本発明は熱成形時の樹脂の流れ性を改良したスチレン系
樹脂組成物に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a styrenic resin composition that has improved resin flowability during thermoforming.

酸エステルがある。(Prior Art) Commonly used lubricants include metal soaps such as zinc stearate and calcium stearate, bis fatty acid amides such as N,N''-bissteph0ethylene dihumine, stearamide and erucamide. There are fatty acid esters such as fatty acid 7mide, stearyl stearate, and hydrogenated beef tallow oil.

さらに最終製品への熱成形時に特に高滑性を必要とする
場合にはその成形時に滑剤を追加する方法、添加する顔
料に滑剤を添加しておく方法などもある。There are two methods for incorporating a lubricant into styrenic resin: a method of adding the lubricant during the polymerization reaction, and a method of adding the lubricant together with additives such as stabilizers after polymerization and thermoforming it into a pellet shape.
Furthermore, if particularly high lubricity is required during thermoforming into a final product, there is a method of adding a lubricant during the molding, or a method of adding a lubricant to the pigment to be added.

形品の表面に傷がついたり、表面のつやが失われろ。[If the invention seeks to solve this problem] When injection molding a molded product with a complex shape or a large molded product, if the flowability of the resin is poor, the amount of tung fat injected into the mold will be too long before it fills the metal. It takes time and reduces productivity,
In addition, some of the molten resin may solidify before it fills the mold, making it impossible to obtain a molded product in the designed shape.
Furthermore, the surface of molded products may be scratched or lose its luster due to flash and flow mark phenomena.

煙＋１が多くなって作業環境が悪くなりたり、成形品の
熱変形温度が低下するなどの問題が発生する。If the thermoforming temperature is raised to improve the flowability of the resin, problems such as coloring of the resin and increased energy consumption occur. Furthermore, if too much lubricant is added, problems such as increased smoke generation during thermoforming, which worsens the working environment, and a decrease in the heat distortion temperature of the molded product, occur.
本発明は滑剤の含有率を従来より増加させることなしに

とを目的とする。An object of the present invention is to provide a styrenic resin composition that has improved flowability without increasing the lubricant content compared to conventional compositions.
