| titleOfInvention | A kind of preparation method of instant drilling fluid coating agent |
| abstract | The present invention relates to a kind of preparation method of instant drilling fluid coating agent, belong to coating agent preparing technical field.Fresh Microcystis aeruginosa is cleaned, dries and mill by the present invention first, obtain Microcystis aeruginosa powder, absolute ethyl alcohol extraction is recycled to remove the peel blue or green taro, collect to obtain blue or green taro extraction powder, its blue or green taro extraction powder is mixed with water again and after ultrasonic disperse, mixes with trimethylamine solution, sodium hydroxide solution, is reacted under the conditions of ice-water bath, modified powder is prepared into, the material such as Microcystis aeruginosa powder and modified powder is finally subjected to mixing and ball milling.Fast molten low viscosity type drilling fluid coating agent prepared by the present invention has the characteristic of low viscosity in use, is less prone to the phenomenon of flocculation, apparent viscosity is 25~29mPas, and plastic viscosity is 21~25mPas；Its rate of dissolution is fast, only needs 3~5min to be completely dissolved, accelerates construction speed, have broad application prospects. |
