Abstract
The present invention is a kind of new polyester imide resin of making wire enamel and preparation method thereof that is used for, and this resin comprises rosin at least, cis-butenedioic anhydride, diisocyanates or two amines, and glycerine or TriMethylolPropane(TMP), glycol component is made through the reaction copolymerization.The raw material of resin of the present invention is easy to get, inexpensive, the method of making this resin is easy, easy to utilize, the wire enamel with resin of the present invention is made can satisfy F, the requirement of H level enameled wire, can make the refrigerant enameled wire and use, through testing identity, every index of enameled wire all can meet or exceed the requirement of IEC317-8 standard.
Description
The present invention relates to a kind of new polyester imide resin and manufacture method thereof of making insulation compound.
Make the enameled wire polyester imine resin in the prior art, be mostly earlier to make the imines diacid, and then form with dimethyl terephthalate (DMT), glycerine copolymerization with two amine materials such as trimellitic acid 1,2-anhydride and diaminodiphenyl oxide or diphenylmethane diisocyanate.Owing to adopt trimellitic acid 1,2-anhydride in its composition, a large amount of use of the high inconvenience of its cost.
The purpose of this invention is to provide component of a kind of new polyester imide resin and preparation method thereof, promptly replace the trimellitic acid 1,2-anhydride composition and make polyester imine resin, overcome defective of the prior art with this with cheap rosin composition.
Purpose of the present invention can realize by following proposal.
The new polyester imide resin comprises (a) rosin at least, (b) cis-butenedioic anhydride, and (c) diisocyanates or two amines, (d) dimethyl terephthalate (DMT), (e) glycerine or TriMethylolPropane(TMP), (f) ethylene glycol or dihydroxyphenyl propane composition are made through the reaction copolymerization.
The proportioning of each composition is: (unit: gram molecular weight)
(a) rosin 1;
(b) cis-butenedioic anhydride 1;
(c) diisocyanates or two amines 0.5;
(d) dimethyl terephthalate (DMT) 2-6;
(e) glycerine or TriMethylolPropane(TMP) 1-3;
(f) ethylene glycol 3-10.
Preparation new polyester imide resin, can realize by following processing step:
(a) with rosin and cis-butenedioic anhydride ratio according to 1: 1 gram molecular weight, stir after putting into the reactor fusion, insulation is 3 hours between 170-200 ℃;
(b) add diisocyanates or two amine compositions in a small amount of cresols solvent, reaction is 2 hours under 170-200 ℃ of condition, generates the imines diacid;
(c) add glycerine or TriMethylolPropane(TMP), ethylene glycol and dimethyl terephthalate (DMT) and little acetic acid zinc make it carry out transesterify and esterification, and in 7 hours, temperature is increased to 230 ℃ gradually, and is incubated 4 hours, and the bunching that reduces pressure is then made resin.
It is to be synthetic a kind of three sour single acid anhydrides and axle thing that the present invention adopts rosin and cis-butenedioic anhydride, thereby can replace trimellitic acid 1,2-anhydride, and utilizing also, the axle thing promptly can be made into the imines diacid with diisocyanates or the reaction of two amines again.In addition to the above methods, also can be with cis-butenedioic anhydride elder generation and diisocyanates or the reaction of two amines, behind the generation imines, the imines diacid is made in reaction with rosin again.
The wire enamel that utilizes new polyester imide resin solubilizing agent cresols of the present invention and other composition to make can satisfy the requirement of F, H level enameled wire, and have cold-resistant matchmaker's property, can make the refrigerant enameled wire and use.Through testing identity, every index of enameled wire all meets or exceeds the IEC317-8 standard-required.Simultaneously, the raw material of resin of the present invention is easy to get, and cost can reduce by 1/3, and makes easy, the easy row of method of this resin, and is easy to utilize.
Below in conjunction with embodiment the present invention is described in detail.
160 gram rosin inputs are had in 200 milliliters of there-necked flasks of stirring, condensation and thermometer, and heat temperature raising to 140 ℃ begins after the rosin fusion to stir, and adds cis-butenedioic anhydrides 53.3 grams to 170 ℃, makes 200 ℃ of following insulation reaction to generate in 3 hours and the axle thing.It is standby that can emit cooling this moment, or continue to drop into cresols 70 grams, when temperature is 170 ℃, add toluene-2,4-diisocyanate 47.5 grams, 190 ℃ of insulations 2 hours, to bubble after a little while, add glycerine 83.2 grams, ethylene glycol 170 grams and dimethyl terephthalate (DMT) 357.5 grams, and catalyst acetic acid zinc 0.3 gram are warming up to 185 ℃, and the control cut steams too not fast, continue to be warmed up to 200-225 ℃ (7 hours times spent approximately), then, be incubated 4 hours under the temperature outside.Open vacuum pump decompression polycondensation, it is 720mmHg that vacuum tightness increases to gauge pressure gradually, and temperature remains on 225 ℃, and about 2-3 hour, when the material viscosity increase, cut reduced, and gets final product stopped reaction, finishes the preparation of resin.During the system lacquer, in resin, add solvent cresols 409 grams, stir half an hour, add cresols and dimethylbenzene ratio again and be 1: 1 mixed solution 600 grams, stir and tremble half an hour, the last mixed solution that adds cresols and each 300 gram of dimethylbenzene and positive butyl (tetra) titanate 47 grams again, stirring half an hour is lacquering, barrelling is standby after filtration.
The new polyester imide resin also can be by following formulation: (unit: gram)
1 2 3 4
(a) rosin cis-butenedioic anhydride and axle thing 356 120 200 280
(b) toluene-2,4-diisocyanate 79.2 26.7 44.5 62.3
(c) glycerine 83.2 86 90 75
(d) ethylene glycol 170 180 300 280
(e) dimethyl terephthalate (DMT) 357.5 357.5 357.5 357.5
(f) dihydroxyphenyl propane 90
