Abstract

The invention discloses a preparing method for a manganese series phosphatisation surface conditioning agent. The preparing method includes the following steps that firstly, 35 parts of anhydrous sodium hydrogen phosphate is prepared into a water solution with the concentration being 55%; secondly, 1-2 parts of N-methyl pyrrolidone, 0.4 part of titanyl sulfate, 4.3 parts of sodium pyrophosphate, 3.8 parts of sodium bicarbonate, 0.7 part of sodium tetraborate, 2.1 parts of sodium tripolyphosphate, 0.3 part of polycarboxylic acid anion organic matter and 0.9 part of lauroyl aminoethyl sodium sulfate are sequentially added into the water solution of the sodium hydrogen phosphate, and a mixed solution is obtained; thirdly, the mixed solution is heated to 75 DEG C and sufficiently stirred, and white powder with the water content below 2% is obtained; fourthly, the powder is stirred continuously at the temperature being 80 DEG C, 0.9 part of sodium pyrophosphate, 1.2 parts of glacial acetic acid, 0.4 part of methyl triethoxysilane and 1.7 parts of magnesium sulfate are added into the powder at the same time, and stirring and drying are conducted continuously till the water content is smaller than 1%. The surface conditioning agent prepared through the preparing method is good in dispersion stability and capable of being stored for a long time.

Description
