Formaldehyde-free environment-friendly glue

Abstract

The invention discloses a formaldehyde-free environment-friendly glue. The glue is prepared from, by weight, 50-90 parts of vinyl acetate emulsion, 25-40 parts of salicylic acid, 10-15 parts of acaciagum, 20-40 parts of protein adhesive, 8-20 parts of silicon dioxide, 5-20 parts of hide glue, 6-10 parts of bone glue, 2-50 parts of starch, 1-3 parts of carbonic acid, 1-3 parts of polyvinyl alcohol, 0.5-1 part of polyacrylamide, 0.5-1.5 parts of hydrogen peroxide, 0.3-0.5 part of ethylene glycol, 1-4 parts of ethyl alcohol, 0.05-0.1 part of sodium stearate, 2-8 parts of sucrose, 5-9 parts of dispersing agent and 1-5 parts of water.

Description

technical field [0001] The invention belongs to the field of glue, and in particular relates to an formaldehyde-free environment-friendly glue. Background technique [0002] Glue is an intermediate that connects two materials. It mostly appears as water agent and has a wide variety, mainly based on the classification method of adhesive material, physical form, hardening method and adherend material. At present, glue generally has the characteristics of weak cohesive force, and contains toxic and harmful substances, such as formaldehyde, which will cause harm to the human body during use. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides an formaldehyde-free environmental glue. [0004] The present invention adopts the following technical scheme: a formaldehyde-free environmental protection glue, which is composed of the following raw materials in parts by weight: 50-90 parts of vinyl acetate emulsion, 25-40 p...
