Abstract

The invention discloses a compounding method of a halogen-free environmentally friendly wood fire retardant. The method comprises the following steps: 1, weighing 15-40wt% of phosphoric acid, 10-30wt% of an amino compound, 5-20wt% of boric acid, 5-25wt% of water-soluble ammonium polyphosphate, 5-15wt% of silicide, 3-8wt% of sodium molybdate, 0.5-3wt% of triethanolamine, 0.5-2wt% of dodecyl dimethyl benzyl ammonium chloride, and 0.1-1wt% of pentaerythritol; 2, mixing phosphoric acid with the amino compound, and reacting at 70-90DEG C for 2-4h; and 3, adding other components, mixing, and adding water to prepare a solution. The preparation method has the advantages of simplicity, cheap and easily available raw materials, low cost and no pollution, and the above obtained product has the advantages of good flame retardation and smoke inhibition effects on wood, low hygroscopicity, strong penetration, dimensional stability, good bleaching resistance, convenient application, good corrosion, mildew and moth resistance, and easy realization of industrial production.

Description

technical field [0001] The invention relates to the technical field of wood flame retardants, in particular to a method for compounding a halogen-free and environment-friendly wood flame retardant. Background technique [0002] As an important material for industrial engineering, wood has been widely used in construction, interior decoration, furniture and other fields, and is favored by people. However, wood is a flammable material that can easily cause a fire. Therefore, the protective treatment of fire retardants on wood is an indispensable method to improve performance, broaden the application range and reduce fire hazards. Some of the existing flame retardants have no obvious flame retardant effect on wood; although some can play a good flame retardant effect, they will produce a large amount of toxic gases when burned, which will affect human health. Contents of the invention [0003] In view of the above deficiencies in the prior art, the present invention provide...
