▎ 摘　　要

NOVELTY - Production of waste plastic composite material modified with compatibilizer involves (i) dissolving compatibilizer containing maleic anhydride (MAH) and dicumyl peroxide (DCP) in a solvent and mixing the mixture with waste plastic, (ii) precipitating the mixture with an excess of acetone and separating the acetone from the mixture by evaporation, (iii) drying the separated mixture and (iv) polymerizing the dried mixture. USE - Production of waste plastic composite material used for forming intermediate product (all claimed) used for construction and civil engineering, construction wall, pallet, hydroponic cultivation box and packaging material. ADVANTAGE - The method provides waste plastic composite material having excellent mechanical strength, excellent physical properties and excellent quality.
