On-line automatic refined pasting glue and preparation method thereof

Abstract

The invention discloses on-line automatic refined pasting glue which is prepared by polymerizing the following raw materials: a monomer, a soft monomer, a functional monomer, an initiator, an emulsifier, a buffering agent, a functional aid, a viscosity modifier and distilled water. The invention further provides a preparation method of the on-line automatic refined pasting glue. The glue is green, environment-friendly, beneficial for heath, free of bad odor and free of harmful substances such as phthalic acid ester plasticizers, heavy metals and the like, and has high solid content and high toughness, so that pasted products are free of wrinkle and unlikely to be deformed; the glue is rapid to be dried at normal temperature, high in yield efficiency and good in stain reduction and cleaning capability; the residual glue on a decorative surface can be easily swept off by using a wet rag, thereby maintaining the attractiveness of the decorative surface of a base material; due to good coating property, the glue can be rapidly flattened and coated on the base material; and a final pasted product is excellent in binding strength, and glued surfaces are kept solid and durable.

Description

technical field [0001] The invention relates to an adhesive used for bonding various types of paper, especially cardboard and corrugated paper, in particular to a water-based on-line automatic fine-mounting glue that can be used for automatic on-line coating 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 prod...

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.

[0005] The polyvinyl alcohol fine mounting glue also has the problem of slow drying speed, and it also brings the problem of aldehydes harming the human body, and corn starch glue and polyvinyl alcohol are difficult to adapt to automatic on-line coating development requirements
