The invention relates to the technical field of engineering plastics, in particular to a polycarbonate composite material and a preparation method and application thereof.
Background
Wafers are basic raw materials for manufacturing semiconductor devices, and with the development of the semiconductor industry, the precision and precision of semiconductors are higher and higher, and the wafers are easily damaged in the processes of transportation and storage. In order to solve this problem, the wafer box of the apparatus for packaging and transporting is required to have good antistatic function, and protect the wafer from static damage and dust accumulation during storage of the transport box.
PC (polycarbonate) has excellent comprehensive performance, high mechanical strength, good impact resistance and high dimensional precision, and is widely applied to the semiconductor packaging industry, wherein the most important product is a wafer box. But the surface resistance of PC is higher, and the antistatic property is poor; the antistatic modification of the PC is required to meet the use requirements of the wafer box. The carbon nano tube has good conductivity, can improve the antistatic property of PC, but has poor compatibility with PC resin, cannot realize uniform dispersion in PC material, has poor effect of improving the antistatic property of PC, and can influence the mechanical property, especially the impact property of the material.
Chinese patent application CN110551378A discloses a halogen-free flame-retardant PC/carbon nanotube conductive material and a product thereof, wherein the resistivity of the material is reduced by adding 4% of carbon nanotubes; however, the carbon nano tube has large addition amount, poor dispersibility in PC and poor mechanical property of the material; chinese patent application CN105176036A discloses a wear-resistant antistatic bacteriostatic PC composite material, which is prepared by adding grafted MWCNT-g-SiO into PC2‐NH2g-PC to improve the dispersibility of MWCNTs (multi-walled carbon nanotubes) in PC. But the actual improvement effect on the antistatic performance of the material is not good, and the obtained material has higher surface resistivity and is not beneficial to the release of static electricity; and the grafting reaction process of the MWCNT is complex and the grafting effect is uncontrollable, and a highly toxic substance DBTO (dibutyltin oxide) is used in the grafting process, so that the production and the application of industrial products are not facilitated.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention aims to provide a polycarbonate composite material which has good antistatic performance and excellent mechanical properties.
Another object of the present invention is to provide a method for preparing the polycarbonate composite material.
The invention is realized by the following technical scheme:
the polycarbonate composite material comprises the following components in parts by weight:
100 parts of polycarbonate;
10-30 parts of ultrahigh molecular weight polyethylene;
3-15 parts of maleic anhydride grafted polyethylene;
1-10 parts of carbon nano tube.
The specification and parameters of the polycarbonate are not particularly limited, since the dispersibility of the carbon nanotubes in the polycarbonate resin matrix is improved. Tests prove that the polycarbonate resin has a good technical effect on polycarbonate with the weight-average molecular weight of 14000-35000; preferably, the weight average molecular weight of the polycarbonate for the wafer cassette is 18000 to 22000.
The weight average molecular weight of the ultra-high molecular weight polyethylene is 80-200 ten thousand; preferably, the weight average molecular weight of the ultra-high molecular weight polyethylene is 100 to 120 ten thousand.
In the maleic anhydride grafted ultra-low molecular weight polyethylene, the grafting rate of the maleic anhydride is 0.5-1 wt%.
The maleic anhydride grafted ultra-low molecular weight polyethylene can be prepared by melting and grafting peroxide (dicumyl peroxide (DCP)), maleic anhydride and ultra-low molecular weight polyethylene, and the grafting rate is controlled by adjusting the content of the DCP and the maleic anhydride and a melting and grafting process.

Maleic anhydride is easy to react with polar groups such as carboxyl, hydroxyl and the like on the surface of the carbon nano tube, so that the compatibility of the carbon nano tube and the ultra-low molecular chain polyethylene is improved; because the molecular weight of the ultra-low molecular chain polyethylene is very small, the molecular chain segment has very strong movement capability, and the ultra-low molecular chain polyethylene can well infiltrate into the surface of the carbon nano tube and open the carbon nano tube which is mutually entangled; in addition, the maleic anhydride grafted ultra-low molecular weight polyethylene has both a nonpolar ethylene chain segment and a polar maleic anhydride group, so that the polyethylene has good compatibility with nonpolar polymer ultra-high molecular weight polyethylene and polar polymer polycarbonate, and carbon nanotubes are distributed on a phase interface of the ultra-high molecular weight polyethylene and the polycarbonate, so that the dispersion of the carbon nanotubes in a polycarbonate resin matrix is promoted, and the carbon nanotubes are uniformly dispersed in the polycarbonate resin matrix.
Preferably, the carbon nanotube of the present invention is at least one selected from the group consisting of an array-type multi-wall carbon nanotube, an array-type single-wall carbon nanotube, and an array-type double-wall carbon nanotube. The array type carbon nano tube has good conductivity and dispersibility, is easier to realize dispersion in the polycarbonate material, and improves the conductivity of the material; more preferably, the carbon nanotubes are selected from multi-walled carbon nanotubes of the array type.
According to the material performance requirement, the polycarbonate composite material also comprises 0-1 part by weight of at least one of an antioxidant and a lubricant; the antioxidant is selected from one or more of tetra [ beta- (3, 5-di-tert-butyl-4-hydroxyphenyl) propionic acid ] pentaerythritol ester, tris ( 2.4, 4-di-tert-butyl benzene grade) phosphite ester or N, N' -bis- (3- (3, 5-di-tert-butyl-4-hydroxyphenyl) propionyl) hexamethylenediamine; the lubricant is selected from any one or more of pentaerythritol stearate, silicone, erucamide or ethylene bisstearoyl.
The invention also provides a preparation method of the polycarbonate composite material, which comprises the following steps: weighing ultrahigh molecular weight polyethylene, maleic anhydride grafted ultralow molecular weight polyethylene and carbon nanotubes according to the proportion, uniformly mixing, adding into a double-screw extruder, and extruding through the double-screw extruder to obtain carbon nanotube master batches; and then uniformly mixing the carbon nanotube master batch and the polycarbonate, and performing melt mixing extrusion, cooling and granulation at 260-290 ℃ by using a double-screw extruder to obtain the polycarbonate composite material.
The invention also provides application of the polycarbonate composite material, and the polycarbonate composite material can be used for preparing a wafer box.
Compared with the prior art, the invention has the following beneficial effects:
according to the invention, the maleic anhydride is added to graft the ultra-low molecular weight polyethylene, so that the carbon nano tube is dispersed in the two-phase interface of the ultra-low molecular weight polyethylene and the polycarbonate and further uniformly dispersed in the polycarbonate resin matrix, the defect of poor compatibility of the carbon nano tube and the polycarbonate is solved, the antistatic property of the material can be obviously improved, and the impact resistance of the material is improved.
