Description
Technical field
The present invention relates to insulating material, particularly the degradable electrically insulating material of the one of electric wire.
Background technology
At electric field, polyvinyl chloride or crosslinked polyethylene etc., due to its excellent electric, mechanical property, are extensively used as electrically insulating material.But these insulating material of polymer cannot natural degradation after scrapping, and by burying or burning disposal, can only bury then contaminated soil, burn obnoxious flavour then polluted air and the physical environment produced.
Poly(lactic acid) has excellent biocompatibility and absorbability, nontoxic, nonirritant, and it is decomposed into CO completely at occurring in nature resolution under the effect of microorganism secretion enzyme
2and H
2o, environmentally safe is one of the most promising current biodegradable polymkeric substance.Poly(lactic acid) has been widely used in many fields.In electric wire field, poly(lactic acid) is also by the important candidate material as degradable electrically insulating material.Although poly(lactic acid) has good electric property at normal temperatures, at high temperature its insulating property are not good, and therefore, poly(lactic acid) need further research as the equivalent material of electrically insulating material.
Summary of the invention
The technical problem solved is: in order to reduce the pollution of environment that traditional electrical insulating material brings due to difficult degradation as polyvinyl chloride or crosslinked polyethylene and soil, and improve degradable poly lactic acid insulating property at high temperature, a kind of degradable electrically insulating material is provided.
Technical scheme: in order to solve the problem, the invention provides a kind of degradable electrically insulating material, comprise poly(lactic acid) 50 ~ 65 parts, natural rubber 5 ~ 20 parts, poly-hexylene glycol 3 ~ 16 parts, poly(hydrobutyl ester) 1 ~ 5 part, polyethylene 30 ~ 45 parts, photosensitizers 2 ~ 8 parts, stalk filler 18 ~ 30 parts, mica particles 15 ~ 25 parts, starch 5 ~ 22 parts and additive 1 ~ 7 part.
Preferably, the degradable electrically insulating material of described one, comprises poly(lactic acid) 56 parts, natural rubber 8 parts, poly-hexylene glycol 5 parts, poly(hydrobutyl ester) 3 parts, polyethylene 35 parts, photosensitizers 6 parts, stalk filler 28 parts, mica particles 20 parts, starch 17 parts and additive 4 parts.
Preferably, described poly(lactic acid) is L-type poly(lactic acid).
Preferably, the form of described poly(lactic acid) is particulate state or threadiness.
Preferably, described additive comprises stablizer and fire retardant.
The present invention has following beneficial effect: the invention provides a kind of degradable electrically insulating material, the material used due to composite electrical insulation material is almost degradable material, if poly(lactic acid) is biodegradable, natural rubber, stalk filler and starch are all natural materialss, polyethylene is degradable under the effect of photosensitizers, so makes prepared material have degradability; Simultaneously due to the interpolation of polyethylene etc., the poly(lactic acid) problem that at high temperature insulativity is not good can be improved.Thus, make prepared degradable electrically insulating material, meet the requirement of electric field to electrically insulating material.
