Abstract: A polyamide 6,6 resin composition having improved toughness, abrasion resistance and frictional resistance is provided herein. The polyamide 6,6 resin composition comprises a graft copolymer of polyethylene and maleic anhydride, layered nanoclay, and a nucleating agent with a predetermined composition ratio in a base resin of polyamide 6,6 having ultra high viscosity. The polyamide 6,6 resin composition has properties of tensile strength (ISO527) of 83 Mpa or greater, elongation at break (ISO527) of 30% or greater, a kinematic friction coefficient of steel to metal measured by a ring-on-ring friction and abrasion tester of 0.30 or less, and a specific abrasion amount of 0.020 mm3/Kgf·km or less. The resin composition is useful as a worm gear for a motor-driven power steering device.

Abstract: The present invention relates to an easily-plated PC/ABS alloy and its preparation method. The PC/ABS alloy includes following components: 30-70 parts by weight (pbw) of PC resin, 15-65 pbw of ABS resin, 5-10 pbw of PEO resin, 0.1-1 pbw of antioxidant, and 0.1-1 pbw of lubricant. For preparation, blending the PC resin, ABS resin, PEO resin, antioxidant and lubricant in a mixer; and putting a mixture in a twin-screw extruder for granulation, thus producing easily-plated PC/ABS alloy. The method is simple and practicable. PEO resin makes PC/ABS surface have the property of hydrophilicity, which makes the etching solution easier to wet the surface when under etching, so that the etching becomes much easier. The binding force of hydrophilic group on the surface of PEO to the metal is strong. The binding force of PC/ABS alloy material is improved due to the combination between the chemical bond and physical force.
