First, the waterborne silicone resin is mainly a silicone resin emulsion with water as the dispersing medium, and the current application focuses on silicone-modified coatings, such as silicone-modified acrylic emulsions, silicone-modified polyurethane emulsions, silicone-modified polyester emulsions and so on. The introduction of silicone in traditional polymer emulsions can enhance their aging resistance resistance, waterproofing, high and low temperature resistance, hardening and other properties. By introducing silicone links into the molecular chain of the polymer during emulsion polymerization, the commonly used silicone precursors are silane coupling agents, such as silane coupling agents 171, 560, 570, etc.. These silane coupling agent are trifunctional alkoxy structure, in the aqueous system alkoxy hydrolysis into hydroxyl, hydroxyl further dehydration condensation, the formation of crosslinked structure, when the degree of crosslinking is too large, it will affect the stability of the emulsion, resulting in gelation, can not be used, so for the dosage of the silane coupling agent is a certain limitation, the general dosage of 1 ~ 10%, the dosage is too small to modify the effect is not obvious, too large an impact on the stability of the emulsion, the amount of dosage is too large, the stability of the emulsion. Emulsion stability, the dosage limit determines the effect of silane modification is limited, or even not obvious. Furthermore, the hydrolysis reaction of silane coupling agent occurs in the aqueous phase, the by-production of methanol, ethanol and other low molecular alcohols, which are flammable and toxic components, for water-based coatings, it is VOC, and VOC is a strictly controlled indicator of water-based coatings, so silane coupling agent modified water-based coatings can not be a fundamental solution to the problem of low VOC and zero VOC, which will ultimately lead to the limitation of the application.
Second, solvent-free pure silicone resin emulsion can solve the above problems. Solvent-free pure silicone resin is the silane coupling agent pre-hydrolysis condensation of solid silicone resin, the solid silicone resin does not contain alkoxy, to avoid the release of alcohols in the use of the process, and then use a special emulsification process, the solid silicone resin uniformly dispersed in the water, the formation of a stable emulsion. Solvent-free pure silicone resin avoids both the introduction of solvents and the release of by-product solvents, and is fundamentally green and zero VOC. in terms of application, solvent-free pure silicone resin emulsion can be dissolved with acrylic emulsion, polyurethane emulsion, polyester emulsion, alkyd emulsion, fluorocarbon emulsion, wax emulsion, and other emulsions in any proportion, without special production process, as long as the dispersion is uniform to be used, and it won't result in It can be used without special production process as long as it is evenly dispersed, and will not cause gel or emulsion breakage. Solvent-free pure silicone resin emulsion retains all the properties of solvent-based silicone resin, and can also be used to formulate special functional coatings, such as silicone heat-resistant coatings, silicone weather-resistant coatings, silicone insulating coatings, silicone elastic coatings, silicone waterproof coatings and so on.
Solvent-free pure silicone resin emulsion can be used directly as varnish, and it can be used directly in occasions requiring high transparency, such as wood paint, which has higher hardness, water resistance and anti-staining properties than the existing acrylic emulsion and polyurethane emulsion without covering the surface shape and grain of the substrate or even affecting the luster, and it has been successfully applied in waterproofing and protection of concrete, stone, stone wool, clay, timber, paper, cultural relics and metal, as well as water-in-water (sand) protection and water-in-water (sand) protection. It has been successfully applied to waterproofing of concrete, stone, rock wool, clay, wood, paper, cultural relics, metal, etc. as well as water-in-water (sand), real stone paint, etc.
