Abstract

The invention relates to a preparation method of a slow-release type multifunctional adhesive. According to the method, through activation treatment of halloysite nanotubes and loading with a functional drug, the long-acting slow-release multifunctional adhesive is prepared, and a bamboo-wood glued material is further prepared; with use of the effect of the drug slow-released from the halloysite nanotubes, corrosion resistance, mold prevention, inhibition of formaldehyde release and multiple functions of the bamboo-wood glued material are achieved, and the long-acting effect and controllability are maintained at the same time. The method has the advantages of simple process, wide application range and high technical added value.

Description

technical field [0001] The invention relates to a preparation method of a slow-release multifunctional adhesive, more specifically to a kind of adhesive modified by halloysite nanotubes, which is used for bamboo and wood glued materials, and has the functions of anti-corrosion, mildew-proof, and formaldehyde capture. Adhesive products and preparation methods thereof. Background technique [0002] Due to the shortage of log resources in my country, bamboo-wood glued materials are important materials to meet the raw material needs of building structures, interior decoration, flooring and furniture. Like log materials, bamboo-wood glued materials need to solve the problem of anti-corrosion and anti-mildew to meet the requirements of long-term use of materials. At the same time, due to the use of adhesives in the material, in order to avoid harming human health due to the release of formaldehyde and other harmful substances, corresponding treatment needs to be done to reduce th...
