Abstract
The application relates to the technical field of wire insulation, in particular to wire insulation glue and a preparation method thereof, wherein the common technical key points of the two schemes are as follows: the paint is prepared by mixing the following components in percentage by weight: 15% -99% of rosin resin; 1-60% of ethylene-vinyl acetate copolymer. The rosin resin has the functions of insulation and welding assistance, the ethylene-vinyl acetate copolymer has the functions of insulation, tackifying, reinforcing and softening, the exposed lead is wrapped by the compound formed by mixing the rosin resin and the ethylene-vinyl acetate copolymer, so that the lead can be insulated, and can be melted by direct spot welding without removing glue during processing.
Description
Technical Field
The application relates to the technical field of wire insulation, in particular to wire insulation glue and a preparation method of the insulation glue.
Background
In the battery industry, particularly in the process of transporting batteries connected with leads, the exposed leads are wrapped by high-temperature glue or plastic sleeves at present, so that the leads are prevented from bumping in the transportation process and further from friction short circuit, and the dangerous accidents caused by spontaneous combustion of the batteries are prevented; although the two modes can prevent the wire from contacting and avoid the spontaneous combustion of the battery, after the wire wrapped by the high-temperature rubber or the plastic sleeve is transported to a destination, the wire is insulated due to the high-temperature rubber and the plastic sleeve, and workers need to carry out the step of removing the rubber or the sleeve so as to facilitate subsequent processing and production, so that the processing steps are not only complicated, but also the production cost is increased and the production efficiency is reduced.
Content of application
The utility model provides a to the not enough of above-mentioned prior art, the first purpose of this application is to provide a wire insulating cement, not only can make the wire insulating, need not to go to glue moreover during processing, has improved production efficiency.
The first purpose of the application is realized by the following technical scheme: a wire insulating cement is prepared by mixing the following components in percentage by weight:
15 to 99 percent of rosin resin
1-60% of ethylene-vinyl acetate copolymer.
Preferably, the composition is prepared by mixing the following components in percentage by weight:
rosin resin 90%
10% of ethylene-vinyl acetate copolymer.
In view of the above-mentioned deficiencies of the prior art, a second object of the present application is to provide a method for preparing a wire insulating paste, which can insulate a wire, and can improve the production efficiency without removing the paste during processing.
The second purpose of the application is realized by the following technical scheme: a preparation method of wire insulating cement comprises weighing rosin resin and ethylene-vinyl acetate copolymer according to formula ratio, mixing, and placing into a heating vessel;
heating to 80-160 deg.c and stirring for further use.
Preferably, the heating temperature is 140 ℃.
To sum up, the beneficial effect that this application has: the rosin resin has the functions of insulation and welding assistance, the ethylene-vinyl acetate copolymer has the functions of insulation, tackifying, reinforcing and softening, the exposed lead is wrapped by the compound formed by mixing the rosin resin and the ethylene-vinyl acetate copolymer, so that the lead can be insulated, and can be melted by direct spot welding without removing glue during processing.
Detailed Description
The first embodiment is as follows: a wire insulating cement is prepared by mixing the following components in percentage by weight:
15 to 99 percent of rosin resin
1-60% of ethylene-vinyl acetate copolymer.
The rosin resin has the functions of insulation and welding assistance, the ethylene-vinyl acetate copolymer has the functions of insulation, tackifying, reinforcing and softening, the exposed lead is wrapped by the compound formed by mixing the rosin resin and the ethylene-vinyl acetate copolymer, so that the lead can be insulated, and can be melted by direct spot welding without removing glue during processing.
In the embodiment, the paint is prepared by mixing the following components in percentage by weight:
90 percent of rosin resin and 10 percent of ethylene-vinyl acetate copolymer.
Of course, according to the actual situation, the rosin resin can be replaced by terpene resin processed by turpentine.
Example two: a preparation method of wire insulating cement comprises weighing rosin resin and ethylene-vinyl acetate copolymer according to formula ratio, mixing, and placing into a heating vessel;
heating to 80-160 deg.c and stirring for further use.
In this embodiment, the heating temperature is 140 ℃, then the wire end of the product to be insulated is immersed in the insulating glue for 0.5 to 3 seconds and then slowly removed, and finally the product is cooled in an environment below 25 ℃ for 1 to 5 seconds.
The above-mentioned embodiments are merely illustrative and not restrictive, and those skilled in the art can make modifications to the embodiments without inventive contribution as required after reading the present specification, but only protected by the patent laws within the scope of the claims of the present application.
