Abstract
The invention relates to a method for producing adhesive glue for a busbar sleeve at low voltage side of a transformer. The method comprises the steps of adding a base material- fluorine-containing hydroxyl dimethyl silicone polymer into an airtight kneading machine, adding reinforcing filler, electric corrosion resistant filler and pigment, raising the temperature, heating up, treating for 4 hours at reduced pressure, milling three times by a three-roller machine, transferring into a stirrer with double planets, adding a catalyst, reacting for 2 hours by a cross-linking agent, starting a hydraulic machine under nitrogen protection and pressing the adhesive glue into an airtight pipe. The method is simple and is convenient to use.
Description
Technical field
The present invention relates to a kind of production method of bonded adhesives, particularly the production method of step down side busbar sheath bonded adhesives.
Background technology
At present, the short circuit that step down side busbar causes because of animalcule, the alternate overlap joint of foreign matter is tripped power outage generation frequently, originally exist and need to will equipment put heat shrinkage insulation cover after dismounting with heat shrinkage insulation cover, again equipment is installed after shrinking through scene heating high bake sheath.Time-consuming, and because of not ageing-resistant, can not ensure for a long time its reliability.Due to needs good insulation preformance, anti-aging, so common glue can not be used for the bonding of step down side busbar sheath.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of production method of step down side busbar sheath bonded adhesives, its technique is simple, easy to use.
The present invention solves the technical scheme that its technical problem takes: comprise the following steps: to add fluorine-containing hydroxyl polydimethylsiloxane to be base-material, to add reinforced filling, resistance to galvanic corrosion to damage filler, pigment again in sealable kneader; intensification, heating, reduced pressure treatment 4 hours; after three-roller is milled thin-pass three times; be transferred to band double-planet agitator; add catalyzer, linking agent reaction 2 hours, under nitrogen protection, primer fluid press press-fits adhesive glue to sealable pipe.
The present invention has following advantages: 1), avoided master row insulating dismounting, baking again assembling numerous and diverse operation, saved power off time; 2), excellent electrical insulation capability, more than dielectric strength reaches 25KV/m, electrical erosion resistance TMA4.5 level, hinders right property and reaches FV-0 level, lasting is ageing-resistant, anti-electric-arc can effectively protect busbar not discharge under abnormal conditions; 3), physical strength is up to 4.5Mpa, strong, the resistance to ozone of weather resisteant, acid-and base-resisting, salt and chemical corrosion, reach 20 years work-ing life; 4), density is little, lightweight; 5), constructional method is easy.Can prevent animalcule foreign matter overlap joint phase fault trip accident for transformer low voltage insulation.
Embodiment
The present invention includes the following step: in sealable kneader, add fluorine-containing hydroxyl polydimethylsiloxane 40-60 part, add reinforcing filler 20-30 weight part, resistance to galvanic corrosion to damage filler 20-30 weight part again, pigment 1-3 weight part heats up, is heated to 180 degree, decompression 0.095MP
aprocess 4 hours, after three-roller is milled thin-pass three times, be transferred to band double-planet agitator and add catalyst weight part, linking agent 1-3 weight part, react 2 hours under nitrogen protection primer fluid press adhesive glue is press-fited to sealable pipe.
Described catalyzer commodity methyl tributanoximo silane by name.
Described linking agent agent commodity dibutyltin oxide by name.
Described fluorine silicon p-aramid fiber is rubber unvulcanizate.
Described pigment is ferric oxide, chromium sesquioxide or titanium dioxide.
