Description
Technical field
The present invention relates to technical field of polymer materials, relate in particular to a kind of glass fiber reinforced PC composition material.
Background technology
Polycarbonate (PC) is common engineering plastics, with the glass fibre blending after finished product surfaces produce easily the macroscopic irregularitys such as floating fine, flow liner and spray.This is relevant with the intrinsic characteristic of polycarbonate, i.e. the structures shape performance.There are tested recipe and production technique in external major company, relatively common are 500R, 3412R, the 3413R of Saudi Arabia SABIC company on market, the GP413G of Korea S Samsung, GP4230G, GP4330G extensively are used in household electrical appliance, auto parts machinery field.
The product surface glass of the PC glass of these trades mark is uniformly dispersed, and the surperficial glass of the domestic modification PC of producer fiberglass product disperses inhomogeneous, reunites easily, and namely the glass on surface is the graniphyric distribution.
Handset sheathing material is the main CF3100 of Samsung, CF3200, CF3300, the CF3400 etc. of using at present.The G3310M of Japan Supreme Being people company and the 500R of SABIC company can not use on phone housing, and the PC+ glass of Samsung have used unique formula and production technique all because of the toughness reason, in the usage quantity of phone housing much larger than other modified plastics producers.Samsung has used special customized short glass fiber, the special producing technical process, thereby material cost is high especially.And domestic modification producer suffers from the immature restriction with being subject to equipment of technology, and it is balanced that glass fiber reinforced PC composite material is difficult to reach toughness, intensity and surface smoothness always.In order to have addressed this problem the contriver a kind of good toughness, intensity height were proposed once, the glass that surface smoothness is good strengthens the Pc composition material, its component and production method are that ZL201010227882.7 is disclosed, the disclosed this glass fiber reinforced PC composition material of ZL201010227882.7, composed of the following components by weight percentage:
Polycarbonate 45～61%
Saturated polyester 5～20%
Toughner 3～4%
Thermo-stabilizer 0.1～0.3%
Lubricant 0.7～1.1%
Glass fibre 25～35%.
Described polycarbonate glues or low adhesive aggregation carbonic ether in being, viscosity-average molecular weight is between 19000 to 25000; Described saturated polyester is polyethylene terephthalate.
Described toughner is the grafting POE of ethene one methyl acrylate and maleic anhydride, and described grafting POE is composed of the following components by weight percentage:
Ethene 0.5-1.5%
Methyl acrylate 0.5-1.5%
Maleic anhydride 0.5-1.5%
POE?95.5％-98.5。
Described thermo-stabilizer is N, N '-two-(3-(3,5-di-tert-butyl-hydroxy phenyl) propionyl) hexanediamine.
Described lubricant is the fatty acid amide of modification, and described modified fat acid acid amides is composite by ethylene bis stearic acid amide and silicone lubricant, and both ratios are 2.8～3.2:l.
Described glass fibre is short glass fiber, and diameter is 4～17 microns.
ZL201010227882.7 also discloses the preparation method of this glass fiber reinforced PC composition, comprise polycarbonate, saturated polyester, toughner, thermo-stabilizer, lubricant are mixed in moderate-speed mixers, mixing time is 3-7 minute, then adopt twin screw extruder to extrude, the expressing technique condition is: twin screw extruder one district's temperature is 180～260 ℃, two district's temperature are 180～260 ℃, three district's temperature are 180～260 ℃, four district's temperature are 180～260 ℃, 180～260 ℃ in five districts, compound time of delivery in screw rod is l～2 minute.
The disclosed this glass fiber reinforced PC composition of ZL201010227882.7, core is low viscous polycarbonate in adopting, and adds the auxiliary agents such as saturated polyester, self-control toughner, thermo-stabilizer, Lubricant Made by Ourselves, short glass fiber low viscous polycarbonate in described is carried out modification; Wherein adding the saturated polyester agent can increase intensity and the flowability of matrix material, and reduces the cost of whole prescription; Make toughner by oneself so that matrix material does not ftracture when playing screw, and can guarantee mobile phone not explosion when the following process oil spout; Thermo-stabilizer can prevent color jaundice or the variable color of finished product; Lubricant Made by Ourselves makes that glass is easier to be dispersed in the matrix material, makes finished product brighter and cleaner; Glass fibre makes matrix material treasure have very high intensity and toughness to reach the strength demand of mobile phone material.
Low viscous polycarbonate during the problem that the disclosed this glass fiber reinforced PC composition of ZL201010227882.7 exists is to adopt, the viscosity of polycarbonate is very large to the performance impact of the finished product in fact, and in low viscous polycarbonate cost higher, the price of general low viscous polycarbonate is more than a times of high viscosity polycarbonate price, obviously this has just caused the increase of cost, the disclosed this glass fiber reinforced PC composition of ZL201010227882.7 is very responsive to the viscosity of polycarbonate simultaneously, the compound scheme of adding the disclosed this glass fiber reinforced PC composition of ZL201010227882.7 is originally just comparatively complicated, and these characteristics are so that the technology controlling and process of the process of making of this glass fiber reinforced PC composition becomes very complicated.In addition, in recent years along with the development of smart mobile phone, the particularly development of high-end smartphones, some great variations have quietly occured in the application structure normal form of handset shell, wherein maximum variation is that the cooperation great majority of existing high-end smartphones housing have adopted the stud pre-buried structure, and the way of having abandoned between housing mutual flush structure and directly having opened screw at housing, at least can say the ready-made structure formation for main flow take the stud pre-buried structure as main and auxiliary flush structure, in this case, mainly as the disclosed this glass fiber reinforced PC composition of the ZL201010227882.7 of handset shell material, it is more than needed just to seem on some performance index too much, obviously it is not high requiring in take the stud pre-buried structure as main structural form such as the shock strength index, in addition, on industrial application, the structural part strained condition is that to bear the situation of static force in the majority, under this strained condition, obviously be flexural strength for the performance index of material outbalance, modulus in flexurees etc. affect the performance index of deformation, performance in essence a kind of irrational phenomenon more than needed, it is a kind of waste, moreover disclosed this its flame retardant effect of glass fiber reinforced PC composition of ZL201010227882.7 is very bad, has limited its range of application.In sum, obviously prior art has further improved necessity.
Summary of the invention
The object of the present invention is to provide a kind of improved glass fiber reinforced PC/ASA composition, the problem that exists to solve prior art.
A kind of improved glass fiber reinforced PC of the present invention/ASA composition is characterized in that its component is as follows by ratio of weight and the number of copies:
