Problems solved by technology

[0005] Korean Publication Patent No. 10-2012-0066197 and Korean Publication Patent No. 10-2012-0065547 respectively disclose four-component copolymerization of acrylic rubber-styrene monomer-butadiene rubber-vinyl cyano monomer quaternary block composed of high dispersion styrene-vinyl cyano copolymer and N-substituted maleimide monomer-α-alkylstyrene-unsaturated nitrile monomer Resin composition of shape copolymer, thereby trying to solve the environmental problems caused by the existing polyvinyl chloride resin, however, it is difficult to ensure the desired physical properties due to the decrease in dimensional stability and the decrease in impact strength due to inorganic substances
[0006] Also, Korean Laid-Open Patent No. 10-2006-0136567 discloses polycarbonate resin, methyl methacrylate-butadiene copolymer resin (ABS type) and styrene-vinyl cyano-based copolymer resin (SAN ) composition, thereby trying to improve the molding processability of existing polycarbonate resins, however, it was difficult to ensure the required dimensional stability because the coefficient of linear expansion was still high

Embodiment 1～4

[0113] According to an embodiment of the present invention, a phenolic antioxidant, thermal The stabilizer is fully mixed in a mixer, extruded by a twin-screw extruder with L / D = 35 and Φ = 45 mm, and the extruded product is made into pellets.

[0114] The produced pellets were dried at 90° C. for more than 5 hours before injection molding. Samples for measurement of physical properties were produced with a 10 oz injection molding machine at an injection temperature of 250°C. And, a door and window material sample was prepared with a PVC extruder under the extrusion conditions of Table 1 above.

Abstract

One embodiment of the present invention provides a resin composition for door and window materials containing polycarbonate resin, based on the total weight of the resin composition for door and window materials, the resin composition for door and window materials comprises: 40 to 95% by weight polycarbonate resin; 1-50% by weight of acrylic rubber-styrene monomer-vinyl cyano monomer copolymer resin; and 1-30% by weight of a weight-average molecular weight (Mw) of 1,000,000- 3,000,000 ultra-high molecular weight copolymer resin of styrene-based monomer-vinyl cyano-based monomer.

Description

[0001] CROSS REFERENCE TO RELATED APPLICATIONS This application claims priority from Korean Patent Application No. 10-2013-0119421 filed on Oct. 7, 2013, the entire contents of which are hereby incorporated by reference. technical field [0002] The invention relates to a resin composition for door and window materials containing polycarbonate resin, more specifically, to a poly Resin composition for door and window materials of carbonate resin. Background technique [0003] Polyvinyl chloride (PVC) resin is widely used in door and window materials, one of building materials. But, described polyvinyl chloride resin can produce a large amount of dioxins and other harmful substances to the environment when extruding or in the time of fire, as cadmium stearate (Cd-st) or lead stearate (Cd-st) of heat stabilizer ( Heavy metal ions contained in Pb-st) and the like act as human hormone disruptors, so they are included in the scope of regulation and become the main cause of proble...
