1. The water-based silicone resin is mainly a silicone resin emulsion using water as the dispersion medium. Currently, its application is focused on silicone-modified coatings, such as silicon-modified acrylic emulsion, silicon-modified polyurethane emulsion, silicon-modified polyester emulsion, etc. Introducing silicone into traditional polymer emulsions can enhance its aging resistance, waterproofing, high and low temperature resistance, hardening and other properties. By introducing silicone links into the molecular chain of the polymer during the emulsion polymerization process, the commonly used silicone precursors are silane coupling agents, such as silane coupling agents 171, 560, 570, etc. These silane coupling agents all have trifunctional alkoxy structures. In the aqueous system, the alkoxy groups are hydrolyzed into hydroxyl groups, and the hydroxyl groups are further dehydrated and condensed to form a cross-linked structure. When the degree of cross-linking is too large, it will affect the stability of the emulsion. It causes gelation and cannot be used. Therefore, there are certain restrictions on the amount of silane coupling agent. Generally, the amount is 1~10%. If the amount is too small, the modification effect will not be obvious. If the amount is too large, the stability of the emulsion will be affected. Dosage The limitation determines that the effect of silicon modification is limited or even not obvious. Furthermore, the silane coupling agent undergoes a hydrolysis reaction in the water phase, and the by-products are methanol, ethanol and other low molecular alcohols, which are flammable and toxic components. For water-based coatings, they are VOCs, and VOCs are strictly controlled by water-based coatings. Index, so water-based coatings modified with silane coupling agents cannot fundamentally solve the problem of low VOC and zero VOC, and will eventually limit their application.


2. Solvent-free pure silicone emulsion can solve the above problems. Solvent-free pure silicone resin is made by pre-hydrolysis and condensation of silane coupling agent into solid silicone resin. This solid silicone resin does not contain alkoxy groups, which avoids the release of alcohol during use. Then a special emulsification process is used to convert the solid silicone resin into solid silicone resin. The resin is evenly dispersed in water to form a stable emulsion. Solvent-free pure silicone resin avoids the introduction of solvents and the release of by-product solvents, and is fundamentally green and environmentally friendly with zero VOC. In terms of application, solvent-free pure silicone emulsion can be miscible with acrylic emulsion, polyurethane emulsion, polyester emulsion, alkyd resin emulsion, fluorocarbon emulsion, wax emulsion and other emulsions in any proportion. No special production process is required, as long as they are evenly dispersed Ready to use without causing gel or emulsification. Solvent-free pure silicone resin emulsion retains the properties of solvent-based silicone resin, and can also be formulated with special functional coatings, such as silicone heat-resistant coatings, silicone weather-resistant coatings, silicone insulating coatings, silicone elastic coatings, and silicone waterproof coatings wait.
Solvent-free pure silicone resin emulsion can be used directly as varnish, and can be used directly in situations that require high transparency, such as wood paint. While not covering the surface morphology, texture, or even affecting the gloss of the substrate, it is more efficient than existing acrylic emulsions. Polyurethane emulsion has higher hardness, water resistance, and anti-fouling properties, and has been successfully used in waterproof protection of concrete, stone, rock wool, clay, wood, paper, cultural relics, metals, etc., as well as water-in-water (sand), real stone paint, etc. Wall finish varnish.
