Problems solved by technology

[0004] Corn starch glue mostly adds a large amount of alkaline substances in the formula. The presence of such alkaline substances can easily change the ink and affect the performance of other subsequent processing, especially for laminating products, resulting in a decrease in the strength of the laminating film.
The solid content of corn starch glue is low, and a large amount of water needs to be volatilized when used, so the drying speed is slow, especially in winter, manufacturers often affect the production speed because it is difficult to dry
In addition, due to the high salt content in the glue, it is easy to absorb moisture, which makes it difficult to guarantee the stability of the product.
The polyvinyl alcohol-based fine mounting glue also has the problem of slow drying speed, and it also brings the problem of aldehydes harming the human body

Abstract

The invention relates to fine pasting glue, which is polymerized by the following raw materials of a hard monomer, a soft monomer, a functional monomer, an initiating agent, an emulsifying agent, a buffering agent, a functional auxiliary agent, a viscosity regulator and deionized water. The fine pasting glue and a preparing process thereof also provides a process for preparing the fine pasting glue. The fine pasting glue and the preparing process thereof have the advantages in that the fine pasting glue is of green environmental protection and good for health and contains no bad odor and harmful substances such as phthalic acid esters plasticizer, heavy metals and the like; as the fine pasting glue has high solid content and high tenacity, products pasted are wrinkle-free and uneasy to deform under the normal temperature, and the fine pasting glue is rapid in drying, high in yielding efficiency, and good in scouring and cleaning. The adhesive residue on the facing can be easily cleaned by a wet cloth so that an attractive appearance of a substrate facing is kept; the coating is good in performance so that the glue can achieve rapid leveling and coating on the substrate; and finally the pasted products have a good bonding strength and can keep the glue-bonded surface solid and durable.

Description

technical field [0001] The invention is applied to an adhesive used for bonding between various papers, especially between cardboard and corrugated paper, and particularly relates to a water-based fine mounting glue and a preparation method thereof. Background technique [0002] Fine mounting glue refers to the glue used for bonding between various types of paper, especially the bonding between cardboard and corrugated paper. Fast drying, strong adhesion, no influence on the ink, no discoloration, etc. are required. It can be divided into machine type and manual type. [0003] Due to historical reasons, traditional fine mounting glues are mostly corn starch glues and polyvinyl alcohols. [0004] Corn starch glue mostly adds a large amount of alkaline substances in the formula. The presence of such alkaline substances can easily change the ink and affect the performance of other subsequent processing, especially for laminating products, resulting in a decrease in the streng...
