Abstract
The invention relates to an organic/inorganic wire enamel and a preparation method thereof. The organic/inorganic wire enamel is mainly prepared by mixing and reacting xylenol, trimellitic anhydride, diaminodiphenyl methane, maleic anhydride, acrylate, glycerol, neopentyl glycol, dimethyl terephthalate, straw ash, titanium tetrabutoxide, attapulgite, N-methylpyrrolidone and additives in certain weight proportion. The preparation method is simple and has the advantage of low cost, and the prepared wire enamel has the advantages of high heat resistance, high solvent resistance and high cold resistance.
Description
Technical field
The present invention relates to a kind of organic-inorganic wire enamel and preparation method thereof, belong to the wire enamel field.
Background technology
Be used to produce enameled wire at present and mainly contain following two kinds with coating:
One type of compound coating that is selected from polyimide or it and other polymkeric substance; Another kind of be selected from polyamidoimide or with the compound coating of other polymkeric substance.
Consider that from production cost the cost of polyimide and polyamidoimide is high, but also will use expensive molten Ji.Consider from material property; Organic-inorganic wire enamel circle is between polyimide enameled wire lacquer and polyester wire enamel; Be to belong to H one 200 class B insulations lacquer; The organic-inorganic wire enamel is superior to polyimide enameled wire lacquer and polyester wire enamel aspect a lot; This is in backbone structure, both to have contained ester group because of being selected from the organic-inorganic wire enamel; Contain heat-stable imide ring again, so this polymkeric substance has combined the ability advantage of polyester and polyimide.The existence of ester group has reduced cost; But also reduced the thermostability of polyester-imide; The boundary is between polyimide and polyester but it still is; Belong to one 200 grades of materials of H; Improved solubility simultaneously; Its processability also is significantly improved, and can process to have excellent mechanical properties and stable on heating wire enamel.Owing to the existence of imide ring, its thermotolerance is better than polyester, and starting material are more cheap than polyimide during department; Oneself is replaced by polyester-imide so external polyester lacquer is basic.
The mode of producing the organic-inorganic wire enamel at present has two kinds, and a kind of is single stage method, and another kind is a two step method.Single stage method is that one-time reaction obtains required polyester imine resin the disposable whole inputs of the starting material of polyester and imines, and then dissolving is made into polyester ware amine wire enamel; Two step method is earlier the starting material that generate polyester to be reacted into her matter of low molecular weight polycaprolactone ester to drop into the starting material that generate imines again, and reaction obtains required polyester imine resin, and same then dissolving is made into the organic-inorganic wire enamel.
Summary of the invention
To above-mentioned deficiency, the object of the present invention is to provide a kind of organic-inorganic wire enamel and preparation method thereof.
The present invention adopts following technical scheme to achieve these goals:

Also be added with additive in the composition of described organic-inorganic wire enamel, its quality is the 1-3% of total solids raw material weight.
The preparation method of described organic-inorganic wire enamel is characterized in that may further comprise the steps:
(1) trimellitic acid 1,2-anhydride, MALEIC ANHYDRIDE, dimethyl terephthalate (DMT) and acrylate are pressed in the weight part adding reaction kettle of constitutive material, be heated to 150-200 ℃, reacted 4.5-5.5 hour;
(2) solution that obtains in step (1) adds two amido ditanes by weight, keeps 155-180 ℃, is incubated half an hour;
(3) in the solution that step (2) obtains, add neopentyl glycol, glycerine, be warming up to 180-210 ℃, reacted 30-60 minute, vacuumize, phenol solvent is extracted in decompression out;
(4) in the solution that step (3) obtains, add N-Methyl pyrrolidone, stalk ashes, tetrabutyl oxygen titanium, attapulgite successively, control reaction temperature is reacted half hour at 160-170 ℃;
(5) in the solution that step (4) obtains, add xylenol and additive, stir paint.
Described organic-inorganic wire enamel is characterized in that: described additive is selected from least a in resol or the aminoresin.
