Embodiment 1～4

[0039] A method for producing continuous fiber reinforced thermoplastic resin prepreg tapes that can be coated online is as follows: after the continuous fibers are drawn out from the creel 1, they are introduced into the double extrusion die 3 through the tension adjusting device 2; After the die head 3, the molten resin impregnates the continuous fibers, and then is introduced into the three-roller impregnation device 4; the fully infiltrated prepreg tape product passes through the lamination rolling device 5, and the lamination process is completed at the same time; The final prepreg tape is introduced into the cooling rolling device 7; finally, the prepreg tape with complete impregnation and surface coating can be obtained by winding and forming through the pulling and winding device 8.

Abstract

The invention relates to equipment capable of laminating on line for producing continuous fiber-reinforced thermoplastic resin prepreg tapes and a method for producing prepreg tapes by applying the equipment. The equipment comprises a creel (1), a tension regulating device (2), a dual-extrusion die head (3), a three-roller dipping device (4), a cooling and rolling device (7), a traction and reeling device (8), a laminating and rolling device (5), a first film reel (61) and a second film reel (62), wherein the first film reel (61) and the second film reel (62) are arranged on the upper side and the lower side of the laminating laminating and rolling device (5), respectively, and provide films for being laminated on the upper surface and the lower surface of each prepreg tape, and the upper surface and the lower surface of each prepreg tape are laminated by the laminating laminating and rolling device (5) so as to obtain laminated prepreg tapes. Compared with the prior art, the equipment has the advantage that the phenomena of tearing, fiber exposure and the like are prevented due to the adoption of a direct laminating technology; the problem of poor resin infiltration caused by inorganic filler and pigment is prevented; accurate color blending is realized.

Description

technical field [0001] The invention relates to a production equipment and application of a prepreg tape, in particular to a device for producing continuous fiber reinforced thermoplastic resin prepreg tape which can be coated on-line and a method for preparing the prepreg tape by using the device. Background technique [0002] Continuous fiber reinforced thermoplastic resin prepreg tape has excellent mechanical properties, and its low density and recyclability are in line with the concept of energy saving and environmental protection, and have been rapidly developed in recent years. This material can process high-strength plates by molding, and realize the manufacture of structural parts through different molds. [0003] In the later use of the prepreg tape material, if the natural resin is reinforced with continuous fibers, the glass fiber will see through and affect the appearance, and the unidirectional continuous fiber reinforced material has anisotropy and is prone to ...
