其实环氧树脂在20世纪40年代末的一次商业化生产后，成为一个广泛的材料家族。环氧树脂由于其高强度、多功能性和优异的表面附着力，在涂料、电气、铸造树脂、复合材料等领域得到了广泛的应用。

　　In fact, epoxy resin has become a wide family of materials after the primary commercial production in the late 1940s. Epoxy resin has been widely used in coatings, electrical, casting resin, composite materials and other fields because of its high strength, versatility and excellent surface adhesion.

　　热固性树脂，即热固性树脂，是一种利用热或辐射等固化方法固化或固化成硬形状的聚合物。固化过程是不可逆的，因为它引入了由共价化学键交联的聚合物网络。

　　Thermosetting resin, that is, thermosetting resin, is a kind of polymer which is cured or cured into hard shape by curing method such as heat or radiation. The curing process is irreversible because it introduces polymer networks crosslinked by covalent chemical bonds.

　　与热塑性塑料不同的是，在加热时，热固性会保持固态，直到温度达到热固性开始降解的程度。

　　Unlike thermoplastics, thermosets remain solid when heated until the temperature reaches the point where thermosetting begins to degrade.

　　酚醛树脂、氨基树脂、聚酯树脂、硅树脂、环氧树脂和聚氨酯(聚酯、乙烯基酯、环氧树脂、双马来酰亚胺、氰酸酯、聚酰亚胺和酚醛树脂)是热固性树脂的少数例子。

　　Phenolic resin, amino resin, polyester resin, silicone resin, epoxy resin and polyurethane (polyester, vinyl ester, epoxy resin, bisMaleimide, cyanoate, polyimide and phenolic resin) are a few examples of thermosetting resins.

　　其中，环氧树脂或环氧树脂是当今结构和特殊复合材料应用中常见和广泛使用的热固性材料之一。由于它们的高强度和刚性(因为高度的交联)。环氧树脂热固性树脂几乎适用于任何用途。
