ビニル系樹脂組成物に関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a vinyl chloride resin composition for foaming, and more specifically, it is suitable for obtaining a foam having excellent heat resistance and a smooth surface. This invention relates to a foaming vinyl chloride resin composition that has good foaming start-up.
く゛従来の技術〉
塩化ビニル系樹脂の発泡体は、安価で、弾性、耐水性、

れたものも上市されている。<Conventional technology> PVC resin foams are inexpensive, have elasticity, water resistance,
Due to its excellent chemical resistance, it is widely used in wall materials, furniture, foamed leather, etc., and products with printed surfaces and aesthetic treatments are also on the market.
ところで、塩化ビニル系樹脂は１００℃以上の温度に長
時間さらすと熱により脱塩酸反応を起こして劣化するが
、塩化ビニル系樹脂の加工温度は、軟質塩化ビニル系樹
脂の場合で１５０〜１７０℃、硬質塩化ビニル系樹脂の
場合で１６０〜２００℃にも及ぶ。By the way, if vinyl chloride resin is exposed to temperatures of 100°C or higher for a long time, it will undergo a dehydrochloric acid reaction due to heat and deteriorate, but the processing temperature for vinyl chloride resin is 150 to 170°C in the case of soft vinyl chloride resin. In the case of hard vinyl chloride resin, the temperature reaches 160 to 200°C.
このため、塩化ビニル系樹脂の発泡体の製造においては

成することによって製造される。For this reason, in the production of polyvinyl chloride resin foams, heat stabilizers are used in addition to chemical blowing agents to prevent thermal decomposition of the resin. In other words, vinyl chloride resin foam is generally made by kneading a composition of vinyl chloride resin, heat stabilizers, blowing agents, and if necessary, plasticizers, fillers, etc., and gelling it at a relatively low temperature. The foaming agent is then heated to increase the temperature to gasify the blowing agent by thermal decomposition to form a large number of pores.

場合などにあっては、さらにインクのりが良いことが要
求される。In this way, the vinyl chloride resin composition for foaming must not only have a good foaming start-up to the extent that it can be industrialized, but also the resulting foam must have excellent heat resistance. In addition to wrinkles, when applying color and patterning, even better ink adhesion is required.

Agents are being developed and studied, such as combinations of one metal soap type alone, combinations of two or more types with synergistic effects, and combinations of metal soap types and non-metal soap types. Are known.

(3) Ink adhesion was poor because the surface of the foam obtained lacked smoothness.

た。As a result of extensive research, the present inventors have found that if a vinyl chloride resin composition containing a predetermined amount of a stabilizer made by blending zinc acetate and liquid potassium carboxylate in a predetermined ratio is used as a foaming raw material, It has been found that the above problems can be solved.

にある。The present invention has been made based on this knowledge, and its purpose is to provide a foamed product that has good foaming L7 rise, excellent heat resistance, and a smooth L7 surface. The present invention provides a vinyl chloride resin composition for use in industrial applications.
〈課題を解決するための手段〉
上記目的を達成するための本発明に係る発泡用塩化ビニ
ル系樹脂組成物は、酢酸亜鉛と液状カルボン酸カリウム
とが重量比１：５〜５：１の割合で配合されてなる安定
剤を塩化ビニル系樹脂１００重量部に対して０，３〜１
０．０重量部八有するものである。<Means for Solving the Problems> In order to achieve the above object, the vinyl chloride resin composition for foaming according to the present invention contains zinc acetate and liquid potassium carboxylate in a weight ratio of 1:5 to 5:1. 0.3 to 1 of the stabilizer blended with 100 parts by weight of vinyl chloride resin
It contains 0.0 part by weight.
本発明に係る組成物において、酢酸亜鉛と液状カルボン
酸カリウムとの重量比が１＝５〜５：】の範囲に特定さ
れるのは、重量比１：５未満の場合、発泡倍率が低下し
てしまうからであり、重量比５：１を越えた場合、耐熱
性、平滑性が悪くなって１，まうからである。In the composition according to the present invention, the weight ratio of zinc acetate and liquid potassium carboxylate is specified to be in the range of 1=5 to 5:], because if the weight ratio is less than 1:5, the foaming ratio decreases. This is because if the weight ratio exceeds 5:1, heat resistance and smoothness will deteriorate, resulting in curling.
カルボン酸カリウムを液状のものに特定したのは、塩化
ビニル系樹脂への分散性に優れ、発泡剤の分解を促進し
、発泡の越ち上がりを良くするとともに、均一なセルを
有する発泡倍率の高い発泡体を得るためである。The reason why potassium carboxylate was specified as a liquid is that it has excellent dispersibility in vinyl chloride resin, promotes the decomposition of the blowing agent, improves the foaming rate, and has uniform cells and a high expansion ratio. This is to obtain a highly foamed product.

表より明らかなように、本発明に係゜る発泡用塩化ビニ
ル系樹脂組成物より得られる発泡体（実施例１〜３）は
、耐熱性及び平滑性に優れ、高い経時的発泡倍率及び白
色度を有することが分る。(Hereinafter, blank space) As is clear from the table, the foams (Examples 1 to 3) obtained from the foamable vinyl chloride resin composition of the present invention have excellent heat resistance and smoothness, and have a high aging resistance. It can be seen that it has a desirable foaming ratio and whiteness.
これに対して、酢酸亜鉛と液状カルボン酸カリウムとの
組成重量比が５：１を越える組成物より得られる発泡体
は（比較例１）は、耐熱性が極めて悪く（黒化）、平滑
性に劣り、白色度が低い。On the other hand, the foam obtained from a composition in which the weight ratio of zinc acetate and liquid potassium carboxylate exceeds 5:1 (Comparative Example 1) has extremely poor heat resistance (blackening) and poor smoothness. whiteness is low.
また、４０〜６０秒経過後の初期の発泡倍率は実施例１
のものと同程度であるものの、８０〜１００秒経過後の
中期〜終期の発泡倍率が低いことが分る。In addition, the initial foaming ratio after 40 to 60 seconds was Example 1.
It can be seen that the foaming ratio in the middle to final stage after 80 to 100 seconds is low, although it is comparable to that of the previous example.
また、酢酸亜鉛と液状カルボン酸カリウムとの組成重量
比が１：５未満の組成物より得られる発泡体（比較例２
）は、平滑性は実施例１のものと同程度であるものの、
発泡倍率が低く、白色度及び耐熱性（淡黄色）について
も実施例１のものに比べて劣っている。In addition, a foam obtained from a composition in which the composition weight ratio of zinc acetate and liquid potassium carboxylate is less than 1:5 (Comparative Example 2
), although the smoothness is comparable to that of Example 1,
The foaming ratio is low, and the whiteness and heat resistance (light yellow) are also inferior to those of Example 1.
さらに、酢酸亜鉛に代えてオクチル酸亜鉛を配合した組
成物より得られる発泡体（比較例３）は、１００秒経過
後の発泡倍率、平滑性、白色度は実施例１のものと同程

立ち上がりが悪いことが分る。Furthermore, the foam obtained from the composition containing zinc octylate instead of zinc acetate (Comparative Example 3) had the same level of expansion ratio, smoothness, and whiteness as those of Example 1 after 100 seconds. It can be seen that the heat resistance of that product is poor (brown color) and that the foaming process is slow.
以上の結果から、比較例１〜３における組成物には、一
長一短があるのに対して、実施例１の組成物は、発泡用
組成物として満足のいくものであることが分る。From the above results, it can be seen that the compositions of Comparative Examples 1 to 3 have advantages and disadvantages, whereas the composition of Example 1 is satisfactory as a foaming composition.
