Abstract

The invention relates to the technical field of plywood, and discloses a method for making fire-resistant formaldehyde-free plywood, which comprises three plates, which are connected by glue hot-pressing, and the three plates are, from top to bottom, a panel, a middle plate and a The bottom plate, the middle plate includes the following components of raw materials, 20-40 parts of straw slag, 20-30 parts of bamboo board, 50-60 parts of rock wool, 10-20 parts of aluminum hydroxide flame retardant, 1-3 parts of antibacterial agent and Glue 100‑140 parts. The manufacturing method of the fire-resistant formaldehyde-free plywood, the bottom plate and the middle-layer board, all have good fire resistance, the glue used in the production has a reasonable ratio of raw materials, does not contain formaldehyde harmful substances, has good gluing performance and stability, and has good performance. Water resistance, so as to play a role in environmental protection.

Description

technical field [0001] The invention relates to the technical field of xx, in particular to a manufacturing method of a fireproof formaldehyde-free plywood. Background technique [0002] Plywood is one of the commonly used materials for furniture and is a kind of artificial board. Plywood is a three-layer or multi-layer board-like material that is made of wood segments or sliced ​​into thin wood, and then glued with adhesives. Usually, odd-numbered layers are used, and the fiber direction of adjacent layers of plates is adjusted. They are glued vertically to each other. [0003] After retrieval, publication number CN 102699963 A discloses an anti-corrosion plywood and a production method thereof. The anti-corrosion plywood is obtained by alternately stacking and cold-pressing anti-corrosion plates and glue-coated anti-corrosion plates; It is prepared by drying, and the glue-coated anti-corrosion plate is prepared by coating the upper and lower surfaces of the anti-corrosio...
