【発明の詳細な説明】 ［産業上の利用分野］ 本発明は熱可塑性樹脂又は熱硬化性樹脂成形用の補強材
に係り、特に、優れた補強効果を発揮し得る熱可塑性樹
脂又は熱硬化性樹脂成形用の補強材に関する。TECHNICAL FIELD The present invention relates to a reinforcing material for molding a thermoplastic resin or a thermosetting resin, and particularly to a thermoplastic resin or a thermosetting resin capable of exhibiting an excellent reinforcing effect. The present invention relates to a reinforcing material for resin molding.

途に広く利用されている。[Prior Art] Glass flakes have an aspect ratio (particle size / thickness) of 2 to
1000 pieces of glass flakes have hitherto been widely used as reinforcing materials for thermosetting resins and thermoplastic resins, filling materials for anticorrosion linings, and other applications.

る。For example, if a mixture of glass flakes with a thermosetting resin is ironed or spray-coated on a metal surface,
The glass flakes are oriented in the coating almost parallel to the coated surface,
When 30% by weight of glass flake is mixed with the resin, about 35 to 40 glass flake layers are formed per 1 mm thickness of the coating film. As a result, the path length of the environmental agent such as water or oxygen that penetrates the coating film and reaches the surface of the base material such as a metal is remarkably lengthened, and corrosion by the environmental agent is prevented.

極めて小さくなる。Further, in a composite material in which glass flakes are mixed with a thermoplastic resin, tensile strength, bending strength, bending elastic modulus, heat deformation temperature, dimensional accuracy, etc. are improved due to the two-dimensional reinforcing effect of the glass flakes, and barrier properties are also provided. It is imparted and a resin having excellent properties is obtained. Since the molding shrinkage in the resin flow direction and the molding shrinkage in the direction perpendicular to the resin flow are almost equal, the molded product of the resin reinforced with such flakes is The sled becomes extremely small.

いるのが現状であった。[Problems to be Solved by the Invention] By such a surface treatment with a coupling agent or the like, in particular, a surface treatment with a silane coupling agent, there is no adhesion or adhesion between the glass flake and the matrix resin in the composite material. It is improved to some extent compared to the treated one. However, in the surface treatment with only the coupling agent, the interface between the glass flakes and the resin is brittle, and the affinity between the two is not sufficient, so the adhesive strength and adhesion between the glass flakes and the resin are insufficient, and the resulting composite It cannot be said that the physical properties of the material are sufficiently satisfactory, and there is still room for improvement.
