Abstract

The invention belongs to the technical field of macromolecular materials, and provides a highly conductive antibacterial formaldehyde-free adhesive, which consists of the following raw materials in parts by weight: 12 parts of soybean protein powder, 6 parts of crosslinking agent, and 0.25 parts of modified reinforcing agent 1 part, 88 parts of dispersion medium water, wherein, the protein content in soybean protein powder is greater than or equal to 90%, the particle size is greater than 200 mesh, the modified reinforcing agent is barium titanate@silver nanoparticles, barium titanate@silver nanoparticles particle size less than 300 nm. The present invention adopts the modified core-shell structure barium titanate@silver nanoparticles to strengthen and toughen the soybean protein adhesive. The strength of the adhesive; in addition, the introduced silver ion shell has a certain inhibitory effect on bacteria and fungi, which can prolong the service life of the soybean protein adhesive, and at the same time embed the barium titanate nanoparticles in the core layer to avoid Due to the agglomeration phenomenon, the strength and toughness of the adhesive layer are reduced.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a highly conductive and antibacterial formaldehyde-free adhesive and a preparation method and application thereof. Background technique [0002] With the increase in the output of the wood-based panel industry, the amount and variety of wood adhesives are increasing. At present, the trialdehyde adhesives (urea-formaldehyde resin, phenolic resin and melamine-formaldehyde resin) in the wood industry adhesives in my country are very important. status and role. When trialdehyde adhesives are used in the production of various wood products, harmful gases such as free formaldehyde will be released during their production and use, resulting in the existence of toxic gases in the production workshop and living room, which seriously endangers people's health. At the same time, people's requirements for environmental protection have increased, and the world economy has also d...
