Polyethylene/high impact polystyrene (HIPS) coated coconut shell powder particle blending foam material and preparation method thereof

The invention discloses a polyethylene/high impact polystyrene (HIPS) coated coconut shell powder particle blending foam material. The material is prepared from the following materials in part by weight: 60 to 80 parts of LLDPE (Linear low density polyethylene), 20 to 40 parts of HDPE (high-density polyethylene), 30 to 40 parts of HIPS, 10 to 15 parts of fluorite, 15 to 20 parts of water glass, 5 to 10 parts of coconut shell powder, 1 to 2 parts of tetraisopropyl di(dioctylphosphate) titanate, 5 to 8 parts of magnesium hydroxide, 4 to 6 parts of tris(dimethylbenzene) phosphate, 5 to 8 parts of tri-n-butyl citrate, 3 to 5 parts of foaming agent, 1 to 2 parts of benzoyl peroxide,0.5 to 1 part of imarcaptoacetate dioctyltin, 1 to 2 parts of zinc oxide, 1 to 2 parts of stearic acid, 2 to 3 parts of polyethylene wax, 3 to 5 parts of modified tree ash, and 1 to 2 parts of antioxidant DSTP. The polyethylene/HIPS coated coconut shell powder particle blending foam material is light in weight, flexible, high in strengt
