[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] See also Figure 1 The utility model provides a technical solution: an antistatic PET sheet, comprising a sheet body 1, the sheet body 1 comprising: a PET substrate 2; a functional layer 3, the functional layer 3 being compounded on the top surface of the PET substrate 2, the functional layer 3 being used to increase the antistatic and tearing strength of the sheet body 1; a first wear-resistant layer 4, the first wear-resistant layer 4 being compounded on the top surface of the functional layer 3, the first wear-resistant layer 4 being used to enhance the wear resistance of the top surface of the sheet body 1; a second wear-resistant layer 5, the second wear-resistant layer 5 being compounded on the bottom surface of the PET substrate 2, the second wear-resistant layer 5 being used to enhance the wear resistance of the bottom surface of the sheet body 1; and a second antistatic agent 6, the second antistatic agent 6 being sprayed on the upper surface of the first wear-resistant layer 4 and the bottom surface of the second wear-resistant layer 5, the second antistatic agent 6 being used to enhance the antistatic strength of the sheet body 1;
[0028] The PET substrate 2 in the sheet body 1 can provide an attachment basis for the functional layer 3 and the second wear-resistant layer 5. Since the first wear-resistant layer 4 is compounded on the top surface of the functional layer 3, and the second antistatic agent 6 is sprayed on the upper surface of the first wear-resistant layer 4 and the bottom surface of the second wear-resistant layer 5, the second antistatic agent 6 on the outer wall of the first wear-resistant layer 4 and the second wear-resistant layer 5 can prevent static electricity from accumulating on the outer wall of the sheet body 1, thereby improving the antistatic effect of the sheet body 1, and the functional layer 3 can not only further prevent static electricity from penetrating, but also strengthen the structural strength of the sheet body 1, and at the same time reduce the penetration of light, so as to improve the functionality of the sheet body 1.
[0029] See Figure 1 、 Figure 3 and Figure 4The functional layer 3 includes a heat-insulating layer 31, the top surface of the heat-insulating layer 31 is compounded with a matte layer 32, and the top surface of the matte layer 32 is adhesively connected to the bottom surface of the first wear-resistant layer 4; the bottom surface of the heat-insulating layer 31 is compounded with a tear-resistant layer 33, and the bottom surface of the tear-resistant layer 33 is adhesively connected to the top surface of the PET substrate 2, the bottom surface of the tear-resistant layer 33 is sprayed with a first antistatic agent 34, and the tear-resistant layer 33 is woven with a first tensile-resistant fiber filament 331 and a second tensile-resistant fiber filament 332, and the first tensile-resistant fiber filament 331 and the second tensile-resistant fiber filament 332 are both made of aramid fiber;
[0030] The heat-insulating layer 31 in the functional layer 3 can not only play a heat-insulating effect, but also provide an attachment basis for the matte layer 32 and the tear-resistant layer 33. Then, the matte layer 32 can effectively reduce the penetration of external light, so that the visual effect of the sheet body 1 can be made softer, and the sheet body 1 can be suitable for occasions where light interference needs to be reduced. The tear-resistant layer 33 woven by the first anti-tensile fiber filament 331 and the second anti-tensile fiber filament 332 can enhance the structural strength of the sheet body 1, thereby increasing the service life of the sheet body 1. At the same time, the first antistatic agent 34 can prevent static electricity from penetrating the functional layer 3, further improving the antistatic effect of the sheet body 1.
[0031] See Figure 1 、 Figure 3 , the PET substrate 2 and the functional layer 3 and the second wear-resistant layer 5, as well as the functional layer 3 and the first wear-resistant layer 4, and the anti-tear layer 33 and the anti-tear layer 33 are fixed together by an adhesive, and the adhesive is UV glue;
[0032] UV glue can effectively fix the PET substrate 2 and the functional layer 3 and the second wear-resistant layer 5, the functional layer 3 and the first wear-resistant layer 4, and the anti-tear layer 33 and the anti-tear layer 33 together, thereby ensuring the stability of the bonding.
[0033] See Figure 1 、 Figure 2 , glue storage grooves 7 are provided on the top and bottom surfaces of the PET substrate 2, and multiple glue storage grooves 7 are distributed in a rectangular array, which can conveniently store a certain amount of adhesive, thereby strengthening the structural strength between the PET substrate 2 and the functional layer 3 and the second wear-resistant layer 5.
[0034] During operation, the PET substrate 2 in the sheet body 1 can provide an attachment basis for the functional layer 3 and the second wear-resistant layer 5. Since the first wear-resistant layer 4 is compounded on the top surface of the functional layer 3, and the second antistatic agent 6 is sprayed on the upper surface of the first wear-resistant layer 4 and the bottom surface of the second wear-resistant layer 5, the second antistatic agent 6 on the outer wall of the first wear-resistant layer 4 and the second wear-resistant layer 5 can prevent static electricity from accumulating on the outer wall of the sheet body 1, thereby improving the antistatic effect of the sheet body 1, and the functional layer 3 can not only further prevent static electricity from penetrating, but also strengthen the structural strength of the sheet body 1, and at the same time reduce the penetration of light, so as to improve the functionality of the sheet body 1.
[0035] The heat-insulating layer 31 in the functional layer 3 can not only play a heat-insulating effect, but also provide an attachment basis for the matte layer 32 and the tear-resistant layer 33. Then, the matte layer 32 can effectively reduce the penetration of external light, thereby making the visual effect of the sheet body 1 softer, and thus making the sheet body 1 suitable for occasions where light interference needs to be reduced. The tear-resistant layer 33 woven by the first tensile fiber filament 331 and the second tensile fiber filament 332 can strengthen the structural strength of the sheet body 1, thereby increasing the service life of the sheet body 1. At the same time, the first antistatic agent 34 can prevent static electricity. Penetrating the functional layer 3 further improves the antistatic effect of the sheet body 1. Through UV glue, the PET substrate 2 and the functional layer 3 and the second wear-resistant layer 5, as well as the functional layer 3 and the first wear-resistant layer 4, and the tear-resistant layer 33 and the tear-resistant layer 33 can be effectively fixed together, thereby ensuring the stability of the bonding. Since the top and bottom surfaces of the PET substrate 2 are provided with glue storage grooves 7, and the multiple glue storage grooves 7 are distributed in a rectangular array, a certain amount of adhesive can be conveniently stored, thereby strengthening the structural strength between the PET substrate 2 and the functional layer 3 and the second wear-resistant layer 5.
[0036] In summary, the device can not only improve the antistatic effect of the sheet body 1, thereby reducing the impact of static electricity on the sheet body 1, but also strengthen the structural strength of the sheet body 1, thereby increasing the service life of the sheet body 1.
