Embodiment 1
[0021] First, put 100 parts of chloroprene rubber, 25 parts of N-550 carbon black, 20 parts of decabromodiphenylethane, 15 parts of antimony trioxide, and 18 parts of dioctyl sebacate raw materials into the internal mixer according to parts by weight The temperature is 95 ℃, the pressure is 110Kgf / cm2 under the conditions of banburying for 6 minutes to obtain banburying rubber.
[0022] Next, the above-mentioned banbury rubber was tested, and the banbury rubber with a hardness of 51 degrees, a strength of 13.1MPa, an elongation of 450%, and a burning time of 1.5S was screened out. Put the screened banbury rubber into an open mill and carry out kneading for 4 minutes at a temperature of 55°C to extrude. The pressure is 170Kgf / cm2, the temperature is raised to 175°C, and the vulcanization treatment is carried out for 360 seconds. After trimming the vulcanized rubber.
[0023] Finally, inspection, packaging and storage are carried out to obtain the fixing sleeve.
Embodiment 2
[0025] First, put 100 parts of chloroprene rubber, 30 parts of N-550 carbon black, 15 parts of decabromodiphenylethane, 20 parts of antimony trioxide, and 20 parts of dioctyl sebacate raw materials into the internal mixer according to parts by weight The temperature is 95 ℃, the pressure is 110Kgf / cm2 under the conditions of banburying for 6 minutes to obtain banburying rubber.
[0026] Next, the above-mentioned banbury rubber was tested, and the banbury rubber with a hardness of 52 degrees, a strength of 13.7MPa, an elongation of 441%, and a burning time of 2S was screened out. Put the screened banbury rubber into an open mill and carry out kneading for 4 minutes at a temperature of 55°C to extrude. The pressure is 170Kgf / cm2, the temperature is raised to 175°C, and the vulcanization treatment is carried out for 360 seconds. After trimming the vulcanized rubber.
[0027] Finally, inspection, packaging and storage are carried out to obtain the fixing sleeve.
Embodiment 3
[0029] First, put 100 parts of chloroprene rubber, 20 parts of N-550 carbon black, 20 parts of decabromodiphenylethane, 20 parts of antimony trioxide, and 15 parts of dioctyl sebacate raw materials into the internal mixer according to parts by weight The temperature is 95 ℃, the pressure is 110Kgf / cm2 under the conditions of banburying for 6 minutes to obtain banburying rubber.
[0030] Next, the above-mentioned banbury rubber was tested, and the banbury rubber with a hardness of 52 degrees, a strength of 12.6MPa, an elongation of 433%, and a burning time of 0S was screened out. Put the screened banbury rubber into an open mill and carry out kneading for 4 minutes at a temperature of 55°C to extrude. The pressure is 170Kgf / cm2, the temperature is raised to 175°C, and the vulcanization treatment is carried out for 360 seconds. After trimming the vulcanized rubber.
[0031] Finally, inspection, packaging and storage are carried out to obtain the fixing sleeve.
