Description
Technical field
The invention belongs to capacitor film field, particularly a kind of high dispersive capacitor film filler special and preparation method thereof.
Background technology
Film capacitor, owing to having a lot of good characteristics, is therefore the outstanding electrical condenser of a kind of performance.Its property such as main is as follows: nonpolarity, insulation impedance is very high, frequency response characteristic excellent (frequency response is broad), and also dielectric loss is very little.Advantage based on above, so film capacitor is used on mimic channel in a large number.Especially in the part of signal commissure, necessary frequency of utilization characteristic is good, and the electrical condenser that dielectric loss is extremely low can guarantee that signal is when transmitting, and does not have too large distortion situation and occurs.
In the middle of all plastics film electric capacity, the characteristic of polypropylene (PP) electric capacity and polystyrene (PS) electric capacity is the most remarkable, thus in recent years PP electric capacity and PS electric capacity to be used in frequency and the quantity of sound appliances also more and more high.Simple polypropylene (PP) is although that film has is heat-resisting, corrosion-resistant, the outstanding advantages of goods used vapour sterilization, and also density is little, is the lightest general-purpose plastics; But it exists low-temperature impact resistance poor, easy aging shortcoming.Polystyrene (PS) film has high transparency, and electrical insulation capability is good, easy coloring, and processing fluidity is good, and good rigidly and chemical resistance are good, but more crisp, and shock strength is low, is prone to stress cracking, poor heat resistance and not resistance to boiling water; Therefore need to carry out modification to film.And along with the range of application of electrical condenser increases gradually, the performance of film also needs to improve, such as heat-resisting, low temperature resistant, acid and alkali-resistance, corrosion-resistant, intensity, ageing-resistant, UV resistant, fire-retardant, wear-resisting, toughness, the performance need such as shock-resistant improve, can be by adding the filler modified performance of improving.
