Abstract
The invention discloses a durable paint for enameled wire surface. The durable paint includes the following raw materials by weight: 12-27 parts of styrene, 100-110 parts of dimethyl terephthalate, 35-50 parts of propylene glycol, 40-70 parts of xylenol, 50-55 parts of trimellitic anhydride, 42-60 parts of glycerin, 30-40 parts of acrylic ester, 15-30 parts of polydodecalactam, 20-30 parts of mica powder, 1-3 parts of attapulgite, 60-85 parts of 3'-dimethyl diphenylmethane, and 18-33 parts of N-methylpyrrolidone. The invention increases the molten fluidity of resin, improves the coating performance of enameled wire, can easily get a good enameled wire surface; the pinhole performance of the paint film is improved, and the tensile strength of the surface paint layer of the enamelled wire; the paint layer of the enameled wire prepared by using the paint is difficult to break for a long term, so as to ensure the performance of the enameled wire.
Description
Technical field
The present invention relates to a kind of durable paint for enamelled wire surface.
Background technology
Japanning is process wire enamel coated being formed with on metallic conductor certain thickness even enamelled coating.Anneal before the japanning of metallic conductor outside surface in prior art, annealing makes softening being convenient to of wire paint, owing to not testing the tensile strength of enamelled coating when being and first annealing post coat, japanning, when the tensile strength of enamelled coating generally causes wire enamel unwrapping wire in prior art or the long-time enamelled coating that uses to break, affect the properties of enameled wire.
Summary of the invention
When the object of the invention is to solve wire enamel unwrapping wire in prior art or the long-time enamelled coating that uses to break, affect the problem of properties of enameled wire.
The technical solution used in the present invention is: for the durable paint of enamelled wire surface, raw material comprises by weight: vinylbenzene 12-27 part, dimethyl terephthalate (DMT) 100-110 part, propylene glycol 35-50 part, xylenol 40-70 part, trimellitic acid 1,2-anhydride 50-55 part, glycerine 42-60 part, acrylate 30-40 part, nylon 12 15-30 part, mica powder 20-30 part, attapulgite 1-3 part, 3 '-dimethyl diphenyl methane 60-85 part, N-Methyl pyrrolidone 18-33 part.
The invention has the beneficial effects as follows: after have employed the present invention, add the melt fluidity of resin, improve the coated performance of enameled wire and easily obtain good enamelled wire surface, improve the pin hole performance of paint film, enamelled wire surface enamelled coating pull resistance is strong, adopting this wire enamel to be coated with the enameled wire produced uses enamelled coating not easily to break for a long time, ensures the properties of enameled wire.
Embodiment
The present invention is described further below.
For the durable paint of enamelled wire surface, raw material comprises by weight: vinylbenzene 12-27 part, dimethyl terephthalate (DMT) 100-110 part, propylene glycol 35-50 part, xylenol 40-70 part, trimellitic acid 1,2-anhydride 50-55 part, glycerine 42-60 part, acrylate 30-40 part, nylon 12 15-30 part, mica powder 20-30 part, attapulgite 1-3 part, 3 '-dimethyl diphenyl methane 60-85 part, N-Methyl pyrrolidone 18-33 part.
Making step:
Step (1): take vinylbenzene, trimellitic acid 1,2-anhydride drops into and is uniformly mixed with in the reactor of agitator, be heated to 35-45 DEG C, add nylon 12, stir and be heated to 150-200 DEG C, reaction 4.5-5.5 hour, then add acrylate, mica powder, insulation 3-5 hour;
Step (2): step (1) reaction mass is cooled to 60-80 DEG C, adds 3 '-dimethyl diphenyl methane, dimethyl terephthalate (DMT), keeps temperature, stirring reaction 1-3 hour;
Step (3): add propylene glycol, glycerine in the solution that step (2) obtains, be warming up to 180-210 DEG C, reaction 30-60 minute, vacuumizes, and phenol solvent is extracted in decompression out;
Step (4): add N-Methyl pyrrolidone, attapulgite successively in the solution that step (3) obtains, controls temperature of reaction at 160-170 DEG C, reaction half hour;
Step (5): add xylenol in the solution that step (4) obtains, stirs paint.
Those skilled in the art should know; protection scheme of the present invention is not limited only to the above embodiments; various permutation and combination and conversion can also be carried out on the basis of above-described embodiment; under the prerequisite without prejudice to spirit of the present invention, the various conversion that the present invention carries out all are dropped in protection scope of the present invention.
