Abstract

The invention relates to the technical field of wood processing and particularly relates to a wood flame retardant and an application thereof. The wood flame retardant includes, by weight, 25-35 parts of melamine, 30-40 parts of boron acid, 10-15 parts of zinc borate, 10-20 parts of zinc sulfate, and 10-15 parts of sodium tripolyphosphate. The raw materials of the wood flame retardant have synergistic flame retarding effects, so that the flame retardant is good in flame retarding effect, is low-toxicity, has good smoke inhibition property and is environment-friendly, and is also low in cost. Flame retarding plywood produced from the flame retardant is significantly improved in flame retarding performance, which can reach C-level fireproofing grade in national standard. Bonding strength and maximum fracture load of the plywood are approximated to plywood produced without the flame retardant.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a wood flame retardant and its application. Background technique [0002] Due to the excessive use of wood by humans, the number of various valuable and large-diameter woods is getting less and less, so humans realize the comprehensive utilization of wood in various ways. The birth of wood-based panels marks the beginning of the modern era of wood processing, which makes the process develop from simply changing the shape of wood to improving the properties of wood. People plant artificial forests and make various wood-based panels from the wood cut from the artificial forests, so as to meet people's needs for precious wood and large-diameter wood. Making wood into wood-based panels maintains the characteristics of lightness and good mechanical properties of logs, and at the same time has large format, good structure, and convenient construction; low expansion and contrac...
