Embodiment 1

[0012] An automobile chassis antirust wax-water emulsion is characterized in that the preparation steps are as follows:

[0013] ① Put 120 kg of 80# microcrystalline wax in a 2000L stainless steel reaction kettle (outer cover insulation layer), heat to 80°C, stir at 80 rpm for 10 minutes until the paraffin is completely melted.

[0014] ② Add 60 kg of petroleum resin while stirring, stop heating when the temperature rises to 100°C, and continue stirring for 10 minutes until the petroleum resin is completely dissolved.

[0015] ③ Add 40 kg of higher fatty acid, stir to dissolve completely, and continue to stir until the temperature drops to 90°C;

[0016] ④Take 16 kg of triethanolamine, dissolve it in 85°C hot water, add it into the reaction kettle under stirring conditions, and continue to add 85°C hot water at the same time, and continue stirring until the temperature drops below 50°C.

[0017] ⑤ Take 0.5kg of metal corrosion inhibitor, dissolve it in 5 kg of wa...

Abstract

The invention discloses a rustproof wax water emulsion for an automobile chassis. The rustproof wax water emulsion is prepared by using an emulsification technology through the specific steps that microcrystalline wax and petroleum resins in a certain proportion are heated to be 100-120 DEG C for melting; a composite emulsifying agent is added and fully stirred; the temperature is reduced to be 90 DEG C; hot water with the temperature of 85-95 DEG C is continuously added and continuously stirred for 30 minutes at constant temperature so as to prepare composite paraffin emulsion; the composite paraffin emulsion is cooled to be below 50 DEG C; 0.05-0.15 percent of corrosion inhibitor solutions are added and continuously stirred for 10 minutes. Volatile toxic organic solvents are replaced by water, so that the convenience of application is improved, the working environment is improved, and the health of operators is guaranteed; under the premise of guaranteeing the rustproof protection effect, the unit cost is reduced by 40 percent. The rustproof wax water emulsion is milk-white even semitransparent liquid, fine in granularity, moderate in viscosity, good in film-forming property, fast in drying, high in adhesion, and high in hydrothermal resistant property and high in rustproof protection performance.

Description

technical field [0001] The invention relates to an antirust protection liquid for automobile body and chassis, in particular to an antirust wax-water emulsion for automobile chassis. Background technique [0002] At present, the existing anti-rust wax for automobile chassis (CN02115915.7, CN201110034909.5) is solvent-based and contains a relatively large proportion (40%~90%) of volatile organic solvents. During the construction process, toxic gases will be released, which will endanger the health of operators. healthy. And the cost is higher. Contents of the invention [0003] The object of the present invention is to provide a kind of automobile chassis rust-proof wax-water emulsion in order to solve the above problems. [0004] The technical solution of the present invention to achieve the above-mentioned purpose is that an aqueous emulsion of anti-rust wax for automobile chassis adopts emulsification technology to prepare an aqueous emulsion of anti-rust wax, heat a f...
