AI Technical Summary

Technical Problem

Existing engineered wood flooring is flammable and poses a fire safety hazard, and the overall flame-retardant treatment results in waste.

Method used

It adopts a multi-layer structure design, including a solid wood base layer, a multi-layer board layer, a solid wood top layer, and a flame-retardant board layer. A flame-retardant microparticle layer and a flame-retardant paint layer are set on the top. Aluminum oxide powder is used as a flame retardant, combined with flame-retardant adhesive and environmentally friendly flame-retardant paint for protection.

Benefits of technology

It effectively prevents flames from penetrating the floor itself, avoids the need for overall fireproofing treatment, improves the floor's flame-retardant performance, and does not affect its environmental performance.

Abstract

The utility model relates to a flame-retardant multi-layer solid wood floor which comprises a wood floor body, and the wood floor body comprises a solid wood bottom plate layer, a multi-layer plate layer, a solid wood top plate layer and a flame-retardant plate layer which are located on the bottom layer. The first side face of the floor body is provided with a main tenon, and the second side face is provided with a main mortise. The main tenon is matched with the main mortise; an auxiliary tenon groove is formed over the main tenon, and an auxiliary tenon is arranged over the main tenon groove. The auxiliary mortise is matched with the auxiliary tenon; a flame-retardant particle layer is arranged at the top of the flame-retardant plate layer A flame-retardant surface paint layer is arranged on the outer surface of the flame-retardant particle layer; the two ends of the flame-retardant surface paint layer extend to the side face of the auxiliary mortise and the position above the auxiliary tenon correspondingly to wrap the top. The multi-layer solid wood floor has the advantages that the top of the multi-layer solid wood floor can be protected by covering the flame-retardant paint layer, the flame-retardant particle layer and the flame-retardant plate layer on the top of the multi-layer solid wood floor, flames are prevented from invading the floor body, and overall fire prevention is not needed.
