Abstract

The invention provides an organic silicon modified fluorinated polyacrylate emulsion, a preparation method thereof, a prepared unconventional energy drilling and production coating and application thereof, and relates to the technical field of unconventional energy drilling and production coatings. The preparation method specifically comprises the following steps: heating and uniformly mixing lauryl methacrylate, perfluoropolyether methacrylate, vinyltriethoxysilane and n-butyl methacrylate, adding an emulsifier to prepare a pre-emulsion, adding an initiator in batches, and heating for reaction to obtain the organic silicon modified fluorinated polyacrylate emulsion. And the organic silicon modified fluorine-containing acrylate is copolymerized with styrene and toluene to obtain the organic silicon modified fluorine-containing acrylate unconventional energy drilling and production coating. Through detection, the coating has excellent hydrophobic scale inhibition performance and good bonding strength, the adhesive force of the coating to a metal substrate can be greatly improved, and the coating has the advantages of high bonding capacity, high surface hardness and good wear resistance and scrubbing resistance. The preparation process is simple to operate and low in energy consumption, the production process is easy to control, and large-batch continuous production can be realized.

Description

Technical field [0001] The present invention is the field of unconventional energy diamonds and coating technology. It involves a kind of silicon -alternative fluorine polyacrylate emulsion and its preparation methods, unconventional energy diamonds and applications. Background technique [0002] In the process of unconventional energy mining, such as combustible ice, geothermal energy, shale gas, etc. are usually stored in the sandy quality of the bottom layer of the sea, compared with conventional energy (such as crude oil mining) The inevitable collision with the transportation equipment caused the wear of the coating, causing the equipment to be corroded and damaged. Therefore, equipment coatings should have excellent abrasion resistance, corrosion resistance and stronger hardness. [0003] Acrylic polymers have excellent light stability, weather resistance, and good water resistance, alkali resistance, chemical resistance, heat resistance and cold resistance, etc., but its s...
