环氧树脂属于热塑性的线型树脂，不能直接应用，必须向其中添加固化剂组分，生成三维网络结构才能体现其独特的性能。在固化剂产品中，酸酐类固化剂占有重要地位，是固化剂市场用量较大，应用较为广泛的品种之一。
Epoxy resin is a kind of thermoplastic linear resin, which can not be directly used. It is necessary to add curing agent components to it to form a three-dimensional network structure to reflect its unique performance.

环氧树脂和酸酐类固化剂及其他添加剂（如促进剂、增韧剂、填料、偶联剂、颜料等经过加热，通过各种加工工艺，形成不同形态的热固性加成物。酸酐体系固化剂的特点是收缩率小、没有副产物，耐热性好，密封性佳，绝缘性好，各种助剂选择性大。可应用在电子灌封、电器浇注、包封、拉挤、缠绕、层压绝缘材料及复合材料、粉末涂料等领域。
Epoxy resin, anhydride curing agent and other additives (such as accelerant, toughening agent, filler, coupling agent, pigment, etc.) are heated to form different forms of thermosetting adducts through various processing technologies. The curing agent of anhydrides system is characterized by small shrinkage, no by-products, good heat resistance, good sealing, good insulation and high selectivity of various additives. It can be used in electronic potting, electrical pouring, encapsulation, pultrusion, winding, laminated insulating materials and composite materials, powder coating and other fields.

拉挤成型时将浸渍树脂胶液的连续玻璃纤维束、带或布等，在牵引力的作用下，连续不断地生产长度不限的玻璃钢型材。这种工艺适合生产各种断面形状的玻璃钢型材，如棒，管，工字形、槽形、方形型材和空腹型材等。
During pultrusion, continuous fiberglass bundles, belts or cloth impregnated with resin glue are continuously produced with unlimited length fiberglass profiles under the action of traction. This process is suitable for producing FRP profiles with various cross-section shapes, such as bar, tube, I-shape, groove, square profile and hollow profile.
拉挤制品生产中，环氧树脂体系固化剂一般采用酸酐类固化剂。尽管也采用不饱和树脂拉挤成型加工，但其综合性能，尤其在机械性能、绝缘性能、收缩率方面，均不如环氧树脂拉挤产品。
In the production of pultrusion products, the curing agent of epoxy resin system is generally anhydrides. Although it is also processed by pultrusion of unsaturated resin, its comprehensive properties, especially in mechanical properties, insulation properties and shrinkage, are not as good as epoxy pultrusion products.
3、 层压产品
3. Laminated products

The epoxy laminated product is a kind of glue liquid which is made up of fiber fabric reinforced material impregnated with epoxy resin / curing agent. After drying at a certain temperature, the semi-cured sheet is obtained. The semi-cured sheet is cut and laminated, then hot pressed and solidified into plate, and then heated and solidified into tube and tube.
层压产品使用环氧树脂体系中，主要使用酸酐类固化剂，胺类固化剂使用双氰胺及芳香胺，也有采用合成树脂作固化剂。

4、 缠绕制品
4. Winding products
缠绕制品是将浸过树脂的连续纤维（布、予浸纱）按照一定规律缠绕到芯模上，然后经过固化、脱模而获得一定形状制品。
Winding products are made by winding resin impregnated continuous fibers (cloth, pre impregnated yarn) onto the core mould according to certain rules, and then solidify and demould to obtain certain shape products.
缠绕制品更具代表性的是使用期长、粘度小、发热量少、毒性小的环氧固化体系，故一般都选用液体酸酐为主。
The most representative of winding products is the epoxy curing system with long service life, small viscosity, less heat and less toxicity, so liquid anhydrides are generally selected as the main component.
