Acid esters system, free metal ion or atom are the catalyst that catalytic resin is degraded；Meanwhile, inorganic metal compound or have
Machine metal mixture is presented alkalescence to varying degrees, can also be further exacerbated by the degradation reaction degree of polycarbonate compound,
So that material loses practical value.Therefore, studied in the complex systems and solve laser direct forming additive to poly-
The influence of carbonic ester system thermodynamics and processing characteristics is the core and key issue for preparing the material.
For the concrete application of material, if the selection of laser direct forming additive is improper, injection may be caused
Surface produces the defects such as filamentary silver, pit after shaping, causes the slow not even plating of later stage chemical plating plating, and the test of hundred lattice can not
Pass through；Or mechanical performance declines substantially after chemical plating, it is impossible to meet the requirement of materials'use performance.

About 50% to about 60%, and operated under Standard processing conditions well known to those skilled in the art.After pellet is extruded,
Before test sample is moulded, in about 100 DEG C of dried granules.It is 260 DEG C to 280 DEG C between temperature song, and mold temperature dimension
Hold carries out molding process in the case of 80 DEG C.
Two kinds of different ratios of LDS additives are illustrated in table 1 to polycarbonate compound heat endurance, mechanical performance
With the influence of plating performance (or changing plating performance).
Here compound heat endurance is characterized with the change (MFR shift) of melt flow rate (MFR), its specific test-strips
Part is：At 300 DEG C, melt flow rate (MFR) is measured under the conditions of 1.2Kg, the sample residence time is respectively set as 6 minutes and 18 minutes,
Obtain the numerical value of MFR1 (6 minutes) and MFR2 (18 minutes).Correspondingly, MFR shift=(MFR2-MFR1)/MFR1*100；It is logical
Often think that this index can just meet real requirement less than 30.

For this index can just meet real requirement more than or equal to 9.
As it can be seen from table 1 in the case where LDS-1 (alkali formula cupric phosphate) is used alone, composite melt flow rate
Change highly significant, it is meant that polycarbonate matrix has obvious degraded, and material heat endurance is poor.The correspondingly breach of sample
Impact strength is relatively low.In the case where cupric LDS additives and stanniferous LDS additives are used cooperatively, complex systems it is molten
The change of body flow rate is significantly improved, while the notch impact strength and elongation at break of sample are also maintained at compared with Gao Shui
It is flat, show excellent toughness.In addition, all samples are respectively provided with excellent change plating performance in table.

From table 2 it can be seen that in the case where LDS-3 (zinc stannate) is used alone, the change of composite melt flow rate
Change smaller, it is meant that material has preferable heat endurance, but the change plating performance of sample can not meet functional need.In cupric LDS
In the case that additive and stanniferous LDS additives are used cooperatively, the variation in MFR of complex systems can be controlled
In relatively low level, while the notch impact strength and elongation at break of sample are higher, excellent toughness is shown.It is prior
