Its advantage is that the production process is simple, but the curing time required for curing is long, and the baking time of some products needs to be as long as 5 to 6 hours. In the process of mass production, it will consume a lot of valuable production time and increase manpower and material resources. cost

Embodiment 1
[0017] The spray glue preparation method of the present embodiment may further comprise the steps:
[0018] (1) Fully mix 10 parts of 7001A red glue and 2.5 parts of 7001A white glue in proportion;
[0019] (2) Pour 2.5 parts of 7001B glue into the mixed glue in step (1) and stir well;
[0020] (3) Pour 3 parts of xylene into the mixed glue in step (2) and stir well, the above is by weight.
[0021] The prepared spraying glue is applied to the magnetic core spraying process, which specifically includes the following steps:
[0022] (1) Bake the magnetic core in an oven at 100°C for 5 minutes and then dry it, then place the magnetic core on a spraying table equipped with circulating water, pour the prepared mixed glue into the spray gun, and adjust the space connected to the spray gun. The air outlet speed of the press controls the glue output of the spray gun, so that the sprayed glue is fine and can be sprayed evenly on the magnetic core to meet the smooth and smooth surfac...
Embodiment 2
[0026] The preparation method of spraying glue of the present embodiment comprises the following steps:
[0027] (1) Fully stir 6 parts of 7001A red glue and 3.5 parts of 7001A white glue in proportion;
[0028] (2) Pour 3.5 parts of 7001B glue into the mixed glue in step (1) and stir well;
[0029] (3) Pour 4 parts of xylene into the mixed glue in step (2) and stir well, the above is by weight.
[0030] Other implementations are the same as in Example 1.
Embodiment 3
[0032] The preparation method of spraying glue of the present embodiment comprises the following steps:
[0033] (1) Fully mix 7 parts of 7001A red glue and 3 parts of 7001A white glue in proportion;
[0034] (2) Pour 3 parts of 7001B glue into the mixed glue in step (1) and stir well;
[0035] (3) Pour 3.5 parts of xylene into the mixed glue in step (2) and stir well, the above is by weight.
[0036] Other implementations are the same as in Example 1.

Abstract
The invention discloses spraying glue, a preparation method and applications thereof. The spraying glue includes, by weight, 6-10 parts of 7001A red glue, 2.5-3.5 parts of 7001A white glue, 2.5-3.5 parts of 7001B glue and 3-4 parts of dimethylbenzene. The spraying glue is applied to a magnetic core spraying process. According to the spraying glue, the preparation method and the applications thereof, the defects that in prior curing technology, time-consuming of glue curing and baking is long and a good curing effect can not be obtained in a short time are overcome, raw materials used in the glue formula are easy to purchase, the proportioning process is simple, during a curing spraying process, baking time for pre-curing and curing can be remarkably reduced, the curing effect is improved, besides, the glue is applied to the magnetic core spraying process, sprayed products are not required to be protected by a protective box or other protective devices, the sprayed products can be directly packaged by big boxes one by one, and manpower and material resources required in sequential production processes of magnetic core product are saved.
Description
technical field [0001] The present invention relates to a kind of glue and its preparation and application, in particular to a process of applying glue spraying to magnetic core spraying. Background technique [0002] At present, the magnetic core curing technology is to use ordinary melamine paint, melamine formaldehyde resin, etc. through impregnation and baking processes, so as to improve the hardness and shock resistance of the magnetic core, and improve the stability of the voltage and inductance of the magnetic core product. Several commonly used thermosetting varieties include pure epoxy, epoxy-polyester, pure polyester, acrylic acid, polyurethane, etc., and the methods of use are mostly electrostatic spraying and fluidized bed invasion coating. The curing glue used is basically a single-component epoxy resin binder. Under the condition of heating and baking, a chemical cross-linking reaction occurs to obtain a good curing effect. After curing, a plastic or aluminum p...
