Problems solved by technology

However, the currently developed water-based cleaning agents also have many shortcomings, such as: high cleaning temperature; non-biodegradable surfactants and phosphorus- and nitrogen-containing additives, waste liquid discharge pollutes the environment; the working life of the cleaning agent is not long. Long; oil stains are selective to cleaning agent components, etc.

preparation example Construction

[0014] figure 1 It is a process step diagram of the method for preparing a water-based cleaning agent for automobile parts in an embodiment of the present invention; the water-based cleaning agent includes the following components by weight percentage: 8.5-12% of composite surfactant, 6-10% of composite auxiliary agent, mixed inorganic Salt 5-8%, solubilizer diethylene glycol ether 8-10%, corrosion inhibitor benzotriazole 0.25-0.4%, organic silicon defoamer 0.05-0.1%, deionized water 59.5-72.2%, all The preparation method includes the following steps: a) preparing a composite surfactant, b) weighing and mixing raw materials, and c) adding water for mixing and stirring.

[0015] The water-based cleaning agent for auto parts mentioned in the present invention uses deionized water as a solvent and a composite surfactant as a main body, and is prepared by adding composite auxiliary agents, mixed inorganic salts, solubilizers, corrosion inhibitors and defoamers. Among them, the co...

Embodiment 1

[0017] The specific preparation method is as follows:

[0018] a) To prepare a composite surfactant, first weigh 8% of alkylphenol polyoxyethylene ether and 0.5% of sodium lauryl sulfate by weight percentage, and then mix alkylphenol polyoxyethylene ether and tendecyl sulfate at room temperature. Sodium dialkyl sulfate is put into a magnetic stirrer and mixed evenly to make a composite surfactant.

[0019] b) Weigh the raw materials and mix them. First, weigh 3% of triethanolamine, 2.4% of sodium metasilicate, 0.6% of tetrasodium edetate, 1% of sodium fluoride, and 4% of chloride by weight percentage. Sodium, 8% diethylene glycol ether, 0.25% benzotriazole, 0.05% silicone defoamer, and then put them into a magnetic stirrer and mix them evenly with the complex surfactant.

[0020] c) Add water to mix and stir, first weigh 72.2% deionized water by weight percentage, then add the deionized water into a magnetic stirrer, stir at room temperature at a stirring speed of 40r / min for...

Embodiment 2

[0022] The specific preparation method is as follows:

[0023] a) To prepare a composite surfactant, first weigh 11% of alkylphenol polyoxyethylene ether and 1% of sodium lauryl sulfate by weight percentage, and then mix alkylphenol polyoxyethylene ether and tendecyl sulfate at room temperature. Sodium dialkyl sulfate is put into a magnetic stirrer and mixed evenly to make a composite surfactant.

[0024] b) Weigh the raw materials and mix, first weigh 5% triethanolamine, 4% sodium metasilicate, 1% tetrasodium edetate, 1.6% sodium fluoride, 6.4% Sodium chloride, 10% diethylene glycol ether, 0.4% benzotriazole, 0.1% silicone defoamer, and then put them into a magnetic stirrer and mix them evenly with the composite surfactant.

[0025] c) Add water to mix and stir, first weigh 59.5% deionized water by weight percentage, then add the deionized water into the magnetic stirrer, and stir for 50min at room temperature at a stirring speed of 50r / min to form a transparent solution. L...

Abstract

The invention provides water-based cleaning agents for automobile parts and a preparation method for the water-based cleaning agents. The water-based cleaning agents include, by weight, 8.5-12% of composite surfactants, 6-10% of compound additives, 5-8% of mixed inorganic salt, 8-10% of solubilizers of diethylene glycol diethylether, 0.25-0.4% of inhibiters of benzotriazole, 0.05-0.1% of organic silicon defoamers and 59.5-72.2% of deionized water. The preparation method includes the following steps of (a) preparation of the composite surfactants, (b) weighing and mixing of raw materials and (c) water addition, mixing and stirring. The water-based cleaning agents are low in cleaning temperature, long in service life and free of toxin and pollution and have high cleaning efficiency and good anti-rust and anti-corrosion capacity, and the cleaning efficiency for automobile parts can be more than 99%.

Description

technical field [0001] The invention relates to a cleaning agent, in particular to a water-based cleaning agent for auto parts and a preparation method thereof, belonging to the technical field of mechanical processing. Background technique [0002] In the production process of auto parts, there are many parts cleaning processes. With the development of technology and the requirements of environmental protection, higher requirements are put forward for cleaning equipment and cleaning agents, mainly including the cleaning requirements in the following aspects: 1) The cleaning speed is fast, within the cleaning time set by the cleaning machine process , can remove the dirt on the surface of the parts more thoroughly; 2) non-corrosive to the parts to be cleaned; 3) the cleaning agent is low in cost, environmentally friendly, and mild in smell; 4) the cleaning process does not leave insoluble matter on the surface of the cleaning object, and does not produce new Dirt does not f...
