本発明は、発泡性の著しく高い塩化ビニル系樹脂組成物
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vinyl chloride resin composition with extremely high foamability.
災来夏伎街
乳化重合によって得られるポリ塩化ビニルと可塑剤とか

泡させて、塩化ビニル系樹脂発泡製品を製造することは
、既によく知られている。Plastisol made of polyvinyl chloride and a plasticizer obtained by emulsion polymerization is mixed with a blowing agent such as azodicarbonamide to form a composition, which is heated and melted and foamed to form a vinyl chloride-based composition. It is already well known to produce resin foam products.
しかしながら、従来、かかる塩化ビニル系樹脂組成物を
用いて、高発泡倍率の製品を得ることは困難であった。However, conventionally, it has been difficult to obtain products with a high expansion ratio using such vinyl chloride resin compositions.
上記組成物を加熱し、ゲル化発泡させる際に、セルが相

めに、得られる発泡製品に空洞、大きい凹凸、層割れ等
を生じ、弾性を失なうと共に、不規則なセル構造を有す
ることとなるからである。When the above-mentioned composition is heated to gel and foam, the cells often coalesce together or are destroyed, resulting in cavities, large irregularities, layer cracks, etc. in the resulting foamed product. This is because it loses elasticity and has an irregular cell structure.
そこで、従来、上記したなような問題を解決するために
、発泡剤と共に種々の発泡助剤を併用することが行なわ

テアリン酸、フタル酸等の有機酸の金属塩、特に、亜鉛
塩が知られているが、しかし、尚、十分に高い発泡倍率
を有する発泡製品を得ることは困難であった。Therefore, in order to solve the above-mentioned problems, conventionally, various foaming aids have been used together with the foaming agent. For example, the foaming aid known as "kitsuka" lowers the decomposition temperature of chemical foaming agents and effectively foams them even at low temperatures. Metal salts of acids, in particular zinc salts, are known, but it has still been difficult to obtain foamed products with a sufficiently high expansion ratio.
そこで、例えば、特開昭５７−１０９８３３号公報には
、プラスチゾルにアゾジカルボンアミドと共に、キツカ
ーとして、平均粒子径０．２７μｍ以下の微細酸化亜鉛
を配合してなる高発泡性樹脂縫放物が提案されている。Therefore, for example, JP-A-57-109833 proposes a highly foamable resin sewing product made by blending fine zinc oxide with an average particle size of 0.27 μm or less as a binder in plastisol together with azodicarbonamide. has been done.
しかし、上記公報によれば、平均粒子径０．１５μｍの
酸化亜鉛を用いた例までは、記載があるものの、平均粒
子径が０．１５μｍよりも小さい超微細酸化亜鉛を用い
た例はなく、勿論、そのような超微細酸化亜鉛を用いた
場合の効果については、何らの記載もない。However, according to the above publication, although there is a description of an example using zinc oxide with an average particle size of 0.15 μm, there is no example using ultrafine zinc oxide with an average particle size smaller than 0.15 μm. Of course, there is no description of the effects of using such ultrafine zinc oxide.
他方、平均粒子径が０．１５μｍまでの微細酸化亜鉛を
用いても、発泡条件や用途によっては、発泡倍率が尚、
不十分であって、−層、高部倍率を有する発泡製品を得
る方法が強く要望されている。On the other hand, even if fine zinc oxide with an average particle size of up to 0.15 μm is used, the foaming ratio may still be low depending on the foaming conditions and application.
There is a strong need for a method of obtaining foamed products with poor, -layer, high area magnification.

The present invention was achieved by discovering that by melting and foaming, it is possible to obtain a polyvinyl chloride resin foam product with a high expansion ratio that has not been achieved conventionally.

荒れが生じる。Furthermore, the resin composition according to the present invention contains ultrafine zinc oxide having an average particle diameter of 0.05 μm or less as a binder in an amount of 1 to 2 parts by weight based on 100 parts by weight of the vinyl chloride resin. If the amount of ultrafine zinc oxide is less than 1 part by weight per 100 parts by weight of the vinyl chloride resin, the foam will not function sufficiently as a filler, making it impossible to obtain a product with a high expansion ratio. However, when an excessive amount exceeding 2 parts by weight is blended, cells become rough when the resin composition is foamed.
