【発明の詳細な説明】 （産業上の利用分野） この発明は、化粧パフ用スポンジゴムの製造方法に関
し、特にはリキッドファンデーションに適する化粧パフ
用スポンジゴムの製造方法を提供せんとするものであ
る。Description: TECHNICAL FIELD The present invention relates to a method for producing a sponge rubber for a cosmetic puff, and more particularly to a method for producing a sponge rubber for a cosmetic puff suitable for a liquid foundation. .
（従来技術） 化粧パフは、肌触りの良さ等から連続気泡構造のスポ

多用されている。ところが、リキッドファンデーション
用の化粧パフとしては、パフ内にリキッドファンデーシ
ョンが浸透し難いものが好ましい。(Prior Art) For cosmetic puffs, those made of sponge rubber or soft urethane foam having an open-cell structure are often used because of their good touch. However, a cosmetic puff for a liquid foundation is preferably a cosmetic puff that does not easily penetrate the liquid foundation into the puff.

くなったり、品質にバラツキを生じたり、パフの製造作
業に手間取る等の問題がある。Therefore, in some cases, a plastic film is bonded to the surface of sponge rubber or flexible polyurethane foam having an open-cell structure, or a molten film is formed on the surface of flexible polyurethane foam having an open-cell structure to form a cosmetic puff for liquid foundation. It has been done. However, in this case, there is a problem that the flexibility of the puff surface is impaired, the usability is deteriorated, the quality is varied, and the puff manufacturing operation takes time.

面で劣る等の問題があり、化粧パフとしては好ましいと
は言いがたかった。On the other hand, in recent years, it has been proposed to use a silicone-based sponge rubber having a closed cell structure as a decorative puff. However, this is not only lacking in oil resistance to the silicone oil used as a raw material of the liquid foundation, but also has a problem in that the sponge side surface cannot be polished when the puff shape is formed due to low physical strength and low hardness. There are problems such as inferior safety and hygiene due to peroxide vulcanization, and it is hard to say that it is preferable as a cosmetic puff.

せんとするものである。(Problems to be Solved by the Invention) Accordingly, in view of the above points, the present invention does not involve penetration of a liquid foundation, has excellent oil resistance to a silicone-based oil agent as a raw material of the liquid foundation, and has a physical property strength of a sponge having an open-cell structure. It is an object of the present invention to provide a method for producing a sponge rubber for cosmetic puffs equivalent to rubber safely and easily.

To 0 parts by weight, 3.0 to 6.5 parts by weight of pp'-oxybis-benzenesulfonylhydrazide as a foaming agent, 30 to 40 parts by weight of a liquid nitrile rubber as a plasticizer, and a rubber compounding agent such as a vulcanizing agent and an accelerator are added. The mixed raw material is filled in a closed mold at a filling rate of 80 to 100%, semi-vulcanized by primary vulcanization, and then completely vulcanized by secondary vulcanization to form a sponge rubber for cosmetic puff. Was to be manufactured.
原料ゴムとして用いるニトリルゴム（NBR）は、リキ
ッドファンデーションの原料であるシリコーン油による
パフの膨潤を防ぎ、耐油性を向上させる作用がある。Nitrile rubber (NBR) used as a raw rubber has an effect of preventing swelling of puff by silicone oil, which is a raw material of a liquid foundation, and improving oil resistance.

る。Pp'-oxybis-benzene-sulfonylhydrazide (OBSH) used as a foaming agent has an effect of forming an odorless and non-toxic fine sponge rubber. And that p
-Foaming by changing the blending amount of p'-oxybis-benzene-sulfonylhydrazide (OBSH) between 3.0 to 6.5 (preferably 3.5 to 6.0) parts by weight per 100 parts by weight of nitrile rubber (NBR) The size of the bubbles of the sponge rubber obtained can be adjusted without impairing the balance, and the hardness and feel of the sponge rubber can be made desired. That is, if the amount of the foaming agent is reduced, the bubbles become larger, and if the amount of the foaming agent is reduced, the bubbles become finer.

ンジゴムの品質を一定にする作用もある。Liquid nitrile rubber used as plasticizer (liquid NBR)
Unlike the phthalic acid-based plasticizer DOP, is not extracted into a liquid foundation and has an effect of preventing shrinkage of the obtained sponge rubber. Further, the compounding amount of the liquid nitrile rubber is 30 to 40 parts by weight with respect to 100 parts by weight of the nitrile rubber (NBR).
Because of the parts by weight, the hardness of the sponge rubber obtained could be optimized for a cosmetic puff. In addition, liquid nitrile rubber has good compatibility with nitrile rubber (NBR), so that it is difficult to separate in a mixed raw material, and also has an effect of keeping the quality of sponge rubber obtained constant.

できる。On the other hand, when the filling rate of the mixed raw material in the closed mold at the time of vulcanization is changed between 80 to 100%, the obtained sponge rubber is completely changed from one having a closed cell structure mainly having an open cell structure to a completely closed cell structure. To a closed cell structure. Therefore, for a liquid foundation with a high viscosity that is difficult to penetrate into the puff, a sponge rubber mainly composed of a closed-cell structure having a partially open-cell structure is formed to enhance the foundation retention of the decorative puff surface or to increase the viscosity of the other side. For a low liquid foundation, a sponge rubber having a completely closed cell structure can be formed to prevent the foundation from penetrating into the puff.
また加硫を第１次加硫と第２次加硫の二段階に分けて
行うため、均一な気泡構造からなるスポンジゴムを形成
することができる。Further, since the vulcanization is performed in two stages of the primary vulcanization and the secondary vulcanization, a sponge rubber having a uniform cell structure can be formed.
