| titleOfInvention | Drag reducing polymers and oil dispersions |
| abstract | This invention relates to an oil-based suspension-dispersion system of drag reduction polymers and the method for preparing same. It is characterized in adding 0.001-0.1 wt% of ultraviolet absorber and 0.001-0.1 wt% of bactericide into 50-90 wt% of vegetable oil and then mixing the obtained mixture to be homogeneous for use as dispersant, adding 2-25 wt% of separant into 10-40 wt% of extra-high-molecular a-olefinstyrene polymer based drag reduction polymer and crushing them into powders at a temperature of lower than -90{C. based on the total weight of the suspension-dispersion system, and then adding the obtained mixture into the dispersant and stirring the mixture by using a high speed emulsion machine to make the mixture homogeneous and emulsified. The dispersion per se is also claimed. In addition to a low viscosity of the suspended dispersion system, this invention offers a high solid content up to 35%; improves the high temperature resistance performance of the drag reduction polymer to enlarge its operational range to 10-70{C; significantly raises the flash point of drag reduction polymers and improves the safety properties of drag reduction polymers during transportation and storage; eliminates the odour of the alcoholic suspended dispersion system and improves the operating environment; and offers good stability so that the suspended dispersion system can be stably stored for more than six months. |
