Abstract

A polyphenylene sulfide resin composition which comprises 100 parts by weight of a polyphenylene sulfide resin (A) and, compounded therewith, 1 to 100 parts by weight of glass fibers (B) having a single-fiber diameter of 12 [mu]m or lager and has a crystallization temperature during cooling of 205 DEG C or lower. Also provided is a polyphenylene sulfide resin composition which comprises 100 parts by weight of a polyphenylene sulfide resin (A) and, compounded therewith, 1 to 100 parts by weight of glass fibers (B) having a single-fiber diameter of 10 to 12 [mu]m, excluding 12 [mu]m, has a crystallization temperature during cooling of 205 DEG C or lower and a chloroform-extractable content of 0.5 wt.% or lower, and gives a 2 mm-thick molding which has a transmittance of 15% or higher for laser light having a wavelength of 940 nm and a heat distortion temperature of 230 DEG C or higher under a load of 1.82 MPa.

Description

technical field [0001] The present invention relates to a polyphenylene sulfide resin composition, and more particularly, the present invention relates to a polyphenylene sulfide resin composition that is not resistant even when used as a molding on the laser light transmission side in a laser welding method. The degree of freedom in design of molded parts is reduced, and excellent laser weldability and heat resistance can be obtained. Background technique [0002] Polyphenylene sulfide resin has various characteristics such as excellent mechanical properties, heat resistance, chemical resistance, and thin-wall fluidity in a good balance, so it is widely used in fields such as electrical, electronic parts, and automotive parts. [0003] In the past, when the shape of the resin molded part was complex, it was first molded into a plurality of discrete parts, and then these parts were joined to form a single body, thereby obtaining a product with a complex shape. Such a method...
