Description
Technical field
The invention belongs to capacitor film field, particularly a kind of weathering resistance capacitor film filler special and preparation method thereof.
Background technology
Film capacitor, owing to having much excellent characteristic, is therefore a kind of electrical condenser of excellent performance.Its property such as main is as follows: nonpolarity, insulation impedance is very high, frequency response characteristic excellence (frequency response is broad), and dielectric loss is very little.Based on above advantage, so film capacitor is widely used on mimic channel.Especially in the part of signal commissure, necessary frequency of utilization characteristic is good, the electrical condenser that dielectric loss is extremely low, can guaranteeing that signal is when transmitting, not having too large distortion situation and occurring.
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 be used in the frequency of sound appliances and quantity also more and more high.Simple polypropylene (PP) although film has heat-resisting, corrosion-resistant, the outstanding advantages of goods used vapour sterilization, and density is little, is the lightest general-purpose plastics; But there is low-temperature impact resistance difference in it, more aging shortcoming.Polystyrene (PS) film has high transparency, and electrical insulation capability is good, easy coloring, and processing fluidity is good, good rigidly and chemical resistance good, but more crisp, shock strength is low, easily occurs stress cracking, poor heat resistance and not resistance to boiling water; Therefore need to carry out modification to film.And increase gradually along with the range of application of electrical condenser, 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 by add filler modified come improving SNR.
Summary of the invention
The object of the present invention is to provide a kind of weathering resistance capacitor film filler special and preparation method thereof, this filler is toughened and reinforced to be made good use of, improve the flexural strength of film, bending elastic modulus, heat-drawn wire and dimensional stability simultaneously, add cold-resistant, heat-resisting, the weathering resistance of film, extend the work-ing life of electrical condenser.
Technical scheme of the present invention is as follows:
A kind of weathering resistance capacitor film filler special, is characterized in that being made up of the raw material of following weight part: nano-calcium carbonate 6-9, capsaicine 0.4-0.5, tripoly phosphate sodium STPP 0.6-0.8, Sodium hexametaphosphate 99 0.5-0.7, calcium lactate 1-1.4, Benzophenone carboxylic acid dianhydride 1.5-1.8, dimethyl formamide 1.2-1.5, tea saponin 1-1.4, Sodium Tetraborate 2-2.5, trichloroethyl phosphate 2.3-2.7, loess 60-65,4-6% hydrochloric acid are appropriate, water appropriate, auxiliary agent 15-20;
Described auxiliary agent is made up of the raw material of following weight parts: kaolin 5-7,2-2.5% sodium hydroxide solution 20-25, glyceryl monostearate 0.2-0.3, methacrylic ester 1-2, ethyl propenoate 0.4-0.7, activated calcium carbonate 10-15, ten trifluoro octyl group Trimethoxy silane 0.6-0.8, nano-graphite 1-1.3, tea saponin 0.1-0.2, Fruit of Cherokee Rose essential oil 0.1-0.2, Potassium Persulphate 0.1-0.2, water are appropriate; Preparation method is: kaolin mixes with 2-2.5% sodium hydroxide solution, be heated to 70-80 DEG C, stirring reaction 20-30 minute, filter, obtain filter residue, being washed to pH is 7-9, ovendry power is broken into the particle of 2-50 μm, then spray into ten trifluoro octyl group Trimethoxy silanes while stirring, grinding 20-25 minute, obtains modified kaolin; Again tea saponin is added in suitable quantity of water, add activated calcium carbonate again, add glyceryl monostearate, methacrylic ester, ethyl propenoate after stirring, after stirring, be warming up to 70-80 DEG C, add Potassium Persulphate, stirring reaction 20-30 minute, then add nano-graphite, continue stirring reaction 30-40 minute, dry, mix with modified kaolin and other remaining components, dispersion grinding becomes the particle of 2-50 μm, to obtain final product.
The preparation method of described weathering resistance capacitor film filler special, is characterized in that comprising the following steps:
(1) loess is sent in calcining furnace, at 700-800 DEG C, calcine 2-3 hour, take out and pulverize, cross 100 mesh sieves, then add 2-3 4-6% hydrochloric acid doubly, be heated to 50-70 DEG C, stir 10-20 minute, filter, obtain filter residue, pickling once, then is washed to neutrality more as stated above, filters, obtains particle;
(2) by Sodium hexametaphosphate 99, calcium lactate, Benzophenone carboxylic acid dianhydride, dimethyl formamide, tea saponin, Sodium Tetraborate, trichloroethyl phosphate mixing, grinding 20-30 minute, obtains mixture;
(3) material that (1) step and (2) step obtain is mixed with capsaicine, tripoly phosphate sodium STPP, add suitable quantity of water and stir into pureed, grind to form the slurry of 2-50 μm, spraying dry, then mix with other remaining components, to obtain final product.
Beneficial effect of the present invention
Filler of the present invention with the addition of nano-calcium carbonate, toughened and reinforcedly makes good use of, and improves the flexural strength of film, bending elastic modulus, heat-drawn wire and dimensional stability simultaneously; By using trichloroethyl phosphate, adding cold-resistant, heat-resisting, the weathering resistance of film, extending the work-ing life of electrical condenser; By using loess, reduce cost; The application of the invention auxiliary agent, can improve the dispersiveness of filler, reinforcing property, can improve thin film strength and tough.
