Abstract

The invention relates to the technical field of drag reduction agents, and provides a poly-alpha-olefin drag reduction agent and a preparation method thereof. The poly-alpha-olefin drag reduction agent comprises alpha-olefin, solvent, a Ziegler-Natta catalyst and gas, wherein the gas is ethylene or propylene gas. The preparation method comprises the following steps: adding the Ziegler-Natta catalyst into the alpha-olefin and solvent in a nitrogen gas protective atmosphere, performing polymerization reaction on the long-chain olefin part, then introducing the ethylene or propylene gas, and performing binary copolymerization reaction to obtain the poly-alpha-olefin drag reduction agent. Thus, the poly-alpha-olefin drag reduction agent has the characteristics that the ethylene or propylene gas raw material is less prone to self polymerization in the reaction and is cheap and accessible, and the obtained poly-alpha-olefin drag reduction agent is high in drag reduction rate; and the production cost is lowered, and the shearing resistance is improved.

Description

technical field

[0001] The invention relates to the technical field of drag reducers, and relates to a polyalpha-olefin drag reducer and a preparation method thereof. Background technique

[0002] Drag reducer is a chemical additive that can reduce the friction of liquid flow. The polymer molecules are stretched in the fluid. Due to its deformation or orientation, it absorbs the turbulent energy and reduces the energy loss in the flow process. Therefore, the oil When the product is transported in the pipeline, adding drag reducing agent can play the role of increasing transportation and saving energy.

[0003] The drag reduction phenomenon of high molecular polymers has been studied by Toms in the 1940s. In the 1960s, many researchers from all over the world proposed various synthesis methods of drag reducers and applied for patents. It was not until 1979 that the drag reducer produced by the American Conoco Company was applied in industrial production. The oil-soluble dra...
