Abstract

The invention discloses a method for preparing a sheet material adhesive and relates to the field of sheet material production. The method for preparing the sheet material adhesive comprises the steps: (A) adding a protein-containing raw material into water, and stirring uniformly; (B) carrying out ultrasonic treatment on the solution obtained in the step (A); (C) adding sodium dodecylbenzene sulfonate into the solution obtained in the step (B), and stirring; (D) adding boric acid into the solution obtained in the step (C), and stirring; (E) adding hexa-acetamide, a reinforcing agent and an anticorrosive agent into the solution obtained in the step (D), and stirring uniformly, thereby obtaining the sheet material adhesive. According to the method, the sheet material adhesive prepared by the method is used for solving the problems that the existing synthetic resin adhesives release formaldehyde, pollute environment and are harmful to human. The sheet material adhesive is low in cost, high in bonding strength and good in water resistance and corrosion resistance and can cure at normal temperature, and particularly the low-temperature resistance is better than that of other adhesives.

Description

Technical field [0001] The invention relates to the field of plate production, in particular to a method for manufacturing a plate adhesive. Background technique [0002] At present, 90% of the adhesives used in the board production process are "trialdehyde glue (trialdehyde refers to phenolic, urea-formaldehyde, melamine formaldehyde, the same below)", but "trialdehyde glue" will release formaldehyde during use, which will seriously harm people Healthy body. [0003] Therefore, the research and use of efficient, healthy, and low-cost adhesives is not only a requirement of consumers for enterprises, but also a requirement of increasingly stringent environmental regulations. Summary of the invention [0004] The present invention provides a method for manufacturing a sheet adhesive. The sheet adhesive produced by the sheet adhesive can solve the problem that the existing synthetic resin adhesive releases formaldehyde, pollutes the environment and is harmful to the human body. [0005...
