Abstract

The invention discloses a preparation method of an antibacterial electromagnetic shielding type plywood, and belongs to the technical field of plates. According to the method, the polyaniline monomersare used as raw materials, the arrangement and conformation of the polyaniline main chains are changed; the conductivity of the polyaniline reaches the maximum value; the electromagnetic shielding performance of the modified polyaniline solution is greatly improved; the wood core board is placed in the modified polyaniline solution for dipping, so that the modified polyaniline solution with the electromagnetic shielding effect is attached to the surface of the wood core plate; the honeysuckle contains rich achyranthes bidentata, inositol, tannic acid and other effective components and can beused for inhibiting various bacteria; silica gel is amorphous silicon dioxide, the chlorhexidine acetate solution can be adsorbed by silica gel, due to the use of the chlorhexidine acetate solution, the antibacterial performance of the plywood prepared by the method can be improved; 3-Glycidoxypropylthrimethoxysilane is used as a coupling agent, mixed and stirred with silica gel adsorbed with chlorhexidine acetate, so that the antibacterial silica gel adhesive is fully fused into an adhesive state. The antibacterial electromagnetic shielding type plywood has a wide application prospect.

Description

technical field [0001] The invention discloses a preparation method of antibacterial electromagnetic shielding type plywood, which belongs to the technical field of boards. Background technique [0002] Plywood is one of the commonly used materials for furniture and is a kind of wood-based panel. 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. One of the commonly used materials for furniture is a wood-based panel. A group of veneers are usually assembled and glued together according to the direction of the wood grain of adjacent layers perpendicular to each other. Usually, the surface board and inner layer board are symmetrically arranged on both sides of the center layer or core. The slab made of the vene...
