Insulated wire using a resin composition
View Patent ↗An insulated wire uses a resin composition. The insulated wire includes a conductor; and an insulating material provided on the conductor, the insulating material includes a polyester resin in 100 parts by weight, a non-bromine flame retardant agent in 1-30 parts by weight, a polyorganosiloxane core-graft copolymer in 1-50 parts by weight, an inorganic porous filler in 0.1-50 parts by weight; and a hydrolysis resistance modifier in 0.05-10 parts by weight.
1. An insulated wire comprising:
a conductor; and
an insulating material with which the periphery of the-conductor is coated, the insulating material consisting of:
a resin composition consisting of:
a polybutylene terephthalate resin in 100 parts by weight;
a non-bromine flame retardant agent in 1-30 parts by weight, wherein the non-bromine flame retardant agent consists essentially of at least one of a phosphorous compound, a nitrogen compound having a triazine ring and a hydrous inorganic compound;
a polyorganosiloxane core-graft copolymer in 1-50 parts by weight;
an inorganic porous filler in 0.1-50 parts by weight; and
a hydrolysis resistance modifier in 0.05-10 parts by weight, wherein the phosphorous compound comprises a phosphoester compound expressed by a chemical formula (1):
wherein each of R1 . . . R8 expresses a hydrogen atom or an alkyl group of carbon number of 6 or less, n expresses an integer of 0 to 10, and R9 expresses a structure selected from a chemical formula (2):
and wherein the nitrogen compound having the triazine ring comprises an equimolar reactant of a cyanuric acid and a melamine.
2. The insulated wire according to claim 1 , wherein the hydrolysis resistance modifier comprises a carbodiimide compound.
3. The insulated wire according to claim 1 , wherein a thickness of the insulating material is 0.1 to 0.5 mm.
4. The insulated wire according to claim 1 , wherein a specific surface of the inorganic porous filler is not less than 5 m 2 /g.
5. The insulated wire according to claim 1 , wherein the inorganic porous filler comprises baked clay.
6. The insulated wire according to claim 4 , wherein the inorganic porous filler comprises baked clay.
7. The insulated wire according to claim 1 , wherein the phosphorous compound comprises phosphoester.
8. The insulated wire according to claim 1 , wherein the non-bromine flame retardant agent comprises both phosphoester and cyanuric acid melamine.
9. The insulated wire according to claim 1 , wherein the resin composition has a tensile elongation of more than 200% after 30 days at 85° C. and 85% relative humidity and has insulation resistance of greater than 1 MO·km in water of 90° C.
