Problems solved by technology

After the air is enclosed again, the internal air volume increases, and the improvement effect of the kneading operation is destroyed, and the production efficiency decreases.
In addition, although it is volume reduction, dust is generated when the inorganic filler is moved from the paper bag or rubber container to the hopper or mixer, and there are problems such as deteriorating the working environment.

Embodiment

[0040] The following examples are given to illustrate the present invention in more detail, but the present invention is not limited by these examples. All the embodiments are implemented using standard technologies, or parts that can be implemented, except for other details described in detail, which are well-known and commonly used technologies for those in the industry. Implementation convenience 1

[0041] Mix talc particles with an average primary particle size of 1.8 μm, 3,900 g of HIFIRA #5000PS (manufactured by Matsumura Sangyo Co., Ltd.), and 100 g of bentonite (manufactured by Hosun Co., Ltd.) with a 30-liter blender for about 5 minutes, and then add it as a wetting agent 1600g of water was mixed for about 30 minutes. Then, the mixture is extruded from a sieve with an aperture of φ1.2mm by a basket-type sieve forming machine, and then granulated into a cylindrical shape with an average length of about 2mm and a diameter of about 1.2mm (length / diameter ratio 1), at 9...

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, ...
