Abstract
The invention discloses one kind can scolding tin wire enamel, it includes glycerol 2000-2200g, ethylene glycol 2400-2500 g, M-and P-cresols 450-500g, dimethylbenzene 450-500g, M-phthalic acid 700-750 g, terephthalic acid (TPA) 3000-3500 g.The advantage of the invention is that, due to reasonable selection various composition formula and define the ratio of various composition formula, in addition, it is added especially in manufacturing process by substep and matching is optimized to technique, especially to the heating and cooling control process of temperature, so that the wire enamel prepared, it is not only able to meet scolding tin performance requirement, with good soldering performance, and product quality effectively improves, and effect is very prominent.
Description
Technical field
The present invention relates to a kind of wire enamel production technologies, and specifically one kind can scolding tin polyester wire enamel and its system
Make method.
Background technique
Enameled wire is mainly used as winding coil, and effect is to realize that " electricity-magnetic " energy turns during component work
It changes, so enameled wire is also electromagnetic wire.The effect of wire enamel be make in winding to generate between conducting wire and conducting wire one layer it is good
Insulating layer, to prevent the circulation of electric current.Wire enamel belongs to electric insulation paint, in addition to requiring good dielectricity, chemistry
Outside performance, it is necessary to which there is excellent mechanical performance and hot property.With industrial electrical equipment, household electrical appliance, telecommunication, electronic product etc.
Rapid development, enameled wire market demand sharply expanded in recent years, this brings broader application to enameled wire industry and leads
Domain and market.
Currently used wire enamel type has acetal, polyurethane, polyester, polyester-imide, polyamidoimide, polyester-
Amide imines etc..However, for existing polyester wire enamel, due to the limitation of its products material and production method, one
As all do not have tin-welding, in addition, it is poor there is also quality the problems such as.
Summary of the invention
That the technical problem to be solved in the present invention is to provide a kind of scolding tin performances is good, product quality is high can scolding tin Polyester Paint packet
Line paint and preparation method thereof.
In order to solve the above-mentioned technical problem, it is of the invention can scolding tin paint polyester enamel, including glycerol 2000-2200g, second
Glycol 2400-2500 g, M-and P-cresols 880-900g, dimethylbenzene 1030-1100g, M-phthalic acid 700-750 g, to benzene two
Formic acid 3000-3500 g, dimethylformamide 350-370g.
A kind of production method of such as above-mentioned solderable tin polyester wire enamel, specific steps are as follows:
A, glycerol 2000-2200g, ethylene glycol 2400-2500 g, M-and P-cresols 450- is added under normal temperature condition into reaction kettle
500g, dimethylbenzene 450-500g, M-phthalic acid 700-750 g, terephthalic acid (TPA) 3000-3500 g then heat to 50-70
DEG C, it is kept for temperature 1-3 hours, then heats to 130-150 DEG C；
B, by 5-7 hours, it then was warming up to 200-250 DEG C using 14-16 hours, it is transparent to product in reaction kettle；
C, M-and P-cresols 430-470 g, dimethylformamide 350-370g, dimethylbenzene 580-600 g are finally added.
After above-mentioned formula and method, due to reasonable selection various composition formula and define that various composition is matched
The ratio of side, in addition, being added especially in manufacturing process by substep and optimizing matching to technique, especially to temperature
Heating and cooling control process have good so that the wire enamel prepared, is not only able to meet scolding tin performance requirement
Soldering performance, and product quality effectively improves, and effect is very prominent.
