Embodiment Construction
[0006] Production steps of epoxy glass cloth laminate:
[0007] 1. Preparation of epoxy resin glue: hot melt epoxy resin to form glue.
[0008] 2. Dip the electrical alkali-free glass cloth in the glue.
[0009] 3. Arrange the impregnated electrical alkali-free glass in a mold and heat-press and shape it at 160-170°C.
[0010] 4. Remove the film after cooling, and take out the shaped epoxy glass cloth laminate.

The invention provides a production method of an epoxy glass cloth laminated board and relates to the technical field of production and processing techniques of glass cloth laminated boards. The production method comprises the following step of hot pressing and shaping electrician alkali-free glass cloth dipped in epoxy resin solution at a temperature of 160-170 DEG C. The insulating and heat-resistant grade of the epoxy glass cloth laminated board prepared by adopting the production method can achieve Grade B, namely the epoxy glass cloth laminated board also has higher moisture and heat resistance at a high temperature of 130 DEG C. As the epoxy glass cloth laminated board has higher mechanical and electrical property and particularly has higher hot-state mechanical strength retention rate, a pressing plate prepared by adopting the epoxy glass cloth laminated board is more suitable for a Grade-B motor required in flame-retardant grade and other electrical equipment used as an insulating part.
Description
Technical field [0001] The invention relates to the technical field of the production and processing technology of a glass cloth laminate. Background technique [0002] Insulating plates are required in motors and many electrical products, and their insulation effect is relatively high, especially when these electrical appliances are used in a humid environment. The existing insulating plates cannot satisfy the use of electrical appliances under the harsh conditions of high humidity, which directly affects the service life and use effect of the product. Summary of the invention [0003] The purpose of the present invention is to provide a method for producing an epoxy glass cloth laminate with high insulation performance. [0004] The method of the invention is: immersing the electrician's alkali-free glass cloth with epoxy resin glue liquid and then hot pressing and setting the shape at 160-170°C. [0005] The insulating and heat-resistant grade of the epoxy glass cloth laminate ma...
