POLYESTER COMPOSITION SUITABLE FOR ULTRASONIC WELDING AND PREPARATION METHOD THEREOF
20200140675 · 2020-05-07 ·

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: 3050 parts of poly(1,4-cyclohexylene dimethylene terephthalate), 4060 parts of ABS, 510 parts of a melt enhancer, 0.11 parts of an antioxidant, and 0.11 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.
