Abstract

[Problem to be Solved] There is provided automotive lamp peripheral parts excellent in the heat resistance, rigidity and fogging property. [Solution] The automotive lamp peripheral part according to the present invention is obtained from a resin composition containing 70% by mass or more of a polyphenylene ether (A), and has a haze value of a glass plate of 1.0% or less after the glass plate is subjected to a following fogging test using an apparatus according to ISO 6452: <Fogging Test> 60 g of a pellet or a molded article obtained from the resin composition is put in a glass-made sample bottle; the sample bottle is covered with a glass plate as a lid, and heated at 170° C. for 24 hours to thereby generate fogging on the glass plate.

Claims

exact text as granted — not AI-modified
1 . An automotive lamp peripheral part, being obtained from a resin composition comprising 70 to 95% by mass of a polyphenylene ether (A) and 5 to 25% by mass of a kaolin clay (E) having an average primary particle diameter of 0.01 to 1.0 μm; and
 having a haze value of a glass plate of 1.0% or less after the glass plate is subjected to a following fogging test using an apparatus according to ISO 6452: 
 <Fogging Test> 
 60 g of a pellet or a molded article obtained from the resin composition is put in a glass-made sample bottle; the sample bottle is covered with a glass plate as a lid, and heated at 170° C. for 24 hours to thereby generate fogging on the glass plate. 
 
     
     
         2 . The automotive lamp peripheral part according to  claim 1 , wherein the resin composition further comprises 1 to 25% by mass of a styrene-based resin (B). 
     
     
         3 . The automotive lamp peripheral part according to  claim 2 , wherein the styrene-based resin (B) is a styrene-based resin reinforced with no rubber. 
     
     
         4 . The automotive lamp peripheral part according to  claim 1 , wherein the resin composition further comprises 0.1 to 10% by mass of a styrene-based thermoplastic elastomer (C). 
     
     
         5 . The automotive lamp peripheral part according to  claim 4 , wherein the styrene-based thermoplastic elastomer (C) is a styrene-based thermoplastic elastomer functionalized with a compound having an amino group. 
     
     
         6 . The automotive lamp peripheral part according to  claim 1 , wherein the resin composition further comprises 0.1 to 7% by mass of an alkanesulfonic acid metal salt (D). 
     
     
         7 . The automotive lamp peripheral part according to  claim 1 , wherein the kaolin clay (E) has an average primary particle diameter of 0.01 to 0.5 μm. 
     
     
         8 . The automotive lamp peripheral part according to  claim 1 , wherein a proportion of a number of agglomerated particles of the kaolin clay (E) having a particle diameter of 2 μm or more accounts for less than 1%. 
     
     
         9 . The automotive lamp peripheral part according to  claim 1 , wherein the kaolin clay (E) is a waterwashed kaolin clay. 
     
     
         10 . The automotive lamp peripheral part according to  claim 1 , wherein the kaolin clay (E) is a kaolin clay dried by using a drier. 
     
     
         11 . The automotive lamp peripheral part according to  claim 1 , wherein the kaolin clay (E) is a kaolin clay dried by using a vacuum drier heated at an interior temperature thereof of 150 to 200° C. 
     
     
         12 . The automotive lamp peripheral part according to  claim 1 , wherein the kaolin clay (E) has a residual volatile content (a weight loss proportion after drying at 200° C. for 3 hours by a vacuum drier) of 0.5% by mass or less. 
     
     
         13 . The automotive lamp peripheral part according to  claim 1 , wherein the kaolin clay (E) is a kaolin clay surface treated with a silane compound. 
     
     
         14 . The automotive lamp peripheral part according to  claim 1 , wherein the kaolin clay (E) is a kaolin clay surface treated with a sulfur-based silane compound. 
     
     
         15 . The automotive lamp peripheral part according to  claim 1 , wherein the polyphenylene ether (A) has a reduced viscosity (measured at 30° C. using a chloroform solvent) of 0.25 to 0.43 dL/g. 
     
     
         16 . The automotive lamp peripheral part according to  claim 1 , wherein an aluminum-deposited specular portion has a total reflectance of 85% or more; and the aluminum-deposited specular portion has a diffusion reflectance of 3.0% or less. 
     
     
         17 . The automotive lamp peripheral part according to  claim 1 , wherein the automotive lamp peripheral part is one selected from the group consisting of an automotive lamp lens holder, an automotive lamp extension and an automotive lamp reflector.
