AI Technical Summary

Technical Problem

Existing three-layer solid wood boards experience a decline in moisture resistance and fire retardancy after prolonged use, and the layers are prone to cracking, leading to external erosion and affecting structural stability.

Method used

The design employs connectors and adjusters, connecting the first and second plate layers through a structure of grooves, slots, and inserts. A polyurethane layer and a perlite layer are laid on the inner side, and an epoxy resin coating is applied to the outer side to form a sealed structure that enhances connection stability and corrosion resistance.

Benefits of technology

It improves the connection stability of wood products, prevents cracking, reduces the erosion of external substances, enhances anti-corrosion and moisture-proof properties, and provides long-lasting weather resistance.
