Further, the wax anti-rust spray can be filled into an aerosol can, the used propellant is LPG, wherein the ratio of stock solution in the aerosol can: LPG 1: 3.
a preparation method of a waxy antirust spray comprises the following steps:
(1) adding microcrystalline wax into n-heptane, and dispersing for 10 minutes in a dispersion machine at 4000r/min to completely dissolve and disperse the microcrystalline wax in the n-heptane to obtain stock solution;
(2) adding sorbitan fatty acid ester, lanolin pentaerythritol ester, barium dinonylsulfonate and base oil into the dispersed stock solution, and adjusting a dispersion machine to a stirring speed of 800r/min to continuously stir for 5 minutes until the mixture is uniform;
(3) filling the stock solution into aerosol cans, wherein the stock solution in each can is as follows: LPG is 1:3 (mass ratio), the aperture of the packaging spray head is 0.46mm, and a two-way valve is adopted.
As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following advantages: the microcrystalline wax is composed of cyclane and aromatic hydrocarbon which have larger molecular weight and longer carbon chains, the crystallization is needle-shaped or granular, the hardness is small, the toughness is good, and the film formation is relatively more uniform; the sorbitan fatty acid ester is a high-grade lipophilic emulsifier, so that the wax emulsion can be kept stable, the adhesive force of the wax film can be obviously improved, and the wax film can be uniformly attached to the mold and is not easy to be stripped in a blocking manner; lanolin pentaerythritol ester and barium dinonylsulfonate are used as main antirust components, and ester low-viscosity base oil enhances the antirust effect and reduces the wiping removal difficulty; the n-heptane is easy to volatilize, so that the wax film can be quickly dried on a mould device to form a film. The manufacturing process of the invention does not need to be carried out in a high-temperature and high-pressure environment, the cost is saved, the energy consumption is also saved, the antirust film is not flowable, the antirust performance is strong, the antirust effect is obvious particularly in marine transportation, and the cleaning is simple.
