Problems solved by technology

However, traditional sealant products are generally made of phenolic resin and related additives. However, phenolic resin is a thermosetting resin. After the sealant is sprayed and cured on the surface of the board, it is prone to poor film-forming properties. The film is uneven, easy to crack, etc. At the same time, its drying time is also long, and the use efficiency is not high
In addition, many plate sealant products still have the problem of low stability, which limits the long-term use of the product

Description

technical field [0001] The invention relates to the technical field of air purification, and more specifically, the invention provides an environment-friendly board sealant and a preparation method thereof. Background technique [0002] With the rapid development of social economy and the continuous improvement of living standards, people have higher and higher requirements for living environment, home decoration, furniture renewal, etc. are becoming more and more frequent, and the accompanying environmental pollution is becoming more and more serious. Plywood, particleboard, medium density fiberboard and other wooden materials and furniture and building materials made of them often contain a large amount of formaldehyde-based adhesives. In recent years, formaldehyde has been recognized by the World Health Organization as a carcinogenic and teratogenic agent due to various diseases caused by formaldehyde. substance. Due to the slow release of formaldehyde, it poses a seriou...
