有している。In order to improve this, JP-A-53-121902 discloses a resin molded article molded from a resin composition in which a resin and leather powder are mixed. However, since normal leather powder is fibrous, it is granular. Even if the diameter is reduced, the apparent specific gravity is 0.2 g / cm 3 or less, so when it is contained in the resin, it aggregates and it is difficult to disperse it uniformly.
It has low fluidity and there is a limit to the filling amount of leather powder.
Further, since the adhesiveness between the leather powder and the resin is not good, there is a problem that the physical properties of the resin molded product obtained by blending the leather powder, such as strength, elongation and abrasion resistance, are deteriorated.

本発明の皮革粉は、例えば次に示すような方法で製造す
ることができる。The leather powder of the present invention can be produced, for example, by the following method.
原料皮革を５〜30mm以下に細片化し、これを温度100〜1
20℃、水分含量40〜60重量％程度の条件で10〜60分間で
蒸気加熱して膨潤させ、次いで蒸気加熱した細片を水分
が３重量％以下になるまで乾燥し、次いで乾燥した細片
を好ましくはファインビクトリーミル等を用いて粉砕
し、篩を用いて粒度40メッシュパスのものを分粒する。Raw leather is cut into pieces of 5 to 30 mm or less and the temperature is 100 to 1
Steamed and swelled under conditions of 20 ° C and water content of 40-60% by weight for 10-60 minutes, and then steam-heated strips are dried until the water content is 3% by weight or less, and then dried strips. Is preferably pulverized using a fine Victory mill or the like, and a sieve having a particle size of 40 mesh is sized.
原料皮革としては、クロムなめしなどの処理をされた、
牛皮、豚皮、羊皮等が好ましく用いられる。また、床
皮、シェービング屑等も用いることができる。As the raw material leather, chrome tanned etc. have been treated,
Cowhide, pig skin, sheep skin and the like are preferably used. Further, floor skin, shaving waste, and the like can also be used.
原料皮革には一般に原料皮の地油や皮革を加工する際に
加脂工程で加えられた油脂が含まれているため、皮革粉
の脱脂処理を行うことが好ましい。この処理は通常溶剤
を用いた抽出により行なわれるが、高温加熱を伴わない
方法が皮革粉の変質（ゼラチン化）防止のためには好ま
しい。溶剤としては、クロロホルム、ベンゼン、アセト
ン、四塩化炭素、トリクロロエチレン、ジクロルメタ
ン、トルクロルトルフルオルエタン、ジブロムテトラフ
ルオルエタン、ヘキサン、石油エーテル、石油留分（DL
N）等が用いられる。Since the raw material leather generally contains the base oil of the raw material leather and the fats and oils added in the fatliquoring step when processing the leather, it is preferable to degrease the leather powder. This treatment is usually carried out by extraction with a solvent, but a method not accompanied by high temperature heating is preferable for preventing the alteration (gelatinization) of leather powder. Examples of the solvent include chloroform, benzene, acetone, carbon tetrachloride, trichloroethylene, dichloromethane, tolchlortolufluoroethane, dibromotetrafluoroethane, hexane, petroleum ether, petroleum fraction (DL
N) etc. are used.
脱脂処理は動物性油脂の含有量が好ましくは１重量％以
下、好ましくは0.8〜0.2重量％とする。この含有量が１
重量％を超えると、この皮革粉を樹脂に配合して加熱溶
融した場合に悪臭が発生し成形が困難になるとともに、
得られた成形品の色目、耐熱性などの低下、油脂のブリ
ードが生じ好ましくない。また、0.2重量％未満になる
と発泡が生じやすくなり、上記範囲にすることが好まし
い。In the degreasing treatment, the content of animal fat is preferably 1% by weight or less, preferably 0.8 to 0.2% by weight. This content is 1
If the content exceeds 10% by weight, when this leather powder is mixed with a resin and heated and melted, a bad odor is generated and molding becomes difficult.
The resulting molded article is unfavorable in that the color tone, heat resistance and the like are deteriorated and fat and oil bleed. Further, if it is less than 0.2% by weight, foaming tends to occur, so that it is preferable to set it in the above range.
皮革粉の粒度が40メッシュ篩を通過しないものは、樹脂
組成物の成形性、成形品の外観に劣る。より好ましくは
60メッシュ篩を通過したものが用いられる（ASTM式標準
篩）。If the grain size of the leather powder does not pass through the 40-mesh sieve, the moldability of the resin composition and the appearance of the molded product are poor. More preferably
The one that has passed through a 60 mesh sieve is used (ASTM type standard sieve).
また、皮革粉の見掛比重が0.3g／cm3未満であると成形
性、成形品の外観に劣り、また、樹脂に対する充填量を
多くすることができないとともに混合が非常に困難とな
る。より好ましくは0.35〜0.6g／cm3のものが用いられ
る。If the apparent specific gravity of the leather powder is less than 0.3 g / cm 3 , the moldability and the appearance of the molded product will be poor, and the amount of resin will not be increased, and mixing will be very difficult. More preferably, 0.35-0.6 g / cm 3 is used.
尚、本発明の改質皮革粉を得るための皮革の脱脂工程は
特に制限されるものではない。たとえば、原料皮革を
粗粉砕して乾燥した後、蒸気加熱処理して乾燥した
後、微粉砕工程の後、篩分級の後などがある。この
場合を採用すれば、脱脂効率は低いものの、処理後
の固液分離性が良好であり、を採用すれば、固液分
離性は低いものの、脱脂効率が高く、また抽出溶剤の選
択によっては、脱水を同時に行える特徴がある。The leather degreasing step for obtaining the modified leather powder of the present invention is not particularly limited. For example, the raw leather may be roughly crushed and dried, then steam-heated and dried, followed by a fine crushing step and after sieving. If this case is adopted, although the degreasing efficiency is low, the solid-liquid separation property after the treatment is good, and if is adopted, the solid-liquid separation property is low, but the degreasing efficiency is high, and depending on the selection of the extraction solvent. The feature is that dehydration can be performed at the same time.
尚、ここで用いられる見掛比重は、空気混入かさ比重
（Aerated Bulk Density）である。篩を振動させて皮
