溶融状態にある熱可塑性樹脂中に前記セルロース分散液を添加し、溶融混練して混練物を得る第二の工程、及び
第二の工程で得られた混練物から分散媒を除去して樹脂組成物を得る第三の工程、
をこの順に含み、
第二の工程におけるセルロース分散液の添加を、前記溶融状態にある熱可塑性樹脂の温度における水の蒸気圧以上の圧力で実施する、樹脂組成物の製造方法。 A method for producing a resin composition containing a polyolefin resin, cellulose, and a surfactant .
The polyolefin-based resin contains an acid-modified polyolefin-based resin.
The cellulose is a cellulose fiber having a diameter of less than 1 μm, a cellulose whisker having a diameter of less than 1 μm, or a mixture thereof.
The method is
The first step of preparing a cellulose dispersion liquid containing a dispersion medium containing water as a main component and cellulose dispersed in the dispersion medium.
The second step of adding the cellulose dispersion liquid to the molten thermoplastic resin and melt-kneading to obtain a kneaded product, and removing the dispersion medium from the kneaded product obtained in the second step to form a resin composition. The third process of getting things,
In this order,
A method for producing a resin composition, wherein the addition of the cellulose dispersion liquid in the second step is carried out at a pressure equal to or higher than the vapor pressure of water at the temperature of the thermoplastic resin in the molten state.
