Embodiment 1
[0015] A muddy water spacer for automobiles, said spacer comprises the following components according to weight percentage: 5% of nuciferine, 3% of citric acid, 6% of malic acid, 3% of gluconic acid, 5% of oxalic acid, 8% of succinic acid, Sodium dodecylbenzenesulfonate 2%, ethylenediaminetetraacetic acid 4%, glycerin 0.1%, water 63.9%.
Embodiment 2
[0017] A mud-water spacer for automobiles, said spacer comprises the following components according to weight percentage: 8% of nuciferine, 6% of citric acid, 10% of malic acid, 8% of gluconic acid, 8% of oxalic acid, 12% of succinic acid, Sodium dodecylbenzenesulfonate 3%, ethylenediaminetetraacetic acid 5%, glycerin 0.15%, water 39.85%.
Embodiment 3
[0019] A muddy water spacer fluid for automobiles is prepared by the following method:
[0020] (1) The weight fractions are respectively: each component of nuciferine 5%, citric acid 3%, malic acid 6%, gluconic acid 3%, oxalic acid 5%, succinic acid 8% is dissolved in the water of 63.9% by weight ;
[0021] (2) Heat the mixed solution obtained in step (1) to 90° C. through an alcohol lamp, and keep at the temperature for 10 minutes;
[0022] (3) The temperature of the mixed solution obtained in step (2) is down to 30° C., then add 2% by weight of sodium dodecylbenzenesulfonate, 4% by weight of ethylenediaminetetraacetic acid and 0.1% by weight of glycerol , stirring and mixing evenly to obtain the spacer liquid.
