Television Housing and Method for Manufacturing the Same
A television housing has a structure including a stainless steel (SUS) frame; and a plastic member in contact with at least one side of the stainless steel frame. The plastic member includes (A) a polycarbonate resin, (B) a rubber modified aromatic vinyl graft copolymer resin, and (C) a non-adhesive glass fiber. The plastic member can have excellent properties in terms of appearance, gloss, surface roughness, and stiffness. In addition, the plastic member can be highly dimensionally stable.
1 . A television housing having a structure comprising:
a stainless steel (SUS) frame; and
a plastic member in contact with at least one side of the stainless steel frame,
wherein the plastic member comprises (A) a polycarbonate resin, (B) a rubber modified aromatic vinyl graft copolymer resin, and (C) a non-adhesive glass fiber.
2 . The television housing according to claim 1 , wherein the plastic member is produced by a steam molding process.
3 . The television housing according to claim 1 , wherein the plastic member has a gloss of at least about 95, as measured in accordance with the method of ASTM D 2457, and a surface roughness (Ra) not greater than about 20 nm, as measured in accordance with the method of ASTM D 4417-B.
4 . The television housing according to claim 1 , wherein the difference in shrinkage between the stainless steel (SUS) frame and the plastic member is not greater than about 0.003 cm/cm, as measured in accordance with the method of ASTM C356.
5 . The television housing according to claim 1 , wherein the non-adhesive glass fiber (C) has an average length of about 2 to about 5 mm and an average diameter of about 10 to about 20 μm.
6 . The television housing according to claim 1 , wherein the non-adhesive glass fiber (C) is not exposed to the surface of the plastic member.
7 . The television housing according to claim 1 , wherein the plastic member further includes a flame retardant, impact-reinforcing agent, anti-drip agent, antibacterial agent, heat stabilizer, antioxidant, release agent, light stabilizer, inorganic additive, surfactant, plasticizer, lubricant, antistatic agent, colorant or a combination thereof.
8 . A method for manufacturing a television housing, comprising:
steam-molding (A) a polycarbonate resin, (B) a rubber modified aromatic vinyl graft copolymer resin, and (C) a non-adhesive glass fiber into a plastic member; and
bonding the plastic member to a stainless steel (SUS) frame.
9 . The method according to claim 8 , wherein the steam molding is performed by a rapid heat cycle molding (RHCM) process.
