[0014] The beneficial effects of the present invention: (1) The present invention adopts a three-layer wiping wet wipe composed of a rust prevention wiping layer, an intermediate functional layer, and a cleaning wiping layer. When in use, the cleaning wiping layer can be used to scrub the weapon equipment to remove dust and debris first; after the scrubbing is completed, the rust prevention wiping layer of the wiping wet wipe can be used to wipe the weapon equipment for rust prevention; among them, the intermediate functional layer can heat the wiping wet wipe during use, and the hot towel can quickly dissolve stubborn oil stains, grease, and gum-like dirt through the temperature increase, effectively improving the scrubbing efficiency of the wiping wet wipe. Moreover, the self-heating wiping wet wipe makes it suitable for the wiping work of weapon equipment under low-temperature conditions; (2)The innovative rust-proof wiping layer of the present invention mainly prepares a rust-proof additive through modified paraffin. Paraffin has low fluidity under low-temperature conditions and high fluidity under high-temperature conditions. The change in the fluidity of paraffin with temperature will enable the rust-proof additive to have better stability and adhere to the surface of the weapon equipment after being wiped with a wet wipe when the weapon equipment is not working at low temperature; when the weapon equipment works and heats up, the rust-proof additive composed of paraffin has good lubricity. (3)The present invention adds a modified polyethylene glycol additive to paraffin. The polyethylene glycol molecules are inserted between the paraffin chain segments, weakening the intermolecular forces and increasing the chain segment movement ability; reducing the glass transition temperature (Tg) and enhancing the low-temperature ductility; solving the problems that paraffin becomes hard and brittle at low temperature (<0 °C), is prone to cracking or falling off, affecting the rust-proof performance of the rust-proof additive and the lubricating performance during operation; and the connected hindered phenol antioxidant can effectively improve the antioxidant performance of the rust-proof material and can also effectively improve the antioxidant performance of materials such as paraffin, thereby improving the use performance of its rust-proof additive.
