Abstract
The present invention relates to wire enamel and a preparation process thereof, and particularly to non-phenol type polyester wire enamel and a preparation process thereof. A solvent of alcohol ether, such as diethylene glycol ether or dipropylene glycol methyl ether, is used as a solvent of the non-phenol type wire enamel, and after reactions, the solvent is added with additives, such as phenolic resin, enclosed polyisocyanate, etc. The non-phenol type polyester wire enamel produced by the method of the present invention has the advantages of less phenol pollution to the environment, less contradiction between the phenol supply and the phenol demand, less production cost, higher production rate and higher labor productivity.
Description
Technical field
The present invention relates to a kind of wire enamel and production technique, particularly a kind of Non Phenol Type Polyester Wire Enamel And Production Technology.
Background technology
Tradition polyester or modified poly ester wire enamel, generally in the presence of catalyzer such as positive butyl (tetra) titanate or zinc acetate, carrying out esterification or transesterification reaction with diprotic acid or diester and dibasic alcohol and trivalent alcohol, adding phenol solvent after resin reaches certain molecular weight dissolves, dilute with dimethylbenzene or solvent wet goods aromatic hydrocarbons, add positive butyl (tetra) titanate etc. then and make linking agent, filter the back and become wire enamel, its effective ingredient is generally about 25-35%.
Wherein use the sizable phenol solvent of a large amount of toxicity, volatilization or burning cause sizable environmental pollution and the human injury bigger to the Production of Enamel Wires operative employee in the Production of Enamel Wires process.But owing to the excellent dissolution performance of phenol solvent to this type of resin still adopts so far.
Phenol solvent is mainly derived from the coking by-product, and in recent years, country more and more payes attention to environment protection, and some coke-oven plants are closed down, and the phenol solvent source is dwindled.But along with the develop rapidly of electron trade, increasing to the demand of wire enamel, the demand to this phenol solvent is just more simultaneously.
Summary of the invention
The objective of the invention is to propose a kind of can reduce produce in the phenol solvent process and in the Production of Enamel Wires process to the Non Phenol Type Polyester Wire Enamel And Production Technology of the disparities between supply and demand of the dual pollution of environment and phenols.
The object of the present invention is achieved like this: a kind of non-phenol polyester paint for enamel-insulated wire, by (pressing the mol ratio) 1 part of diprotic acid, 0.4-2 part dibasic alcohol, 0.4-1 part trivalent alcohol and 0.2-2 part solvent, solvent is a diethylene glycol ether, and according to producing needs fixed positive butyl (tetra) titanate or zinc acetate catalyst adds dimethylbenzene after reacting or the solvent oil thinner forms, also be added with additive phenolic resin and blocked polyisocyanate after the reaction.
Wherein, diprotic acid refers to terephthalic acid, dimethyl terephthalate (DMT), m-phthalic acid, phthalic anhydride, naphthalic acid, naphthalic anhydride, hexanodioic acid, and contains heat-stable imide diprotic acid etc. by trimellitic acid 1,2-anhydride and diaminodiphenylmethane or diaminodiphenyl oxide synthetic;
Dibasic alcohol refers to ethylene glycol, Diethylene Glycol, triethylene glycol, neopentyl glycol, butyleneglycol, hexylene glycol, 1,4 cyclohexane dimethanol etc.;
Trivalent alcohol refers to glycerine, TriMethylolPropane(TMP), three (2-hydroxyethyl) chlorinated isocyanurates (THEIC) etc.
Resol is 50% the M-and P-cresols and the cresol liquor of formaldehyde condensation products.
Blocked polyisocyanate is 50% tolylene diisocyanate and TriMethylolPropane(TMP) polymers solution.
The technological process of production of non-phenol polyester paint for enamel-insulated wire:
A, diprotic acid, dibasic alcohol, trivalent alcohol and catalyzer dropped into reactor and be warming up to 150 ℃ after, be warming up to 200 ℃-230 ℃ with 8 ℃-10 ℃/hour speed.
B, adding diethylene glycol ether, are cooled to below 80 ℃ after 10-300 minute 160-210 ℃ of insulation;
C, adding diethylene glycol ether, thinner, additive stir;
D, filtration obtain non-phenol polyester paint for enamel-insulated wire.
With the non-phenol polyester paint for enamel-insulated wire that the inventive method is produced, not only reduced the pollution of phenols to environment, alleviated the disparities between supply and demand of phenol solvent, and the reduction of Production of Enamel Wires cost, production rate improves, and has improved labour productivity.
