preparation example Construction
[0026] The invention provides a method for preparing a fiber-reinforced thermoplastic resin, comprising the following steps:
[0027] Melting the resin mixture to obtain a melt, the resin mixture includes a cyclic polymer monomer or a cyclic polymer oligomer and a catalyst;
[0028] The preheated fiber is infiltrated in the melt, and the fiber-reinforced thermoplastic resin is obtained after molding.
[0029] The present invention directly uses the cyclic polymer monomer or cyclic polymer oligomer that can undergo ring-opening polymerization as a raw material, and wraps the fiber-reinforced material while ring-opening polymerization generates a thermoplastic resin to form a fiber-reinforced thermoplastic resin. The method is simple to operate, has mild conditions, and can obtain a fiber-reinforced thermoplastic resin with good performance.
[0030] In the present invention, the resin mixture is first melted to obtain a melt. In the present invention, the resin mixture includ...
Embodiment 1
[0054] according to figure 1 As shown in the process flow chart, the solar cell frame is prepared according to the following steps:
[0055] Multiple volumes of non-alkali glass roving are unwound by unwinding roller 1 and exported and heated through yarn guide 2, and the number of the single volume of non-alkali glass roving is 2400Tex;
[0056] The CBT160 resin mixture is melted, mixed and plasticized through the twin-screw extruder 3 to obtain a melt. The CBT160 resin mixture includes the following components, each component is based on its mass fraction in the fiber-reinforced thermoplastic resin: 28.4 % CBT resin; 1.0% C10 catalyst from BRUGGOLEN, Germany; 0.2% 2,6-tertiary butyl-4-methylphenol; 0.1% didodecyl alcohol ester; 0.3% hindered amine anti-ultraviolet Aging agent;
[0057] The molten material is introduced into the flat mold 4, and the alkali-free glass roving is fully infiltrated with the heated and melted molten material after being fully opened by the tensi...
Embodiment 2
[0060] according to figure 1 As shown in the process flow chart, the solar cell frame is prepared according to the following steps:
[0061] Multiple volumes of non-alkali glass roving are unwound by unwinding roller 1 and exported and heated through yarn guide 2, and the number of the single volume of non-alkali glass roving is 2400Tex;
[0062] The caprolactam that accounts for 49% of the mass fraction of the caprolactam resin mixture and the catalyst C10 that accounts for 1% of the mass fraction of the caprolactam resin mixture are mechanically mixed at 120 ° C, and after vacuum dehydration for 20 minutes, component A is obtained; the mass fraction of the caprolactam resin mixture is 49 % of caprolactam and the catalyst accelerator C20P that accounts for 1% of the mass fraction of the caprolactam resin mixture are mechanically mixed at 120° C., and component B is obtained after vacuum dehydration for 20 minutes; The mass ratio is fully stirred and mixed to obtain the capro...
