Abstract
The invention discloses a kind of degradable electrically insulating material, including polylactic acid 50～65 parts, natural rubber 5～20 parts, poly-hexanediol 3～16 parts, poly(hydrobutyl ester) 1～5 parts, polyethylene 30～45 parts, photosensitizer 2～8 parts, straw filler 18～30 parts, mica particles 15～25 parts, starch 5～22 parts and additive 1～7 parts.This electrically insulating material not only has good degradability, also has preferable electrical insulating property simultaneously, meets the application in electric insulation field.
Description
Technical field
The present invention relates to insulant, the degradable electricity of one particularly to electric wire is exhausted
Edge material.
Background technology
At electric field, polrvinyl chloride or crosslinked polyethylene etc. are excellent electric, mechanical due to it
Performance, is extensively used as electrically insulating material.But these insulating material of polymer cannot after scrapping
Natural degradation, can only bury then contaminated soil by burying or burning disposal, and burns generation
Harmful gas then contaminated air and natural environment.
Polylactic acid has excellent biocompatibility and an absorbability, nontoxic, nonirritant, it
In nature, under the effect of microorganism secretion enzyme, resolution is completely decomposed into CO2And H2O is right
Environmental nonpollution, is one of the most promising current biodegradable polymer.Polylactic acid is
Through being widely used in many fields.In electric wire field, polylactic acid is also by as degradable
The important candidate material of electrically insulating material.Although polylactic acid has good electric at normal temperatures
Performance, but at high temperature its insulating properties are the best, and therefore, polylactic acid is as electrically insulating material
Substitution material need to study further.
Summary of the invention
Solve the technical problem that and be: in order to reduce tradition electrically insulating material such as polrvinyl chloride or friendship
Join environment and the pollution of soil that polyethylene brings due to difficult degradation, and improve degradable poly
Lactic acid insulating properties at high temperature, it is provided that a kind of degradable electrically insulating material.
Technical scheme: in order to solve the problems referred to above, the invention provides a kind of degradable electricity exhausted
Edge material, including polylactic acid 50～65 parts, natural rubber 5～20 parts, poly-hexanediol 3～16 parts,
Poly(hydrobutyl ester) 1～5 parts, polyethylene 30～45 parts, photosensitizer 2～8 parts, straw filler 18～30
Part, mica particles 15～25 parts, starch 5～22 parts and additive 1～7 parts.
Preferably, the degradable electrically insulating material of described one, including polylactic acid 56 parts,
Natural rubber 8 parts, poly-hexanediol 5 parts, poly(hydrobutyl ester) 3 parts, polyethylene 35 parts, light
Quick dose 6 parts, straw filler 28 parts, mica particles 20 parts, starch 17 parts and additive 4
Part.
Preferably, described polylactic acid is L-type polylactic acid.
Preferably, the form of described polylactic acid is graininess or threadiness.
Preferably, described additive includes stabilizer and fire retardant.
The method have the advantages that and the invention provides a kind of degradable electric insulation material
Material, the material used due to composite electrical insulation material is almost degradable material, such as poly-breast
Acid is biodegradable, and natural rubber, straw filler and starch are all natural materials, polyethylene
Under the effect of photosensitizer degradable, so that prepared material has degradability；
Simultaneously because the interpolation of polyethylene etc., polylactic acid the best the asking of at high temperature insulating properties can be improved
Topic.Thus so that prepared degradable electrically insulating material, meet electric field exhausted to electricity
The requirement of edge material.
