Embodiment Construction

[0007] 1. The PAL powder material (silicon dioxide content > 80%) is subjected to ultra-fine grinding treatment, the particle size is < 2 μm, and the particle surface is modified.

[0008] Add the processed flame-retardant PAL powder into the prepolymer low-viscosity resin liquid according to a certain amount of components, and fully stir to make the powder fully dispersed.

[0009] 2. The prepared flame retardant solution is diffused into the wood by pressure impregnation, and then dried in the kiln. The resin is further polycondensed to form a long-chain polymer, together with the flame retardant material. It is fixed on the surface of wood fibers to form a fire-retardant layer with good performance.

Abstract

This invention discloses a flame retardant filling of PAL material used in soakage solution processing wood materials to increase the flame retardant performance including the functions: said material enriches SiO2 and the microcosmic state is in a layer and link fiber crystal structure (an alumina octahedron is clamped between two layers of silicon tetrahedrons) and a nm hollow channel, which has fine gas-liquid obstructing performance and fine adsorption performance to smog generated by high temperature and harmful gas.

Description

technical field [0001] The invention relates to an inorganic flame retardant filler used in the flame retardant treatment liquid of wood products: PAL material rich in silicon dioxide. Background technique [0002] Wood and wood products are one of the main igniters of fire. Wooden materials are all flammable. Since humans began to use fire, they have begun the history of fighting fire. Seeking effective prevention and control of fire hazards, effective and continuous improvement of flame retardancy treatment technology for flammable wood materials is the goal pursued by human beings. At present, the most commonly used flame retardant treatment methods are the full cell method and the double vacuum impregnation method to treat wood materials, and the cost of the latter is relatively high. Contents of the invention [0003] Purpose of the present invention: [0004] 1. A new material, PAL powder rich in silica (a by-product of palygorskite ore purification), is used as a ...
