| Low temperature storage stability, 3 times | Without caking | Without caking | Without caking | Without caking | Without caking |
| Drying time (surface drying) min | 30 | 42 | 36 | 42 | 45 |
| Weather resistance (96h) | Is excellent in | Is excellent in | Is excellent in | Is excellent in | In general |
| Alkali resistance (96h) | No abnormality | No abnormality | No abnormality | No abnormality | In general |
| Water resistance (96h) | No abnormality | No abnormality | No abnormality | No abnormality | In general |
| Standard viscosity Strength (MPa) | 1.25 | 1.16 | 1.20 | 1 21 | 1.18 |
| Adhesion Property | Is excellent in | Is excellent in | Is excellent in | Is excellent in | Is excellent in |
| Stability in thermal storage | No abnormality | No abnormality | No abnormality | No abnormality | No abnormality |
From the above experiments, it can be concluded that when the silica sol: when the emulsion is 1:4, the water resistance, alkali resistance and adhesive force of the stone-like paint are obviously improved.
The invention relates to the following principle:
the silica sol inorganic paint is developed in recent years, during the drying and film forming process, monomer silicic acid is gradually polymerized into high polymer silica gel, colloid molecules are increased, a three-dimensional Si-O-Si bond coating film is formed, the water resistance and the heat resistance of the paint are obviously superior to those of organic paints, and the paint has outstanding anti-contamination capability, and the effect is just the defect of the emulsion.
The particle size of the silica sol is generally less than 100 nm. When the particle size is less than 8 nm. The water resistance is reduced linearly, the phenomenon of foaming of water bubbles occurs, when the particle size is more than 40nm, the storage stability is poor, and the film forming effect is weakened, so that the silica sol generally adopted by the building coating is between 8 and 20 nm.
The main formula is as follows:
although only the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art, and all changes are encompassed in the scope of the present invention.
