A resin additive composition that includes a resin additive having a melting point of 100°C or less and thereby is improved in handleability and is highly held in a resin is provided. The resin additive composition is prepared by impregnating a powdery inorganic material (B) having an oil absorption of 150 mL/100 g or more and preferably 200 mL/100 g or more with a resin additive (A) having a melting point of 100°C or less in advance. Examples of the resin additive (A) include an antioxidant, an ultraviolet absorber, a light stabilizer, and mixtures thereof. Examples of the powdery inorganic material (B) include silica, aluminium silicate, hydrotalcite, calcium silicate, magnesium aluminometasilicate, and mixtures thereof.
本发明提供了一种树脂添加剂组合物,其中包括一种熔点为 100°C 或更低的树脂添加剂,从而改善了操作性,并在树脂中具有很高的保持力。该树脂添加剂组合物的制备方法是,预先将吸油量为 150 mL/100 g 或以上、最好为 200 mL/100 g 或以上的粉状无机材料(B)浸渍到熔点为 100°C 或以下的树脂添加剂(A)中。树脂添加剂(A)的例子包括抗氧化剂、紫外线吸收剂、光稳定剂及其混合物。粉状无机材料(B)的例子包括二氧化硅、硅酸铝、水滑石、硅酸钙、铝硅酸镁及其混合物。
