Embodiment 1
[0067] In this example, a composite electric stress control belt is prepared, specifically:
[0068] (1) Raw materials, in parts by mass: 100 parts of PVC with a molecular weight of 80,000 to 120,000, 70 parts of diisononyl phthalate, 2.5 parts of dioctyl adipate, 3 parts of calcium zinc stabilizer, bisphenol A1 27 parts of aluminum powder are mixed to form a composite electrical stress belt lining;
[0069] (2) Weigh the raw materials of the lining layer in step (1) and carry out co-mixing in the internal mixer, and knead in the internal mixer heated to 150°C for 40 minutes, and then add the lining material to the temperature raised to 150°C for kneading Machine kneading and making 3 triangular bags, and store after thinning the slices;
[0070] (3) Raw materials, in parts by mass: 100 parts of butyl rubber, 30 parts of polyisobutylene rubber, 145 parts of barium titanate, 4 parts of erucamide, 29 parts of carbon black, 26 parts of talcum powder, ethylene-ethyl acetate 10 p...
Embodiment 2
[0074] In this example, a composite electric stress control belt is prepared, specifically:
[0075] (1) Raw materials, in parts by mass: 100 parts of PVC with a molecular weight of 80,000 to 120,000, 60 parts of diisononyl phthalate, 2 parts of dioctyl adipate, 2 parts of calcium zinc stabilizer, bisphenol A0 .8 parts and 48 parts of aluminum powder are mixed to form a composite electric stress belt lining;
[0076] (2) Weighing the liner raw material of step (1) and carrying out co-mixing in an internal mixer. Mix in an internal mixer heated to 165°C for 50 minutes, then add the lining material to the open mixer that has been heated to 155°C, knead and make about 5 triangular bags, thinly pass the sheet and store it;
[0077] (3) Raw materials, in parts by mass: 100 parts of butyl rubber, 25 parts of polyisobutylene rubber, 125 parts of barium titanate, 3.5 parts of erucamide, 22 parts of carbon black, 18 parts of talcum powder, ethylene-ethyl acetate 7 parts of copolymer ...
Embodiment 3
[0081] In this example, a composite electric stress control belt is prepared, specifically:
[0082] (1) Raw materials, in parts by mass: 100 parts of PVC with a molecular weight of 80,000 to 120,000, 42 parts of diisononyl phthalate, 1.8 parts of dioctyl adipate, 1.8 parts of calcium zinc stabilizer, bisphenol A0 .7 parts and 48 parts of aluminum powder are mixed to form a composite electric stress belt lining;
[0083] (2) Weigh the raw materials of the lining layer in step (1) and carry out co-mixing in the internal mixer, and knead in the internal mixer heated to 135°C for 55 minutes, and then add the lining material to the temperature raised to 145°C for kneading Machine kneading and making 3 triangular bags, and store after thinning the slices;
[0084] (3) Raw materials, in parts by mass: 100 parts of butyl rubber, 39 parts of polyisobutylene rubber, 168 parts of barium titanate, 6.8 parts of erucamide, 46 parts of carbon black, 37 parts of talcum powder, ethylene-ethy...
