the production cost is high and the price is expensive

Abstract

The invention provides paper tube adhesive. The paper tube adhesive comprises polyvinyl alcohol, vinyl acetate, acrylamide, butyl acrylate, methyl methacrylate, peroxosulfuric acid, octyl phenol, glyoxal, water, strong base, strong acid and urea. Polyvinyl alcohol serves as protective colloid, through interaction of mixed monomers, glyoxal serves as an acetalation raw material, and the paper tube adhesive is long in storage period, high in comprehensive performance and capable of eliminating pollution of formaldehyde to the environment. The invention further provides a preparation method of the paper tube adhesive. The preparation method is simple and easy to achieve, and the prepared paper tube adhesive has the advantages of being high in viscosity, short in drying time, high in stability, free of poison emission and suitable for being widely popularized.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a paper tube adhesive and a preparation method thereof. Background technique [0002] Adhesive for paper tubes is commonly known as paper tube glue, paper tube glue, etc. It is a special adhesive for making various paper tubes, paper barrels, paper cans and related paper products. In actual production, due to the different uses of various paper products, the requirements for paper tubes are also different, and the compressive strength, hardness, toughness, water resistance, heat resistance and creep resistance of paper tube glue on paper tubes, etc. Performance plays a huge role. [0003] At present, there are mainly three types of adhesives used in the production of spinning paper tubes: starch paper tube glue, white latex, and protein paper tube glue. Among them, although the production cost of starch paper tube glue is low, the disadvantages of low initial viscosity, slow ...
