Abstract
A method for manufacturing a resin composition which comprising a thermoplastic resin and inorganic particles having major axes less than 1 μm and aspect ratios in a range of from 3 to 1000 and dispersant both of which are frozen and dried at a temperature lower than 30° C. below the freezing point by freeze vacuum drying. This resin composition is hard to cause agglutination of anisotropic particles having large aspect ratios.
Claims6
A resin composition comprising a thermoplastic resin and inorganic particles having major axes less than 1 μm and aspect ratios in a range of from 3 to 1000 and dispersant both of which are frozen and dried at a temperature lower than 30° C. below the freezing point by means of freeze vacuum drying before blended with said thermoplastic resin.
A method for manufacturing resin composition which comprises a thermoplastic resin and inorganic particles having major axes less than 1 μm and aspect ratios in a range of from 3 to 1000 and dispersant blended with said thermoplastic resin, said resin composition manufacturing method comprises the steps of:
- preparing a dispersion liquid of said inorganic particles and said dispersant dispersed in a solvent;
- freezing and drying said dispersion liquid at a temperature lower than 30° C. below the freezing point by means of freeze vacuum drying;
- and
- blending said inorganic particles and said dispersant with said thermoplastic resin.
