ある。[Detailed Description of the Invention] This invention relates to a vinyl chloride resin (hereinafter abbreviated as PVC) composition, and its purpose is to improve the impact resistance and weather resistance of the PVC composition without impairing its various properties. It is something.

This invention was completed by elucidating the factors that affect impact resistance and weather resistance. In summary, this invention improves the impact resistance of a PVC composition by blending 2 to 15 PHR of ultrafine calcium carbonate and 0.3 to 3.0 PHR of dibasic zinc maleate to a hard vinyl chloride resin composition. and improve weather resistance.
つぎに、この発明を詳しく説明する。Next, this invention will be explained in detail.

酸カルシウムの添加量が前記範囲を下限において外れる
と耐候性が不十分となる。As a result of a detailed study on these, we found that the hard PVC composition contains 2 to 15 PHR of ultrafine calcium carbonate (colloidal calcium carbonate) and 0.3 to 3.0 PHR.
It has been found that by blending HR's dibasic zinc maleate, the impact resistance and weather resistance can be significantly improved without impairing the various properties of the vinyl chloride composition. If the amount of ultrafine calcium carbonate added is outside the above range at the lower limit, the weather resistance will be insufficient.
また、前記範囲を上限において外れると成形トルクの増
大が起り好ましくない。二塩基性マレイン酸亜鉛の添加

少なく耐熱安定性が害される。Further, if the upper limit is outside the above range, the molding torque will increase, which is not preferable. If the added amount of dibasic zinc maleate deviates from the above range at the lower limit, the effect of improving weather resistance will be small and heat resistance stability will be impaired.

施例および比較例について説明する。Further, if the upper limit exceeds the above range, the heat deformation resistance will decrease. In this invention, the means for kneading the raw materials and the molding method (extrusion molding, etc.) are conventional methods. Further, the conditions for producing or molding the composition may be the same as usual. As described above, the PVC composition of the present invention includes a hard PVC composition, 2 to 15 PHR of ultrafine calcium carbonate, and 0.3 PHR of ultrafine calcium carbonate.
Since ~3.0 PHR of dibasic zinc maleate is blended, the impact resistance and weather resistance can be significantly improved without impairing the various properties of the PVC composition. Next, Examples and Comparative Examples will be described.

験を行ない、次式にもとづいて引張り衝撃強度を計算し
たものである。That is, a hard PVC composition was obtained according to the conventional method using the formulations shown in the table below. The impact strength was examined using a tensile impact tester designed and manufactured in accordance with ASTM Dl822, and the weather resistance was examined based on the degree of whitening, and the results are shown in the table. Note that considerations 1 to 3 are comparative examples. The tensile impact strength was calculated using the above-mentioned tensile impact testing machine (with a capacity of 30 kg-1) on a sample set to a thickness of 1 nm, and based on the following formula.
そして、これの数値が大きいものほど耐衝撃性が大きい
。つぎに、白化度ΔＶは、マンセル表色系のＶ値（明度

のｖ値の差である。The higher the value, the higher the impact resistance. Next, the degree of whitening ΔV is the difference in the v value between the initial state and the sample after six months of outdoor exposure, using the V value (corresponding to brightness) of the Munsell color system.
