Problems solved by technology

[0003] Glue is widely used in people's economic life. When office supplies or daily necessities are damaged, using suitable glue to repair them can greatly reduce the cost of living; bookbinding and furniture installation sometimes require a lot of Glue, the connection between glue and people's life is getting closer; however, the traditional glue formula contains formaldehyde or aromatic compounds, these toxic substances are difficult to completely volatilize after the glue is cured and bonded, especially in inferior books and furniture. , the content of toxic ingredients is often high, which seriously endangers human health, especially children with low immunity, whose growth and development are seriously threatened by these toxic glues

Abstract

The invention relates to novel environment friendly glue and a preparation method thereof and belongs to the field of adhesive materials. The environment friendly glue includes, by weight, 30-50 parts of VAE emulsion, 20-30 parts of animal glue, 20-30 parts of plant glue, 5-10 parts of carboxymethylcellulose, 1-5 parts of talcum powder, 1-5 parts of nano SiO2, 2-4 parts of calcium carbonate, 5-15 parts of deionized water and 5-15 parts of ethanol. The environment friendly glue ensures strong adhesion force, is free of VOC emission, is free of heavy metal ions, and has low odor. The preparation method is simple in process and low in cost and has promising market application prospect.

Description

technical field [0001] The invention relates to a novel environment-friendly glue, which belongs to the field of adhesive materials. Background technique [0002] Glue is a substance that can bond two objects. Glue does not exist independently, it must be coated between two objects to play a bonding role. The chemical composition in the glue, in a water-based environment. The macromolecular body in the glue (all is round particle, and the radius of general particle is between 0.5~5 μ m. The bonding of object, realizes exactly by the pulling force between the macromolecular body in glue. In glue, Water is the carrier of the polymer body, and the water carries the polymer body and slowly immerses into the tissue of the object. When the water in the glue disappears, the polymer body in the glue relies on the mutual pulling force to hold the two objects tightly together. Tightly combined. In the use of glue, too much glue will make the polymer bodies in the glue crowded toget...
