    • The objective of the present invention is to provide an ethylene-based composite resin composite particle having a small-sized, approximately spherical form, comprising functional filler homogeneously dispersed therein, and being compatible with other resin pellets or components. To attain the above objective, the present invention provides an environmentally friendly method for producing an ethylene-based resin composite particle, comprising: (a) dissolving ethylene-based polymer in organic solvent separable from aqueous phase and dispersing hydrophobic filler in environment-friendly organic solvent to form solution of ethylene-based polymer in the organic solvent; (b) emulsifying the solution obtained in step (a) in non-ionic surfactant-containing aqueous solution; (c) heating the emulsion obtained in step (b) to remove the organic solvent; and (d) recovering a precipitate the ethylene-based resin composite particle containing the hydrophobic filler therein. The present invention also provides an ethylene-based resin composite particle produced by the afore-mentioned process.
    • 本发明的目的是提供一种具有小尺寸近似球形的乙烯基复合树脂复合颗粒,其包含均匀分散在其中的功能性填料,并与其它树脂颗粒或组分相容。 为了实现上述目的,本发明提供一种环保型乙烯类树脂复合粒子的制造方法,其特征在于,包括:(a)将乙烯类聚合物溶解在与水相分离的有机溶剂中,将疏水性填料分散在环境有机物 溶剂形成乙烯基聚合物在有机溶剂中的溶液; (b)将在步骤(a)中获得的溶液乳化在含非离子表面活性剂的水溶液中; (c)加热步骤(b)中获得的乳液以除去有机溶剂; 和(d)在其中回收含有疏水性填料的乙烯系树脂复合体。 本发明还提供了通过上述方法制备的乙烯类树脂复合颗粒。
