Test methods

[0107] Melt volume flow rate (MVR) was determined according to ISO 1133:2012-03 at a test temperature of 300° C., mass 1.2 kg using a Zwick 4106 instrument from Zwick Roell. The abbreviation MVR stands for the starting melt volume flow rate (after 4 minutes preheating time), and the abbreviation IMVR stands for melt volume flow rate after 19 min.

[0108] Shear viscosity (melt viscosity) at 300° C. was determined according to ISO 11443:2014-04 using a Gottfert Visco-Robo 45.00 instrument.

[0109] Charpy impact strength was measured according to ISO 179/1eU:2010 on single-side injected test bars measuring 80 mm×10 mm×4 mm at 23° C.

[0110] The Vicat softening point VST/B50 as a measure of heat resistance was determined according to ISO 306:2013 on test specimens measuring 80 mm×10 mm×4 mm with a 50 N piston load and a heating rate of 50° C./h with a Coesfeld Eco 2920 instrument from Coesfeld Materialtest.

[0111] Thermal conductivity was determined on injection-molded test specimens measuring 60×60×2 mm.sup.3 according to ASTM E 1461 (Nano Flash method).

[0112] Fire behavior was measured according to UL 94V on bars measuring 127 mm×12.7 mmדmm reported in the table”.

[0113] The ULSV test was performed on sheets measuring 150 mm×105 mm×2.0 mm.

Production of the Compositions

[0114] Production of the molding materials was carried out by melt mixing/melt compounding in a twin-screw extruder/a co-kneader at a melt temperature of 260-310° C. Melt mixing was particularly preferably carried out using a co-kneader and the temperature of the melt was limited to not more than 300° C.

[0115] The components B were only later added to the components A and C previously melted or dispersed in the melt. Addition of C was carried out simultaneously with or immediately after the melting of component A. The components FR, D and E were added at any desired juncture. The addition of FR and E was preferably carried out simultaneously with or immediately after the addition of C. The addition of components D was preferably carried out before or simultaneously with the addition of B. The test specimens were in each case produced by injection molding at a melt temperature of 280° C.-300° C. and a mold temperature of 85° C.-95° C.

Results

[0116] The results obtained from inventive compositions and comparative examples are recited hereinbelow.

[0117] The comparative examples V1 to V10 show that customary flame retardant combinations of FR1-FR4 in a formulation described in WO 2018/037037 provide insufficient flame retardancy: both the UL94V test at 1.5-1.0 mm and the UL94 5V test at 2.0 mm are failed. This also applies when a polycarbonate having a higher average molecular weight (A2) is employed (V2, V4, V6, V8, V10).

[0118] Reducing the amount of B1 to 25% by weight makes it possible to pass the UL94V test at 1.5 mm provided that 0.8% FR1 and 0.2% FR2 are employed (V11). However, a 5VA score in the UL94 5V test at 2.0 mm (V11) is not achieved.

[0119] This can only be achieved by addition of an appropriate amount of D2 (1, 2, 3, 4), wherein 2.5% of component D2 are not yet sufficient to achieve a reliable 5VA score (V12). The total amount of fillers (sum of components B and D) in examples 1, 2 and 4 is equal to or exceeds the amount of filler in V1 to V10.

[0120] Compared to the addition of D2 the addition of D3 does not result in an improvement in the results of the UL94 5V test (V13, V14, V15). Combinations of D2 and D3 likewise do not result in an improvement in the result of the UL94 5V test (V20, V21).

[0121] Likewise, the addition of component D1 does not have a positive effect on the result of the UL94 5V test (V16, V17, V18, V19). The combination of D1 and D2 does not result in an improvement in the result of the UL94 5V test (V22) either.

[0122] Examples 2 and 4 show that a greater amount of white pigment E1 in the formulation is permissible without losing essential properties of the molding material.

[0123] Copolycarbonates such as for example a copolycarbonate of bisphenol-A and 4,4′-dihydroxybiphenyl (DOD) can also be correspondingly flame retarded with the inventive combination of FR1, FR2 and D2 (example 5).

[0124] When the total filler amount (sum of components B and D) is further increased such as in V27, the addition of 0.8% FR1 and 0.2% FR2 is no longer sufficient to achieve a VO score in the UL94V test at 1.5 mm and a 5VA score in the UL94 5V test at 2.0 mm.

[0125] In this case it is preferable to add a phosphorus-containing flame retardant such as FR5 and/or FR6 instead of FR2.

[0126] Examples V23, V24 and V29 show that sole use of FR1 and FR5 in high concentrations in the absence of component D2 does not allow a 5VA score in the UL94 5V test at 2.0 mm to be achieved. Furthermore, addition of more than 7% of FR5 causes the heat resistance of the molding materials measured by Vicat softening temperature VST/B50 according to ISO 306 to fall so severely that the molding materials are no longer suitable for usage temperatures above 115° C. (V23, V24 versus V29).

[0127] A V0 score in the UL94V test at 1.5 mm and a 5VA score in the UL94 5V test at 2.0 mm are only achieved when the amount of FR5 is reduced to less than 7% and component D2 is also added (example 6).

[0128] An excessively large amount of FR5 again has a negative effect on the heat resistance of the molding materials, the results of the Charpy impact test according to ISO 179/1eU and the result of the UL94 5V test (V28).

[0129] Particularly good combinations of properties are achievable when a combination of FR1 and FR6 with component D2 is used for flame retardancy (examples 7 and 8). The heat resistance (VST/B50 according to ISO 306) in the examples is above 115° C. and a V0 score in the UL94V test at 1.5, 1.2 and even 1.0 mm as well as a 5VA score in the UL94 5V test at 2.0 mm are reliably achieved. In addition, the result of the Charpy impact test according to ISO 179/1eU is above 20 kJ/m.sup.2 which represents an exceptional result for molding materials having such a total filter content.

[0130] Examples 8 and V30 show that the addition of component D2 is necessary to achieve the 5VA score in the UL94 5V test at 2.0 mm.
