Abstract

The invention belongs to the technical field of building decorative materials, in particular to a foamed polystyrene composite material with excellent tensile creep resistance and bromine-free flame retardancy, and further discloses a preparation method thereof. The foamed polystyrene composite material mainly uses general-purpose polystyrene, phenolic resin, polypropylene mesh fiber, rock wool fiber, polyetherimide and polytetrafluoroethylene fiber as raw materials, and is obtained by adding compatibilizer, lubricant, coupling agent, foaming agent and ultraviolet light absorber as assistants for extrusion granulation and molding. Under the coordination of the raw material components, the tensile creep resistance and flame retardant performance of the foamed polystyrene composite material is greatly improved, the composite material does not contain toxic bromine flame retardant, can be used in the field requiring high tensile creep resistance and flame retardant performance of the foamed polystyrene composite material, and the application field of the foamed polystyrene composite material is greatly expanded.

Description

technical field [0001] The invention belongs to the technical field of building decoration materials, in particular to a foamed polystyrene composite material with excellent tensile creep resistance and bromine-free flame retardancy, and further discloses a preparation method thereof. Background technique [0002] All-plastic composite material is a kind of composite material made entirely of plastic, which does not use any wood components, and is prepared by micro-foaming, injection or extrusion molding and other processing techniques to obtain products that are similar in appearance to wood and have a density equivalent to that of wood. Expanded polystyrene composite material is one of the research directions. [0003] Compared with the first generation of wood-plastic composite materials, expanded polystyrene composite products have light weight, excellent water resistance, durability and decorative properties, and are widely used in the market. However, compared with th...
