Abstract
The invention provides special packing for an anti-radiation capacitor film. The special packing comprises the following materials of, by weight, 10-15 parts of medium density polyethylene, 10-15 parts of meerschaum, 3-5 parts of triphenyl phosphate, 3-5 parts of magnesium stearate, 1-2 parts of lauryl diethanolamine, 1-2 parts of titanium acetylacetonate, 0.7-0.9 part of nano tungsten trioxide, 0.1-0.2 part of rose essential oil, 50-55 parts of municipal sludge, a proper amount of 5-7% muriatic acid, a proper amount of water and 15-20 parts of additives. The meerschaum is added to the packing, and therefore the insulation performance, the corrosion resistant performance, the radiation resistance, the thermal stability performance and the like of the film are improved; corrosion of a capacitor can be slowed down by adding the lauryl diethanolamine; the municipal sludge is used, therefore, the cost is reduced, the fineness is high, and the reinforcement performance is good; the additives are used, therefore, the dispersibility and the reinforcement performance of the packing can be improved, and the strength and the impact toughness of the film can be improved.
Description
Technical field
The invention belongs to capacitor film field, particularly a kind of radioprotective 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 excellence (frequency response broadness), and also dielectric loss is very little.Based on above advantage, 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 in the time 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, easily 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 film to carry out modification.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.
Summary of the invention
The object of the present invention is to provide a kind of radioprotective capacitor film filler special and preparation method thereof, this filler has improved the insulation of film, anticorrosive, radioprotective and the performance such as thermally-stabilised.
Technical scheme of the present invention is as follows:
A kind of radioprotective capacitor film filler special, is characterized in that being made up of the raw material of following weight part: medium-density polyethylene 10-15, sepiolite 10-15, triphenylphosphate 3-5, Magnesium Stearate 3-5, lauroyl diethanolamine 1-2, titanium acetylacetone 1-2, nano tungsten trioxide 0.7-0.9, Flos Rosae Rugosae quintessence oil 0.1-0.2, municipal sludge 50-55,5-7% hydrochloric acid is appropriate, water appropriate, auxiliary agent 15-20;
Described auxiliary agent is made up of the raw material of following weight part: zinc sulfate 0.5-0.8, nano barium sulfate 1-1.5, lime powder 2-3, EDETATE SODIUM 0.2-0.4, benzotriazole 0.2-0.3, silicon ash 5-7,2-3% hydrochloric acid soln 10-15, sodium oleate 0.1-0.2, silane coupling agent KH-572 0.1-0.2, ethyl propenoate 2-3, diethylene glycol dibutyl ether 1-2, butyl (tetra) titanate 0.1-0.2, ethylene glycol amine 0.1-0.2, fatty acid amine 0.5-0.8, ammonium persulphate 0.1-0.2, water are appropriate; Preparation method is: silicon ash is mixed with 2-3% hydrochloric acid soln, be heated to 50-60 DEG C, stirring reaction 20-30 minute, filter, obtain filter residue, being washed to pH is 6-8, dry, mix with zinc sulfate, EDETATE SODIUM, benzotriazole, sodium oleate, diethylene glycol dibutyl ether, butyl (tetra) titanate, ethylene glycol amine, fatty acid amine again, grind 15-20 minute, obtain silicon ash particle; Again silane coupling agent KH-572 is added in suitable quantity of water, add again silicon ash particle, after stirring, add ethyl propenoate, after stirring, be warming up to 70-80 DEG C, add ammonium persulphate, stirring reaction 20-30 minute, then add lime powder, continue stirring reaction 30-40 minute, dry, mix with other remaining components, dispersion grinding becomes the particle of 2-50 μ m, to obtain final product.
The preparation method of described radioprotective capacitor film filler special, is characterized in that comprising the following steps:
(1) municipal sludge is sent in calcining furnace, at 700-800 DEG C, calcined 2-3 hour, take out and pulverize, cross 100 mesh sieves, add again 2-3 5-7% hydrochloric acid doubly, be heated to 50-70 DEG C, stir 10-20 minute, filter, filter residue, pickling once, then is washed to neutrality more as stated above, filter, obtain particle;
(2) sepiolite is pulverized, crossed 80 mesh sieves, mix with medium-density polyethylene, sepiolite, triphenylphosphate, Magnesium Stearate, lauroyl diethanolamine, titanium acetylacetone, nano tungsten trioxide, Flos Rosae Rugosae quintessence oil, grind 20-30 minute, obtain mixture;
(3) mixing of materials (1) step and (2) step being obtained, adds suitable quantity of water to stir into mud shape, grinds to form the slurry of 2-50 μ m, and spraying is dry, then mixes with other remaining components, to obtain final product.
Beneficial effect of the present invention
