Embodiment Construction

[0014] Capacitor impregnating materials for energy-saving lamps, including epoxy resin, with epoxy resin as the base of mass percentage, and the rest of the ingredients are as follows:

[0015] 5300 defoamer 0.1~0.15%,

[0016] 6500 defoamer 0.1~0.15%,

[0017] 351 chrome glass powder 4~6%,

[0018] Silica powder 60-70%,

[0019] Silica 2-3%,

[0020] Curing agent 20-25%, the curing agent is fatty polyamine, polyethylene polyamine or trimethylhexamethylenediamine;

[0021] Styrene 20-30%.

[0022] Using the above impregnating materials for impregnation treatment, the effect of improving the appearance of the product is obvious (the following percentages are the probability of defects for each certain number of batches, taking 10,000 pieces / batch as an example):

Abstract

The invention discloses a dipping material for a capacitor of an energy-saving lamp, comprising epoxy resin. Based on the weight percent of the epoxy resin, the dipping material comprises the following other components by weight percent: 0.1-0.15 percent of 5300 defoamer, 0.1-0.15 percent of 6500 defoamer, 4-6 percent of 351 chromium-glass powder, 60-70 percent of silica micropowder, 2-3 percent of silicon dioxide, 20-25 percent of curing agent and 20-30 percent of styrene. The invention greatly improves the reliability of the production and prolongs the service life of the product. The surface of the product is smooth and flat, and surface bubbles are basically eliminated. The encapsulation leakproofness of the appearance of the product is good, the exposure phenomenon is thoroughly avoided, and residue is not easily generated on a lead. The insulating resistance of the product is greatly improved at high temperature, and the quality of the capacitor is improved.

Description

technical field [0001] The present invention relates to impregnation materials used in capacitor impregnation processes. Background technique [0002] In the production process of capacitors, the capacitors are impregnated under strict vacuum to improve the appearance quality of capacitors and the reliability and service life of capacitors. The impregnation materials currently used in impregnation treatment include epoxy resin, with epoxy resin as the base of mass percentage, and the remaining ingredients are: 351 chrome glass powder 8-10%, silicon micropowder 25-35%, silicon dioxide 5- 7%, curing agent 30-35%, styrene 30-35%. Using the above impregnating material, air bubbles are likely to be generated on the surface of the capacitor, and the flatness is poor, resulting in poor tightness when the appearance is encapsulated, and whitening phenomenon occurs, which affects the reliability and service life of the capacitor. Contents of the invention [0003] The purpose of ...
