More specifically, the present invention relates to a degassed inorganic filler, a resin composition containing the inorganic filler, and a method for producing the same.

【発明の技術的背景並びにその問題点】天然無機質充填
剤叉は合成無機質充填剤を樹脂に混合し、樹脂の各種物
性を向上させる方法としては、種々の方法が知られてい
る。TECHNICAL BACKGROUND OF THE INVENTION AND PROBLEMS THEREFOR Various methods are known for improving various physical properties of resins by mixing natural or synthetic inorganic fillers with resins.
【０００３】例えば、従来では、樹脂と充填剤とが配合

用いて造粒する方法等が採用されている。For example, conventionally, when producing granules in which a resin and a filler are blended, or in which stabilizers, pigments, etc. are further blended as necessary in addition to the resin and filler, For example, a method has been adopted in which these ingredients are mixed using a mixer such as a Henschel mixer, and then granulated using a single screw extruder or the like.
【０００４】このように、樹脂の各種物性を向上させる
際に用いられる無機質充填剤としては、平均粒子径が１
〜１００μ程度であり、嵩比重は０．０７〜０．７程度
のものが一般的である。As described above, inorganic fillers used to improve various physical properties of resins have an average particle diameter of 1.
~100μ, and the bulk specific gravity is generally about 0.07 to 0.7.
【０００５】また、無機質充填剤の内でも、平均粒子径
の小さい充填剤を用いると、樹脂の物性改良効果が高い
ことも公知である。ところで、無機質充填剤粒子内ある
いは無機質粒子相互間には、通常、空隙があり、そこに
空気などの気体が内包されている。[0005] It is also known that among inorganic fillers, the use of fillers with a small average particle diameter is highly effective in improving the physical properties of the resin. Incidentally, there are usually voids within the inorganic filler particles or between the inorganic particles, and gases such as air are encapsulated therein.
【０００６】これらの内部空気が無機質充填剤に沢山存

みに働くのではなく、樹脂供給口（ホッパー）方向など
にも働くため、ホッパーへの供給樹脂量に対する樹脂組
成物の押出量の割合が少なく、生産性が低くなるという
問題点がある。[0006] If a large amount of these internal air exists in the inorganic filler and the bulk specific gravity of the filler is low, the pressurized internal air will be released when the inorganic filler and resin are kneaded or when the kneaded product is granulated. The major effect is not only in the resin extrusion direction of the extruder, but also in the direction of the resin supply port (hopper), so the ratio of the amount of resin composition extruded to the amount of resin fed to the hopper is small, improving productivity. There is a problem that the value becomes low.
【０００７】樹脂組成物の押出量は、樹脂に対する無機
質充填剤の配合割合が多くなるに従って、少なくなる。
かかる傾向は、充填剤の嵩比重が少ない場合に特に著し
い。また、これらの内部空気がある程度、混練物中に存

て混練物に圧力を加えても、空気層の内容積変化となっ
て加圧は吸収されてしまい、この空気圧が押出機の出口
方向への樹脂圧として効果的に働かない。[0007] The extrusion amount of the resin composition decreases as the blending ratio of the inorganic filler to the resin increases. This tendency is particularly remarkable when the bulk specific gravity of the filler is low. In addition, if a certain amount of internal air exists in the kneaded material, even if pressure is applied to the kneaded material from the hopper side of the kneading machine toward the outlet, the internal volume of the air layer changes and the pressure is absorbed. Therefore, this air pressure does not work effectively as resin pressure toward the exit of the extruder.
【０００８】なお、充填剤の嵩比重を高める方法として
は、従来、充填剤をケミカルバインダーあるいは水で固
める方法が知られている。しかしながら、この方法には
下記のような問題点がある。[0008] As a method of increasing the bulk specific gravity of a filler, a method of hardening the filler with a chemical binder or water is conventionally known. However, this method has the following problems.
【０００９】すなわち、（イ）充填剤入り樹脂組成物の

の製造コストがかかりすぎること、等の問題点がある。That is, (a) binder or water comes out of the granules during granulation of the filler-containing resin composition, which interferes with the granulation process; and (b) binder comes out of the granules. Further, there are other problems such as water and the like having an adverse effect on the physical properties of the resin or the appearance of the resin molded product, and (iii) the production cost of granules such as pellets being too high.

If it is less than 4%, the amount of extrudates such as pellets made of the composition containing the filler will not increase significantly, and
If the deaeration rate exceeds 92%, the talc will not be uniformly redispersed even when the composition is kneaded, and the physical properties of the composition, particularly the impact strength, will tend to deteriorate. In addition, if the volume ratio (gas/solid) of gas and solid contained in the inorganic filler is less than 2.0, the talc will not be uniformly redispersed even if the above composition is kneaded, and the physical properties of the composition, especially Impact strength tends to decrease. Further, when this volume ratio (gas/solid) exceeds 6.0, the amount of extrudates such as pellets made of the composition containing the filler tends not to increase significantly.

It is about 0.9, preferably about 0.75 to 0.85. If the bulk specific gravity of the compressed inorganic filler is less than 0.6, the amount of extrudates such as pellets made of the composition containing the filler will not increase significantly, and if the bulk specific gravity is less than 0.6. If it exceeds 9, the talc will not be uniformly redispersed even when the composition is kneaded, and the physical properties of the composition, particularly the impact strength, will tend to deteriorate.

Fillers such as talc that have been redispersed in the material, that is, once compressed and optionally agglomerated, tend to be uniformly dispersed again in the kneaded material during kneading.
