Title:
WOOD-PLASTIC COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2021/135986
Kind Code:
A1
Abstract:
A wood-plastic composite material comprising a flame retardant. The flame retardant adopts a three-layer structure. The flame retardant comprises an outer shell, a middle layer and an inner core. The component of the outer shell is aluminum hydroxide, the component of the middle layer is hydrated zinc borate, and the component of the inner core is magnesium hydroxide; the particle diameter of the flame retardant is: D50 < 60 nm, D90 < 100 nm; the inner core is connected to the middle layer by means of an adhesive, and the middle layer is connected to the outer shell by means of an adhesive. Flame retardation is performed in a gradient progressive manner. Aluminum hydroxide exerts flame retardant effect at 200℃. When the temperature is still increased, hydrated zinc borate at 300℃ is thermally decomposed, and crystal water is released, thereby achieving flame retardation. When the temperature is further increased, magnesium hydroxide can achieve flame retardation at 340-490℃, such that the flame retardant effect is improved by performing flame retardation in a continuous gradient progressive manner.
