    • PURPOSE: Provided is a multifunctional thermoplastic resin which recycles waste thermoplastic resins to produce boards or timbers so that it possibly inhibits environment contamination, together with reducing production cost. CONSTITUTION: The production process of the multifunctional thermoplastic resin comprises the steps of: (i) pressing out the waste thermoplastic resin to form the resin in a chip state; (ii) drying pine sawdust which is blended with multifunctional chips and filtering to 1.2mm-2.3mm in diameter; (iii) drying pine needles which are blended with multifunctional chips and crushing to 0.5mm-1.2mm in diameter; (iv) repeatedly separating yellow earth into large particles and small particles, staying final particles in a water tank for a long time to precipitate the particles, removing water of the particles, drying the precipitated particles in a cake state and crushing to 10μm and less; (v) inserting 55wt% of the thermoplastic resins, 20wt% of the pine sawdust, 15wt% of the pine needles and 10wt% of the yellow earth into an extruding machine to form chip-typed thermoplastic resins; and (vi) supplying the chip-typed thermoplastic resins for the extruding machine to form boards as type of a die.
    • 目的:提供一种多功能热塑性树脂,其回收废热塑性树脂以生产板或木材,从而可以抑制环境污染,同时降低生产成本。 构成:多功能热塑性树脂的制造方法包括以下步骤:(i)挤出废热塑性树脂以形成芯片状态的树脂; (ii)干燥松木锯屑,与多功能芯片混合并过滤至直径1.2mm-2.3mm; (iii)将与多功能芯片混合的松针干燥并直径为0.5mm-1.2mm; (iv)将黄土重新分离成大颗粒和小颗粒,长时间保持在水箱中的最终颗粒,使颗粒沉淀,除去颗粒的水分,将沉淀的颗粒干燥成饼状,粉碎至10μm以下 ; (v)将55重量%的热塑性树脂,20重量%的松木锯屑,15重量%的松针和10重量%的黄土插入挤出机中以形成片状热塑性树脂; 和(vi)供应用于挤出机的芯片型热塑性树脂以形成作为模具类型的板。
