Long chain alkyl silicone oil, which is mainly modified by the addition of long chain carbenes and hydrogen containing silicone oil; It has excellent lubricity, demould, hydrophobicity, antifouling, coating and good compatibility with organic polymers. Long chain alkyl silicone oil especially for poor lubricity of aluminum, zinc, copper has a good lubrication effect. Long chain alkyl silicone oil can also be used in plastic release agent, fiber lubricant, preparation of aircraft, military vehicles and machinery used in the cold zone of high flash point hydraulic transmission fluid. The impact strength of polypropylene can be greatly improved by adding a small amount of long chain alkyl silicone oil. A small amount of this product is added to crude oil to effectively reduce its freezing point.
1, in the mechanical and electrical industry application: long chain alkyl silicone oil is widely used in motors, electrical appliances, electronic instruments as temperature resistance, arc corona resistance, corrosion resistance, moisture-proof, dustproof insulating medium, is also used as transformer, capacitor, TELEVISION scanning transformer dipping agent. In a variety of precision machinery, instruments and instruments, used as liquid shock, damping material. The damping performance of long chain alkyl silicone oil is less affected by temperature, and it is mostly used in situations with strong mechanical vibration and large environmental temperature change. The instruments used, such as: aircraft, automobile instruments. Used for shock, damping, stabilizing instrument readings and as a liquid spring in aircraft landing gear.
2, for defoaming agent: Because of the long chain alkyl silicone oil surface tension is small, and insoluble in water, animal and plant oil and high boiling point in the mineral oil, good chemical stability, and non-toxic, used as a defoaming agent has been widely used in petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, paper making industries, as long as add 10-100 parts per million of silicone oil has good defoaming agent.
3, as a release agent: because of the long chain alkyl silicone oil and rubber, plastic, metal and other non-viscous, and used for all kinds of rubber, plastic products molding processing release agent, and used in precision casting. It is not only convenient to use it as a release agent, and make the surface of the product clean, smooth, clear texture.
4, for insulation, dustproof, mildew-proof coating: in the glass, ceramic surface dip coated with a layer of long chain alkyl silicone oil, and heat treatment at 250-300℃, can form a layer of semi-permanent waterproof, mildew-proof and insulating film. It can improve the insulating performance of the device. It can prevent the lens and prism from mildew when it is used to treat the optical instrument. With the treatment of medicine bottle, can prolong the storage period of medicine, do not make the preparation due to adhesion and loss; It can be used to lubricate the surface of film, reduce friction and prolong the life of film.
5, as a lubricant: long chain alkyl silicone oil is suitable for rubber, plastic bearing, gear lubricant. It can also be used as a lubricant for rolling friction between steel and steel at high temperature, or friction between steel and other metals, but because the lubrication performance of methyl silicone oil is not particularly good at room temperature, in general, it is not recommended as a lubricant between metals at room temperature.
6, as an additive: Long chain alkyl silicone oil can make many material additives, such as whitening agent can be used as paint, add a small amount of silicone oil into the paint, can make the paint is not foam, not wrinkle improve the brightness of paint film is, add a small amount of long chain alkyl silicone oil into the ink, can improve the quality of printing, add a small amount of long chain alkyl silicone oil to the polishing oils (such as car glazing oil), can increase the brightness, protective film, And has excellent waterproof effect
