Abstract

The invention discloses sticky alcohol soluble self-adhering paint of a kind of moisture-resistant and preparation method thereof, the method adopts M-and P-cresols, dimethylbenzene, butanols as mixed solvent, and the molten nylon of ES-08, IC alcohol, epoxy resin is as main raw material, and coordinating with lubrication prescription is that auxiliary agent forms.Add the molten nylon of alcohol in a device to dissolve as intermediate semi-finished products using mixed solvent, then add epoxy resin and certain proportion lubricant gives modification, further reaction cost product.The present invention due to have employed high molecular, high softening-point, good moisture resistance epoxy resin as the cooperation modified resin of the molten nylon of alcohol, the lubrication prescription of adding proper ratio and the mixed solvent with progressively steadily evaporation coordinate, and the moisture-resistant significantly improving enameled wire self-adhesion paint glues characteristic; Make the finished product obtained have good homogeneous and stability in storage simultaneously; Have employed the lower chemical composition of chemically reactive in formula to coordinate, reduce product in process of production to the requirement of working condition, make the performance of product more stable simultaneously.

Description

Alcohol soluble self-adhering paint that a kind of moisture-resistant is sticky and preparation method thereof
Technical field
The present invention relates to a kind of enameled wire self-adhesion paint and preparation method thereof, particularly a kind of possess sticky alcohol 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 had the call in self-binding enamel wire paint, adhesion characteristic is dissolved owing to possessing lower alcohols (ethanol, methyl alcohol), improve the working (machining) efficiency of coil, be widely used in the manufacture there is (no) the special electronic wire of skeleton such as electroacoustic coil, magnetic card coil, telefault, special purpose micromotor coil.
The nylon (PA) of usual employing alcohol dissolubility as the main film forming material of such self-adhesion paint, then coordinates using resol as modified resin sintetics.In actual applications, because the molten nylon of alcohol has water absorbability and low-crystalline (hardness is lower), often cause (≤Φ 0.10mm) at room temperature sticky line (sticky axle) when producing fine dimension wire, therefore finished wire rod must adopt harsh condition of storage (≤25 DEG C, air conditioner dehumidification) store, cause finished wire rod often to glue axle to scrap, quality is very unstable; The high chemically reactive of resol, cause the production technique of product very narrow, enameled wire finished product storage period is short.
Summary of the invention

Present invention also offers a kind of preparation method of this alcohol soluble self-adhering paint.
Technical scheme: for solving the problems of the technologies described above, the alcohol soluble self-adhering paint that a kind of moisture-resistant provided by the invention is sticky, moiety is as follows by weight: M-and P-cresols 35 ~ 44 parts, dimethylbenzene 35 ~ 48 parts, 5 ~ 9 parts of butanols, 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.
Provided by the invention have the alcohol soluble self-adhering paint that moisture-resistant glues function, its step comprises as follows: (1) by weight, take M-and P-cresols 35 ~ 44 parts, dimethylbenzene 35 ~ 48 parts, 5 ~ 9 parts, butanols, drop into and be uniformly mixed with in the reactor of agitator, be heated to 45 ~ 50 DEG C, add 4.4 ~ 4.9 parts of molten nylon of ES-08 alcohol, the molten nylon of ES-08 alcohol is buied by Shanghai Zhen Wei matrix material company limited, 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 DEG C, insulation 2.5 ~ 3h, until the molten nylon of ES-08 alcohol and the molten nylon of IC alcohol dissolve completely, then 50 ~ 60 DEG C are cooled to, generate work in-process A,
(2) by 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, 2 ~ 3h is incubated until 607 epoxy resin and the dissolving of 604 epoxy resin mix at 50 ~ 60 DEG C 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 the wet viscosity of finished product can effectively be improved, in process of production the conditions permit of producing is had to the rangeability of certain limit simultaneously, reduce the requirement to working condition, add the yield rate of production.
(3) work in-process B is cooled to 40 ~ 45 DEG C, adds 0.12 ~ 0.15 part of lubrication prescription, and insulated and stirred 1 ~ 1.5h at this temperature;
(4) finished product prepared by step (3) adopts >=250 object filtering nets, after filtration obtained product.
Beneficial effect: the present invention due to have employed high molecular, high softening-point, good moisture resistance epoxy resin as the cooperation modified resin of the molten nylon of alcohol, the lubrication prescription of adding proper ratio and the mixed solvent with progressively steadily evaporation coordinate, and the moisture-resistant significantly improving enameled wire self-adhesion paint glues characteristic; Between each component simultaneously selected, there is good intermiscibility, in conjunction with process matched therewith, make the finished product obtained have good homogeneous and stability in storage; Have employed the lower chemical composition of chemically reactive in formula to coordinate, reduce product in process of production to the requirement of working condition, make the performance of product more stable simultaneously.After testing, obtained according to the inventive method self-adhesion paint reaches following performance perameter index:
A, outward appearance: as clear as crystal, mechanical impurity homogeneous liquid;
B, viscosity: 50 ± 10 seconds (T-4 cup/30 DEG C);
