Embodiment 1

[0019] Step 1: Prepare complex emulsifier

[0020] Dissolve polyvinyl alcohol in water, add sodium dodecylsulfonate, and stir the mixture at a temperature of 40°C for 20 minutes to prepare a composite emulsifier for use;

[0021] Step 2: Prepare Antirust Wax

[0022] Melt the polyethylene wax at a temperature of 80°C to form a polyethylene wax emulsion, add 4% of the polyethylene wax emulsion to 90.6% of the acrylic emulsion, and then add 5% of the compound emulsifier to the mixture of the two, stir for 10 minutes, and add Appropriate amount of deionized water to keep the mixture as a whole in a non-coagulated state. After continuing to stir for 10 minutes, add 0.1% of leveling agent and 0.3% of wetting agent, continue stirring for 10 minutes at a temperature of 50°C, and then stand still to obtain the finished anti-corrosion agent. rust wax.

[0023] Wherein the leveling agent is: carboxymethyl cellulose wetting agent is: polyoxyethylene surfactant

Embodiment 2

[0025] Step 1: Prepare complex emulsifier

[0026] Dissolve polyvinyl alcohol in water, add sodium dodecylsulfonate, and stir the mixture at a temperature of 45°C for 25 minutes to prepare a composite emulsifier for use;

[0027] Step 2: Prepare Antirust Wax

[0028] Melt the polyethylene wax at a temperature of 85°C to form a polyethylene wax emulsion, add 5% of the polyethylene wax emulsion to 85.6% of the acrylic emulsion, and then add 9% of the compound emulsifier to the mixture of the two, stir for 15 minutes, and add Appropriate amount of deionized water to keep the mixture in a non-coagulated state. After continuing to stir for 15 minutes, add 0.1% of leveling agent and 0.3% of wetting agent. Continue stirring for 15 minutes at a temperature of 55°C. rust wax.

[0029] Wherein the leveling agent is: carboxymethyl cellulose wetting agent is: polyoxyethylene surfactant

Embodiment 3

[0031] Dissolve polyvinyl alcohol in water, add sodium dodecylsulfonate, and stir the mixture at a temperature of 45°C for 25 minutes to prepare a composite emulsifier for use;

[0032] Step 2: Prepare Antirust Wax

[0033] Melt the polyethylene wax at a temperature of 85°C to form a polyethylene wax emulsion, add 6% of the polyethylene wax emulsion to 81.6% of the acrylic emulsion, and then add 12% of the compound emulsifier to the mixture of the two, stir for 15 minutes, and add Appropriate amount of deionized water to keep the mixture in a non-coagulated state. After continuing to stir for 15 minutes, add 0.1% of leveling agent and 0.3% of wetting agent. Continue stirring for 15 minutes at a temperature of 55°C. rust wax.

[0034] Wherein the leveling agent is: carboxymethyl cellulose wetting agent is: polyoxyethylene surfactant

Abstract

The invention belongs to the technical field of anti-rust wax, and particularly relates toanti-rust waxfor an automobile chassis. The anti-rust wax comprises the following components in percentage by mass: 4-9% of polyethylene wax emulsion, 5-20% of compound emulsifier, 0.1% of flatting agent and 0.3% of wetting agent, acrylic emulsion is used as a main component of the anti-rust wax, the raw materials of the acrylic emulsion are easy to obtain and low in price, the acrylic emulsion has prominent weather resistance and has large adhesive force with the metal surface, the polyethylene wax emulsion and the acrylic emulsion are used in cooperation, the defect that a coating film of the acrylic emulsion wrinkles and falls off is overcome, polyethylene wax is a hydrophobic material, the loose form of the acrylic emulsion after film forming is effectively made up through the high hydrophobic performance of the acrylic emulsion, the acrylic emulsion and the acrylic emulsion are combined to form a dense film, so that the anti-rust wax has weather resistance and water resistance, and the anti-rust wax is good in adhesive force with a metal substrate in the aspect of anti-rust performance, not prone to falling off, long in service life and short in drying time.

Description

technical field [0001] The invention relates to the technical field of antirust wax, in particular to an antirust wax for automobile chassis and a preparation method thereof. Background technique [0002] The rust prevention of automobile chassis is the most important in daily maintenance. Rainy weather will cause the road to be muddy, and a large amount of mud and sand will splash on the chassis of the car, which is difficult to clean. It will not take long for the chassis to be corroded, oxidized, and rusted. During the anti-rust treatment, the coating should be evenly sprayed on the chassis to form a uniform anti-rust coating that retains a long-lasting layer. Anti-rust treatment of automobile chassis is divided into water-based paint anti-rust and oil-based anti-rust paint. The difference between the two is simply that the water-based paint chassis anti-rust construction is simple, convenient, and environmentally friendly, but the anti-rust ability is not strong and it ...
