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. The lubricant is advantageously a 2,4-dienoxy-6-aminoalkyl (-ene)-s-triazine, particularly 2,4-dienoxy-6-aminostearyl-s-triazine. Such triazines are also useful according to another embodiment of the invention as lubricants for wire with enamel insulation.
Claims9
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.degree. and 65.degree. 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.
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.sub.1 and R.sub.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.sub.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.sub.3 is a hydrogen radical or alkylene group which can cyclically be connected with R.sub.4, and wherein individual methylene groups in said alkylene group can be substituted by divalent oxo or thio groups.
