Abstract
The invention discloses a paint dipping process for an amorphous CD type iron core. In the process, E44 epoxy resin, 651 curing agent, acetone and 3131 insulating resin paint are selected as process materials, the formula is optimized, and special processes and steps are adopted. The iron core treated by the paint dipping process has clean appearance, and the original paint nodule scraping process is reduced; the iron core is firm to stick, and diffused sheets are reduced after cutting; and the iron core is not deformed, the condition that the size of the product does not meet the requirement is not caused, and raw material waste can be avoided.
Description
Technical field
The present invention relates to a kind of paint-dipping process of amorphous CD shaped iron core.
Background technology
At present, manufacturer is in amorphous CD shaped iron core is produced, and production technology mode and materials'use that product adopts in iron core curing process, exist following defect: (1), lamination cohere insecure, loose sheet after cutting.Even also there will be jacks to peel off at finished product, affect terminal use and use, peel off fragment and be easy to cause short circuit phenomenon, burn out equipment complete machine, occur heavy losses; (2), solidification internal stress is large, after product cutting, owing to discharging stress, is easy to cause deformation of products, do not meet fitted position, productions in, increases and reprocesses operation, wastes a large amount of raw material that should not waste; (3), solidify after product surface much paint knurl, be difficult to cleaning.The stress producing in scale removal process and this sound of solidified paint all cause product magnetic property to decline.
Summary of the invention
The technical problem to be solved in the present invention is, coheres loose sheet after insecure, cutting for solving, and deformation of products affect the defect of product magnetic property decline, adopts a kind of paint-dipping process technology of novel amorphous CD shaped iron core, to achieve the above object.
Solution of the present invention is: select E44 epoxy resin, 651 curing agent, acetone, 3131 insulating resin paints as process materials, and the optimization on filling a prescription, and adopt following technique to add mode step:
(1), by E44 epoxy resin and 651 curing agent according to the ratio allotment of 1: 0.8 after, add the acetone diluted of 5 times;
(2), by product Dipping 20 minutes in the good solution of above proportioning;
(3), by product take out take out 10 minutes by vacuum, the diluent in product is taken out;
(4), by after product approval, 170 DEG C baking 5 hours, make curing materials completely curing;
(5), will have cured stereotyped product and take out from fixture, product is put into vacuum tank after cooling,
(6), after installing the reach-0.095MPa of vacuum pressure container vacuum-pumping of product, close vacuum valve;
(7), 3131 insulating resin paints are put into infusion product in the vacuum tank of dress product, allow it leave standstill after 10 minutes, add 5KG pressure with dry gas, allow product under pressurized state, soak 60 minutes;
(8), soaked above vacuum pressure product was dripped to paint after 10 minutes, at 165 DEG C, toast 4 hours by the mode that is hung.
The invention has the beneficial effects as follows: first with under the very low allotment paint gelatinization temperature of a kind of concentration, simple product sizing being cohered curing, resin is not just filled full iron core completely like this, can make product be subject to very little stress, product magnetic property is almost constant, then after the product being as above cured being vacuumized, allow the higher paint of a kind of bond strength, the paint infusion product that adhesive force is more intense, interiors of products also can supplement paint enters, and also can hang up paint simultaneously on surface.
Iron core outward appearance by paint-dipping process processing like this is clean, has reduced original scraping and has painted knurl operation; Iron core coheres firmly, seldom occurs loose sheet phenomenon after cutting; Iron core can not be out of shape, and can not cause the undesirable situation of product size, and raw material can avoid waste.
Detailed description of the invention
According to the paint-dipping process of above-described a kind of amorphous CD shaped iron core, select E44 epoxy resin, 651 curing agent, acetone, 3131 insulating resin paints as process materials, the amorphous CD shaped iron core product that adopts aforementioned technique to add mode step to produce, solve completely and cohered insecure, the rear loose sheet of cutting, deformation of products, affects the defect that product magnetic property declines.
