Flame retardant ratings were derived based on the burn rate, extinguishing time, ability to resist dripping, and whether dripping (drip) was burning. Samples used for the test: bars having dimensions of 125mm length x 13mm width x no greater than 13mm thickness, the thickness of the bars when tested according to the invention being selected to be 1.5 mm. According to the UL94 protocol, and based on the test results obtained for five samples, the material flame retardant rating can be classified as (UL 94-HB): v0, V1, V2, 5VA and/or 5 VB; in the present invention, however, only the flame retardant rating of the material is classified as: v0, V1 and V2, and the classification criteria for each flame retardant rating are:
v0: in a sample placed so that its long axis is 180 degrees with respect to the flame, the period of burning and/or smoldering does not exceed 10 seconds after the ignition flame is removed, and the vertically placed sample does not produce dripping of combustion particles that ignite cotton wool. The flame holding time for the fifth bar is the flame holding time for the five bars, each lit twice, wherein the sum of the flame holding time for the first light (t1) and the flame holding time for the second light (t2), i.e. the maximum flame holding time (t1+ t2), is less than or equal to 50 seconds.
V1: in a sample placed so that its long axis is 180 degrees relative to the flame, the period of burning and/or smoldering does not exceed 30 seconds after the ignition flame is removed, and the vertically placed sample does not produce dripping of burning particles that ignite cotton wool. The flame holding time for the fifth bar is the flame holding time for the five bars, each lit twice, wherein the sum of the first lit flame holding time (t1) and the second lit flame holding time (t2), i.e. the maximum flame holding time (t1+ t2), is less than or equal to 250 seconds.
V2: in a sample placed so that its long axis is 180 degrees relative to the flame, the average period of burning and/or smoldering after removal of the ignition flame does not exceed 30 seconds, but a vertically placed sample produces dripping of burning particles that ignite cotton. The flame holding time for the fifth bar is the flame holding time for the five bars, each lit twice, wherein the sum of the first lit flame holding time (t1) and the second lit flame holding time (t2), i.e. the maximum flame holding time (t1+ t2), is less than or equal to 250 seconds.

Different from comparative examples 1 to 3, the high heat-resistant high-toughness polycarbonate composition prepared in the embodiment of the invention has excellent toughness and heat resistance while having excellent flame retardant rating, and particularly, the embodiment of the invention does not improve the flame retardant rating of the polycarbonate composition by adding a flame retardant in a raw material formula, and the principle of improving the flame retardant rating of the polycarbonate composition obtained in the invention is essentially different from that of comparative examples 1 to 3.
The polycarbonate composition prepared by the invention has advantages in toughness, heat resistance and flame retardant grade, and is mainly benefited from the optimization and improvement of raw material formula, which is specifically represented as follows: according to the invention, the phosphate homopolymer is added into the raw material formula, and on one hand, the phosphate homopolymer can well overcome the defect that the thermal deformation temperature and the toughness of polycarbonate are greatly reduced due to the addition of an organic phosphate flame retardant in the prior art, and the heat resistance and the toughness of the polycarbonate composition are effectively improved; on the other hand, the phosphate homopolymer also has a good flame retardant effect, and the flame retardant grade of the polycarbonate composition can be effectively improved; in addition, the phosphate homopolymer has excellent compatibility with polycarbonate, does not have a plasticizing effect on alloy, can obviously improve the heat resistance of the polycarbonate composition under the condition of not influencing the flame-retardant grade and the toughness of the polycarbonate composition, and is particularly suitable for occasions with higher requirements on use environments.
