Abstract
Official abstract text for this publication.
A polypropylene resin composition having high transparency and heat-resistance comprises: 100 parts by weight of a matrix resin composition comprising 60 to 70 wt % homo-polypropylene and 30 to 40 wt % random-polypropylene; 0.3 to 0.5 parts by weight of an antioxidant; 0.3 to 0.5 parts by weight of a heat-resistance stabilizer; 0.2 to 0.5 parts by weight of a lubricant; and 0.2 to 0.5 parts by weight of a nucleating agent.
First claim
Opening claim text (preview).
What is claimed is: 1 . A polypropylene resin composition having high transparency and heat-resistance comprising: 100 parts by weight of a matrix resin composition comprising 60 to 70 wt % homo-polypropylene and 30 to 40 wt % random-polypropylene; 0.3 to 0.5 parts by weight of an antioxidant; 0.3 to 0.5 parts by weight of a heat-resistance stabilizer; 0.2 to 0.5 parts by weight of a lubricant; and 0.2 to 0.5 parts by weight of a nucleating agent. 2 . The polypropylene resin composition of claim 1 , wherein the homo-polypropylene has a melt index of 1 to 10 g/10 min and a softening point of 130 to 180° C. 3 . The polypropylene resin composition of claim 1 , wherein the random-polypropylene has a melt index of 10 to 20 g/10 min and a softening point of 100 to 160° C. 4 . The polypropylene resin composition of claim 1 , wherein the antioxidant is a phenol-based compound, a phosphorus compound, or a mixture thereof. 5 . The polypropylene resin composition of claim 1 , wherein the heat-resistance stabilizer is at least one selected from the group consisting of a sulfur-based compound, a phenol-based compound, and a phosphorous-based compound. 6 . The polypropylene resin composition of claim 1 , wherein the lubricant is an olefin-based compound. 7 . The polypropylene resin composition of claim 1 , wherein the nucleating agent is at least one selected from the group consisting of benzylidene sorbitol, methylbenzylidene sorbitol, ethylbenzylidene sorbitol, and di(p-methylbenzylidene) sorbitol.
