Technical field
The present invention relates to the engineering plastics field, be specifically related to a kind of modification that is used to prepare capacitor casing and gather the carbon ester material.
Background technology
Be used for the electrical condenser on the power vehicle at present, its shell shell adopts stainless steel or ABS engineering plastics to process usually.The former housing is heavy, and cost is high, is prone to get rusty, and very easily produces the housing puncture again and draws fiery phenomenon, is substituted by the ABS material just gradually.Though and the ABS material housing is in light weight, the wall thickness of the housing that this material is processed must be more than 5cm, and side resistance to deformation temperature is not low; Yielding, but when wall was too thick, difficulty of processing increased; Waste product is many during production, and qualification rate is low, has increased production cost; The ABS material is prone to suction simultaneously, causes the capacitor casing insulating property to reduce, and dielectric strength descends.
Summary of the invention
In order to overcome above-mentioned deficiency, the invention provides a kind of modification that is used to prepare capacitor casing and gather the carbon ester material, adopt this modification to gather the injection molded locomotive capacitor casing of carbon ester material and have good processability, not yielding and the big characteristics of dielectric strength.
The technical scheme that adopts for the present invention of realization above-mentioned purpose is following:
Be used to prepare the modified polycarbonate material of capacitor casing, it is characterized in that: the weight part of its constitutive material is following:
Polycarbonate 56-75 part, ABS resin 15-25 part, ABS-g-MAH compatilizer 2-4 part; Toughner MBS 3-8 part, fire retardant STB 3-4 part, organic silicon fibre retardant 3-4; Line style aliphatic category epoxy resin 0.1-0.5 part, propenoate 1-2 part, composite antioxidant B215 0.1-0.3 part.
The described modification that is used to prepare capacitor casing gathers the carbon ester material, and it is characterized in that: the weight part of its constitutive material is following:
70 parts of polycarbonate, 22 parts of ABS resins, 3 parts of ABS-g-MAH compatilizers, 5 parts of toughner MBS, 3 parts of fire retardant STB, organic silicon fibre retardant 4,0.4 part of line style aliphatic category epoxy resin, 1 part of propenoate, 0.3 part of composite antioxidant B215.
The described modification that is used to prepare capacitor casing gathers the preparation method of carbon ester material, it is characterized in that, specifically may further comprise the steps:
(1) takes by weighing each starting material respectively;
(2) starting material that take by weighing are mixed according to formula rate;
(3) compound is put into carried out drying in the drying machine, drying temperature is 75-85 ℃, and be 8-10 hour time of drying;
(4) drying is good batch mixing drops into twin screw extruder, and extruding pelletization, the barrel zone temperature of forcing machine are 210-270 ℃.
Beneficial effect of the present invention:
Modification of the present invention gathers the carbon ester material, has to have the dual characteristics that gathers carbon ester material and ABS material concurrently, adopts this modification to gather the injection molded locomotive capacitor casing of carbon ester material and has good processability, the not yielding and big characteristics of dielectric strength.
Embodiment
A kind of modification that is used to prepare capacitor casing gathers the carbon ester material, and the weight part of its constitutive material is following:
70 parts of polycarbonate, 22 parts of ABS resins, 3 parts of ABS-g-MAH compatilizers, 5 parts of toughner MBS, 3 parts of fire retardant STB, organic silicon fibre retardant 4,0.4 part of line style aliphatic category epoxy resin, 1 part of propenoate, 0.3 part of composite antioxidant B215.
The modification that is used to prepare capacitor casing gathers the preparation method of carbon ester material, specifically may further comprise the steps:
(1) takes by weighing each starting material respectively;
(2) starting material that take by weighing are mixed according to formula rate;
(3) compound is put into carried out drying in the drying machine, drying temperature is 80 ℃, and be 8 hours time of drying;
(4) drying is good batch mixing drops into twin screw extruder, and extruding pelletization, the barrel zone temperature of forcing machine are 210-270 ℃.
Experimental data
Modification of the present invention gathers the carbon ester material and the ABS properties of materials contrasts like following table:
| Performance | Modified polycarbonate of the present invention | ABS |
| Tensile strength | 68-75mPa | 40-55mPa |
| Bending strength | 97-122mPa | 30-65mPa |
| The notch shock toughness | 72-83KJ/m 2 | 15-35KJ/m 2 |
| Water-intake rate | 0.4-0.6% | 1.1% |
| Heat-drawn wire | 136-152 | 95 |
| Second-order transition temperature | 150 | 110 |
| Embrittlement temperature | -105-130 | -25 |
Can be found out that by last table the tensile strength of modified polycarbonate, bending strength, notch shock toughness all obviously are superior to the ABS material, heat-drawn wire and second-order transition temperature are higher than the ABS material, and water-intake rate is lower than the ABS material.
