With the emergence of waterborne polyurethane, waterborne alkyd resin, waterborne epoxy, waterborne fluorocarbon, waterborne silicone and a series of resins have greatly enriched the types and performance of waterborne coatings, especially solvent-free waterborne coatings, solving the problem of solvent-free to ensure the function of waterborne coatings, even in a closed environment can be safe construction. Among the many types of coatings, silicone coatings have gained widespread attention because of their special properties.
Organic silicone resin coatings are elemental organic coatings, or silicone coatings for short, using organic silicone resin or modified organic silicone resin as the main film-forming substance. Elemental organic coatings is a general term for coatings with elemental organic polymers as the main film-forming substances, including organosilicon, organotitanium, organofluorine, organoaluminum, organozirconium coatings and so on. Among them, silicone resin coating production is the largest. Elemental organic coatings are between organic polymers and inorganic compounds, with special thermal stability, insulation, high temperature resistance, chemical resistance, water resistance, weather resistance, etc., widely used in the defense industry, electrical industry and other industries.
Organic silicone resin has excellent thermal oxidation stability, weather resistance, electrical insulation, water repellency and corrosion resistance, has been widely used in high and low temperature insulating paints, special coatings, adhesives, film plastics and so on. However, at present, silicone resin high and low temperature insulating paint, silicone waterproof coatings and special coatings, etc. are mainly used aromatics, alcohols and other organics as solvents, which will produce a large number of VOC (Volatile Organic Compounds), the environment as well as the human body caused great harm, so the waterborne silicone resins is the current hot spot of the research and development trend.
Water-based silicone resin is a silicone resin water-based, water as a dispersing medium silicone resin emulsion, the current application of a wide range of silicone-modified coatings, such as silicone-modified acrylic emulsion, silicone-modified polyurethane emulsion, silicone-modified polyester emulsion and so on, the introduction of silicone into the traditional polymer emulsions, you can enhance the aging resistance, waterproofing, resistance to high and low temperatures, hardening and other properties. Through the process of emulsion polymerization, the introduction of silicone links in the molecular structure of polymers, commonly used silicone precursors for silane coupling agent, such as silane coupling agent 171, 560, 570, etc., these silane coupling agent are trifunctional alkoxy structure, in the aqueous system, alkoxy hydrolysis into hydroxyl, hydroxyl further dehydration and condensation, the formation of cross-linking structure, when the degree of cross-linking is too large will affect the stability of the emulsion, resulting in gelation. When the degree of crosslinking is too large, it will affect the stability of the emulsion, resulting in gelation, can not be used, so the dosage of silane coupling agent is a certain limit, the general dosage of 1 ~ 10%, the dosage is too small modification effect is not obvious, the dosage is too large to affect the stability of the emulsion, the dosage of the limitations of silicon modification decided to have a limitation of the effect of, or even is not obvious.
Furthermore, silane coupling agent hydrolysis reaction occurs in the water phase, by-products such as methanol, ethanol and other low molecular alcohols, is flammable and toxic components, for water-based coatings, it is VOC, and VOC is a water-based coatings strict control of the indicators, so silane coupling agent modified water-based coatings can not be a fundamental solution to solve the problem of low VOC and zero VOC, and ultimately will make the application of limitations.
The industrialization of solvent-free pure silicone resin emulsion just solves the above problem, 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 solid silicone resin, and then use a special emulsification process, solid silicone resin is 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, which is fundamentally green and zero VOC.
Solvent-free pure silicone resin emulsion can be made into room temperature curing, can also be heated curing, can be made into a two-component system can also be made into a one-component system, can be used directly or can be used in combination, fundamentally healthy, environmentally friendly, green, efficient, water-based coatings, a great innovation, solvent-free pure silicone resin emulsion has contributed to the rapid development of water-based coatings, can be said without modesty that the water paint ushered in the water-based silicone resin! It can be said without modesty that water paint has ushered in the era of water-based silicone resin!
