Embodiment 1

[0029] like Figure 1~3 Shown, a kind of preparation equipment of wide-width continuous fiber-reinforced thermoplastic coil, this equipment comprises the first prepreg roll set, the second prepreg roll set, the first pinch roll 9, the second pinch roll 11, Horizontal laying material box 20, conveyor belt 21, transmission support roller 10, oven 13, first rolling mill 14, second rolling mill 15, cross shear 16, transmission roller 17 and winder 19, the first prepreg roller group consists of 4 The first prepreg roll 1, the second prepreg roll 2, the third prepreg roll 3 and the fourth prepreg roll 4 are arranged staggered in the transverse direction, and the second prepreg roll group consists of 4 transverse The fifth prepreg roll 5, the sixth prepreg roll 6, the seventh prepreg roll 7, and the eighth prepreg roll 8 are arranged staggered in the direction to ensure the vertical seamless splicing of the drawn prepreg tape. One prepreg roll set is located before the first pinch r...

Embodiment 2

[0034] The method for preparing a wide-width continuous fiber-reinforced thermoplastic coil using the equipment described in Example 1 comprises the following steps;

[0035]Lead the narrow prepreg tape from the first prepreg roll 1, the second prepreg roll 2, the third prepreg roll 3 and the fourth prepreg roll 4 at a speed of 1.8m / min to The first pinch roller 9 is seamlessly spliced ​​at the first pinch roller 9 to form the bottom layer of the prepreg tape of required width, and then passes through the conveyor belt 21 to obtain the transverse prepreg tape in the horizontal laying material box 20 above the conveyor belt 21 , horizontally and seamlessly laid on the bottom layer of the prepreg tape to form the middle layer of the prepreg tape, the fifth prepreg roll 5, the sixth prepreg roll 6, and the seventh prepreg roll staggered from the rear end of the conveyor belt 21 7 and the eighth prepreg roll 8 lead out the narrow prepreg tape and splice seamlessly at the second pi...

Embodiment 3

[0038] Utilize the method described in embodiment 1 to prepare wide-width continuous fiber reinforced thermoplastic coil, comprise the following steps:

[0039] Lead the narrow prepreg tape from the first prepreg roll 1, the second prepreg roll 2, the third prepreg roll 3 and the fourth prepreg roll 4 to the first prepreg roll at a speed of 3m / min. A pinch roller 9 is seamlessly spliced ​​at the first pinch roller 9 to form the bottom layer of the prepreg tape of required width, and then passes through the conveyor belt 21 to obtain the transverse prepreg tape in the horizontal laying material box 20 above the conveyor belt 21, Horizontally seamlessly lay 2 layers on the bottom layer of the prepreg tape to form the middle layer of the prepreg tape. The fifth prepreg roll 5, the sixth prepreg roll The prepreg roll 7 and the eighth prepreg roll 8 lead out the narrow prepreg tape and splice seamlessly at the second pinch roll 11 to form a required wide prepreg surface layer and l...

Abstract

The invention relates to a wide-width continuous fiber enhanced thermoplastic coiled material as well as a preparation method and equipment of the wide-width continuous fiber enhanced thermoplastic coiled material. The preparation method comprises the following steps: seamlessly splicing narrow-width prepreg tape raw materials; vertically or transversely paving; and heating, extruding and compounding, cutting and coiling to obtain the wide-width continuous fiber enhanced thermoplastic coiled material. Compared with the prior art, the produced wide-width continuous fiber enhanced thermoplastic coiled material has the advantages of wide width, wide thickness range, strong strength, low elongation and reversion rate, good sustained tension and long service life; the wide-width continuous fiber enhanced thermoplastic coiled material can be applied to various fields including cars, transportation, buildings and the like.

Description

technical field [0001] The invention relates to a coiled material and a manufacturing method thereof, in particular to a wide-width continuous fiber-reinforced thermoplastic coiled material and a manufacturing method and equipment thereof. Background technique [0002] At present, due to the limitations of equipment and processing technology, most of the continuous fiber reinforced thermoplastic coils are relatively narrow in width, but the products produced in many application fields have wider widths, and wider continuous fiber reinforced thermoplastic coils are required. For example, the inner liner of the container requires the coil to have a long size and width, and the coil for building plate reinforcement also requires a large length and width. The new type of van also requires the coil to be continuous and wide of. However, when narrow-width continuous fiber-reinforced thermoplastic coils are prepared for wide-width products, not only the processing technology is co...
