Abstract
The liquid crystal polyester composite material comprises the following components in parts by weight: 70 parts of liquid crystal polyester; 2-12 parts of a laser forming additive; the liquid crystal polyester is prepared from the following repetitive units in percentage by mole of a liquid crystal polyester chain segment: 0.5 to 30 mol percent of a p-hydroxybenzoic acid unit, 30 to 55 mol percent of a 2-hydroxy-6-naphthoic acid unit, 20 to 25 mol percent of a biphenol unit and 20 to 25 mol percent of a terephthalic acid unit; the average particle size of the laser forming additive is 5-25 microns. The laser forming additive with a specific average particle size range is added into the liquid crystal polyester with a specific structure, so that uniform distribution of the laser forming additive is realized, the laser etching chemical plating performance of the liquid crystal polyester composite material can be improved, and the liquid crystal polyester composite material has the advantage of low dielectric loss.
Description
technical field [0001] The invention relates to the technical field of polymer materials, in particular to a liquid crystal polyester composite material and a preparation method and application thereof. Background technique [0002] Laser Direct Structuring (LDS) or laser engraving plating refers to the use of computer-controlled laser beams to irradiate the laser beams to the workpiece, and the area irradiated by the laser beam has the ability to activate, and the workpiece has activation ability. Capable areas can deposit copper, nickel, gold and other metals in the electroless bath, and areas that have not been irradiated by the laser beam cannot deposit copper, nickel, gold and other metals, so that this resin composition has a choice in depositing metals sex. Compared with other traditional processes, LDS technology can fabricate three-dimensional circuits on plastic substrates, with greater design freedom, thereby saving space and meeting the requirements of lightweig...
