(1) measuring method of melt flow rate (MFR) (MFR).Allow plastic pellet within certain time (10 minutes), certain temperature And (a variety of materials standard is different) are melted into plastic liquid under pressure, then measurement is flowed out by a diameter by 2.1mm round tube Grams.The grams value of outflow is bigger, indicates that the processing fluidity of the plastic material is better, on the contrary then poorer;It is used herein Testing standard is ISO 1133, unit: g/10min.Using test condition are as follows: the melt flows under 300 DEG C, 1.2kg load Rate (MFR).
(2) it the measuring method of cantilever beam impact strength: is measured and is lacked using the molding notched Chalpy impact stick of 4.0mm thickness Mouth cantilever beam impact strength.Notched Chalpy impact intensity is measured according to ISO 180, is recorded with kJ/m2 as a result, testing in room It is carried out under warm (23 DEG C).
(3) measuring method of UL94 anti-flammability:
According to " the flammable test of plastic material, the regulation of UL94 " carry out flammable test.Based on burn rate, put out Go out the time, resist drippage ability and fall drop (drip) whether just burning, to obtain flame retardant rating.Sample for test Product: having a size of 125mm length × 13mm width × it is not more than the stick of 13mm thickness, the thickness of present invention stick when testing It is selected as 1.0mm.It, can be by material flame retardant rating according to the UL94 regulation, and based on the test result obtained for five samples It is classified as (UL94-HB): V0, V1, V2,5VA and/or 5VB;But in the present invention, only the flame retardant rating of material is classified are as follows: V0, V1 and V2, and the classification standard of each flame retardant rating are as follows:
V0: it is placing so that in the sample that its long axis is 180 degree relative to flame, after flame is lighted in removing, is burning And/or the period smouldered is no more than 10 seconds, and the sample being disposed vertically does not generate the drop of the burning particles for the absorbent cotton that ignites It falls.The flame out time of 5th stick is the flame out time of five sticks, is each lighted twice, wherein the first flame out time lighted (t1) it is less than or equal to 50 seconds with the second summation (as maximum flame out time (t1+t2)) of flame out time (t2) for lighting.
V1: it is placing so that in the sample that its long axis is 180 degree relative to flame, after flame is lighted in removing, is burning And/or the period smouldered is no more than 30 seconds, and the sample being disposed vertically does not generate the drop of the burning particles for the absorbent cotton that ignites It falls.The flame out time of 5th stick is the flame out time of five sticks, is each lighted twice, wherein the first flame out time lighted (t1) it is less than or equal to 250 seconds with the second summation (as maximum flame out time (t1+t2)) of flame out time (t2) for lighting.
V2: it is placing so that in the sample that its long axis is 180 degree relative to flame, after flame is lighted in removing, is burning And/or the Average Life smouldered is no more than 30 seconds, but the sample being disposed vertically generates the drippage of the burning particles for cotton of igniting. The flame out time of 5th stick is the flame out time of five sticks, is each lighted twice, wherein the first flame out time lighted (t1) it is less than or equal to 250 seconds with the second summation (as maximum flame out time (t1+t2)) of flame out time (t2) for lighting.
(4) it the measuring method of heat deflection temperature (HDT): is used under 1.82MPa load according to testing standard ISO 75 The stick of 4.0mm thickness lays flat measurement HDT, with a DEG C record result.
Above-mentioned test result is referring to table 1.
The specific dosage of table 1 (unit: parts by weight) and the performance test results
As can be seen that comparative example 1-5 is made compared with specific embodiment 1-3 composite material obtained by the comparative example 1-5 The high or low variation of the ISO notch impact strength and flame retardant property of the polycarbonate compositions obtained, cannot meet height simultaneously Toughness and the fire-retardant requirement of thin-walled.Different from comparative example 1-5, the fire-retardant poly- carbon of high heat resistance thin-walled obtained by the embodiment of the present invention Polycarbonate greatly improved after organic metal sulfonate salt flame and nanometer wollastonite synergistic flame retardant in acid ester composite The flame retardant property of resin can accomplish the V-0 fire-retardant rank of 1.0mm thickness, and influence on the mechanical property of resin and heat resistance It is smaller, and since the selectivity of organic silicon rubber graft is added, the toughness of material is greatly improved, while to material Flame retardant property also has little effect.
High heat resistance thin-walled flame retardant polycarbonate composition product obtained by the present invention can be widely applied to such as household electric Device, switch on wall, kitchen appliance, house material, automotive material and component manufacture material of other industrial circles etc..
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
