Abstract

The invention relates to the technical field of flame-retardant shaving board preparation, in particular to a flame-retardant shaving board preparation method based on double-layer coated ammonium polyphosphate microcapsule modification, which comprises the following steps: S1, aluminum hydroxide coated ammonium polyphosphate modification: ammonium polyphosphate is added into absolute ethyl alcohol and fully stirred to form a suspension, an aluminum chloride solution is added and fully stirred, and filtration is performed to obtain an aluminum hydroxide coated ammonium polyphosphate suspension; washing and drying to obtain aluminum hydroxide coated ammonium polyphosphate; s2, dopamine secondary coating modification: dopamine is added into deionized water, and a dopamine solution is prepared; then adding the aluminum hydroxide coated ammonium polyphosphate prepared in the step S1; s3, preparing a metal ion salt solution; s4, wood shaving modification; and S5, wood shaving sizing and paving. The preparation method is simple, easy to implement and capable of quickly adapting to the production process and technology of existing shaving boards, secondary processing equipment is avoided, cost is saved, and the prepared shaving boards have excellent mechanical property and flame retardant property.

Description

Technical field [0001] The present invention relates to the preparation of flame retardant particle plates, and is a method for preparing a flame-retardant particleboard based on double coated polyphosphate microcapsule modification. Background technique [0002] Particleboard is a kind of man-made panel, mainly based on wood or non-wood plant fiber feedstock, which is thermal and pressure to heat and pressure, and has a large, structure. Uniform, good processing performance, extensive source, low cost, etc., has been widely used in furniture, floor substrates, cabinets, custom wardrobes, building wall panels. However, since the particleboard is mainly composed of wood material, poor fire resistance is poor, it is easy to burn, and the fire is prone to fire, which limits the application range of particleboard. Therefore, the particleboard is flame retardant and imparted to its flame retardant properties. [0003] The ammonium polyphosphate (APP) is widely used, the price is low, ...
