Abstract

The invention discloses a sheet material adhesive and relates to the field of sheet material production. The sheet material adhesive contains the following raw materials in parts by weight: 80-100 parts of protein-containing raw material, 0.5-2.5 parts of sodium dodecylbenzene sulfonate, 5-8 parts of boric acid, 10-30 parts of hexa-acetamide, 10-30 parts of reinforcing agent and 10-30 parts of anticorrosive agent. The sheet material adhesive disclosed by the invention 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 board production, in particular to a board 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 seriously endangers people. In good health. [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 protection regulations for enterprises. Contents of the invention [0004] The invention provides a plate adhesive, which can solve the problems that the existing synthetic resin adhesive can release formaldehyde, pollute the environment and be harmful to human body. [0005] In order to solve the above problems, the technical solution a...
