Flame retardant and antiflaming medium-density and high-density fiber panel containing flame retardant

Abstract

The invention discloses a flame retardant and an antiflaming medium-density and high-density fiber panel containing the flame retardant. The flame retardant comprises, by weight, 40-90 parts of ammonium polyphosphate, 5-50 parts of expanding agents and 5-20 parts of boride. The flame retardant is in a powder shape, is efficient expansibility flame retardant and has the advantages of being good in thermal stability, high in flame retardant efficient and low in cost. When the antiflaming medium-density and high-density fiber panel is made, the flame retardant can be directly applied to a fiber conveying pipeline and is uniformly mixed with suspended fibers in the pipeline through the action of air flow, original production procedures are seldom changed, and the problems that an existing antiflaming medium-density and high-density fiber panel is high in cost, the flame retardant addition quantity is large, energy consumption is large during drying and moisture absorption of the fiber panel is high are solved.

Description

Technical field [0001] The invention relates to the technical field of wood processing, in particular to a flame retardant, and also to a flame retardant medium and high density fiberboard containing the flame retardant. Background technique [0002] Fiberboard is a board or profile made of wood or other plant fibers by adding adhesives and waterproofing agents through drying, paving, hot pressing, sanding and other processes. With its good physical and mechanical properties and processing performance, fiberboard is widely used in building decoration, furniture production, floor production, ship and vehicle interior decoration. The composition of fiberboard is similar to that of other wood materials. It has a higher combustion heat value, a lower ignition temperature and a fast flame propagation speed, so the fire prevention ability is very low. Medium and high-density fiberboard is a kind of medium and high-grade wood board made of wood fiber as raw material by applying urea-fo...

AI Technical Summary

Problems solved by technology

This type of method has the following disadvantages: the fiberboard loses its good processing performance and use performance; the bonding and finishing performance of the facing material is poor, and the service life is short

A large amount of flame retardant is applied, on the one hand, it leads to high cost of flame retardant, on the other hand, it will seriously affect the physical and mechanical properties of the product, and it is necessary to increase the amount of sizing to make up for it, so that the amount of sizing in this method can reach as high as 220-240kg / m 3

Therefore, this method still has the problem that the amount of flame retardant and sizing agent is relatively large, and the cost of flame retardant is high.
