Problems solved by technology

[0002] At present, the adhesives used by domestic paper product manufacturers to produce paper tubes, cartons, cartons, honeycomb cardboard and other paper products are mostly white latex and starch glue. White latex uses vinyl acetate monomer as the main raw material, and the polymerization is initiated by an initiator. It can be applied to the bonding production of paper products and basically meets the technical requirements. However, as the price of vinyl acetate monomer raw materials continues to rise, the price of white latex also increases day by day, resulting in higher costs and low profits in the paper product industry.
The other is starch glue. Starch glue is made by oxidizing starch with oxidant, gelatinizing it with caustic soda, and then crosslinking it with a crosslinking agent. Because its product contains a certain amount of caustic soda, the pH value is relatively high. It makes the dried paper products easy to absorb moisture from the air, so that the paper products absorb moisture and become soft, so that their strength cannot meet the requirements
Moreover, the general starch glue solid content is not high, which contains a large amount of water, resulting in slow drying of the produced product. After the production steps are completed, it needs sufficient time to dry it, which not only affects the production efficiency, but also takes up too much production. site
