Abstract

The invention belongs to the technical field of adhesives, and relates to an environment-friendly composite plant adhesive, which comprises, by weight, 20-30 parts of pre-gelatinized tapioca starch, 15-25 parts of guar gum, 3-8 parts of acacia gum, 2-5 parts of seaweed powder, 5 to 10 parts of lignin, 6 to 12 parts of acrylic emulsion, 5 to 10 parts of phenolic epoxy resin, 10 to 16 parts of water-soluble urea-formaldehyde resin, 8 to 16 parts of a curing agent and 5-8 parts of an auxiliary agent; and the composite plant adhesive has high adhesive strength and good water resistance.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to an environment-friendly composite vegetable glue and a preparation method thereof. Background technique [0002] Glue is a kind of sticky agent that is used for a long time in people's daily life. The glue commonly used at present is urea-formaldehyde resin glue, and the main raw material of this glue is formaldehyde and urea, and formaldehyde often remains in the prepared glue. Formaldehyde is a kind of colorless strong irritating gas, has been identified as carcinogenic and teratogenic shape material by the World Health Organization. The release of formaldehyde is very slow. A small amount of free formaldehyde can cause respiratory diseases such as tearing eyes, skin allergies, coughing, acute and chronic bronchitis, nausea, vomiting, gastrointestinal disturbances, and in severe cases, persistent headaches, pneumonia, Pulmonary edema, loss of appetite, and even ...
