What is the role of water soluble silicone oil in life?

1. Water-soluble silicone oil is used as a leveling agent for paints and polyurethane slurries, which can reduce the internal friction and stress of its molecules, thereby playing the role of leveling and defoaming.

2. The cosmetics industry is used to make cream products, and water-soluble silicone oil has lubricating and moisturizing and anti-wrinkle effects.

Third, it is the key ingredient in the preparation of self-emulsifying defoamer and delayed coking defoamer in the oil refining industry.

Fourth, it is used to make high-efficiency cutting fluid and high-grade cleaning agent. It is used as a foaming agent for foaming rigid polyurethane system to make the bubble pores fine and uniform.

5. It can be added to plastics as an internal additive, and water-soluble silicone oil is used to produce drip-free film greenhouses to prevent fogging and improve light transmittance.

The role of silicone oil is to dilute and lubricate. There are two types of uses: lubrication and lubrication improvement.

When used for lubrication, it is commonly used as high-grade lubricating oil, shockproof oil, insulating oil, defoamer, release agent, polishing agent, separator and vacuum diffusion pump oil; The emulsion can be used for car tire varnishing, dashboard varnishing, etc.

When used to improve lubrication, such as methyl silicone oil after emulsification or modification, it is used for smooth and soft hand finishing on textile finishing, and emulsified silicone oil is also added to the shampoo of daily care products to improve the lubrication of hair.

Advantages of silicone oil.

1. The viscosity temperature performance is the best among liquid lubricants, and the viscosity changes little in a wide temperature range. Its freezing point is generally less than 50, some as high as 70, long-term storage at low temperature, the appearance and viscosity of its oil have no change, it is a base oil with high temperature, low temperature and wide temperature range.

2. Excellent thermal oxidation stability, such as thermal decomposition temperature 300, small evaporation loss (150, 30 days, evaporation loss is only 2%), oxidation test h), viscosity and acid value change small.

3. Excellent electrical insulation, volume resistance, etc. do not change within the range of 130 at room temperature (but no water can be contained in the oil).

4. It is a non-toxic, low foaming and strong anti-foaming oil, which can be used as a defoamer.

Hydrosilicone oil has excellent hydrophobicity and is suitable for surface treatment of glass, metal, fiber, powder and many other occasions.

This product can be cross-linked into a film at low temperature under the action of metal salt catalysts, forming a waterproof film on the surface of various substances, and can be used as a waterproofing agent for fabrics, glass, ceramics, paper, leather, metal, cement, marble and other materials, especially for waterproofing fabrics. Methyl hydrosilicone oil emulsion is used in conjunction with methyl hydroxysilicone oil emulsion, which can be waterproof and maintain the breathability of the fabric, and can improve the tear strength, friction strength and stain resistance of the fabric, and improve the hand feel and sewing performance of the fabric. In addition, it is used as an anti-stick separator and cross-linking agent for paper.

1. Solid silicone rubber - high-temperature mixed silicone rubber (HTV) is used as a bridging agent, anti-yellowing agent, and coupling agent.

2. It is used as a crosslinker for addition molding liquid silicone rubber, and Si-C bonds are formed under the catalytic action of PT.

3. In waterproof clothing and waterproof gypsum board, it can be used as a waterproof agent (water repellent agent, water repellent agent), and under the action of metal salt catalysts, it can be cross-linked to form a film at low temperature to form a waterproof film on the surface.

4. In the surface treatment of MGO (electrical grade MGO), it plays an insulating role.

5. In the textile and garment industries, it is used as a softener, a water-repellent agent, a hand feel improver, a lubrication of sewing threads, a lubrication of chemical fiber spinnerets and a clothing lining auxiliary.

Silicone oil has a wide range of applications, it is not only used as a special material in aviation, cutting-edge technology, military technology departments, but also used in various sectors of the national economy, and its application scope has been expanded to: construction, electronic and electrical, textile, automobile, machinery, leather and paper, chemical light industry, metals and paints, medicine and medical treatment, etc.

The main applications of silicone oil and its derivatives are release agents, shock absorbing oils, dielectric oils, hydraulic oils, heat transfer oils, diffusion pump oils, defoamers, lubricants, hydrophobic agents, paint additives, polishing agents, cosmetics and daily necessities additives, surfactants, granular and fiber treatment agents, silicone grease, and flocculants.
