[0049] Performance detection test

[0050] Pipe winding test: cut 0.4 cm wide and 0.8 cm long embroidered heat pipe winding material as a sample for pipe winding test, place the sample in the oven at 175℃ for 3-5s, then take it out, observe and record the pipe winding situation of the embroidered heat pipe winding material after winding into a bead pipe and the interlayer cracking situation of the embroidered heat pipe winding material, and the results are recorded in Table 1.

[0051] Table 1: Detection results of pipe winding and interlayer cracking of embroidered heat pipe winding material

[0052] Test results Did not spill within 2 minutes No intercoat cracking Example 1 Did not spill within 2 minutes No intercoat cracking Example 2 Did not spill within 2 minutes No intercoat cracking Example 3 Did not spill within 2 minutes No intercoat cracking Example 4 Did not spill within 2 minutes Slight intercoat cracking Example 5 Did not spill within 2 minutes Slight intercoat cracking Example 6 Spilled within 2 minutes No intercoat cracking Example 7 Spilled within 2 minutes No intercoat cracking Example 8 Spilled slightly within 2 minutes Slight intercoat cracking Example 9 Spilled slightly within 2 minutes Slight intercoat cracking

[0053] As can be seen from Table 1, the embroidered heat pipe winding material of Examples 1-3 does not uncoil within 2 minutes, and the layers of the embroidered heat pipe winding material do not crack, so it can be seen that the embroidered heat pipe winding material prepared in the present application has good pipe winding performance on the basis of enriching color patterns.

[0054] As shown in Table 1, the difference between Example 4, 5 and Example 3 is only that the mass ratio of polyurethane resin, toluene diisocyanate and ethyl acetate in Example 4 is 0.3:0.023:0.6, the mass ratio of polyurethane resin, toluene diisocyanate and ethyl acetate in Example 4 is 0.3:0.023:0.8, the embroidery heat pipe material in Example 4, 5 is not scattered in 2 minutes, there is slight cracking between the layers of the embroidery heat pipe material, the embroidery heat pipe material in Example 3 is not scattered in 2 minutes, and there is no cracking between the layers of the embroidery heat pipe material, the pipe performance of Example 4, 5 and Example 3 has decreased; this is because the proportion of each component in the adhesive is adjusted, the mass ratio of polyurethane resin, toluene diisocyanate and ethyl acetate is not within the limited range, the adhesion of the adhesive has decreased, and thus the bonding force between the layers of the embroidery heat pipe material has decreased, the embroidery heat pipe material is curled into a bead pipe after heating, the cracking between the layers occurs during the heat curling process, and the pipe performance has decreased.

[0055] As shown in Table 1, the difference between Example 6, 7 and Example 3 is only that the molecular weight of polyethylene terephthalate A in Example 6 is 10000, the molecular weight of polyethylene terephthalate B in Example 6 is 10000, the molecular weight of polyethylene terephthalate A in Example 7 is 10000, the molecular weight of polyethylene terephthalate B in Example 7 is 20000, the embroidery heat pipe material in Example 6, 7 is scattered in 2 minutes, and there is no cracking between the layers of the embroidery heat pipe material, the pipe performance of Example 6, 7 and Example 3 has decreased; this is because the molecular weight of polyethylene terephthalate A and polyethylene terephthalate B in the embroidery heat pipe material is adjusted, when the molecular weight of polyethylene terephthalate A is greater than or equal to the molecular weight of polyethylene terephthalate B, the heat pipe material is not easy to curl, and the scattering phenomenon is easy to occur, and the pipe performance has decreased.

[0056] As shown in Table 1, the difference between Example 8 and Example 3 is only that the number of corona treatment of PET substrate and shrinkage layer in Example 8 is 0 times, the embroidery heat pipe material in Example 8 has slight scattering phenomenon in 2 minutes, and there is slight cracking between the layers of the embroidery heat pipe material, the pipe performance of Example 8 and Example 3 has decreased, this is because no corona treatment is performed, the active groups on the surface of the PET substrate and the shrinkage layer in the embroidery heat pipe material are reduced, the surface tension is decreased, the bonding performance between the layers is decreased, and thus the scattering and cracking phenomenon is easy to occur during the heat curling process, and the pipe performance has decreased.

[0057] As can be seen from Table 1, the difference between Example 9 and Example 3 is that the number of times of the corona treatment of the PET substrate and the shrinkage layer in Example 9 is 6 times, the embroidered heat pipe material in Example 9 is slightly scattered in 2 minutes, the layers of the embroidered heat pipe material are slightly cracked, and the heat pipe performance of the embroidered heat pipe material in Example 9 is slightly decreased compared with that in Example 3; this is because the increase of the number of times of the corona treatment is limited to the improvement of the surface tension of the embroidered heat pipe material, and the stability of the material is reduced, the heat pipe performance is slightly decreased, and therefore 3 times of the corona treatment is selected as the preferred.

[0058] The specific embodiments are only an explanation of the present application, and are not a limitation of the present application.
