Description
Technical field
The present invention relates to technical field of polymer materials, relate in particular to a kind of glass fibre reinforced PC alloy material and preparation method thereof.This kind alloy can be widely used in electrical and electronic component, as pressing plate, textile machines bearing shell, mechanical pump component or the like in the middle of power tool shell, body, support, freezer compartment of refrigerator drawer and vacuum cleaner part and outer rotor, T-valve, the electric wrench.
Background technology
Polycarbonate (PC) is a kind of increasingly extensive engineering plastics of using, and it has mechanical property, thermal characteristics and the electrical property of comprehensive stability, and its output only is only second to nylon (PA).It has shock resistance, and dimensional stabilizing is heat-resisting, the transparent performance that waits excellence.But its some shortcoming such as processing difficulties, the goods unrelieved stress is big, is easy to stress cracking, and to the breach sensitivity, poor solvent resistance and wear no resistance etc. has simultaneously all restricted its application in a lot of fields.The co-blended aurification is a kind of important means of PC modification, and it makes the PC performance excellent more, thereby has widened its Application Areas.
Strengthening PC is one of industrialized the earliest PC modified product, and glass fiber reinforced PC is present most important enhancing PC material.With respect to PC, on performance, improved fatigue resistance and the hardness of PC, reduce the susceptibility of goods counter stresses and reduced cost.Tensile strength, flexural strength, modulus in flexure, compressive strength, wear resistance, reduction water-absorbent, creep and the molding shrinkage of PC have been improved simultaneously.Very big to the demand that strengthens PC in the market, domestic considerable enterprise has also done a lot of research work on the one hand at this, obtains sizable progress and achievement.
The weak point of glass fiber reinforced PC is that the toughness of material descends, and floating fine phenomenon is difficult to control, and the finished product surface smoothness is lower, has limited the widespread use of glass fiber reinforced PC.
Summary of the invention
The technical problem to be solved in the present invention is being, overcoming the floating fibre of traditional glass fibre reinforced PC alloy material is difficult to control and the bad defective of finished product surface luster property, a kind of floating fibre of control surface that is easy to is provided, the glass fibre reinforced PC alloy material that the finished product surface gloss is high also will provide the preparation method of this kind glass fibre reinforced PC alloy material simultaneously.
The technical problem to be solved in the present invention is being, overcomes the defective that traditional glass fibre reinforced PC alloy material toughness descends, provide a kind of can toughness glass fibre reinforced PC alloy material preferably.
For solving the problems of the technologies described above, the present invention proposes following technical scheme: a kind of glass fibre reinforced PC alloy material, and it is prepared from by following component: polycarbonate: 25～55%; Polybutylene terephthalate: 10～55%; Toughener: 10～30%; Toughner: 3.0～7.0%; Coupling agent: 0.3～0.5%; Oxidation inhibitor: 0.1～1.0%; Anti-glass emergence on the surface agent: 0.3～0.7%; Above percentage ratio is weight percent.
Wherein, described toughner is MBS resin system methyl methacrylate (M), divinyl (B), vinylbenzene (S) terpolymer.Described toughener is a glass fibre reinforcement.Described oxidation inhibitor comprises phenolic antioxidant four [β-(3 ', 5 '-di-t-butyl-4 '-hydroxy phenyl) propionic acid] pentaerythritol ester 0.05-0.5% and phosphite ester kind antioxidant (2,4 di-tert-butyl-phenyl) tris phosphite 0.0 5-0.5%.The modified product that described anti-glass emergence on the surface agent is an ethylene bis stearamide.
Above-described glass fibre reinforced PC alloy material can be prepared from by following component: polycarbonate 25～45%; Polybutylene terephthalate 25～55%; Toughener 10～25%; Toughner 5.0～7.0%; Coupling agent 0.3～0.5%; Oxidation inhibitor 0.3～1.0%; Anti-glass emergence on the surface agent 0.3～0.6%; Above percentage ratio is weight percent.
The preparation method's of glass fibre reinforced PC alloy material of the present invention technical scheme may further comprise the steps:
Step 1: take by weighing each component by above-mentioned weight percent;
Step 2: with polycarbonate and polybutylene terephthalate is matrix, adds toughener, toughner, coupling agent, the anti-glass emergence on the surface agent of oxidation inhibitor and an amount of dispersion agent and mixes in high-speed mixer;
Step 3: each component that will mix places twin screw extruder, through the melting mixing extruding pelletization.
Wherein, this twin screw extruder one district's temperature: 230～235 ℃, two district's temperature: 240～245 ℃, three district's temperature: 250～255 ℃, four district's temperature: 250～260 ℃, five district's temperature: 240～245 ℃, six district's temperature: 230～235 ℃, residence time 1-2 minute, engine speed: 300-350rpm.
Wherein, in step 2, the blended time is 3-5 minute in high-speed mixer.
The present invention has overcome the floating fine phenomenon of traditional glass fiber reinforced PC material and has been difficult to control defect of insufficient with the decline of surface luster property, the invention has the beneficial effects as follows: the surface of product does not have floating fine, glossiness is good, certain light transmission is arranged, guaranteeing to strengthen the original inflexible of PC material simultaneously, can improve the surface gloss that strengthens PC significantly, can be widely used in electrical and electronic component, as the power tool shell, body, support, freezer compartment of refrigerator drawer and vacuum cleaner part and outer rotor, T-valve, pressing plate in the middle of the electric wrench, the textile machines bearing shell, mechanical pump component etc.
The present invention can also overcome the defective that traditional glass fiber reinforced PC toughness of material descends by the content of control PBT, in the rigidity that guarantees the glass fiber reinforced PC material, improve under the surface smoothness prerequisite of product, improve the toughness of the material of glass fiber reinforced PC, further enlarged the range of application of the material of glass fiber reinforced PC.

The present invention improves the fine effect of anti-floating of whole system effectively by add a certain proportion of PBT (polybutylene terephthalate) in the system of PC+GF.Its mechanism is to add the low PBT of viscosity in the system of the high PC+GF of viscosity, and PBT belongs to temperature-sensitive material, and its mobile raising of the raising of temperature is very fast.Under 270 ℃-280 ℃ injecting condition, the PBT flowability is fine, and " race " is easy to the inside that PC and glass are coated up front, thus be exposed mostly be PBT greatly, thereby improved the surface luster property of moulding.
Material property contrast table analysis by table 2 embodiment 1-6 as can be known, the present invention adopts the PC of several different ratioss, the mass percent of PBT, produce the enhancing PC/PBT alloy material product of various glass fiber contents, especially embodiment 3 to 6 adds the fiber material poor toughness improving conventional P C, the surface floating fiber while more rambunctious, can improve the use properties of PC/PBT alloy material again.The PC/PBT alloy material can be widely used in electrical and electronic component, as pressing plate, textile machines bearing shell, mechanical pump component etc. in the middle of power tool shell, body, support, freezer compartment of refrigerator drawer and vacuum cleaner part and outer rotor, T-valve, the electric wrench.
According to the above, advantage of the present invention is: the surface of product is without floating fine, and glossiness is good, and certain light transmission is arranged, and toughness is better, and intensity is high, can be used to substitute the product to the less demanding PC+GF of anti-flammability.
