High-temperature-resistant adhesive tape

[0021] Example 1:

[0022] Step 1) Mix 80 kg of polyester film; 1 kg of isooctyl dimercaptoacetate di-n-octyl tin; 1 kg of methacrylic acid-butadiene-styrene copolymer; 2 kg of zirconia; 1 kg of plasticizer; 5 kg of mica powder;

[0023] Step 2) Take two layers of plastic film and place them between the two calender rolls of the calender. Use an extruder to base the mixture obtained in step (1) between the two layers of plastic film. The mixture and the plastic film are continuously extruded into a sheet-like strip;

[0024] Step 3) Pass the obtained sheet-like strip continuously through an electron accelerator to obtain a substrate layer.

[0025] The high temperature resistance test results of the prepared material are shown in Table 1.

[0026] Example 2:

[0027] Step 1) Mix 85 kg of polyester film; 1.5 kg of isooctyl di-n-octyl tin dimercaptoacetate; 3 kg of methacrylic acid-butadiene-styrene copolymer; 3 kg of zirconia; 3 kg of plasticizer; 6.5 kg of mica powder. uniform;

[0028] Step 2) Take two layers of plastic film and place them between the two calender rolls of the calender. Use an extruder to base the mixture obtained in step (1) between the two layers of plastic film. The mixture and the plastic film are continuously extruded into a sheet-like strip;

[0029] Step 3) Pass the obtained sheet-like strip continuously through an electron accelerator to obtain a substrate layer.

[0030] The results of the high temperature resistance of the prepared materials are shown in Table 1.

[0031] Example 3:

[0032] Step 1) Mix 90 kg of polyester film; 2 kg of isooctyl dimercaptoacetate di-n-octyl tin; 5 kg of methacrylic acid-butadiene-styrene copolymer; 4 kg of zirconia; 5 kg of plasticizer; 8 kg of mica powder;

[0033] Step 2) Take two layers of plastic film and place them between the two calender rolls of the calender. Use an extruder to base the mixture obtained in step (1) between the two layers of plastic film. The mixture and the plastic film are continuously extruded into a sheet-like strip;

[0034] Step 3) Pass the obtained sheet-like strip continuously through an electron accelerator to obtain a substrate layer.

[0035] The results of the high temperature resistance of the prepared materials are shown in Table 1.
