Embodiment 1
[0041] A method for preparing a green recycled carbon fiber thermoplastic material sheet, the green recycled carbon fiber thermoplastic composite material building template is a recycled carbon fiber thermoplastic material, and the recycled carbon fiber thermoplastic material includes a recycled carbon fiber non-woven felt layer 101 and a thermoplastic resin layer 102; The recycled carbon fiber thermoplastic material includes a recycled carbon fiber thermoplastic material. The carbon fiber nonwoven felt layer 101 and the thermoplastic resin layer 102 are formed by thermocompression.
[0042] In order to further explain this embodiment, it should be noted that the regenerated carbon fibers in the regenerated carbon fiber non-woven mat layer 101 are obtained by recycling carbon fiber composite wastes by pyrolysis; the regenerated carbon fibers in the regenerated carbon fiber non-woven mat layer 101 have a length of 50- 100mm, recycled carbon fiber non-woven felt layer is 50-500g / ...
Embodiment 2
[0045] like figure 2 As shown, a preparation method 1 of a green regenerated carbon fiber thermoplastic material sheet, the specific steps are:
[0046] 1) Preparation of recycled carbon fiber;
[0047] 2) Surface modification treatment of recycled carbon fiber, so that recycled carbon fiber and thermoplastic resin have strong bonding force;
[0048] 3) Preparation of regenerated carbon fiber non-woven felt layer 101: The processed recycled carbon fiber is prepared into a regenerated carbon fiber non-woven felt layer through the non-woven felt production equipment and process;
[0049] 4) Preparation of recycled carbon fiber thermoplastic material sheet: The thermoplastic resin powder and processing aid are spread on the upper and lower surfaces of the recycled carbon fiber non-woven felt layer, and the thermoplastic resin layer 102 on the upper and lower surfaces is formed by hot pressing.
[0050] In order to further explain this embodiment, it should be noted that, a pre...
Embodiment 3
[0052] like figure 1 As shown, a preparation method 2 of a green recycled carbon fiber thermoplastic material sheet, the specific steps are:
[0053] 1) Preparation of recycled carbon fiber;
[0054] 2) Surface modification treatment of recycled carbon fiber, so that recycled carbon fiber and thermoplastic resin have strong bonding force;
[0055] 3) Preparation of regenerated carbon fiber non-woven felt layer 101 and thermoplastic resin layer 102: The processed recycled carbon fiber is prepared into a regenerated carbon fiber non-woven felt layer 101 through the non-woven felt production equipment and process, and the thermoplastic resin fiber is prepared into a thermoplastic resin layer 102;
[0056] 4) The recycled carbon fiber thermoplastic material sheet is prepared by heating, pressurizing and cooling.
[0057] In order to further explain this embodiment, it should be noted that 30-60wt% regenerated carbon fiber fiber and 40-70wt% thermoplastic resin fiber are weighed...
