Measuring the transverse length (shown in figure 4 in the definition drawing of the transverse length) of the mold cup, and marking as B1; pulling the mold cup transversely for 30s with 5N force (the two tension clamping pieces are respectively clamped on the side ratio of the mold cup), measuring the longitudinal length of the mold cup, and marking as B2 after placing for 5 min; the deformation ratio of the transverse length = B2-B1/B1 × 100%, and the specific data is shown in table 3;

TABLE 3 Experimental data for examples 2-10 and comparative examples 1-5

It can be seen from table 3 above that when the temperature of the mold pressing or hot pressing reaches 200 ℃, the mold cup is yellowed, and when the temperature is as low as 100 ℃, the connection of the layer structure of the mold cup is unstable, and the degumming phenomenon occurs, and when the TPU adhesive film is replaced by the TPE adhesive film, the degumming phenomenon also occurs.

Comparing comparative example 4 with example 2, it can be seen that the longitudinal and transverse length deformation ratios of comparative example 4 are both greater than those of example 2, which indicates that the comparative example is deformed more significantly, and it can be seen that the mold cup manufactured by the method is not easily deformed.

Comparing comparative example 5 and example 2, it can be seen that the longitudinal and transverse length deformation ratios of comparative example 5 are greater than those of example 2, which shows that the mold cup is deformed when no setting part is added, and the deformation is shown in figure 5 of the accompanying drawings, which shows that the adding of the setting part in the application has better setting effect.

1. Coefficient of thermal conductivity

The modified TPU adhesive films obtained in examples 7-9 and comparative examples 6-7 were tested by a thermal conductivity tester according to the test of national standard GB/T2588-2008, and are shown in Table 4.

4. Adhesion test

The modified TPU glue films obtained in examples 7-9 and comparative examples 6-7 were subjected to the following tests, comprising the following specific steps: sequentially stacking the TPU plate, the modified TPU adhesive film and the TPU plate, performing hot pressing at 150 ℃ for 40s, and cooling for 50min to obtain a composite plate; the thickness of the TPU plate is 2mm, and the width and the length of the TPU plate are both 10cm; cutting a 2mm opening at the bonding position of the composite board, detecting the peeling strength by adopting an 80-degree peeling force tester model XM-DZ01, peeling at 180 ℃, testing at the speed of 150mm/min, separating the composite board, and recording related data when the TPU board is separated, wherein the specific data are shown in a table 4;

TABLE 4 Experimental data for examples 7-9 and comparative examples 6-7

Test item	Coefficient of thermal conductivity (W/m.k)	Peel strength (N/mm)
			Example 7	12.1	7.4
Example 8	11.3	6.9
			Example 9	11.6	7.2
Comparative example 5	11.0	3.5
			Comparative example 6	7.3	6.8

As can be seen from Table 4, when no acrylic rosin is added, the obtained modified TPU adhesive film has poor adhesion, which shows that the adhesion of the modified TPU adhesive film is effectively improved by adding the acrylic rosin. In addition, when hexagonal boron nitride is not added, the heat conduction effect of the modified TPU adhesive film is reduced, so that the nanometer zinc white powder, the hexagonal boron nitride and the silicon micropowder are adopted for compounding, the good heat conduction effect is achieved, the layer structure of the mold cup can be heated uniformly, and the prepared mold cup is stable in structure.
