The invention discloses a kelp mucus drag reducer and a preparation method thereof, and belongs to the field of underwater drag reduction. The kelp mucus drag reducer comprises kelp mucus and sodium bicarbonate. The preparation method comprises the following steps: pretreating kelp serving as a raw material to obtain kelp mucus; adding sodium bicarbonate powder into the pretreated kelp mucus, adjusting the pH to make a weakly alkaline environment, and filtering by adopting a filter screen to obtain kelp mucus mother liquor; calculating the concentration of the kelp mucus mother liquor; according to the measured concentration of the kelp mucus mother liquor, the kelp mucus mother liquor is dried and concentrated or diluted with water, and the kelp mucus drag reducers with different concentrations are prepared through sufficient stirring. The problems that an existing drag reducer preparation method is tedious and unfriendly to the environment are solved.

    本发明一种海带黏液减阻剂及其制备方法,属于水下减阻领域;所述海带黏液减阻剂包括海带黏液和碳酸氢钠。制备方法步骤为:将海带作为原料进行预处理,得到海带黏液;将预处理后的海带黏液加入碳酸氢钠粉末,调节ph制造弱碱性环境,采用滤网过滤得到海带黏液母液;对海带黏液母液浓度进行计算;根据测得的海带黏液母液浓度,对海带黏液母液进行烘干浓缩或者加水稀释,充分搅拌配置成不同浓度的海带黏液减阻剂。本发明解决了现有减阻剂制备方法繁琐、对环境不友好的问题。
