[0031] A preparation method of a high-performance multi-network structure elastomer,
[0032] Including the following steps:
[0033] Step S1, first place AEM rubber and magnesium oxide (MgO) in an internal mixer and knead for 20 minutes, then cool to room temperature and discharge;
[0034] In step S2, the rubber after mixing is placed in an open rubber mixing machine to cover rolls, and then N,N'-di-o-tolylguanidine (DOTG), stearic acid, polyoxyethylene stearyl ether phosphate, Diak No. 1st grade additives (the above additives are put in one by one) respectively, and kneaded for 8 minutes. During this period, make a triangle bag three times, and cut 3 / 4 knife three times; finally, put the mixed rubber out of the roll for the last time to make a thickness of about 0.4cm. Left and right flake samples;
[0035] Step S3, sample 65-70g / piece of the mixed rubber, place it in a mold, put it into a flat vulcanizer and vulcanize it at 170°C for 30 minutes to obtain a high-performan...

[0046] A preparation method (blank sample) of high-performance multi-network structure rubber, comprising the steps:
[0047] (1) First weigh 100 parts by weight of ethylene-acrylate rubber, place it in an internal mixer and stir for 33 minutes at a stirring temperature of 120±5°C, then discharge and cool to room temperature;
[0048] (2) Weigh N,N'-di-o-tolylguanidine (DOTG), stearic acid, polyoxyethylene stearyl ether phosphate, hexamethylene diamine carbamate (Diak No.1) 4, 1.5, 1.5, 1.5 parts by weight respectively;
[0049] (3) Put the AEM in the open mill to wrap the rolls, turn on the cooling water to cool down, add the above four additives respectively, cut 3 / 4 knife three times during the mixing process, and pack the triangle three times to make the additives in the rubber Disperse evenly, place the flakes in a dry place, and control the roller temperature of the open mill to be lower than 60°C;
[0050] (4) Vulcanize the AEM compound rubber in a flat vulcanizer, th...
Embodiment 2
[0052] A preparation method (zinc oxide contrast sample) of high-performance multi-network rubber, comprising the steps:
[0053] (1) First take by weighing 100 parts by weight of ethylene-acrylate rubber, place it in an internal mixer and stir for 3 minutes, then place 5 parts by weight of zinc oxide in the internal mixer, and mix the two at a mixing temperature of 120±5°C, the mixing time is 30min, then discharge and cool to room temperature;
[0054] (2) Weigh N,N'-di-o-tolylguanidine (DOTG), stearic acid, polyoxyethylene stearyl ether phosphate, hexamethylene diamine carbamate (Diak No.1) 4, 1.5, 1.5, 1.5 parts by weight respectively;
[0055] (3) Put the AEMZnO compounded rubber in the open mill to cover the rolls, turn on the cooling water to cool down, add the above four additives respectively, cut 3 / 4 knife three times during the mixing process, and make triangular bags three times, so that the additives Disperse evenly in the rubber material, place the sheet in a dr...
