Abstract
The invention discloses a wet bonding resistant alcohol soluble self-bonded paint and a preparation method thereof. According to the preparation method, p-cresol, dimethylbenzene and butanol are taken as a mixed solvent, ES-08, IC alcohol-soluble nylon and epoxy resin are taken as the main raw materials, and a lubricant is taken as an addition agent. The alcohol-soluble nylon is added into equipment and is dissolved by the mixed solvent into an intermediate semi-finished product, and the epoxy resin and a certain proportion of lubricant are added for modification and reaction so as to obtain the product. As the epoxy resin with high molecular weight, high softening point and good humidity resistance is taken as the cooperative modified resin of the alcohol-soluble nylon, and a proper proportion of a lubricant and the mixed solvent with gradually steady evaporation property are added for cooperation, so that the wet bonding resistance of the enameled wire self-bonded paint is greatly improved; the prepared product has good homogeneity and storage stability; and chemical components of low chemical activity are adopted for cooperation, so that the production requirement of the product in production process is lowered, and the property of the product is more stable.
Description
Technical field
The present invention relates to a kind of enameled wire self-adhesion paint and preparation method thereof, particularly a kind of possess sticking pure soluble self-adhering paint of moisture-resistant and preparation method thereof.
Background technology
Alcohol soluble self-adhering paint is a kind of self-adhesion paint that has the call in the self-binding enamel wire paint, owing to possessing lower alcohols (ethanol, methyl alcohol) dissolving adhesion characteristic, improve the working (machining) efficiency of coil, be widely used in the manufacturing that electroacoustic coil, magnetic card coil, telefault, special purpose micromotor coil etc. have the special electronic wire of (nothing) skeleton.
Usually adopt the nylon (PA) of pure dissolubility as the main film forming material of such self-adhesion paint, then coordinate with resol as the modified resin sintetics.In actual applications, because the molten nylon of alcohol has water absorbability and low-crystalline (hardness is lower), often cause when producing fine dimension wire (≤Φ 0.10mm) at room temperature sticking line (sticking axle), therefore finished wire rod must adopt (≤25 ℃ of harsh conditions of storage, air conditioner dehumidification) store, cause finished wire rod often to glue axle and scrap, quality is very unstable; The high chemically reactive of resol causes that the production technique of product is very narrow, and enameled wire finished product storage period is short.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of pure soluble self-adhering paint that can satisfy the production of wirerods requirement, have the sticking function of moisture-resistant.
The present invention also provide a kind of should the alcohol soluble self-adhering preparation method of paint.
Technical scheme: for solving the problems of the technologies described above, the pure soluble self-adhering paint that a kind of moisture-resistant provided by the invention is sticking, moiety is as follows by weight: 35～44 parts of M-and P-cresols, 35～48 parts, 5～9 parts butanols of dimethylbenzene, 4.4～4.9 parts of molten nylon of ES-08 alcohol, 4.4～4.9 parts of molten nylon of IC alcohol, 1.2～1.8 part of 607 epoxy resin, 1.2～1.8 part of 604 epoxy resin, 0.12～0.15 part of lubrication prescription.
Preferably, described lubrication prescription adopts amine hydroxybenzene.
pure soluble self-adhering paint with the sticking function of moisture-resistant provided by the invention, its step comprises as follows: (1) by weight, take 35～44 parts of M-and P-cresols, 35～48 parts of dimethylbenzene, 5～9 parts, butanols, mix in the reactor of input with agitator, be heated to 45～50 ℃, add 4.4～4.9 parts of molten nylon of ES-08 alcohol, the molten nylon of ES-08 alcohol is attained prestige matrix material company limited by Shanghai and is buied, 4.4～4.9 parts of molten nylon of IC alcohol, the molten nylon of IC alcohol is buied by BASF stock company, stir and be heated to 90～100 ℃, insulation 2.5～3h, until the ES-08 molten nylon of alcohol and the molten nylon of IC alcohol dissolve fully, then be cooled to 50～60 ℃, generate work in-process A,
(2) with 1.2～1.8 part of 607 epoxy resin, 1.2～1.8 part of 604 epoxy resin, put into respectively in the reactor of above-mentioned work in-process A and stir, be incubated 2～3h until 607 epoxy resin and the dissolving of 604 epoxy resin mix at 50～60 ℃ of temperature, generate work in-process B, adopt 607 epoxy resin and 604 epoxy resin of high molecular in this step, because these two kinds of resins are low oxirane value resins, therefore can effectively improve the wet viscosity of finished product, in process of production the conditions permit of producing there is simultaneously the rangeability of certain limit, reduced the requirement to working condition, increased the yield rate of producing.
(3) work in-process B is cooled to 40～45 ℃, adds 0.12～0.15 part of lubrication prescription, and at this temperature insulated and stirred 1～1.5h;
(4) finished product by step (3) preparation adopts 〉=250 purpose filtering nets, makes after filtration product.
Beneficial effect: the present invention is due to the cooperation modified resin of the epoxy resin that has adopted high molecular, high softening-point, good moisture resistance as the molten nylon of alcohol, add the lubrication prescription of proper ratio and have the progressively steadily mixed solvent of evaporation cooperation, greatly improved the sticking characteristic of moisture-resistant of enameled wire self-adhesion paint; Have good intermiscibility between the each component of selecting simultaneously, in conjunction with process matched therewith, make the finished product that makes have good homogeneous and stability in storage; Adopted the lower chemical composition of chemically reactive to coordinate in formula, reduced product in process of production to the requirement of working condition, made simultaneously the performance of product more stable.After testing, the self-adhesion paint that makes according to the inventive method reaches following performance perameter index:
A, outward appearance: as clear as crystal, machinery-free impurity homogeneous liquid;
B, viscosity: 50 ± 10 seconds (T-4 cup/30 ℃);
C, solids content: 12 ± 1%(180 ℃/1g/1h).
The enameled wire moisture-resistant viscosity energy that adopts the present invention to make is good, and use and memory cycle are long, can reduce transportation and carrying cost simultaneously.
