Embodiment Construction

[0022] Take 5-10g beeswax, 5-10g oxidized paraffin, 5-10g water-based alkyd resin, 5-10g petroleum resin, put them into a grinder and grind for 30-40min to obtain compound paraffin, take 8-16g phytic acid, 2 Put ~4g of tannic acid into a mixing tank, stir at 300~400rmin for 20~30min to obtain a composite antirust agent, take 2~3g of nanographene, add it to 200~300g of absolute ethanol, and disperse it with 300W ultrasonic wave for 15 ~20min, then add 6~9g oleic acid, heat to 60~80℃, stir at 300~400r / min for 2~3h, cool to room temperature and filter the filter residue, wash the filter residue 2~3 times with absolute ethanol Transfer the filter residue into a drying oven and dry at 120-150°C for 2-3 hours to obtain modified nano-graphene. Put 20-40g of composite paraffin into the reaction kettle, heat it to 70-120°C and heat it at 200-300r / min Stir for 20-30 minutes, then add 10-20g composite anti-rust agent, 1-2g wetting and dispersing agent, and 2-4g emulsifier in order to dis...

Abstract

The invention relates to stone-crash-resistant automobile corrosion-resistant wax and a preparation method thereof, and belongs to the technical field of metal corrosion prevention. The characteristicthat environment-friendly phytic acid compounds inositol hexaphosphoric acid and tannic acid are liable to be self-assembled on the surface of metal to form a film is utilized; when the environment-friendly phytic acid compounds inositol hexaphosphoric acid and tannic acid are contacted with the surface of the metal, the two anti-rust groups are chelated with the surface of the metal to generateone layer of compact passivation film, and composite paraffin is met and guided to gradually form a protective wax film on the surface of plate material; on the other hand, the two anti-rust groups have optimal compatibility with metal polymers with excellent corrosion resistance such as titanium and aluminum in the metal, the two anti-rust group and a film-forming substance jointly form a corrosion-resistant layer with high compactness on the surface of the metal, and the corrosion-resistant layer has extremely high barrier property on erosion and corrosion mediums such as water, oxygen and ions. The corrosion-resistant wax prepared by the method has extremely high barrier property and high stone crash resistance, is applied to the surface and the hole gap of the material by a spray-coating mode, and has high long-time corrosion resistance.

Description

technical field [0001] The invention relates to an anti-stone-cut automobile anti-corrosion wax and a preparation method thereof, belonging to the technical field of metal anti-corrosion. Background technique [0002] In recent years, my country's automobile industry has developed rapidly, and the number of automobiles has ranked first in the world. In such a big environment, in order to ensure the quality of automobiles, vehicle anticorrosion has become an important issue that cannot be ignored. In order to protect the interests of consumers and reduce the pressure on environmental protection, some developed countries and regions have formulated corresponding automobile corrosion regulations, and set requirements for the antirust level of vehicles sold in their markets. For example, the United Kingdom, Italy, Russia, Australia, the Baltic Sea and the Nordic regions require the surface of the car body to be at least 3 years or 1.0×10 5 km without corrosion, and passenger c...
