Abstract

The invention discloses a method for preparing an adhesive made from antibiotic bacterial residues and bean flour and belongs to the field of recycling application of antibiotic bacterial residues and a preparation of an environment-friendly adhesive. The preparation method disclosed by the invention is characterized by comprising the steps of mixing 15-45mol% of antibiotic bacterial residues and 25-55mol% of bean flour as main raw materials with a appropriate amount of 10-40mol% of additives, reacting at a constant temperature and naturally cooling. The adhesive is mainly used for bonding woods and is convenient to apply and good in adhesion property. The invention provides a harmless, resource-based, simple, feasible and economical and effective treatment method for antibiotic bacterial residues, and the production cost of the adhesive is reduced by use of antibiotic bacterial residues in the preparation of the adhesive and the field of the wood adhesives preparation is widened.

Description

technical field [0001] The invention relates to a novel water-based adhesive and a preparation method thereof, and belongs to the fields of resource utilization of antibiotic bacteria residues and preparation of environment-friendly adhesives. Background technique [0002] In recent years, my country's wood adhesives have developed greatly. Facing increasingly stringent environmental regulations and consumers' increasingly stringent quality requirements for products, adhesives have moved towards the development of bean glue, an environmentally friendly adhesive. the way. Bean gum is environmentally friendly, odorless, and does not harm human health. It is mainly used for pressing and bonding veneers. At present, researchers are mainly based on improving the water resistance and bonding strength of bean glue adhesives. For example, the publication number is CN101962529A "Soybean protein-calcium carbonate nano-adhesive and its preparation method and application" by adding cal...
