preparation example Construction

[0038] Such as figure 1 As shown, the preparation method of the coating material for light alloy pulping comprises the following steps:

[0039] 1S prepares modified simethicone, anionic and nonionic surfactant compounding agents, co-emulsifiers, water-soluble polymers, regulators and defoamers.

[0040] 2S Add the anionic and nonionic surfactant compounding agent into the water-soluble polymer and stir for 10-20 minutes.

[0041] 3S Add modified simethicone, auxiliary emulsifier, and defoamer to the solution in step 2S and stir together under constant temperature water bath conditions. The stirring time is set at 10-30 minutes, and the water bath temperature is 45-60 degrees Celsius.

[0042] 4S: Add the regulator to the solution obtained in step 3S, and stir at 20-25 degrees Celsius until the solution becomes a uniform and transparent emulsion, stop stirring, and set the stirring time to 60-80 minutes.

[0043] 5S measures the pH value of the emulsion obtained in step 4S, ...

Embodiment 1

[0046] A coating material for light alloy pulping contains the following components, and the content of each component indicates

[0047] as follows:

[0048]

[0049] The coating material used for light alloy pulping in Example 1 has excellent high-temperature wettability, and the coated stirring rod can quickly form a layer of high-temperature resistant, erosion-resistant, micron-scale thick at a temperature as high as 450 degrees Celsius. Uniform film.

Embodiment 2

[0051] A coating material for light alloy pulping contains the following components, and the content of each component is expressed as follows:

[0052]

[0053] The coating material used for light alloy pulping in Example 2 has excellent corrosion resistance and increases the number of uses of the stirring rod. The traditional stirring rod uses hot-work steel H13 material to produce 3000 molds, that is, the surface corrosion is scrapped, and the coating of Embodiment 2 is used. After the material is coated with the stirring rod, the service life is as high as 11000 times.

Abstract

A coated material for light alloy pulping, comprising the following components in parts by weight: 7-10 parts of modified dimethyl silicone oil, 8-15 parts of anionic and nonionic surface active complexing agent, 0.5-1 part of auxiliary emulsifier, 0.2-0.4 part of water-soluble polymer, 1.5-3 parts of conditioning agent, and 1-2 parts of defoamer. The preparation method for the coated material comprises: 1S, preparing the material, 2S, adding the anionic and nonionic surface active complexing agent to the water-soluble polymer for stirring, 3S, adding the modified dimethyl silicone oil, the auxiliary emulsifier, and the defoamer to the solution in 2S for stirring 10-30 minutes, 4S, adding the conditioning agent to the solution obtained in step 3S for stirring 60-80 minutes which are set, and 5S, measuring the pH of the emulsion to obtain the coated material for light alloy pulping.

Description

technical field [0001] The patent of the invention relates to the field of casting, in particular to a high-performance coating material for a light alloy semi-solid pulping device and a preparation method thereof. Background technique [0002] The traditional method uses mechanical stirring to prepare semi-solid light alloy slurry. During the slurry preparation process, the manipulator scoops up the light alloy liquid to the preset position, and the stirring rod stirs the light alloy liquid in the spoon according to the set parameters. After the stirring is completed, the manipulator spoon sends the slurry to the pressure chamber for pouring and die-casting. At the same time, the stirring rod passes through the waste treatment device to remove the aluminum slag (alumina) adhered to the surface, and the coating agent storage device returns to the original position after coating the coating agent. One production beat. Traditional coating agents are not resistant to high temp...
