Abstract

The invention discloses a preparation method of long-chain alkyl phenyl modified silicone oil including a catalyst, raw materials, technological conditions and an addition reaction technology. In the preparation method, Pt is taken as the catalyst, the technical proposal that hydrogen siloxane, long-chain carbon olefin and styryl hydrocarbon are taken as raw materials for the addition reaction is adopted, and the problems and defects existing in the preparation method in the prior art such as numerous steps, complex process, low efficiency, high cost, long period and unsuitability for mass production are overcome. The preparation method of long-chain alkyl phenyl modified silicone oil realizes the simplification of steps and process for preparing long-chain alkyl phenyl modified silicone oil and achieves the improvement of efficiency, reduction of cost and shortening of period, thus meeting the objective required for mass production.

Description

technical field [0001] The invention relates to the preparation of a lubricating grease base oil, in particular to a preparation method of a long-chain alkylphenyl modified silicone oil used as a release agent, a lubricant and a lubricating additive. Background technique [0002] Long-chain alkyl phenyl modified silicone oil is a new type of advanced mold release agent, lubricant, and lubricating additive. Compared with long-chain alkyl silicone oil, it has higher temperature resistance, higher refractive index, better transparency, and better lubricity. Good, the workpiece can be directly coated and printed without cleaning. It has good compatibility with petroleum hydrocarbons and resins. It is used in occasions that require higher mold release and lubrication performance. It has a wide range of uses. There is no long-chain alkanes in China Experiment or production process of phenyl modified silicone oil. The preparation of long-chain alkylphenyl modified silicone oil in ...
