Abstract
The invention discloses modified polyester wire enamel, belongs to the field of insulating paint and solves the problem of poor heat resistance of the conventional polyester wire enamel. The modified polyester wire enamel comprises raw materials in parts by weight as follows: 30-40 parts of organosilicone modified polyethylene terephthalate, 20-30 parts of cresol, 10-20 parts of xylene, 10-15 parts of terephthalic acid, 5-10 parts of isophthalic acid, 10-20 parts of neopentyl glycol, 12-18 parts of glycerin, 10-20 parts of dimethylformamide, 10-15 parts of N-methylpyrrolidone, 5-10 parts of nano-silica, 1-3 parts of polyether-polyester modified organo-siloxane, 1-5 parts of acrylate, 1-2 parts of Phenol-formaldehyde resin and 2-5 parts of adipic acid. The modified polyester wire enamel has low production cost, has the characteristics of high solids and low viscosity, has good mechanical properties after being cured to form a film and has good thermal shock resistance.
Description
Technical field
The present invention relates to a kind of modified polyester wire enamel, belong to field of paint.
Background technology
Enameled wire is a kind of important electrical insulating material, and on the wires such as copper, aluminium, mauganin, coat polymer insulation paint according to specific production technique exactly and be prepared from, this specific insullac is exactly wire enamel.Wire enamel can make to produce good insulation layer between wire and wire in winding, to improve and the performance of stable enameled wire.
Polyester wire enamel has good mechanical property, excellent storage stability, and raw material sources are wide, and production cost is low.But its resistance toheat is poor, the phenomenon of at high temperature can soften, leaking electricity, is therefore mainly used in common heat-resisting rank Production of Enamel Wires.In order to improve the resistance toheat of polyester wire enamel, research institution both domestic and external has carried out a large amount of study on the modification to Polyester Paint, but is applied on a large scale due to the factor such as production cost, production technique.
Summary of the invention
The object of the present invention is to provide a kind of modified polyester wire enamel, production cost is low, has high-solid level, low viscous characteristic, satisfactory mechanical property after film-forming, and has good thermal shock resistance.
Described modified polyester wire enamel, is made up of the raw material of following weight part:
Organic-silicon-modified polyethylene terephthalate 30-40 part, cresols 20-30 part, dimethylbenzene 10-20 part, terephthalic acid 10-15 part, m-phthalic acid 5-10 part, neopentyl glycol 10-20 part, glycerol 12-18 part, dimethyl formamide 10-20 part, N-Methyl pyrrolidone 10-15 part, nano silicon 5-10 part, polyether polyester modified organic silicon oxygen alkane 1-3 part, acrylate 1-5 part, resol 1-2 part, hexanodioic acid 2-5 part.
Preferred modified polyester wire enamel, is made up of the raw material of following weight part:
Organic-silicon-modified polyethylene terephthalate 35 parts, 25 parts, cresols, dimethylbenzene 15 parts, terephthalic acid 12 parts, m-phthalic acid 8 parts, neopentyl glycol 15 parts, glycerol 15 parts, dimethyl formamide 15 parts, N-Methyl pyrrolidone 12 parts, nano silicon 8 parts, 2 parts, polyether polyester modified organic silicon oxygen alkane, acrylate 3 parts, 1.5 parts, resol, hexanodioic acid 3 parts.
Compared with prior art the invention has the beneficial effects as follows:
The present invention reduces solvent usage quantity, effectively solid content is improve while reduction production cost, employ the multi-solvents such as dimethyl formamide, N-Methyl pyrrolidone part simultaneously and replace cresols, greatly reduce the usage quantity of cresols, reduce the pollution to environment.Have good thermotolerance, insulativity, machinery and chemical resistance after modified polyester wire enamel film curing of the present invention, temperature classification can bring up to 220 DEG C from 130 of conventional polyester wire enamel DEG C, and substantially prolongs the work-ing life of product.
