Abstract
Official abstract text for this publication.
The present invention provides a granulated resin additive composition which comprises an aromatic metal phosphate salt and a phenolic antioxidant and, when blended in a resin, allows the resulting resin composition to have excellent mechanical strengths and transparency. The granulated resin additive composition is characterized by comprising a phosphate salt compound represented by the Formula (I), a phenolic antioxidant and a fatty acid calcium salt, in which granulated resin additive composition the content of the fatty acid calcium salt is 1 to 6 parts by mass with respect to 100 parts by mass of the granulated resin additive composition.
First claim
Opening claim text (preview).
The invention claimed is: 1. A granulated resin additive composition, consisting essentially of a phosphate salt compound, represented by the Formula (Compound No. 1): a phenolic antioxidant, wherein the phenolic antioxidant is tetrakis {3(3, 5-di-tert-butyl-4-hydroxyphenyl)propionyloxymethyl }methane, and a fatty acid calcium salt, wherein the total amount of the phosphate salt compound and the phenolic antioxidant is not less than 95% by mass of the granulated resin additive composition; wherein the fatty acid calcium salt is 2 to 5 parts by mass with respect to 100 parts by mass of said granulated resin additive composition; wherein the granulated resin additive composition consists essentially of, with respect to 100 parts by mass thereof, 20 to 80 parts by mass of said phosphate salt compound represented by said Formula (I) and 20 to 80 parts by mass of said phenolic antioxidant; and wherein the fatty acid calcium salt is calcium stearate. 2. The granulated resin additive composition according to claim 1 , which is for a polyolefin-based resin. 3. The granulated resin additive composition according to claim 1 , which consists essentially of, with respect to 100 parts by mass thereof, 20 to 40 parts by mass of said phosphate salt compound represented by said Formula (I) and 55 to 80 parts by mass of said phenolic antioxidant. 4. A method of adding a resin additive composition to a resin, wherein a resin additive composition which consists essentially of a phosphate salt compound represented by the Formula (Compound No. 1): a phenolic antioxidant, wherein the phenolic antioxidant is tetrakis {3(3,5-di-tert-butyl-4-hydroxyphenyl)propionyloxymethyl }methane, and a fatty acid calcium salt is made into granules containing 2 to 5 parts by mass of said fatty acid calcium salt with respect to 100 parts by mass of said resin additive composition and then added to a resin; wherein the total amount of the phosphate salt compound and the phenolic antioxidant is not less than 95% by mass of the resulting granules; wherein the resin additive composition consists essentially of, with respect to 100 parts by mass thereof, 20 to 80 parts by mass of said phosphate salt compound represented by said Formula (I) and 20 to 80 parts by mass of said phenolic antioxidant; and wherein the fatty acid calcium salt is calcium stearate. 5. The method according to claim 4 , wherein the resin additive composition consists essentially of, with respect to 100 parts by mass thereof, 20 to 40 parts by mass of said phosphate salt compound represented by said Formula (I) and 55 to 80 parts by mass of said phenolic antioxidant.
