1、是两种不同的类型:环氧树脂是泛指分子中含有两个或两个以上环氧基团的有机化合物,除个别外,它们的相对分子质量都不高。环氧树脂的分子结构是以分子链中含有活泼的环氧基团为其特征,环氧基团可以位于分子链的末端、中间或成环状结构。由于分子结构中含有活泼的环氧基团,使它们可与多种类型的固化剂发生交联反应而形成不溶的具有三向网状结构的高聚物。凡分子结构中含有环氧基团的高分子化合物统称为环氧树脂。
1. There are two different types: epoxy resin generally refers to organic compounds with two or more epoxy groups in their molecules. Except for some, their relative molecular weight is not high. The molecular structure of epoxy resin is characterized by the active epoxy group in the molecular chain. The epoxy group can be located at the end, middle or ring structure of the molecular chain. Because the molecular structure contains active epoxy groups, they can react with various types of curing agents to form insoluble polymers with three-dimensional network structure. High molecular compounds containing epoxy groups in their molecular structures are collectively referred to as epoxy resins.
2、玻璃纤维是一种性能优异的无机非金属材料,种类繁多,优点是绝缘性好、耐热性强、抗腐蚀性好,机械强度高,但缺点是性脆,耐磨性较差。它是以玻璃球或废旧玻璃为原料经高温熔制、拉丝、络纱、织布等工艺制造成的,其单丝的直径为几个微米到二十几米个微米,相当于一根头发丝的  1/20-1/5  ,每束纤维原丝都由数百根甚至上千根单丝组成。

2. Glass fiber is an inorganic non-metallic material with excellent performance. It has a wide variety. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittle and poor wear resistance. It is made of glass balls or waste glass through high-temperature melting, drawing, winding, weaving and other processes. The diameter of its monofilament is several microns to more than 20 meters, which is equivalent to 1 / 20-1 / 5 of a hair filament. Each bundle of fiber precursor is composed of hundreds or even thousands of monofilaments.
3、环氧树脂板是环氧树脂,纱,脱膜剂,固化剂拉挤成型。固化后的环氧树脂体系是一种具有高介电性能、耐表面漏电、耐电弧的优良绝缘材料,它们和不饱和聚酯树脂、酚醛树脂相比,在固化过程中显示出很低的收缩性(小于2%)。  环氧价格要高于玻纤一倍左右
3. Epoxy resin board is pultruded with epoxy resin, yarn, film remover and curing agent. The cured epoxy resin system is an excellent insulating material with high dielectric properties, surface leakage resistance and arc resistance. Compared with unsaturated polyester resin and phenolic resin, they show very low shrinkage (less than 2%). The price of epoxy is about twice that of glass fiber
