Problems solved by technology

However, the flame retardant used in this patent is a liquid flame retardant, which is inconvenient to store and transport, and the liquid flame retardant is bound to greatly increase the moisture content of the fiber before drying, so that the original widely used primary drying system cannot meet the requirements of the fiber. Due to the drying requirements, secondary drying has to be adopted, which is equivalent to adding an additional drying system than the original one, so the amount of equipment transformation brought about is large, and the cost of technical transformation is high; moreo

Abstract

The invention discloses a high-grade environment-friendly flame-retardant fiberboard and a manufacturing method thereof. Wood chips are used as raw materials and hot-ground to obtain fibers, auxiliary raw materials are added to the fibers, and the high-grade environment-friendly flame-retardant fiberboard is manufactured. Each cubic meter of the high-grade environment-friendly flame-retardant fiberboard is composed of, by weight, 580-630kg of fibers, 7-9kg of paraffin, 200-230kg of adhesive (the solid content ranges from 40% to 50%), 0.2-0.3kg of curing agent, 1.0-2.0kg of coloring agent, 38-50kg of fire retardant and appropriate water. The manufacturing method of the high-grade environment-friendly flame-retardant fiberboard comprises the working procedures of hot-grinding, mixing, drying, shaping, hot-pressing, edge cutting and sanding. Production processes are simple, technical parameters are accurate, process reliability is strong, production efficiency is high, and the high-grade environment-friendly flame-retardant fiberboard produced in the manufacturing method is good in flame retardant property, low in formaldehyde emission and excellent in physical and mechanical performance.

Description

technical field [0001] The invention belongs to the technical field of wood-based panels, and relates to a high-grade environmentally friendly flame-retardant fiberboard with strong process reliability, product environmental protection and good flame-retardant performance and a manufacturing method thereof. Background technique [0002] With the continuous development of the national economy, wood-based panels, as an important engineering material, are more and more widely used in building decoration, furniture production, floor production, ship and vehicle interior decoration and other fields, playing an important role in the construction of the national economy. However, like other wood-based materials, wood-based panels are a high fire hazard due to their high flammability value, low ignition temperature and very fast flame propagation velocity. In my country, the number of casualties and property losses caused by fires caused by wood materials is increasing year by year....
