Embodiment 1

[0020] A spray cleaning agent for die-casting aluminum shells applied under ultra-high pressure, consisting of the following components in weight percentage: 1% sodium citrate, 4% sodium gluconate, 3% 3-methoxy-3-methyl - Butanol, 1.5% sodium metasilicate pentahydrate, 1% ethanol, 4% PEG400, 1% sodium polyacrylate, 5% SimulsolAS48, 6% PE6400, 1% Marlox MO 124, 0.1% AFE-7610 and 72.4% water .

[0021] The die-casting aluminum housing spray cleaning agent of Example 1 is prepared by the following preparation process:

[0022] Step 1, add the formula amount of water into the reaction kettle, add the formula amount of sodium citrate, sodium gluconate and sodium metasilicate pentahydrate into the reaction kettle at room temperature, and stir until the materials are completely dissolved;

[0023] Step 2, add sodium polyacrylate, 3-methoxy-3-methyl-butanol, ethanol, PEG400, alkyl glycoside Simulsol AS48, PE6400 and fatty alcohol EO-PO in the reaction kettle of step 1 Block copolyme...

Embodiment 2

[0026] A spray cleaning agent for die-casting aluminum shells applied under ultra-high pressure, consisting of the following components in weight percentage: 2% sodium citrate, 2% sodium gluconate, 5% 3-methoxy-3-methyl - Butanol, 3% sodium silicate, 2% ethanol, 5% PEG400, 0.5% sodium polyacrylate, 5% Simulsol AS48, 8% PE6400, 1.5% Marlox MO 124, 0.2% AFE-7610 and 65.8% water.

[0027] The die-casting aluminum housing spray cleaning agent of Example 2 is prepared by the following preparation process:

[0028] Step 1, add the formula amount of water into the reaction kettle, add the formula amount of sodium citrate, sodium gluconate and sodium silicate into the reaction kettle at room temperature, and stir until the materials are completely dissolved;

[0029] Step 2, add the formula amount of sodium polyacrylate, 3-methoxy-3-methyl-butanol, ethanol, PEG400, alkyl glycoside AS48, PE6400 and fatty alcohol EO-PO block into the reaction kettle of step 1 Copolymer, keep stirring f...

Embodiment 3

[0032] Take a certain amount of the die-casting aluminum shell spray cleaning agent of Example 1 and mix it with water to obtain a standby cleaning solution with a mass percentage concentration of 3%; place the standby cleaning solution in the tank of the cleaning machine, and adjust the temperature Heat to 20-40°C, fix the die-casting aluminum gearbox housing on the rack of the cleaning machine, adjust the spray pressure to 15MPa, spray and clean for 3 minutes, and dry with cold wind after cleaning.

[0033] The spray cleaning agent for the die-casting aluminum shell of the present invention quickly eliminates the generated foam during the ultra-high pressure spray cleaning process, and no overflow phenomenon occurs; the surface of the workpiece after cleaning has no oil stains and no white residues, and the surface of the die-casting aluminum shell does not occur Corrosion and discoloration, the machined surface is bright; the filtration accuracy of the cleanliness test is 10...

Abstract

The invention discloses a die-casting aluminum housing spraying cleaning agent applied to ultrahigh pressure. The die-casting aluminum housing spraying cleaning agent applied to ultrahigh pressure comprises the following components in percentage by weight: 1-2% of sodium citrate, 2-4% of sodium gluconate, 3-5% of 3-methoxy-3-methyl-butanol, 1.5-3% of aluminum corrosion inhibitor, 1-2% of ethyl alcohol, 3-5% of polyethylene glycol, 0.5-1% of sodium polyacrylate, 3-5% of alkyl glycoside, 5-8% of EO-PO segmented copolymer, 1-2% of fatty alcohol EO-PO segmented copolymer, 0.1-0.2% of antifoaming agent, and 65-75% of water. The cleaning agent can remain a low-bubble and even non-bubble state while removing burr at the spraying pressure of 2-15MPa under the temperature of 20 to 40 DEG C, and the residue level is low after cleaning.

Description

technical field [0001] The invention relates to a metal spray cleaning agent, in particular to a spray cleaning agent applied to a die-casting aluminum shell under ultra-high pressure. Background technique [0002] As an important core component of the automobile powertrain, the gearbox has very high processing technology content, equipment level and quality requirements. Its excellent product performance is a key factor that reflects the core competitive advantage of the complete vehicle enterprise. The core parts of the gearbox mainly include shafts, gears and housings. The parts must be strictly cleaned before assembly to remove metal shavings, dust, cutting fluid, grease and other pollutants on the surface. Among them, the shell is usually made of die-cast aluminum. Due to the active chemical properties of aluminum, the requirements for cleaning effect are more complicated than those of ferrous metals. Not only the cleanliness after cleaning is required to meet the stand...
