(4) adding accounts for gross mass proportioning 0.5%～15% double-deck thermoplastic structure's microballoon, stirs, and makes the half-dry environment-friendly insulation filling compound for electrician equipment, stores for future use.
Preferably: described synthetic polypropylene hydrocarbon ils is poly-a-olefin oil or polyisobutylene oil, and described concise white mineral oil is a hydrocracking mineral oil; Described double-deck thermoplastic structure's microballoon comprises acrylonitrile copolymer housing and hydrocarbon air bag, and described hydrocarbon air bag is that isopentane is the 2-methybutane; The delamination inhibitor of stating is styrene-ethylene and propylene-based block copolymer or ethylene-propylene rubber solution; Described pour-point depressant composition is polyacrylate or Poly alpha Olefins (PAO) class; Described silicon dioxide is the aerosol of hydrophobic type and/or hydrophilic aerosil or silicon dioxide; Described antifungal agent is the antifungal agent of 2-octyl group-4-with the thiazoline structure; Described antioxidant is liquid phenols or four [β-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester.
The present invention compared with prior art has following advantage and beneficial effect:
(1) realized by of the transformation of oily formula filler to the dry type filler
The capacitor of traditional filling type for example, owing between big case shell and cell capaciator, be filled with extremely several thousand kilograms a large amount of flammable insulating oil (transformer oil or alkylbenzene oil) of hundreds of kilogram, product easy to leak oil, inflammable and explosive under the fault condition, contaminated environment, weight is big, and will refuel, change oil etc., it is many that maintenance work is wanted relatively.And compound density of the present invention has only about 0.45g/ml, and the density of insulating oil probably is 0.93g/ml, and half is many so the amount of unit volume has reduced, and has realized that oily formula fills the transformation of filling to half dry type.
(2) environment-friendly semi-dry type
This invents described half dry type filled composite and presents half-dried soft granular structure its enough dried is easy to is simply cleaned with general cleaning cloth.Do not need to use specific solvent to clean this original characteristic, filling process can reduce the air pollution that solvent evaporation causes, thus the protection environment.In addition, this series products is in case filling need not to change, and the time that saving brings because of regular maintenance reaches manually to be expended.
(3) superior thixotropic property, cold filling, technology is simple
Half dry type filled composite of the present invention is to select thermoplasticity double-decker micro-sphere material and make meticulously based on the fluid with thixotropy and long-term thermal stability, helps abundant filling.Thixotropic property at normal temperatures and superior can solve in production, transportation and the flow process and may be subjected to external force effects such as bending, vibration, impact, and buffering stress carries out more effectively simple the filling and maintenance.
It is soft that half dry type filled composite of the present invention keeps at low temperatures, can at room temperature use pad device directly to fill at a high speed.Simultaneously, can require according to the difference of the condition of filling soft durometer is adjusted accordingly to satisfy technological requirement.
Cold filling paste is a kind of insulating properties colloid that is formed with network configuration by the physical crosslinking effect, this colloid does not under static state flow, the height hydrophobic, can be transformer, cable and other electrical equipment provide good water-tight performance, have excellent high temperature performance simultaneously, and in the structural deterioration of shear action lower network, viscosity reduces significantly, becomes flowable fluid, and shearing force is recovered original network configuration again after removing immediately.
(4) anti-fungal property good (the biological environmental production performance is good)
By Bell Laboratory GR-20-CORE, the R6-34 standard-required, filled composite reply bacterium does not have nutrition.
The demonstrations of reporting the result that have some to corrode power equipment about bacterium, often equipment by bacterium by its manhole or be exposed to wet environment and airborne part corrodes.Bacterium and fungi can grow therein with this understanding.For preventing this situation, we confirm that by the antimycotic test of Britain PRA waterproof paste of the present invention does not have nutrition to the growth of fungi and bacterium.
(5) superior electrical insulation capability
Since selected delamination inhibitor, double-deck thermoplastic structure's microballoon, materials such as silicon dioxide all have excellent electric insulating, make half-dry environment-friendly filled composite of the present invention have superior electrical insulation capability, and the normal temperature specific insulation can reach 10
16Can be widely used in the preparation of half dry type transformer, cable and other insulation filling compound for electrician equipment.
In a word, half-dry environment-friendly insulation filling compound for electrician equipment of the present invention has superior electrical property, the idea that meets the few oiling of safety and environmental protection, and, during filling, cable and other electrical equipment be with a wide range of applications because of the advantage of uniqueness (energy-conservation, technology is easy, easy to use, cleanliness without any pollution) at present transformer.And the thixotropic filled composite of half-dry environment-friendly insulation filling compound for electrician equipment of the present invention for filling at normal temperatures, can replace traditional filler that transformer, cable and other electrical equipment are filled that is used for fully, and have well-content effect.
