Problems solved by technology

Use CuCr 2 o 4 A disadvantage of spinel as an LDS additive is that CuCr 2 o 4 Spinel is detrimental to the mechanical properties of the matrix polymer
thus limiting the applications of the resulting polymers
On the other hand, it has been observed that spinel (such as NiFe 2 o 4 ) cannot be plated at all and also impairs the mechanical properties

Embodiment 1

[0084] According to standard DSM Stanyl ForTii TMCompounding condition, make 65wt.% Stanyl ForTii TM DS100, 30 wt.% glass fibers and 5 wt.% additives were compounded in a ZE25 twin-screw extruder from KrausMaffei Berstorff. After extrusion, the obtained compound material is cut into pellets for injection molding. In an injection molding process, these granules were formed into plates of size 80x80x2 mm. The injection molded plates were then put into a Trumph Laser Mark Machine with the parameter settings shown in Table 1. The type of laser we use is a Nd:YAG laser with a wavelength of 1064nm.

[0085] Increase the temperature of the plating bath to 48°C and maintain the temperature at 48°C. After laser treatment, the laser treated panels were completely immersed in the copper electroless plating bath for 30 minutes. Before and after plating, the panels were rinsed with deionized water.

[0086] Table 1 shows the parameter settings of the laser machine used in Example 1 a...

[0092] mechanical properties

[0093] Will contain 65wt.% Stanyl ForTii TM Pellets of DS100, 30 wt.% glass fiber and 5 wt.% LDS additive were injection molded into standard bars for tensile test ISO 527 and Charpy test ISO 179, and the results are shown in Table 2.

[0096] in conclusion

[0097] According to the data shown in Table 2, with CuCr 2 o 4 The mechanical properties (such as elongation at break and strength) of compositions comprising 25Ni / 75Zn are greatly improved compared to other compositions comprising Ni and / or Zn ferrites.

Abstract

Present application discloses a thermoplastic composition comprising a) 42.5 wt.% to 94 wt.% of thermoplastic matriXresin; b) 1 wt.% to 7.5 wt.% of a laser direct structuring additive; and c) 5 wt.% to 50 wt.% fibrous reinforcement agent; wherein the wt.% is relative to the total weight of the composition; wherein the laser direct structuring additive is represented by formula ZnxNi(1-x)Fe2O4, wherein the Xis higher than 0.60 and lower than 0.85; wherein the composition is capable of being plated after being activated using a laser.

Description

technical field [0001] The present invention relates to thermoplastic polymer compositions comprising laser direct structuring (LDS) additives. In particular, the present invention relates to articles prepared by the LDS process and methods for their preparation. Background technique [0002] Laser Direct Structuring (LDS) is a process that enables injection molded articles to be selectively plated with metal to form discrete conductive circuit paths. First, a plastic article is injection molded using a polymer compound / composite specially formulated for the process. The article is then activated using a laser in the desired pattern, thereby activating the surface of the article in the areas traced with the laser. The article is then subjected to an electroless plating process using a metal such as copper, nickel or gold; the resulting circuit pathways exactly follow the laser pattern. [0003] An advantage of the Laser Direct Structuring (LDS) process is the ability to o...
