Abstract

The invention relates to the technical field of plywood, and discloses a fireproof formaldehyde-free plywood and a manufacturing method thereof.The fireproof formaldehyde-free plywood comprises three veneers, the three veneers are connected through glue in a hot-pressing mode, the three veneers are sequentially a face plate, a middle plate and a bottom plate from top to bottom, and the middle plate comprises the following raw materials: 20-40 parts of straw residues, 20-30 parts of bamboo boards, 50-60 parts of rock wool, 10-20 parts of an aluminum hydroxide flame retardant, 1-3 parts of an antibacterial agent and 100-140 parts of glue. According to the fireproof formaldehyde-free plywood and the manufacturing method thereof, the bottom plate and the middle plate have good fireproof performance, glue and raw materials used in production are reasonable in proportion, formaldehyde harmful substances are not contained, the gluing performance and the stability performance are good, and the fireproof formaldehyde-free plywood has good water resistance, so that the environment-friendly effect is achieved.

Description

technical field [0001] The invention relates to the technical field of plywood, in particular to a fireproof formaldehyde-free plywood and a manufacturing method thereof. 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. [0003] After retrieval, the publication number is CN 102699963 A which discloses a kind of anti-corrosion plywood and its production method. It is made after drying for a period of time, and the glue-coated anti-corrosion veneer is made by coating the upper and lower surfaces of the anti-corrosion veneer with adhesive. The anti-corrosion plywood is obtained by stacki...
