Title:
繊維複合樹脂組成物の製造方法
Document Type and Number:
Japanese Patent JP7264340
Kind Code:
B2
Abstract:
For a fiber compound resin composition, a melt-kneading process is performed together with a base resin 1, a dispersant, etc. without performing a pretreatment through wet dispersion for the purpose of defibration treatment and modification treatment of a fibrous filler 2. As a result, each fiber of the fibrous filler 2 is defibrated from end portions in a fiber length direction, while a dispersant component put in at the same time is more selectively adsorbed to defibrated portions 3 at the end portions defibrated and increased in surface area. As a result, hydrophobization of the defibrated portions 3 is promoted as compared to a non-defibrated portion 4, so that a difference in hydrophobicity is formed in the fiber length direction of the fibrous filler 2. Therefore, even when the fibrous filler 2 is added in large amount, a melt viscosity during molding may be lowered without reducing a strength of a molded article.
