Abstract

The invention discloses a wood-plastic reinforced imitation solid wood environment-friendly plate and a preparation method thereof. The wood-plastic reinforced imitation solid wood environment-friendly plate comprises the following raw materials in parts by weight: 100-120 parts of modified polyallylbenzene, 30-50 parts of toughening fibers, 60-80 parts of wood flour and 10-15 parts of calcium carbonate. Through the modified polyallylbenzene, when a layer of protective film is formed on the surface of the imitated solid wood environment-friendly plate during combustion, diffusion of combustible gas and oxygen can be isolated, heat radiation of flame to a solid phase can be prevented, and combustion is inhibited; meanwhile, flame-retardant components are located on a side chain of the modified polyallylbenzene, such a distribution mode is different from a mode of directly adding a flame retardant into a traditional flame-retardant material, organic flame-retardant components cannot be separated out, the lasting flame-retardant effect is ensured, meanwhile, the environment-friendly requirement is met; the mechanical performance of the imitation solid wood environment-friendly plate is improved through toughening fibers, and the service life of the plate is prolonged.

Description

technical field [0001] The invention relates to the field, in particular to a wood-plastic reinforced imitation solid wood environment-friendly plate and a preparation method thereof. Background technique [0002] Wood-plastic composite board is a kind of wood (wood cellulose, plant cellulose) as the basic material, thermoplastic polymer material (plastic) and processing aids, etc., which are mixed evenly and then heated and extruded by mold equipment. The high-tech green environmental protection new decorative material has both the performance and characteristics of wood and plastic, and is a new composite material that can replace wood and plastic. Wood-plastic composites have developed rapidly due to their excellent performance in just a few decades. In recent years, some waste fibers such as straw, straw, corn stalks and other waste fibers have been used to prepare wood-plastic composites. [0003] The existing wood-plastic panels have the disadvantages of brittle textu...
