Title:
POLYETHYLENE COMPOSITION, AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/067000
Kind Code:
A1
Abstract:
The present invention provides a polyethylene composition, and a preparation method therefor and use thereof, and belongs to the field of high polymer materials. The polyethylene composition comprises the following components in parts by weight: 60-99 parts of a high-density polyethylene resin, 1-40 parts of a polyester resin, 0.5-15 parts of an interface-regulating inducer, 0.5-3 parts of an infrared-transmitting enhancer, 0.1-2 parts of an organic toner, 0.1-2 parts of an antioxidant, and 0.1-2 parts of a lubricant. The prepared polyethylene composition can overcome the problem that the laser welding cannot be achieved due to the large difference in polarity and compatibility between dissimilar materials, and realize the laser welding of polyethylene and polyester materials. Meanwhile, the prepared polyethylene composition can have relatively high light transmittance as a light-transmitting layer for the laser welding, and can also achieve high welding strength with a light-absorbing layer.
