The invention provides preparation and application of
protein lubricating liquid, and relates to the field of
protein lubricating liquid. The preparation and application of the
protein lubricating liquid comprise the following steps: S1, adding water and
glycerol into a stirring pot, and stirring; s2, after uniformly stirring, sequentially adding
hyaluronic acid,
egg white powder, 1, 2-hexanediol and
raspberry ketone; s3, heating the stirring pot, performing stirring, and performing heat preservation after uniform stirring; s4, keeping the temperature for a certain time, slowly stirring and cooling to
room temperature; and S5, adding rose
essential oil, and slowly stirring to obtain the protein lubricating liquid. In the invention, natural
egg white is adopted as a main
raw material to prepare the protein lubricating liquid, and the protein lubricating liquid is prepared from a transparent colloidal substance consisting of proteins and contains rich protein components including 75% of
ovalbumin, 15% of ovomucoid, 7% of ovomucoprotein and 3% of concomitant
albumin, so that the lubricating liquid has the advantages of desugaring, fishy smell removal, high purity, rapid
dissolution and the like.
