Technical Field

The invention relates to the technical field of cleaning agents, in particular to an environment-friendly industrial cleaning agent and a preparation method thereof.

Background

In industrial production and service activities, the industrial cleaning agent can remove dirt on the surfaces of industrial products (and parts thereof), production equipment and auxiliary facilities to achieve certain cleanliness, plays an important role in improving the product quality, safely operating the equipment, saving energy, reducing emission and the like, and becomes an indispensable special chemical product in industrial production and operation activities.

The working principle of the industrial cleaning agent is to remove dirt (including grease, paint, ink, colloid, carbon deposit, dust and the like) on the surfaces of devices, equipment, facilities and products by using the principles of dissolution, complexation, emulsification, wetting, penetration, dispersion, solubilization, stripping and the like of chemical substances.

Although the traditional industrial cleaning agent mostly uses chlorine-containing solvents (dichloromethane and trichloromethane), the chlorine-containing solvents are very effective as cleaning enhancers, but the chlorine-containing solvents have great harm to human bodies and can damage nerves and organs of the human bodies, the solvents are not environment-friendly, and the VOCs (volatile organic chemicals) using the solvents are easy to exceed the standard. According to comprehensive research on cleaning agent production enterprises, a certain amount of chlorine-containing solvent is added to partially clean paint and heavy oil dirt to meet the cleaning requirement, and after industrial research and comprehensive evaluation, a 20% limit value is given, and most cleaning agents containing the substances can be basically eliminated.

Therefore, a cleaning agent which has a cleaning power comparable to that of the conventional chlorine-containing cleaning agent and is environmentally friendly is needed.

The second aspect of the application provides a preparation method of an environment-friendly industrial cleaning agent.

The application provides an environment-friendly industrial cleaning agent which comprises the following components in percentage by weight:

30 to 45 percent of trimethylbenzene

8-15% of No. 120 solvent oil

20-35% of acetone

25-30% of propellant.

In one embodiment, the propellant consists of liquefied petroleum gas and carbon dioxide.

In one embodiment, the weight ratio of the liquefied petroleum gas to the carbon dioxide is 20 to 30: 1 to 5.

The application has the beneficial effects that:

the environment-friendly industrial cleaning agent is prepared from trimethylbenzene, 120# solvent oil, acetone and a propellant in proportion.

(1) The trimethylbenzene has the characteristics of strong dissolving power, low toxicity, small smell, high boiling point, slow volatilization, no water or olefin and no chlorine, and can play a role in high dissolving power in the later stage of evaporation, so that the cleaning performance is good, in addition, the acetone has a cleaning function and can improve the volatilization rate, the No. 120 solvent oil is mainly used for dissolving stubborn dirt, and the propellant can increase the pressure injection rate and greatly improve the cleaning power.

Therefore, the mutual matching of the trimethylbenzene, the No. 120 solvent oil, the acetone and the propellant can ensure that the cleaning agent has high dirt cleaning speed, complete dirt dissolving, strong reaction, dispersion or dissolution cleaning capability on the dirt, and can completely remove the dirt in a limited construction period. When cleaning, the dirt can be thoroughly cleaned without depending on temperature control or intensive conditions such as hard scrubbing and the like.

(2) The components are nontoxic or low-toxic, so that the cleaning agent is nontoxic or low-toxic to organisms and the environment, and the generated waste gas, waste liquid and waste residues can be treated to meet the requirements of relevant national regulations.

(3) Although the cleaning agent is volatile, the cleaning agent comprises the components of trimethylbenzene, acetone and No. 120 solvent naphtha, the VOC value is low, the trimethylbenzene has a wider distillation range and a higher octane value, can assist in dissolving colloid, and has a cleaning effect.

(4) Trimethylbenzene and other components in the components of the cleaning agent cannot react with metal, so that the cleaning agent does not corrode a tin can and a valve and is not easy to leak.

(5) Because the trimethylbenzene can exert high dissolving power in the post-cleaning stage, insoluble substances or new stains cannot be left on the surface of a cleaning object in the cleaning process, a new harmful covering layer cannot be formed, and the quality of a cleaning product is not influenced.

The cleaning agent does not contain chlorine but has a cleaning effect not lower than that of a chlorine-containing cleaning agent through the proportion of trimethylbenzene, 120# solvent oil, acetone and a propellant, is low in toxicity, environment-friendly, strong in cleaning power and low in VOC value, and is suitable for various industrial environments.

The second aspect of the invention is realized by the following technical scheme:

provides a preparation method of the environment-friendly industrial cleaning agent, which comprises the following steps,

uniformly mixing trimethylbenzene, 120# solvent oil and acetone according to the formula ratio to prepare feed liquid;

filling the obtained feed liquid into a tank body, sealing the tank body, and filling propellant to obtain the target product.

In one embodiment, the method further comprises the step of performing water leakage detection on the target product.

In one embodiment, the water leak detection is a constant temperature water bath leak detection.

The preparation method of the environment-friendly industrial cleaning agent has the beneficial effects that:

the preparation method of the invention can prepare the required industrial cleaning agent only by simple mixing, and has the advantages of easy operation and suitability for large-scale production and application.
