Paint science: water paint, ushered in the era of water-based silicone resin!

In the environment of environmental protection, the waterization of domestic coatings is developing at an unprecedented rate, and the coating industry is accelerating the "water-based" landscapeCompared with solvent-based coatings, water-based coatings can save a lot of resources, eliminate safety hazards, improve the working environment of construction personnel, reduce air pollution, more conducive to human healthIn addition, the performance of water-based coatings is not worse than solvent-based coatings, the effect after construction is more natural, rich, is a "coating" in the history of a bright spot, but also today's paint industry well-deserved darlingwith the emergence of a series of resins such as water-based polyurethane, water-based alkyl acid resin, water-based epoxy, water-based fluorocarbon, water-based silicone, etc., which greatly enriched the types and properties of water-based coatings, especially the advent of solvent-free water-based coatings, and solved the problem of ensuring the function of water-based coatings under solvent-free conditions, even in closed environments can be safely constructedAmong the many coating types, silicone coatings have received wide attention because of their special propertiesoverview of silicone resin coatings
silicone resin coating is based on silicone resin or modified silicone resin as the main film material, is an elemental organic coating, referred to as silicone coatingElemental organic coating is a coating by elemental organic polymer as the main film material, including silicone, organic titanium, organic fluorine, organic aluminum, organic tantalum coatingAmong them, silicone resin coating production is the largestElemental organic coating is a compound between organic polymer and inorganic compounds, with special thermal stability, insulation, high temperature, chemical resistance, water resistance, weather resistance and so on, widely used in the defense industry, electrical industry and other industriessilicone generally refers to polysiloxane with -Si-O-Si-primary key and organic base side chainPolysiloxane has the properties of inorganic silica, safe and reliable, non-toxic, non-polluting, non-corrosive, anti-aging and long-life, because the main chain is -Si-O-Si-structure, and has the flexibility and easy processing characteristics of high molecular materials because the side chain contains machine groupsSilicone coating is a silicone polymer or silicone modified polymer as the main film-based coating, with excellent heat and cold resistance, electrical insulation, corona resistance, radiation resistance, moisture and water resistance, weather resistance, stain resistance and chemical corrosion resistance and other characteristicssolvent-free pure silicone emulsion and water-based silicone resin special functional coatings
silicone resin with excellent thermal oxidation stability, weather resistance, electrical insulation, water repellent and corrosion resistance, has been widely used in high and low temperature insulation paint, special coatings, adhesives, membrane plastics and so onHowever, the current silicone resin resistance to high and low temperature insulation paint, silicone waterproof coatings and special coatings and other organic compounds such as aromatics, alcohols as solvents, will produce a large number ofVOC (volatile organic compounds), the environment and the human body caused great harm,silicone resin hydracy is currently a hot research and development trendwater-based silicone resin is a silicone resin hydration, water as a dispersed medium of silicone emulsion, currently widely used in silicone modified coatings, such as silicon modified acrylic emulsion, silicon modified polyurethane emulsion, silicon modified polyester emulsion, etc, in the traditional polymer emulsion introduced silicone, can enhance its resistance to aging, waterproof, high temperature, hard and so onBy introducing silicone chain joints into the molecular structure of the polymer polymer in the emulsion polymer polymer polymer, the commonly used silicone precursor is silane coupling agents, such as silane coupling agent 171,560,570, etc., these silane coupling agents are tri-functional hydroxylstructures, hydroxyhydroxyl solutions in the hydrophase system, hydroxyl Step dehydration contraction, the formation of cross-linking structure, when the degree of crosslinking will affect the stability of emulsion, resulting in gel, can not be used, so the amount of silane coupling agent is limited, the general amount of 1 to 10%, the amount of too small modification effect is not obvious, the amount of too large impact on the stability of the emulsion, the amount of restrictions determine that the effect of silicon modification is limited, even not obvious, silane conjugate agent in the water phase hydrolysis reaction, by-product methanol, ethanol and other low molecular alcohols, is flammable toxic components,for water-based coatings, it is VOC, and VOC is a water-based coating strictly controlled indicators, so silane-conjugate agent modified water-based coatings can not fundamentally solve the problem of low VOC and zero VOC, will eventually limit the applicationthe industrialization of solvent-free pure silicone emulsion just solves the above problem, solvent-free pure silicone resin is a pre-water deconstructed solid silicone resin, the solid silicone resin does not contain alkyd, avoids the use of mid-alcohol release, and then uses a special emulsification process,solid silicone resin evenly dispersed in water, forming a stable emulsionSolvent-free pure silicone resin not only avoids the introduction of solvents and the release of side-product solvents, and fundamentally achieves green environmental protection, zero VOCin the application, solvent-free pure silicone emulsion can be with acrylic emulsion, polyurethane emulsion, polyester emulsion, alkyl resin emulsion, fluorocarbon emulsion, wax emulsion and other emulsions in any proportion, without special production process, as long as the dispersion can be used, will not cause gel, broken emulsion, silicone composition of the infinite introduction can maximize the performance of silicone, can be formulated to make full use of siliconesolvent-free pure silicone emulsion can also be used directly as varnish, the transparency requirements of the occasion can be used directly, such as wood paint, in the absence of covering the surface of the substrate, texture or even does not affect the gloss at the same time, with higher hardness than the existing acrylic emulsion, polyurethane emulsion, anti-staining, has been successfully applied to concrete, stone, rock wool, clay, wood, paper, cultural relics, metal and other waterproof protection and water coatingsolvent-free pure silicone emulsion retains the properties of solvent-based silicone resins, the same can be formulated special functional coatings, such as silicone heat-resistant coatings, silicone weather-resistant coatings, silicone insulation coatings, silicone elastic coatings, silicone waterproof coatings, for environmental protection requirements are getting higher and higher today, water-based special functional coatings undoubtedly have a broader space for developmentsolvent-free pure silicone 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 single component system, can be used directly or re-use, fundamentally achieve a healthy, environmentally friendly, green, efficient, water-based coating is a great innovation, solvent-free pure silicone emulsion to promote the rapid development of water-based coatings, can not be modest water paint ushered in the
