Embodiment 1

[0022] Embodiment 1: a kind of aluminum alloy room temperature spray cleaning agent, its constituent raw material and its weight percent are respectively:

[0023]

[0024] A preparation method of an aluminum alloy room temperature spray cleaning agent, the steps are as follows:

[0025] (1) Add the reaction amount of water into the reaction kettle, add the reaction amount of sodium metasilicate pentahydrate, sodium gluconate, and disodium edetate at 25-40°C and stir, and keep the reaction for 20 minutes.

[0026] (2) Add isomeric alcohol ether and surfactant RQ-129B (fatty alcohol polyoxyethylene ether) to the reaction kettle and stir until completely dissolved, then add solubilizer RQ-130E (dipropylene glycol methyl ether), and continue stirring for 30 Minutes until the solution is clear and transparent, keep the temperature of the reactor at 35-40°C during the reaction.

[0027] (3) After the reaction is completed, it is naturally cooled to room temperature, and after s...

Abstract

The invention relates to a normal temperature spraying detergent for aluminum alloy and a preparation method thereof. The detergent comprises the following raw materials in percentage by weight: 1 to 5 percent of ethylene diamine tetraacetic acid, 0.5 to 1.5 percent of sodium metasilicate pentahydrate, 5 to 8 percent of sodium gluconate, 5 to 10 percent of heterogeneous alcohol ether, 2 to 7 percent of solubilizing agent, 3 to 8 percent of surfactant, and the balance of water. The detergent can be used at normal temperature, and does not need heating so as to save the energy; the detergent does not corrode the treated aluminum alloy parts, does not leave white spots on the surfaces of the parts, and can increase the brightness of the parts; and the detergent has long service life and low using concentration, is safe and environment-friendly, saves the working time, and improves the working efficiency.

Description

technical field [0001] The invention relates to the fields of chemical cleaning and antirust, in particular to an aluminum alloy room temperature spray cleaning agent and a preparation method thereof. Background technique [0002] In the cleaning industry, especially for the cleaning of aluminum alloy workpieces, the parts will be corroded soon after cleaning, especially if the commonly used water-based aluminum alloy cleaning agent is used, the cleaned workpieces cannot meet the cleaning quality standards, and the oil stains cannot be washed away. , that is, the workpiece is corroded; and most of the workpieces begin to change color after being placed for a period of time after cleaning, which seriously affects the cleaning quality. [0003] By searching, there are two following patent documents related to this patent application, which are respectively: 1. A cleaning agent for aluminum and aluminum alloys (CN101012411), which consists of alkylphenol polyoxyethylene ether (...
