1Epoxy resin insulation materialIntroduction
Epoxy board is made by impregnating electrical glass cloth with epoxy resin, drying, and hot pressing.
Epoxy resin refers to organic polymer compounds containing two or more epoxy groups in their molecules, and except for a few, their relative molecular weight is not high.
The molecular structure of epoxy resin is characterized by the presence of active epoxy groups in the molecular chain, which can be located at the end, middle, or in a cyclic structure of the molecular chain.
IIEpoxy resin insulation materialfeature
1. The surface of the epoxy board is required to be flat, without bubbles, pits, and wrinkles, but other defects that do not affect its use are allowed, such as scratches, indentations, stains, and a small amount of spots. The edges should be cut neatly, and there should be no layering or cracks on the end face.
2. Execution standard: GB/T1303.1-1998 (natural color), red, green, and black are protocol standards.
3. Temperature resistance level: B-grade Color: natural color (yellow), red, green, black, etc. (can be colored and blended into multiple colors).
4. Characteristics: The cured epoxy resin system has excellent mechanical properties, high mechanical strength at medium temperatures, and good electrical stability under high humidity.
5. Electrical properties: The cured epoxy resin system is an excellent insulation material with high dielectric properties, surface leakage resistance, and arc resistance. Usage: for mechanical, electronic, and electrical purposes. Suitable for fields such as mechanical, electrical, electronic, and electrical appliances. Also used for the processing of insulation components, processed into various types of insulation accessories. Equipment insulation structural components.
6. Thickness: Under normal circumstances, it is 0.5-50mm, and thick plates up to 50-150mm can also be produced as required.
3、 Technical parameters
1. The appearance surface should be smooth, without bubbles, wrinkles, and cracks.
2. The nominal thickness and allowable deviation are shown in Table 1.
