Description of the Invention (1) The present invention relates to a thermosetting perfusion composition for impregnation of power supplies and electronic components. These components are infused with these compositions. The composition recurs and protects the component from mechanical and chemical effects. The epoxy resin-based composition is preferably used in this application section because it has high mechanical strength, excellent chemical stability, and excellent electrical properties. The composition thus includes one or more epoxy resins, hardeners and more than 20 to 70% by weight of fine particle filling seals per molecule. The purpose of these fillers is to improve the hardening composition. Mechanical and chemical properties, and reduce shrinkage during curing. . de-C-32 29 558 has applied to use white ridge as an ideal filler. Eρ · Α · 〇3J ^ 193 and DE-C-42 〇6 7U further disclose that the filler is selected from the group consisting of aluminum hydroxide, hydroxide Magnesium, red phosphorus, dolomite, alumina, hafnium dioxide, Shi Xi_, second acid name (gray stone), finely ground mica or powdered glass, glass frit, glass fiber or glass whisker All these fillers present the same problem. If their particle size is very small, for example, when it is the white barrier of Shen Dian or the oxygen cutting of fine particles, the impregnation ability of the composition will be reduced. Thick, it is easy to settle, especially because the epoxy compound used is low viscosity. This can lead to unevenness of the impregnated layer and cracking under mechanical or thermal stress. Said ... & therefore. It is an object of the present invention to provide a high-quality impregnation infusion composition for power supplies and electronic components. The composition includes epoxy resin as the base grease, which will exhibit a good impregnation effect and provide uniform impregnation. When used in industry, it will provide excellent protection from mechanical and chemical. Infringement: It can also provide high resistance to temperature changes. ----- I --- I ---------- Order --------- (Please read the notes on the back before filling this page) -4-

Non-settling, homogeneous impregnated infusion compositions found to have excellent impregnation and, if included, epoxy resin and hardener as binders, and one or more selected from the group consisting of calcium carbonate or dolomite and hydroxide A filler consisting of seven mixtures of aluminum was prepared as a filler. The composition may also include other conventional additives, such as hardening accelerators, adhesion promoters, reaction net extenders, and modifiers, such as polyether polyols or polyoxanes, wetting agents, and pigments. These compositions are used in a previously known manner to impregnate electrical and electronic components, especially ignition coils. Once the composition has been used for infusion (preferably under Xingxuan) ', it will cure at South temperature. It then forms a homogeneous covering with excellent chemical, mechanical and electrical properties and high resistance to temperature changes. The filler content of the novel composition is based on the total amount of the individual mixtures, and is between 10 and 70% by weight, preferably between 50 and 60% by weight. According to the present invention, these fillers are a mixture of aluminum hydroxide and calcium carbonate or dolomite, or a mixture of carbonic acid office and dolomite in any desired ratio. Here, the proportion of aluminum hydroxide is based on the total amount of the filler, and is 5 to 30, preferably 10 to 20% by weight. The advantages of the novel mixture are not to cut back the need to determine the fineness of the filler, and there will be no negative effects on the impregnation performance or final properties of the cured composition. -5- Paper g + Guan Jia Xian (CNS) A4 Specification (210 x 297 公 爱 1 (Please read the note on the back?

Invention Explanation (3) Impact. This means that it may be possible to use proprietary extremely fine-grained fillers with an average particle size of about 0.1 to 5 microns, such as precipitated or precipitated and hydrophobic chalk. This impregnation ability to the composition will not It has a negative effect. However, it is also possible to use a coarse-grained abrasive filler that has an average particle size between 2 and 60 microns and does not settle in novel blends. The filler can therefore have a particle size between 0.01 and 100 microns in any application. Another advantage of the novel impregnated infusion composition is that there is no urgent requirement for the initial viscosity of the epoxy compound used, so there is no need to provide Specific resin mixture, just follow Basic conditions of low initial viscosity are sufficient. Therefore, it is possible to use commercially available base resins and specific resins required to achieve, for example, a particularly high Tg 値. The decisive factor is that these compounds contain at least two epoxy groups per molecule on average, Viscosity at 25 ° C is less than 20000 mpas. For reasons of cost efficiency, it is better to use suitable commercially available resins based on diglycidyl ether of bisphenols, especially bisphenol A or bisphenol F, and these Need to be used with a diluent. Any known compound for epoxy resin curing can be used as a hardener. It is preferred that it generally does not harden quickly until a specific starting temperature < internal latent epoxy Resin hardeners. Typical examples of these hardeners are (if required) dicarboxylic anhydrides that can be accelerated with imidazoles or alkyl-substituted imidazoles. Other preferred hardeners are novolac resins, especially at temperatures up to 50 c. Novolac resin liquids used at other temperatures, such as those disclosed in 248 980. These hardeners can increase the toughness of the cured impregnated composition.
