  • Patent number: 10968344
    Abstract: The present disclosure provides a polyester composition suitable for ultrasonic welding and preparation method thereof, the composition includes the following components in parts by weight: 30˜50 parts of poly(1,4-cyclohexylene dimethylene terephthalate), 40˜60 parts of ABS, 5˜10 parts of a melt enhancer, 0.1˜1 parts of an antioxidant, and 0.1˜1 parts of a lubricant. Compared with the existing technologies, the polyester composition provided by the present disclosure improves melt strength by using the melt enhancer. The melt enhancer used is an ultra-high density polyethylene resin having a glycidyl methacrylate group after an irradiation treatment, so that the compatibility of the melt enhancer to the poly(1,4-cyclohexylene dimethylene terephthalate) is improved. In addition, by controlling a glass-transition temperature of the composition, no chipping is generated during ultrasonic welding, and the composition has a high welding strength, which is suitable for ultrasonic welding.

  • Patent number: 9834674
    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.
