High-toughness laser direct structuring glass fiber reinforced polyphenylene sulfide composite material and preparation method thereof

Abstract

The invention discloses a high-toughness laser direct structuring glass fiber reinforced polyphenylene sulfide composite material and a preparation method thereof, and belongs to the field of modified plastics. The high-toughness laser direct structuring glass fiber reinforced polyphenylene sulfide composite material is prepared from the following components in parts by weight: 40 to 60 parts of polyphenylene sulfide, 5 to 15 parts of phenolphthalein-based polyether ketone, 20 to 40 parts of glass fiber, 5 to 15 parts of mineral filler, 0.1 to 0.3 part of a high-temperature lubricating agent, 6 to 10 parts of a laser activating agent, 0.1 to 0.3 part of a metal deactivator and 0.2 to 1 part of a dispersing agent. The invention further discloses a preparation method. Compared with similar products, the high-toughness laser direct structuring glass fiber reinforced polyphenylene sulfide composite material disclosed by the invention has higher impact strength and flame retardant effect, a wide laser processing window and strong coating binding force.

Description

technical field [0001] The invention relates to the field of modified plastics, in particular to a glass fiber reinforced polyphenylene sulfide composite material with high toughness that can be directly formed by laser and a preparation method thereof. Background technique [0002] Laser direct structuring technology, also known as LDS (Laser Direct Structuring) technology, is a professional laser processing, injection and electroplating process production technology. Its principle is to endow ordinary plastic components / circuit boards with electrical interconnection functions and support components The function is integrated with the support, protection and other functions of the plastic shell, as well as the shielding and antenna functions produced by the combination of mechanical entities and conductive graphics. The biggest difference between LDS technology and ordinary electroplating metallization is that it uses an electroless chemical plating process. The bonding str...
