Abstract
The present invention provides the sheathing material and preparation method thereof of a kind of electronic equipment.The sheathing material is made of the raw material components of following parts by weight：30 70 parts of polyphenylene oxide, 40 70 parts of high impact polystyrene, 10 15 parts of fire retardant, 35 parts of antioxidant, 13 parts of lubricant, 12 parts of carbon black toner；Wherein, the fire retardant is selected from one or more in triphenyl phosphate, bisphenol-A bis- (diphenyl phosphoesters), decabromodiphenylethane, antimony oxide and brominated triazine.It after each raw material component is stirred and evenly mixed, is placed in extruder and is squeezed out, squeeze out postcooling, pelletizing, drying, obtain the sheathing material.The sheathing material processing temperature in the preparation of the present invention is low, is easy to be molded, and sheathing material light weight obtained, shrinking percentage be low, temperature tolerance and anti-flammability are good, has wide range of applications.
Description
Technical field
The present invention relates to a kind of sheathing materials, and in particular to sheathing material of a kind of electronic equipment and preparation method thereof.
Background technology
The sheathing material of electronic equipment is usually acrylonitrile-butadiene-styrene (ABS) plastics (ABS), ABS engineering plastics (PC+
ABS), high impact polystyrene (HIPS) etc., the dimensional stability of the materials such as ABS, PC+ABS, impact resistance, processing fluidity
It is excellent, however density is in 1.15g/cm3More than, quality weight, and it is of high cost.HIPS is by the addition in polystyrene (PS)
Butylbenzene or butadiene rubber are modified, at low cost, easily molded processing, however the poor fire of the material and shrinking percentage height,
Using the electronic equipment casing of its preparation, deflection increases in reliability test, environmental test, not only influences electronic equipment
Appearance, or even be also possible to shell can be caused to crack, therefore be restricted using with application range.
Polyphenylene oxide (PPO) is a kind of thermoplastic engineering plastic haveing excellent performance, and density is small, thermal stability is high, however by
It is larger in molecule chain rigidity, therefore melt viscosity is high, poor fluidity, forming temperature is generally up to 280-330 DEG C, and processing and forming is tired
It is difficult；In addition, the defects such as stress cracking, notch impact strength be low occur there is also poor solvent resistance, easily for the material.In order to overcome
Itself and HIPS materials are usually carried out alloying by the drawbacks described above present in PPO materials, and being formed by alloy material can not only protect
The original characteristic of PPO materials is stayed, and processing performance greatly improves.
Although the forming temperature of PPO/HIPS alloy materials decreases compared with PPO materials, forming temperature is still up to
260-285 DEG C, such as further improves its processing performance to adapt to large scale, thin-walled or complicated product demand, then need to increase
Add the content of HIPS in alloy material, however this can lead to the decline of alloy material flame retardant property, mechanical performance etc., therefore how
Obtain that forming temperature is low, processing performance and comprehensive performance are good, especially while with good temperature tolerance and anti-flammability, low
Shrinking percentage and light sheathing material become urgent problem to be solved.
Invention content
The present invention provides the sheathing material and preparation method thereof of a kind of electronic equipment, for solving shell in the prior art
The technological deficiencies such as quality of materials weight, shrinking percentage height, temperature tolerance and poor fire.
The present invention provides the sheathing material of a kind of electronic equipment, is made of the raw material components of following parts by weight：Polyphenylene oxide 30-
70 parts, 40-70 parts of high impact polystyrene, 10-15 parts of fire retardant, 3-5 parts of antioxidant, 1-3 parts of lubricant, carbon black toner 1-2
Part；Wherein, the fire retardant is selected from triphenyl phosphate (TPP), bisphenol-A-bis- (diphenyl phosphoesters) (BDP), decabrominated dipheny second
It is one or more in alkane (DBDPE), antimony oxide and brominated triazine.
The present invention is by adding the resistance of specified weight part in the polyphenylene oxide and high impact polystyrene that are matched to specified weight
Agent, antioxidant and lubricant are fired, not only makes melt flow index height, forming temperature of the sheathing material in processing low, to
It is easy to processing and forming；Also, it is formed by the light weight of sheathing material, shrinking percentage is low, temperature tolerance, anti-flammability, mechanical performance (example
Such as tensile strength, bending strength, stretch modulus, bending modulus, notch impact strength) well, it is particularly suitable for large scale, thin-walled
Or the higher electronic equipment casing material of complicated and calorific value.
In addition, carbon black toner particle almost spherical, fast light, weather-proof, chemicals-resistant performance is splendid, and with high
Covering power and tinting strength, tinting power, therefore add carbon black toner and can significantly improve the shiny black glossiness of sheathing material, to promote production
The presentation quality of product.
Further, sheathing material of the invention is made of the raw material components of following parts by weight：50-60 parts of polyphenylene oxide is high
40-50 parts of impact-resistant polystyrene, 12-15 parts of fire retardant, 3.5-5 parts of antioxidant, 2-3 parts of lubricant, 1-2 parts of carbon black toner.
The density of above-mentioned sheathing material is 1.1g/cm according to ASTM D792 standard detections3Below；Vicat softening point temperature
It it is 96 DEG C or more according to ISO306 standard detections；Linear expansion coefficient according to ISO 11359-2-1999 standard detections be 65 μm/
DEG C or less；Flame retardant rating is V0 grades according to UL94 standard detections, excellent combination property.
