Summary of the invention
The object of the invention is provides a kind of transmission of electricity to fill pipe and preparation method thereof with matrix material according to above-mentioned deficiency, and this filling tube is good insulation preformance not only, and lightweight, and bendability is strong, and preparation method is simple.
Technical scheme of the present invention is as follows: a kind of transmission of electricity is filled pipe with matrix material, it comprises composite material pipe and foam-filled thing, it is characterized in that: described foam-filled thing is that following component is mixed to get according to parts by weight: the black material 100-130 of urethane part, urethane is expected 100-130 part in vain, anhydrous mineral filler 5-10 part.
Preferably, described anhydrous mineral filler is one or more mixing in anhydrous slufuric acid barium, Carbon Dioxide calcium, anhydrous magnesium carbonate, anhydrous silicic acid calcium.
Preferably, described anhydrous mineral filler particle diameter is 1250-3000 order.
A kind ofly prepare the method that matrix material for above-mentioned transmission of electricity is filled pipe, its step comprises: first filling tube pipe material inner wall carried out to grinding process and seal one end, then use foam-filled thing to fill, finally tubing is sealed to the other end, and the tubing after filling is obtained to matrix material filling pipe for described transmission of electricity after room temperature foaming and slaking; Described foam-filled thing is that following component is mixed to get according to parts by weight: the black material 100-130 of urethane part, urethane is expected 100-130 part in vain, anhydrous mineral filler 5-10 part.
Preferably, described grinding process is that pipe material inner wall is polished off to 0.5-2mm.
Preferably, after the black material of urethane that the anhydrous mineral filler that urethane is expected in vain, parts by weight are 5-10 part that described foam-filled thing filling process is is 100-130 part by parts by weight and parts by weight are 100-130 part mixes, obtain foam-filled thing, then pour matrix material into and fill in pipe.
Preferably, described urethane is expected first and anhydrous mineral filler mix and blend 2-3 minute in vain, then adds the black material of urethane and stir and after 30 seconds, obtain described foam-filled thing.
Preferably, described slaking is slaking 30 minutes at 60 ℃.
The transmission of electricity preparing by the inventive method is filled pipe with matrix material and is not only had advantages of that general compound material insulation pipe quality is light, and also can make the good insulating of inner tube when pipe insulation is good outside, simultaneously good bending property.Filling tube of the present invention well filled composite materials tubing is inner, prevent that steam and dust from entering tubing, guarantee the interior insulating property of tubing, be applicable to very much transmission of electricity and to insulating property, require high composite material pipe to use with composite material cross arm, compound material insulation rod etc., there is very strong practicality.
Embodiment
By specific embodiment, further illustrate the present invention below:
