Problems solved by technology

The advantage of spinel copper compounds is that electroless plating is fast, but copper is a depolymerization agent for PC, which is easy to cause PC degradation. At the same time, most copper compounds are black and cannot be used as light-colored products.

Abstract

The invention relates to a resin capable of directly formed by laser and a preparation method thereof. The resin is prepared from the following raw materials in parts by weight: 93-97 parts of a matrix resin, 3-7 parts of a laser sensitive additive, and 0.1-0.9 part of other components. The preparation method comprises the following steps: weighting the raw materials in parts by weight: mixing the matrix resin, the laser sensitive additive and other components in a medium-speed mixer to mix for 20 minutes; and placing the obtained mixture into a twin-screw extruder, and then carrying out melting extrusion and granulating on the obtained product. Compared with the prior art, the resin disclosed by the invention mainly broadens the scope of laser sensitive additives which are no longer limited to spinel structured compounds, has small possibility of causing PC degradation, and can be prepared into various light-color products.

Description

technical field [0001] The invention relates to a laser direct forming resin and a preparation method thereof, which are widely used in the fields of antennas of mobile phones and notebook computers, and the like. Background technique [0002] Laser Direct Structuring, or Laser Direct Structuring, referred to as LDS, is a 3D-MID (Three-dimensional molded interconnect device) production technology that combines injection, laser processing and electroplating. Endow the electrical interconnection function, so that in addition to the functions of support and protection, the plastic shell and structural parts can be combined with the conductive circuit to produce shielding, antenna and other functions. To put it simply, on the injection-molded plastic bracket, the three-dimensional metal circuit is directly plated on the bracket by using laser technology, so that the plastic bracket has certain electrical properties. This technology can be applied to mobile phone antennas, autom...
