Examples
Embodiment 1
[0094] Mix dimethylpolysiloxane, methyltriacetoxysilane, dibutyltin dilaurate and potassium superoxide with a viscosity of 100 mPas at room temperature and hydroxyl-terminated ends of the molecular chain at the contents shown in Table 1 below. To prepare polymer compositions for air purification (sample Nos. 1-4). After the polymer composition is fully cured, it is stored in a desiccator filled with nitrogen.
[0095] Table 1 Composition and content (embodiment 1) of each air purification sample
[0096]
[0097] The above polymer composition (sample No. 1-4) is light yellow, and becomes white after potassium superoxide fully reacts with carbon dioxide to generate oxygen.
Embodiment 2
[0099] Mix dimethylpolysiloxane, methyltriacetoxysilane, dibutyltin dilaurate and calcium hydroxide with a viscosity of 100 mPas at room temperature and hydroxyl-terminated ends of the molecular chain at the contents shown in the following table 2 To prepare polymer compositions for air purification (sample Nos. 5-8). After the polymer composition is fully cured, it is stored in a desiccator filled with nitrogen.
[0100] Composition and content (embodiment 2) of each air cleaning sample of table 2
[0101]
Embodiment 3
[0103] Mix dimethylpolysiloxane, methyltriacetoxysilane, dibutyltin dilaurate and magnesium hydroxide with a viscosity of 100 mPas at room temperature and hydroxyl-terminated ends of the molecular chain at the contents shown in Table 3 below. To prepare polymer compositions for air purification (sample Nos. 9-12). After the polymer composition is fully cured, it is stored in a desiccator filled with nitrogen.
[0104] Composition and content (embodiment 3) of each air purification sample of table 3
[0105]
[0106] The polymer compositions in Example 2 and Example 3 (both containing stabilizer) changed from the light yellow color presented in Example 1 (without stabilizer) to cloudy.
