Abstract

Abstract Lubricants for lacquered wires are provided comprising compounds of the type A-C-B, which compounds at room temperature have an ointment or soap-like consistency, wherein A is a chemical grouping containing reactive groups which permit chemical incorporation in a polymerizable impregnating resin system, B is a saturated or unsaturated aliphatic hydrocarbon radical, and C is a binding member in the form of a carbon, nitrogen, oxygen, or sulfur grouping.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 108 words
A lacquered wire having a lubricant film thereon; said lubricant having an ointment or soap-like consistency at room temperature and having a melting point between about 35° and 65° C comprising a compound of the formula A-C-B wherein A is a chemical grouping, having at least one ethylenically unsaturated group or having at least one reactive hydrogen atom which permit chemical incorporation into a polymerizable impregnating resin system; B is a saturated or unsaturated aliphatic hydrocarbon radical having from 8-24 carbons, and C is a binding member in the form of a divalent radical containing an element selected from the group consisting of carbon, nitrogen, oxygen and sulfur.
Claim 2
Dependent Claim 108 words
A lacquered wire having a lubricant film thereon; said lubricant having an ointment or soap-like consistency at room temperature and having a melting point between about 35° and 65° C comprising a compound of the formula A-C-B wherein A is a chemical grouping, having at least one ethylenically unsaturated group or having at least one reactive hydrogen atom which permit chemical incorporation into a polymerizable impregnating resin system; B is a saturated or unsaturated aliphatic hydrocarbon radical having from 8-24 carbons, and C is a binding member in the form of a divalent radical containing an element selected from the group consisting of carbon, nitrogen, oxygen and sulfur.
Claim 3
Dependent Claim 16 words
The lubricant of claim 1 wherein binding member C contains at least one reactive hydrogen atom.
Claim 4
Dependent Claim 14 words
The lubricant of claim 1 wherein said binding member C is an N-substituted amine.
Claim 5
Dependent Claim 125 words
The lubricant of claim 3 comprising a 2,4-dienoxy-6-aminoalkyl (-ene)-s-triazine of the general formula: ##STR11## Wherein R 1 and R 2 is each a radical selected from the group consisting of allyl, methallyl, ethallyl, propallyl, 3-ethylbutenyl-2,3-butenyl, 2,4-hexadienyl, crotyl and nonenyl; R 4 is an alkyl group having 1 to 20 carbon atoms, an alkylene cycloalkane group having from 4 to 10 carbon atoms, an alkylene aryl or heteroaryl group having from 7 to 10 carbon atoms or an alkenyl or alkynyl group having from 3 to 16 carbon atoms; R 3 is a hydrogen radical or an alkylene group which can cyclically be connected with R 4 , and wherein individual methylene groups in said alkylene group can be substituted by divalent oxo or thio groups.
Claim 6
Dependent Claim 11 words
The lubricant of claim 4 wherein said 2,4-dienoxy-6-amino alkyl(ene)-s-triazine is 2,4-diallyloxy-6-aminostearyl-s-triazine.
Claim 7
Dependent Claim 16 words
The lubricant of claim 1 wherein hydrocarbon radical B comprises from 14 to 20 carbon atoms.
Claim 8
Dependent Claim 19 words
The hydrocarbon radical of claim 1 selected from the cinnamic acid esters of lauryl, myristyl, cetyl and stearyl alcohol.
Claim 9
Dependent Claim 138 words
An enameled wire having a lubricant film thereon having an ointment or soap like consistency at room temperature said lubricant comprising a 2,4-dienoxy-6-aminoalkyl (-ene)-s-triazine of the formula: ##STR12## Wherein R 1 and R 2 is each a radical selected from the group consisting of allyl, methallyl, ethallyl, propallyl, 3-ethylbutenyl-2,3-butenyl, 2,4-hexadienyl, crotyl and nonenyl; R 4 is alkyl group having from 1 to 20 carbon atoms, an alkylene cycloalkane group having from 4 to 10 carbon atoms, an alkylene aryl or heteroaryl group having from 7 to 10 carbon atoms and an alkenyl or alkynyl group having from 3 to 16 carbon atoms; R 3 is a hydrogen radical or alkylene group which can cyclically be connected with R 4 , and wherein individual methylene groups in said alkylene group can be substituted by divalent oxo or thio groups.
Claim 10
Dependent Claim 138 words
An enameled wire having a lubricant film thereon having an ointment or soap like consistency at room temperature said lubricant comprising a 2,4-dienoxy-6-aminoalkyl (-ene)-s-triazine of the formula: ##STR12## Wherein R 1 and R 2 is each a radical selected from the group consisting of allyl, methallyl, ethallyl, propallyl, 3-ethylbutenyl-2,3-butenyl, 2,4-hexadienyl, crotyl and nonenyl; R 4 is alkyl group having from 1 to 20 carbon atoms, an alkylene cycloalkane group having from 4 to 10 carbon atoms, an alkylene aryl or heteroaryl group having from 7 to 10 carbon atoms and an alkenyl or alkynyl group having from 3 to 16 carbon atoms; R 3 is a hydrogen radical or alkylene group which can cyclically be connected with R 4 , and wherein individual methylene groups in said alkylene group can be substituted by divalent oxo or thio groups.
Claim 11
Dependent Claim 36 words
The lubricant of claim 8 wherein R 3 = H and R 4 is selected from the group consisting of lauryl, stearyl and alkyl having an average number of carbon atoms of from 14 to 18.
