The invention relates to a phosphorization bolt
friction coefficient stabilizer and a preparation method thereof. The stabilizer comprises the following components in percentage by
mass: 10%-20% of
base oil, 6%-15% of
fatty acid, 8%-12% of
triethanolamine, 1%-2% of emulsifying agent, 0.5%-1% of bactericide, 3%-5% of
silicone oil and 48%-60% of
purified water, wherein various
machine oils and spindle oils are selected as the
base oil. The preparation method of the stabilizer comprises the following steps of: firstly adding a design amount of
base oil,
fatty acid and
silicon oil to a container, adding the
purified water for dissolving, then sequentially adding the
triethanolamine, the emulsifying agent, the bactericide and a defoaming agent according to proportioning, stirring, dissolving and filling a
volumetric flask, thus the phosphorization bolt
friction coefficient stabilizer can be used. The phosphorization bolt
friction coefficient stabilizer has good capacity of resisting oxidation,
acid gas, discoloration and dampness; a lubricating film formed on the surface of a phosphating film stabilizes the friction coefficient of a
fastener to be in the range of 0.06-0.09; and the friction coefficient of phosphorization bolts is controlled in the range of 0.075+ / -0.015, thus the effects of controlling the friction coefficient very well and resisting
corrosion are achieved.
