Abstract

Official abstract text for this publication.

The present invention provides a chlorinated vinyl chloride resin composition for a window frame having excellent properties including moldability, heat resistance, and impact resistance and capable of preventing or reducing deformation such as warpage or damage even after exposure to sunlight for a long time. Provided is a chlorinated vinyl chloride resin composition for a window frame, containing a chlorinated vinyl chloride resin and an infrared reflective pigment.

First claim

Opening claim text (preview).

The invention claimed is: 1. A chlorinated vinyl chloride resin composition for a window frame, comprising: a chlorinated vinyl chloride resin; and an infrared reflective pigment, the infrared reflective pigment containing a silicate compound having a volume average primary particle size of 0.1 to 1.0 μm. 2. The chlorinated vinyl chloride resin composition for a window frame according to claim 1 , wherein the chlorinated vinyl chloride resin has an average degree of polymerization of 500 to 1,000. 3. The chlorinated vinyl chloride resin composition for a window frame according to claim 1 , wherein the chlorinated vinyl chloride resin has a chlorine content of 63 to 69% by weight. 4. The chlorinated vinyl chloride resin composition for a window frame according to claim 1 , wherein the infrared reflective pigment has an infrared reflectance of 15% or higher. 5. The chlorinated vinyl chloride resin composition for a window frame according to claim 1 , comprising the infrared reflective pigment in an amount of 0.1 to 10.0 parts by weight per 100 parts by weight of the chlorinated vinyl chloride resin. 6. The chlorinated vinyl chloride resin composition for a window frame according to claim 1 , further comprising an impact resistance modifier. 7. The chlorinated vinyl chloride resin composition for a window frame according to claim 6 , wherein the impact resistance modifier is a styrene-conjugated diene copolymer or an acrylic copolymer. 8. The chlorinated vinyl chloride resin composition for a window frame according to claim 6 , comprising the impact resistance modifier in an amount of 4.0 to 12.0 parts by weight per 100 parts by weight of the chlorinated vinyl chloride resin. 9. The chlorinated vinyl chloride resin composition for a window frame according to claim 1 , further comprising a lubricant. 10. The chlorinated vinyl chloride resin composition for a window frame according to claim 9 , wherein the lubricant is at least one selected from the group consisting of an aliphatic hydrogen carbide lubricant, a higher fatty acid lubricant, an aliphatic alcohol lubricant, an aliphatic ester lubricant, and a metal soap lubricant. 11. The chlorinated vinyl chloride resin composition for a window frame according to claim 9 , comprising the lubricant in an amount of 2.0 to 6.0 parts by weight per 100 parts by weight of the chlorinated vinyl chloride resin. 12. A window frame member comprising a molded article of the chlorinated vinyl chloride resin composition for a window frame according to claim 1 .
