Document Type and Number:
WIPO Patent Application WO/2023/160197
Kind Code:
A1
Abstract:
The present invention discloses a single-component organic silicon-modified sealant and a preparation method therefor. The single-component organic silicon-modified sealant is prepared from the following raw materials: 15 to 40 parts of a trimethoxy silane-terminated polyurea resin, 20 to 50 parts of a reinforcing filler, 3 to 10 parts of a functional filler and 10 to 50 parts of a plasticizer, 0.2 to 1.5 parts of a humectant, 0.1 to 2 parts of a rheological agent, 0.5 to 2 parts of a stabilizer, 0.5 to 2 parts of a water removal agent, 0.5 to 2 parts of a coupling agent, and 0.1 to 3 parts of a catalyst. The functional filler is surface-modified calcium oxide. The deep-layer curing depth of the single-component organic silicon-modified sealant at a low temperature (about 0°C) within 24 hours is greater than or equal to 3 mm, and has good mechanical property after curing.
