Embodiment 1
[0050] A tarpaulin for a muck truck, comprising a tarpaulin body 1 and a support arranged on the tarpaulin body 1, the tarpaulin body 1 comprising a continuous fiber-reinforced thermoplastic resin composite material layer 11, an upper surface protection layer 12, and a lower surface protection layer 13 , The upper and lower surfaces of the tarpaulin body 1 are provided with wear-resistant layers. The continuous fiber reinforced thermoplastic resin composite material layer 11 includes two layers of prepreg tapes formed by continuous fibers and thermoplastic resin, and the continuous fibers in the two layers of prepreg tapes are perpendicular to each other. The upper surface protective layer 12 is a PET nonwoven fabric layer covering the upper surface of the continuous fiber reinforced thermoplastic resin composite material layer 11, and the lower surface protective layer 13 is a PET nonwoven fabric layer coated on the lower surface of the continuous fiber reinforced thermoplasti...
Embodiment 2
[0065] The structure of the muck truck tarpaulin of this embodiment is basically the same as that of Embodiment 1, except that the continuous fiber-reinforced thermoplastic resin composite material layer in this embodiment is composed of the following components in weight percent:
[0066]
[0067] The continuous fiber is non-alkali glass roving,
[0068] The compatibilizer is γ-aminopropyltriethoxysilane,
[0069] The antioxidant is tris[2,4-di-tert-butylphenyl]phosphite and tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]pentaerythritol ester in mass ratio A 1:2 mixture is obtained.
[0070] The preparation method of this muck truck tarpaulin is as follows:
[0071] (1) Mix the thermoplastic resin, compatibilizer, color masterbatch, and antioxidant according to the above ratio, and stir for 80 seconds through a low-speed mixer to mix evenly;
[0072] (2) Place multiple bundles of continuous fibers on the creel, which is mainly used to place continuous fiber ro...
Embodiment 3
[0078] The structure of the muck truck tarpaulin of this embodiment is basically the same as that of Embodiment 1, except that the continuous fiber-reinforced thermoplastic resin composite material layer in this embodiment is composed of the following components in weight percent:
[0079]
[0080] The continuous fiber is non-alkali glass roving,
[0081] The compatibilizer is γ-aminopropyltriethoxysilane,
[0082]The antioxidant is tris[2,4-di-tert-butylphenyl]phosphite and tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]pentaerythritol ester in mass ratio A 1:1 mixture was obtained.
[0083] The preparation method of this muck truck tarpaulin is as follows:
[0084] (1) Mix the thermoplastic resin, compatibilizer, color masterbatch, and antioxidant according to the above ratio, and stir for 160s through a low-speed mixer to mix evenly;
[0085] (2) Place multiple bundles of continuous fibers on the creel, which is mainly used to place continuous fiber rolls. ...
