Embodiment 1
[0042] A continuous glass fiber reinforced halogen-free flame-retardant resin prepreg tape, prepared according to the following method:
[0043] The glass fiber used in this example is untwisted E-glass fiber; the thermoplastic is polypropylene; the silane coupling agent is vinyltrimethoxysilane; the thermoplastic phenolic resin is phenolic resin 217; high nitrogen flame retardant (MCA) It is melamine cyanurate; the antioxidant is antioxidant 264 (BHT).
[0044] (1) Weigh the raw materials according to the following components by weight:
[0045]
[0046] Add the above raw materials into a high-speed mixer and mix evenly to obtain a mixture;
[0047] (2) The continuous fiber is introduced into the fiber spreading system through the spinning creel for dispersion, the tension is adjusted by the traction system and the tension adjustment system, and then preheated by the infrared heating system to obtain a flat continuous fiber belt;
[0048] (3) Add 45 parts by weight of th...
