Abstract

The invention discloses antibacterial flame-retardant plywood and a preparation method thereof, and belongs to the technical field of plywood. The flame-retardant plywood comprises a paint layer, a surface layer, a flame-retardant layer and a shaving board layer; the shaving board layer serves as a base layer, and the flame-retardant layer, the surface layer and the paint layer are sequentially stacked on the upper surface and the lower surface of the shaving board layer; the surface layer is a wood plate; the flame-retardant layer and the flame-retardant layer are flame-retardant pc boards; and the surface layer, the flame-retardant layer and the shaving board layer are adhered by using an adhesive. Meanwhile, the invention discloses the preparation method for performing gluing by the adhesive, cold-pressing, hot-pressing and painting on the surface layer, the flame-retardant layer and the shaving board layer. The plywood provided by the invention has multiple flame-retardant effects, the surface of the plywood and the internal plate layers have antibacterial effects, and the plywood is relatively high in bonding strength and water resistance and relatively good in storage stability, avoids the harm of formaldehyde, is relatively simple in manufacturing process and equipment, and is suitable for industrial popularization and manufacturing.

Description

technical field [0001] The invention relates to the technical field of plywood, and more specifically relates to an antibacterial and flame-retardant plywood and a preparation method thereof. Background technique [0002] Plywood is a three-layer or multi-layer board-like material that is made of wood sections that are peeled into veneers or sliced ​​into thin wood, and then glued with adhesives. Usually, odd-numbered veneers are used, and adjacent layers of veneers are used. The fiber directions are glued perpendicular to each other. Plywood is usually made of basswood, ash, birch, elm, eucalyptus, pine, poplar and other materials, and is a common material for interior wall and floor decoration. [0003] There are various volatile organic compounds and harmful microorganisms in people's living environment, which directly affect people's physical and mental health. Most pathogenic bacteria in the living environment often come from the ground, furniture dirt and pets. The f...
