Description
Technical field
The present invention relates to a kind of epoxy resin spraying method, particularly to a kind of amorphous nano-crystalline iron core spray epoxy method.
Background technology
Little iron core packaging is generally adopted two kinds of manner of packings: one, protect box packaging. This manner of packing waste of manpower, raw material, production cost is high, improves product price. And it is high to introduce cost when reprocessing. This manner of packing is unfavorable for producing on the whole. Two, spraying packaging. Existing spraying manner of packing includes spray epoxy, spray coating powder paint etc.
Existing epoxy resin spraying method many employings pressure air sprays. When spraying amorphous nano-crystalline iron core by the method merely, adhesion of epoxy resin degree is less, and after spraying, iron core hydraulic performance decline is more, is difficult to obtain the amorphous nano-crystalline iron core that performance is qualified.
Summary of the invention
Spray little iron core for realizing epoxy resin, it is an object of the invention to provide a kind of spraying effect good, save the time, the epoxy resin spray coating liquor reducing cost and the method utilizing this epoxy resin spray coating liquor to carry out epoxy resin spraying. Pressure air spray epoxy need to being improved, namely before spraying, little iron core to toast, and adopts the proportioning that this patent draws when joining glue.
A kind of epoxy resin spray coating liquor provided by the present invention, is made up of the component of following portions by weight ratio:
Epoxy resin 100 weight portion,
Firming agent 30 weight portion,
Dimethylbenzene 10-30 weight portion.
Described firming agent is the phenolic aldehyde amine epoxy curing agent meeting HG/T3875-2006.
Described epoxy resin is preferably the bisphenol A type epoxy resin meeting GB/T13657 1992.
A kind of epoxy resin spraying method provided by the invention, comprises the steps:
1) one side of matrix to be sprayed is sprayed the epoxy resin spray coating liquor described in any one in claim 1-3;
2) by the matrix after spraying at 100 DEG C 120 DEG C baking time 15min 30min;
3) by step 2) baking after matrix turn-over after according to step 1)-2) and method spraying another side.
Preferably, described in step 2) terminate after, repeat step 1) and step 2) 4-5 time, it is preferable that 4 times; Described step 3) terminate after, repeat step 3) 3-5 time, it is preferable that 3 times.
Preferably, described step 1) in also include, in spraying claim 1-3 before epoxy resin spray coating liquor described in any one, matrix to be sprayed is toasted 15min 30min at 100 DEG C 120 DEG C.
In a technical scheme of the present invention, described matrix to be sprayed is amorphous iron core.
The useful technique effect of the present invention: the present invention have passed through one or many spraying process, prepares epoxy coating at matrix surface; Coating after-baking procedure of processing. The present invention is by adopting the spray coating liquor spray epoxy layer of the present invention, it is possible to spray epoxy layer on such as amorphous nano-crystalline iron core matrix.
Original amorphous nano-crystalline iron core adopts and protects box packaging, not only waste material but also take a lot of work and client uses and can waste copper cash. Reduced the packing cost of amorphous nano-crystalline iron core by spray epoxy technology, accelerate the packing processes time of amorphous nano-crystalline iron core.
It addition, present invention optimizes the proportioning of the technique of spraying and spray coating liquor, improve the performance after the spray epoxy of amorphous nano-crystalline iron core.
