ないとされていた。BACKGROUND OF THE INVENTION When blow molding frosted glass bottles using vinyl chloride resin, crosslinked vinyl chloride resin is exclusively used. Furthermore, foaming in blow bottles occurs due to moisture absorption in the compound or air entrainment due to poor deaeration in the extruder, and foaming was treated as a trouble phenomenon and was considered undesirable.

The present inventors attempted to solve this problem by combining the blowing agent Hotaru, the blow ratio during blow molding, the blow pressure, and the amount of processing aid added, and obtained a blow bottle with a highly decorative appearance. It was extremely successful.

l5Z-6271) is 500-800. When the average degree of polymerization exceeds 800, the melt viscosity generally increases,
This causes thermal decomposition of the polymer due to heat generated during molding. On the other hand, when the average degree of polymerization is less than 500, physical properties such as strength as a bottle are poor, which is not preferable.

から重炭酸ナトリウムを用いるのがよい。Pyrolysis type 7! ! A mechanical blowing agent can be used in combination with the pyrolyzable organic blowing agent. This is because when an inorganic foaming agent is used alone, it is difficult to develop fine foam cells. Examples of the thermally decomposable inorganic blowing agent used in combination include sodium bicarbonate, ammonium bicarbonate, ammonium carbonate, and those containing these as main components. Among these, sodium bicarbonate is preferably used from the viewpoint of toxicity (9) foaming properties, etc.

、発泡セルの破壊を防止し外観光沢を得るものである。As the methacrylic acid ester resin used in the present invention, polymethyl methacrylate or a copolymer resin of methyl methacrylate and ethyl acrylate, acrylonitrile, etc. is used. In terms of foam cell properties and moldability, the preferred degree of polymerization of the methacrylic acid ester resin is 2.000 to 2.000 in terms of polymethyl methacrylate.
30,000. This methacrylic acid ester resin improves the melt viscosity characteristics of the vinyl chloride resin, and when foaming this composition to provide a cell structure, increases the elongation of the vinyl chloride resin, thereby increasing the cell membrane strength. It maintains the foam, prevents the foam cells from being destroyed, and provides a glossy appearance.

．． 5 to 10 parts by weight, preferably 1 to 5 parts by weight. If the amount added is less than 0.5 parts by weight, the membrane strength during foam cell formation cannot be maintained, so even if the foam cells are formed, they may break or re-fuse. In many cases, a uniform and fine foam cell structure cannot be obtained.

発熱による熱分解の発生や透明性が低下するからである
。In the present invention, an MBS (methyl methacrylate/butadiene/styrene copolymer) type or ABS (acrylonitrile/butadiene/styrene copolymer) type reinforcing agent is used. These resins impart impact resistance to the bottle, and are added in an amount of 1 to 30 parts by weight, preferably 3 to 25 parts by weight, per 100 parts by weight of the vinyl chloride resin. If it is less than 1 part by weight, the effect of imparting impact resistance will be poor;
This is because if the amount exceeds 5 parts by weight, the rigidity of the bottle decreases, thermal decomposition occurs due to heat generated during processing, and transparency decreases.

、ブロ一時の空気圧で変形させられる。In the present invention, the amount of the blowing agent added is 0.001 to 1 part by weight per 100 parts by weight of the vinyl chloride resin, and depending on the combination of the amount of the blowing agent added and the molding pressure during blow bottle molding. Bottles with appearances ranging from a transparent die-A cut glass-like bottle to a milky-white and soft-feeling foam bottle can be obtained. That is, in the blow bottle molding process, the parison produced from the die using the compound containing the blowing agent has tightly bound spherical cells. The bubbles in the parison grow by the time of blowing and are deformed by the air pressure during blowing.
その結果、ボトル内面は凹凸となり、外面は金型に押し
・１１けられ比較的平面で艶のあるボトルが得られる。As a result, the inner surface of the bottle becomes uneven, and the outer surface is pressed and dented by the mold, resulting in a relatively flat and glossy bottle.

If the amount of the blowing agent added is less than 0.01 part by weight, the amount of cells generated is small and the shape becomes close to a transparent flat plate, and a die A cut-like appearance cannot be obtained. However, there is not much change in the milky white appearance, which is disadvantageous in terms of cost, and the thermal stability of the vinyl chloride resin is also deteriorated.

発明の効果
本発明組成物によれば、従来不可能視されていた塩化ビ
ニルｔ４１成物に発泡剤を使用し、ダイヤカットガラス
調ないし乳白色真珠状の装飾性に富んだびんが得られ、
化粧品用、薬品用等のびんとして、非常に有用である。Effects of the Invention According to the composition of the present invention, a foaming agent is used in the vinyl chloride T41 composition, which was considered impossible in the past, and a highly decorative bottle with a diamond-cut glass-like or milky white pearl-like appearance can be obtained.
Very useful as bottles for cosmetics, medicines, etc.
また本発明組成物では、架橋塩化ビニルのような特殊塩
化ビニルを使用しないので、製品コストの点でも有利で
ある。Furthermore, the composition of the present invention does not use special vinyl chloride such as crosslinked vinyl chloride, so it is advantageous in terms of product cost.
