Title:
BULK MOLDING COMPOUND AND LED DISPLAY SCREEN USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/155815
Kind Code:
A1
Abstract:
A bulk molding compound, comprising the following components, in percentage by mass: 15%-20% of an unsaturated resin, 7%-10% of a low-shrinkage agent, 10%-15% of a diluted monomer, 0.2%-0.5% of an initiator, 0-0.05% of a thickening agent, 0-1.5% of an internal mold release agent, 0-0.05% of a polymerization inhibitor, 25%-30% of a flame retardant, 6%-10% of a fiber reinforcement, 25%-30% of a high-thermal-conductivity filler, and 0-1% of a pigment. Also provided is an LED display screen (1000) using the bulk molding compound as a bottom case (122). The bulk molding compound has low density, high thermal conductivity and high flame retardancy properties; and the bottom case (122) of the LED display screen made therefrom has a relatively light mass, so that the LED display screen (1000) can have higher flame retardancy while also being lightweight, and maintains a lower screen body temperature during use.
