Abstract
A disclosed composite material used for cellphone shells comprises the following compositions in parts by weight: 55-70 parts of PC (polycarbonate), 5-15 parts of ABS, 1-10 parts of a stress-cracking-resistant agent, 1-5 parts of a flexibilizer, 0.1-0.5 part of an anti-oxidant, 2-15 parts of a fire retardant, and 0.1-0.5 part of a toner. On the basis of not large change on mechanical properties of PC, the impact strength of the composite material is improved, the application field is expanded, and the application cost of the composite material is reduced.
Description
Technical field
The present invention relates to a kind of matrix material for phone housing, belong to technical field of polymer materials.
Background technology
PC (polycarbonate) has excellent shock resistance, creep resistance, dimensional stability and electric insulating quality, a kind of engineering plastics of superior performance, be widely used in the fields such as mechanical means, electronic product, automobile making, but also there is poor fluidity, easily stress cracking, the easily aging and shortcoming such as to wear no resistance, its application is in a lot of fields restricted.But, the shell of existing electronic product through be everlasting maintenance dismounting time fracture, be obviously that meanwhile, cost is relatively high because its shock strength index can not meet its needs as electronic product casing.
Summary of the invention
For solving the deficiencies in the prior art, the object of the invention is to the defect overcoming prior art, a kind of impact-resistant matrix material for phone housing is provided.
In order to realize above-mentioned target, the present invention adopts following technical scheme: a kind of matrix material for phone housing, is characterized in that, comprises following component and the parts by weight of each component are:
PC 55-70 part;
ABS 5-15 part;
Anti-stress cracking agent 1-10 part;
Toughner 1-5 part;
Oxidation inhibitor 0.1-0.5 part;
Fire retardant 2-15 part;
Toner 0.1-0.5 part.
Aforesaid a kind of matrix material for phone housing, is characterized in that, described anti-stress cracking agent is ethyl-hydrogenated nitrile-CALCIUM ACRYLATE terpolymer grafts or acrylic acid-grafted polyolefin elastic precursor copolymer.
Aforesaid a kind of matrix material for phone housing, is characterized in that, described PC is aromatic copolycarbonate.
Aforesaid a kind of matrix material for phone housing, is characterized in that, described toughner is at least one in POE, ethylene-butylene copolymer, ethylene propylene copolymer and this ethylene butadiene copolymers.
Aforesaid a kind of matrix material for phone housing, is characterized in that, described oxidation inhibitor is the one in antioxidant 1010, irgasfos 168, oxidation inhibitor 2921.
Aforesaid a kind of matrix material for phone housing, is characterized in that, described fire retardant is halogen-free inorganic flame retardant, can be the one in phosphorus system, phosphorus-nitrogen system, phosphorus-silicon system.
Beneficial effect of the present invention is: the present invention is changing on little basis the mechanical property of PC, improves its shock strength, expands Application Areas, and reduces its application cost.
embodiment:
Below in conjunction with specific embodiment, the present invention is described further.
The proportioning of each component of table 1 embodiment 1-4 and comparative example
Wherein, described anti-stress cracking agent is ethyl-hydrogenated nitrile-CALCIUM ACRYLATE terpolymer grafts or acrylic acid-grafted polyolefin elastic precursor copolymer.
Described PC is aromatic copolycarbonate.
Described toughner is at least one in POE, ethylene-butylene copolymer, ethylene propylene copolymer and this ethylene butadiene copolymers.
Described oxidation inhibitor is the one in antioxidant 1010, irgasfos 168, oxidation inhibitor 2921.
Described fire retardant is halogen-free inorganic flame retardant, can be the one in phosphorus system, phosphorus-nitrogen system, phosphorus-silicon system.
The performance test results of each embodiment of table 2 and comparative example
| Embodiment 1 | Embodiment 2 | Embodiment 3 | Embodiment 4 | Comparative example | |
| Tensile strength (Mpa) | 58 | 59 | 65 | 60 | 50 |
| Elongation at break (%) | 47 | 42 | 45 | 49 | 39 |
| Flexural strength (Mpa) | 97 | 94 | 95 | 99 | 81 |
| Modulus in flexure (Mpa) | 2655 | 2580 | 2601 | 2549 | 2501 |
| Notched Izod impact strength (kJ/m 2) | 34 | 35 | 38 | 39 | 20 |
Note: reference standard is: GB13525/T-92 and UL94.
As can be seen from Table 2, from notched Izod impact strength, the notched Izod impact strength of embodiment 1-4 is relatively better.For other indexs, embodiment 1-4 also has advantage, and associative list 1 can draw, due to adding of anti-stress cracking agent, its notched Izod impact strength be improved significantly.
More than show and describe ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
