摘要:
The present invention relates to a thermoplastic laminate for an eyewear, a decorative part comprising the thermoplastic laminate and a preparation process therefore. In particular, during the preparation of the laminate, a high frequency welding machine is used for bonding thermoplastic layers. The present invention uses a high frequency welding machine for the instant welding of the thermoplastic layers. Good bonding strength exists between different layers. Further, the patterns of the core layer are intact, and have high-definition images. The patterns are located in the core layer, not affected by external environmental factors, and not easily abraded. Further, multiple surfaces of the part for an eyewear have patterns, increasing the beautiful appearance of the part for an eyewear, and meeting the requirements of customers to the largest extent.
