Abstract
The present invention relates to a kind of production method of step down side busbar sheath bonded adhesives.Comprise the following steps: that in sealable kneader, add fluorine-containing hydroxyl polydimethylsiloxane is base-material, adds reinforced filling, resistance to galvanic corrosion damage filler, pigment again; heat up, heating, reduced pressure treatment 4 hours; after three-roller mills thin-pass three times; be transferred to band double planetary mixer; add catalyzer, linking agent reacts 2 hours, adhesive glue press-fits in sealable pipe by primer fluid press under nitrogen protection.Its technique is simple, easy 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 tripping operation power outage that step down side busbar causes because of animalcule, the alternate overlap joint of foreign matter occurs frequent, original need equipment to dismantle with the existence of heat shrinkage insulation cover after put heat shrinkage insulation cover, through scene, equipment is installed by heating high bake sheath after shrinking again.Time-consuming, and because of not ageing-resistant, its reliability can not be ensured for a long time.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 in sealable kneader fluorine-containing hydroxyl polydimethylsiloxane be base-material, add reinforced filling again, filler, pigment are damaged in resistance to galvanic corrosion; heat up, heating, reduced pressure treatment 4 hours; after three-roller mills thin-pass three times; be transferred to band double planetary mixer; add catalyzer, linking agent reacts 2 hours, adhesive glue press-fits in sealable pipe by primer fluid press under nitrogen protection.
The present invention has following advantages: 1), avoid master row insulating dismounting, toast numerous and diverse operation of assembling again, save power off time; 2), excellent electrical insulation capability, dielectric strength reaches more than 25KV/m, electrical erosion resistance TMA4.5 level, and hinder right property and reach FV-0 level, lasting is ageing-resistant, anti-electric-arc, can not discharge by available protecting busbar in abnormal cases; 3), physical strength 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 from overlapping phase fault trip accident for transformer low voltage insulation then.
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 damage filler 20-30 weight part again, pigment 1-3 weight part heats up, be heated to 180 degree, decompression 0.095MP
aprocess 4 hours, after three-roller mills thin-pass three times, be transferred to band double planetary mixer 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 catalyst commercial product is called methyl tributanoximo silane.
Described linking agent agent commodity are called dibutyltin oxide.
Described fluorine silicon p-aramid fiber is rubber unvulcanizate.
Described pigment is ferric oxide, chromium sesquioxide or titanium dioxide.
It is aluminium hydroxide that filler is damaged in described resistance to galvanic corrosion.
Described reinforcing filler commodity are called the Fumed silica of silicon-dioxide.
