Example Embodiment

[0039] Example

[0040] The following examples illustrate the present invention in more detail, but the present invention is not limited by these examples. Except for other detailed contents, all the embodiments are implemented using standard techniques or parts that can be implemented. These are well-known and customary techniques for the industry. Implementation 1

[0041] Talc particles with an average primary particle size of 1.8μm, 3900g of Hifila #5000PS (manufactured by Matsumura Sangyo Co., Ltd.), and 100g of bentonite (manufactured by Fengshun Yoko Co., Ltd.) are mixed in a 30-liter blender for about 5 minutes, and then added as a wetting agent Mix 1600g of water for about 30 minutes. Then, the mixture was extruded from a sieve with an aperture of φ1.2mm using a basket sieve forming machine, and then pelletized into a cylindrical shape (length / diameter ratio 1) with an average length of about 2mm and a diameter of about 1.2mm. Airflow drying at a temperature of 1 hour to ...

Abstract

Provided are a granular inorganic filler which is highly effective in improving the physical properties of resins and excellent in working efficiency, working atmosphere, productivity and economical efficiency, a process for producing the filler, and resin compositions excellent in mechanical properties, surface appearance, flame retardance and antiblock properties. The filler is produced by granulating a mixture comprising inorganic filler particles having a mean particle diameter of 0.01 to 20 mum and a binder in such a way as to give an apparent density of 0.1 to 3.0 g/ml and a breakage rate of 5 to 80 wt %. The resin compositions are prepared by adding the granular inorganic filler to resins.

Description

technical field [0001] The present invention relates to a granular inorganic filler, a production method for granulating the inorganic filler with a binder, and a resin composition prepared by blending the granular inorganic filler. Background technique [0002] Utilizing the respective characteristics of various fillers, they are mixed in various thermoplastic resins or thermosetting resins as bulking materials, reinforcing materials, flame retardants, and anti-adhesion materials. As final products, they have been used in garbage bags, washbasins, various It is widely used in various fields such as daily-use products such as plastic miscellaneous products, electric wires, automobiles, and home appliances. In addition, it is known that when an inorganic filler having a small average particle diameter is used, the effect of improving the physical properties of the resin is enhanced. [0003] Generally, various resins and fillers, coloring pigments, stabilizers, dispersants, ...
