Title:
POLYESTER COMPOSITION SUITABLE FOR ULTRASONIC WELDING AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/120008
Kind Code:
A1
Abstract:
The present invention provides a polyester composition suitable for ultrasonic welding and a preparation method therefor. The composition comprises 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 melt enhancer, 0.1-1 part of antioxidant, and 0.1-1 part of lubricant. Compared with the prior art, the polyester composition provided by the present invention improves melt strength by using the melt enhancer. The melt enhancer used is ultra-high density polyethylene resin having a glycidyl methacrylate group upon irradiation, so that the compatibility of the melt enhancer to the poly(1,4-cyclohexylene dimethylene terephthalate) is improved. In addition, by controlling the glass-transition temperature of the composition, no chipping is generated during ultrasonic welding, and the composition has high welding strength and is suitable for ultrasonic welding.
