Environment-friendly decorative plate and preparation method thereof

Abstract

The invention discloses an environment-friendly decorative plate. The environment-friendly decorative plate is prepared from the following raw materials in parts by weight: 15 to 20 parts of surface-modified cellulose nanocrystal, 25 to 35 parts of epoxy resin modified chitin fiber, 20 to 30 parts of waste tire rubber powder, 5 to 10 parts of kapok fiber, 5 to 10 parts of coconut fiber, 5 to 10 parts of asphalt, 2 to 5 parts of opal shale, 5 to 10 parts of nano silicon power, 2 to 5 parts of silane coupling agent KH-550 and 2 to 5 parts of nano fluorine coating wax. The invention also discloses a preparation method of the environment-friendly decorative plate. The preparation method comprises the following steps: firstly, mixing the raw materials according to weight parts and adding a mixture into a mixer, and uniformly stirring at the stirring speed of 1000 rounds / minute for 10 minutes; secondly, melting and extruding by using a double-screw extruder, wherein the temperature of a charging section is 50 DEG C, the temperature of a melting section is 120 DEG C and the temperature of a discharging section is 150 DEG C; thirdly, adding the mixture into a forming dragger to obtain a semi-finished decorative plate; fourthly, trimming, cutting and polishing the semi-finished decorative plate, and putting the polished semi-finished decorative plate into a storage after being tested tobe qualified. The environment-friendly decorative plate disclosed by the invention has the advantages of low price, excellent flame retardancy, excellent mechanical properties, radiation resistance,sound insulation and environment friendliness.
