Problems solved by technology

However, since the polystyrene imitation wood material has been exposed to the outdoors for a long time, and is subjected to different external conditions such as wind, sun, rain, etc., the added flame retardant will decompose and will be lost with the rain, resulting in the polystyrene imitation wood material being damaged. The surface is uneven and the flame retardant performance drops sharply

Abstract

The invention relates to a body flame-retardant polystyrene foaming wood-imitation material and a preparation method thereof. The material is prepared from the following raw materials in percentage bymass: 30 to 50 percent of flame retardant copolymer polystyrene, 20 to 45 percent of small molecular weight polytetrafluoroethylene, 10 to 25 percent of inorganic flame retardant fillers and 1 to 3 percent of foaming agents, wherein the flame retardant copolymer polystyrene is prepared from diethyl vinylphosphonate, 4-bromine-beta,beta-difluorostyrene, tribromo-ethylene, 3-bromostyrene and triphenylvinylsilane as raw material monomers through copolymerization. The polystyrene foaming material provided by the invention has good mechanical performance and durable flame-retardant performance.

Description

technical field [0001] The invention belongs to the technical field of imitation wood materials, in particular to a body flame-retardant polystyrene foam imitation wood material and a preparation method thereof. Background technique [0002] Imitation wood is a kind of technology. Using this technology, various products that look like solid wood can be produced, and it can also be used as a construction plan for on-site construction. For example, if the exterior wall of a house needs to be decorated with imitation wood, on-site construction must be carried out. Wood-like materials are designed to replace real wood and save forest resources. From the appearance of the products made by imitation wood technology, the visual effects of imitation wood and real wood products are comparable, and the fake wood can be confused with the real one, and it is even difficult to distinguish them. It will not be corroded and faded by wind and sun for a long time, let alone insects, which i...
