Single-component epoxy structure adhesive for waterproof sealing and preparation method thereof

[0032] Weigh epoxy resin 1, epoxy resin 2 and polyfunctional epoxy resin 2 according to the mass given in table 1, mix with mechanical mixer, stirring rate is 1000 rev / min, time 30 minutes;

[0033] Then add the hydrophobic organic filler and continue to stir for 30 minutes;

[0034] After the mixture is cooled to room temperature, add curing agent 1 and curing agent 2, mechanically stir for 5 minutes, then transfer the mixture to a high-speed shear mixer for mixing, the mixing speed is 2000 rpm, the time is 30 seconds, repeat at high speed The mixing process in the shear mixer was performed three times to obtain a uniformly mixed jelly, which was the one-component epoxy structural adhesive for waterproof sealing.

[0036] Weigh epoxy resin 1, epoxy resin 2, polyfunctional epoxy resin 1, and polyfunctional epoxy resin 2 according to the mass given in Table 1, and mix them with a mechanical mixer at a stirring rate of 1000 rpm for 30 minutes ;

[0037] Then add the hydrophobic inorganic filler and continue to stir for 30 minutes;

[0038] After the mixture is cooled to room temperature, add curing agent 1 and curing agent 2, mechanically stir for 5 minutes, then transfer the mixture to a high-speed shear mixer for mixing, the mixing speed is 2000 rpm, the time is 30 seconds, repeat at high speed The mixing process in the shear mixer was performed three times to obtain a uniformly mixed jelly, which was the one-component epoxy structural adhesive for waterproof sealing.

[0040] Weigh epoxy resin 1 and polyfunctional epoxy resin 2 according to the mass given in table 1, mix with mechanical mixer, stirring rate is 1000 rev / min, time 30 minutes;

[0041] Then add hydrophobic inorganic filler and hydrophobic organic filler, continue to stir for 30 minutes;

[0042] After the mixture is cooled to room temperature, add curing agent 1 and curing agent 2, mechanically stir for 5 minutes, then transfer the mixture to a high-speed shear mixer for mixing, the mixing speed is 2000 rpm, the time is 30 seconds, repeat at high speed The mixing process in the shear mixer was performed three times to obtain a uniformly mixed jelly, which was the one-component epoxy structural adhesive for waterproof sealing.
