Embodiment Construction

[0011] The new "polyethylene" synthetic lubricating oil / lubricating oil additive developed by this patent is polymerized in a high-pressure reactor.

[0012] The first step is to prepare the catalyst for the polymerization of ethylene monomer in a vacuum glove box. All raw materials for the reaction must be dried to remove water and vacuumized to remove oxygen before use. Dissolve anhydrous aluminum chloride / titanium tetrachloride and treated nano silicon dioxide / aluminum trioxide / magnesium chloride powder in 10-100mL dehydrated toluene / chlorobenzene / dichloromethane / chloroform and other organic In the solvent, stir under nitrogen environment and slowly add a certain amount of diethylaluminum chloride / ethylaluminum dichloride solution, aluminum chloride / titanium tetrachloride and nano silicon dioxide / aluminum trioxide / The mass ratio of magnesium chloride is 0.5:1.0~4.0:1.0, the molar ratio of aluminum chloride / titanium tetrachloride to diethylaluminum chloride / ethylaluminum di...

Abstract

The invention relates to the technical field of chemical industry, in particular to novel 'polyethylene' synthetic lubricating oil / lubricating oil additive and a preparation method thereof. The preparation method includes one-step preparation of high-viscosity and low-molecular-weight polyethylene macromolecules, preparation of catalyst and synthesis of high-polymer materials. The preparation method has the advantages of simple synthesis, one-step completion, low catalyst cost, no pollution, promising application prospect in the field of lubricating oil, and the like. Products at different levels can be obtained through polyethylene macromolecules by adjusting preparation technical parameters. The novel new-generation polyethylene synthetic lubricating oil / lubricating oil additive is high in efficiency and applicable to the fields of lubricating oil and lubricating oil additives.

Description

technical field [0001] The patent of the present invention provides a highly efficient synthesis and preparation method of a new type of "polyethylene" synthetic lubricating oil / lubricating oil additive. The described invention includes the preparation of catalysts and the synthesis of polymeric materials. The obtained polymer material can be widely used as a synthetic lubricating oil in automobiles, aviation, and military fields, and can also be used as a lubricating oil additive to improve the performance of existing lubricating oils (such as stability, viscosity index, etc.). Background technique [0002] Lubricating oil is divided into three categories according to its source: moving oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil. Synthetic lubricating oils are made by replacing mineral base oils with esters (Easter) or poly-α-olefins (PAO, Poly-α-Olefin), and then blending them with additives. Due to its uniform and stable molecular struc...
