Breakthrough in dimethyl silicone oil emulsion technology: The problem of high-viscosity emulsification is easily solved

1.The technical bottleneck of emulsifying high-viscosity silicone oil has been broken through
For a long time, high-viscosity dimethyl silicone oil with a viscosity greater than 10,000 CP has been difficult to be uniformly dispersed in the aqueous phase to form a stable emulsion due to its strong intermolecular forces. This technical bottleneck has restricted its application in high-end fields such as precision optical polishing and electronic wafer processing. Recently, a research team has successfully developed a high-viscosity dimethyl silicone oil emulsion that is easy to emulsify by compounding high-molecular amphoteric surfactants with isomer alcohol polyoxyethylene ethers. This has solved the problem of requiring high-temperature and high-pressure equipment in traditional processes, simplifying production equipment and reducing operating costs. This technological breakthrough not only enhances the stability of silicone oil emulsion but also enables it to be stored at room temperature for 12 months without stratification, which is significantly superior to traditional products.

2. Synergistic effect of new compound surfactants
The core of this innovation lies in the molecular design of amphoteric surfactants. Polymers with both hydrophilic and lipophilic functional groups are formed by copolymerizing macromolecular monomers with acrylic acid and dimethylaminoethyl methacrylate. When compounded with isomer alcohol polyoxyethylene ether, the two surfactants reduce the interfacial tension through a synergistic effect, causing the high-viscosity silicone oil to disperse in the aqueous phase into uniformly sized tiny droplets (with an average particle size of less than 1 micron), forming a semi-transparent emulsion with blue light. This emulsion can not only be diluted with water in any proportion, but also be well compatible with other emulsions, expanding its applicability in different industrial scenarios.

3. The revolution of efficient demolding and lubrication in the industrial field
In the production of rubber products, dimethyl silicone oil emulsion shows significant advantages as a mold release agent. The uniform lubricating film it forms can reduce the adhesion force between the rubber and the mold, increase the demolding efficiency by more than 30%, and at the same time reduce the product damage and mold cleaning time caused by adhesion. In addition, the application of this emulsion in fields such as moisture-proof coatings for electronic components and automotive polishing agents further highlights its multi-functionality in industrial lubrication, insulation protection, and other aspects. It is worth noting that its low volatility (VOC content less than 0.1%) and non-toxicity make it an environmentally friendly alternative to traditional petroleum-based lubricants.

4. Market prospects and environmental protection advantages
According to industry forecasts, the market size of dimethyl silicone oil emulsion in China is expected to exceed 1.4 billion yuan by 2025, with an average annual compound growth rate of 10%, among which the demand growth rate for high-viscosity products is particularly significant. With the tightening of environmental protection policies, application cases of this emulsion in fields such as degradable coatings and water-based paints are constantly emerging. For instance, the environmentally friendly aqueous hydrophobic emulsion prepared by the silane coupling agent hydrolysis technology can form a firm hydrophobic coating on the surface of textiles, replacing traditional fluorine-containing materials, and achieving the functions of water and stain resistance while reducing the environmental burden. This technological innovation not only promotes the green transformation of industrial production but also opens up a broader market space for dimethyl silicone oil emulsion.
