補強の樹脂に比し、成形性補強性が優れている。For example, when a glass flake is mixed with a thermoplastic resin, the two-dimensional reinforcing effect of the glass flake improves tensile strength, bending strength, bending elastic modulus, heat deformation temperature and the like, and a resin having excellent characteristics. Will be obtained. Molded products of such a resin have almost the same mold shrinkage in the resin flow direction and mold shrinkage in the direction perpendicular to the resin flow, so the warpage of the molded product is extremely small, and compared with glass fiber reinforced resin. The moldability and reinforcement are excellent.

Since it is as small as 2 / g, there is a problem that a sufficient reinforcing effect may not be obtained.

Reference numeral 20 in FIG. 1 indicates a single glass flake. ) Is obtained. In this case, the glass flakes may be measured by observing them with a scanning electron microscope, or the glass flakes may be filled in a resin, molded, broken, and the fracture surface thereof may be observed and measured.

使用した場合、十分な補強効果が得られない。The glass flakes according to the present invention have an average thickness of 0.8 to 1.4 μm. And the thickness is 0.3 ~
90% by weight or more of flakes in the range of 3.0 μm are contained. A material containing more than 10% by weight of a material having a thickness of less than 0.3 μm has a high manufacturing cost and is economically disadvantageous. Further, if the content of flakes having a thickness of more than 3.0 μm exceeds 10% by weight, a sufficient reinforcing effect cannot be obtained when used as a resin reinforcing material.

Those containing 90% by weight or more of flakes of m are particularly preferable.

脂の流動性を低下させ、混練し難くなるためである。The particle diameter d of the glass flakes according to the present invention (see FIG. 1) is in the range of 10 to 2000 μm. This is because flakes having a particle size of less than 10 μm have a small reinforcing effect, while flakes having a particle size of more than 2000 μm reduce the fluidity of the resin and make it difficult to knead.

Thereby, the characteristics such as the reinforcing effect of the glass flakes can be improved. As the surface treatment agent, various commercially available surface treatment agents can be adopted. Specific examples of the surface treatment agent include silicon-based coupling agents such as γ-aminopropyltriethoxysilane, vinyltriethoxysilane, and γ-methacryloxypropyltrimethoxysilane, and other titanium-based coupling agents. The amount of these surface treatment agents used is 0.05 to 0.20% by weight based on the weight of the glass flakes, as shown in Examples 3 to 5 below.
