Embodiment 1
[0021] A method for manufacturing a weather-resistant rubber, the specific steps are:
[0022] (1) Add rubber raw materials, including vulcanized rubber particles, silicone resin and auxiliary agents, to the pre-reforming reactor, and
[0023] Polymerize to form rubber-packed vulcanized rubber; the polymerization proceeds until the conversion rate is 80% of the phase inversion starting point of the formed vulcanized rubber particle-organic silicon resin-colloidal vulcanized rubber mixture; : 80%, 10%, 10%; and the components of the auxiliary agent and the mass percentages of each component are: compatibilizer: 65%, plasticizer: 10%, stabilizer: 20%, white oil: 5% %;
[0024] (2) separating the mixture formed in step (1) to generate a first stream comprising 75wt% of the mixture in step (1) and a second stream comprising the remainder of the mixture formed in step (1);
[0025] (3) adding the first stream to the second reactor for further polymerization of vulcanized rubber p...
Embodiment 2
[0031] A method for manufacturing a weather-resistant rubber, the specific steps are:
[0032] (1) Add rubber raw materials, including vulcanized rubber particles, silicone resin and auxiliary agents, to the pre-reforming reactor, and
[0033] Polymerize to form rubber vulcanized rubber; the polymerization proceeds until the conversion rate is 86% of the phase inversion starting point of the formed vulcanized rubber particle-organic silicon resin-colloidal vulcanized rubber mixture; : 88%, 7%, 5%; and the components of the auxiliary agent and the mass percentages of each component are: compatibilizer: 70%, plasticizer: 10%, stabilizer: 10%, white oil: 10% %;
[0034] (2) separating the mixture formed in step (1) to generate a first stream comprising 82 wt% of the mixture in step (1) and a second stream comprising the remainder of the mixture formed in step (1);
[0035] (3) adding the first stream to the second reactor for further polymerization of vulcanized rubber particle...
Embodiment 3
[0041] A method for manufacturing a weather-resistant rubber, the specific steps are:
[0042] (1) Add rubber raw materials, including vulcanized rubber particles, silicone resin and auxiliary agents, to the pre-reforming reactor, and
[0043] Polymerize to form rubber-packed vulcanized rubber; the polymerization proceeds until the conversion rate is 96% of the phase inversion starting point of the formed vulcanized rubber particle-organic silicon resin-colloidal vulcanized rubber mixture; : 80%, 15%, 5%; and the components of the auxiliary agent and the mass percentages of each component are: compatibilizer: 65%, plasticizer: 10%, stabilizer: 15%, white oil: 10% %;
[0044] (2) separating the mixture formed in step (1) to generate a first stream comprising 90wt% of the mixture in step (1) and a second stream comprising the remainder of the mixture formed in step (1);
[0045] (3) adding the first stream to the second reactor for further polymerization of vulcanized rubber p...
