一、环氧树脂绝缘板产品介绍
   环氧树脂绝缘板产品是用浸渍纸、棉布、玻璃布、浸渍酚醛、环氧树脂，经烘焙热压而成的硬质板状绝缘材料。环氧酚醛树脂绝缘板具有较高的机械强度、介电性能、耐油性和耐腐蚀性，环氧酚醛树脂绝缘板适用于要求较高的电工机械、电器设备中作绝缘结构件，并可在潮湿环境和变压器中使用，耐热等级为B级。

二、环氧树脂绝缘板产品技术要求
1、环氧树脂绝缘板外观、表面应平整光滑，不允许有杂质和其他明显的缺陷，允许有轻微的擦伤，边缘应切割整齐，端面不得有分层和裂纹。
2、环氧树脂绝缘板尺寸：面积不得小于380×480平方毫米，如需特殊规格，可同供需双方协议生产。其它数据详见机电部标准。
3、环氧树脂绝缘板产品可根用户要求，加工成各种规格板、管、垫、法兰、瓦、等异形件。

三、黄色环氧板技术参数

1、外观 表面应平滑，无气泡、皱纹和裂纹。
2、标称厚度及允许偏差见表1。

注：1如果测得的试样厚度算术平均值是介于表中两厚度之间，则其指标值应从内插法求得。2如果测得的厚度算术平均值小于0.4mm，则其指标值取≤17mg。如果标称厚度为25mm并测得的厚度算术平均值大于25mm时，则其指标值取≤61mg。标称厚度大于25mm的板材，则应从单面加工至22.5mm且加工面应是比较光滑的。
  3240环氧板是由电工用无碱玻璃纤维布浸以环氧酚醛树脂，经烘焙、热压而成。
  3240环氧板具有较高的机械和介电性能，较好的耐热性和耐潮性，并有良好的机械加工性，耐热等级为B级。
  3240环氧板适用于电机、电器设备中作为绝缘结构零部件，并可在潮温环境和变压器油中使用。
  324环氧板以较高的机械性能和电气性能，广泛应用在发电机、马达、电子器具上作为绝缘材料和构件。在变压器油压环境和湿度环境中也非常适用。

7、环氧树脂和所用的固化剂的反应是通过直接加成反应或树脂分子中环氧基的开环聚合反应来进行的，没有水或其它挥发性副产物放出。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%）。
