Problems solved by technology

Due to the problems that the added flame retardants are easily decomposed and lost with rainwater in the process of outdoor use, the flame retardancy of plastic-wood composite materials used outdoors decreases rapidly until they disappear, and with the loss of the added flame retardants , resulting in uneven surface of plastic wood and a sharp decline in flame retardancy

Abstract

The invention relates to a body flame retardant plastic wood composite material and a preparation method thereof. the composite material is prepared from a body flame retardant fabric and a core material, wherein the body flame retardant fabric is mainly prepared from vinyl phosphate, cis-3-ethyl bromoacrylate, hexachlorocyclopentadiene, acrylic acid, melamine and pentabromophenol as major raw materials; the body flame retardant core material can be mainly prepared from brominated epoxy resin, thermoplastic phenolic resin, wood flour, lubricating agents, aluminum hydroxide and compatilizers asraw materials. The plastic wood composite material has durable flame retardant performance.

Description

technical field [0001] The invention belongs to the technical field of flame-retardant materials, and in particular relates to a body flame-retardant plastic-wood composite material and a preparation method thereof. Background technique [0002] The weather resistance of acrylic resin is very good, it is the first choice of outdoor weather resistance resin, it is often used in the top coat of the car body, and the co-extruded plastic-wood composite material, the fabric should be exposed to the outdoors for a long time, and as a co-extruded plastic-wood material The flame retardant performance of the surface layer directly affects the flame retardant performance of the plastic wood material. If the flame retardant performance is excellent, then the external heat source cannot touch the core material at all, so the flame retardant performance of the co-extruded plastic wood composite material must be very outstanding. . [0003] Currently commonly used fabric materials such a...
