Description
Technical Field
The invention belongs to the field of cleaning, and relates to a cleaning liquid and application thereof.
Background
The importance of a brake system as an important component of a motor vehicle is self-evident in relation to driving safety. In the daily use process of the brake system, brake dust powder, oil dirt, dust and the like can be continuously adhered, the formation and accumulation of the dirt can gradually influence the brake performance, abnormal sound of the brake can be caused if the brake is light, brake failure can be caused if the brake is heavy, and driving safety is seriously threatened. Therefore, regular cleaning maintenance of the brake system is indispensable. In the steam repair link, the brake system cleaning agent is the most basic in the cleaning and maintenance of the brake system, and is also the most important product.
Conventional brake system cleaners are based on strong solvents such as aromatic hydrocarbons, halogenated hydrocarbons, ketones, esters, and the like. These solvents are strong in dissolving power and can quickly dissolve and remove dirt adhered to the wading system. However, these solvents are highly volatile, and readily volatilize to form volatile organic gases (i.e., VOCs) at normal temperature, which are not environmentally friendly, and halogenated hydrocarbons, aromatic hydrocarbons, etc. are limited in use due to their excessive toxicity to the environment and the human body. At the same time, these solvents tend to emit unpleasant, irritating odors that are more unacceptable especially in small and poorly ventilated automotive repair workshops, not only affecting the user experience, but also adversely affecting the health of the body by extensive or prolonged exposure. In addition, these solvents are too corrosive and can be corrosive to some plastics or seals, easily causing irreversible damage, resulting in loss of properties and even affecting braking performance.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, provides a cleaning solution and application thereof, and aims to ensure that the cleaning solution has good decontamination effect on a brake system, meets the requirement of GB38508-2020 'limit value of the volatile organic Compound content of the cleaning solution', and even can achieve the effects of soft and coordinated smell and low corrosiveness by adjusting the dosage of the cleaning solution components.
To achieve the above object, in a first aspect, the present invention provides a cleaning solution, comprising the following components in weight content:
wherein the weight ratio of hexane to alcohol is less than or equal to 3.
The cleaning liquid takes hexane as a main solvent, does not corrode chloroprene rubber, has stronger detergency and lower toxicity, can replace various dangerous organic solvents such as acetone, benzene, toluene, xylene, methylene dichloride, trichloroethylene and the like, has obvious cleaning effect, has low odor, quick volatilization and less residue, and is an ideal cleaning agent raw material.
The cleaning liquid takes alcohols as auxiliary solvents, has moderate volatilization rate, can adjust the volatilization rate and improves the cleaning effect. When the weight ratio of hexane to alcohol is more than 3, the volatilization speed of the cleaning liquid is higher, and the decontamination effect is poorer, so that the weight ratio of hexane to alcohol is less than or equal to 3 to avoid too high volatilization speed, and good decontamination effect is obtained.
The environment-friendly solvent BT154 (BT 154 for short) is a polyol ether ester solvent containing polyfunctional groups of BRENTAG company, has the advantages of no toxicity, biodegradability, easy recycling, no corrosion, no cancerogenesis, good solubility and the like, takes plant bodies as raw materials, belongs to biological solvents, solves the problems of health and environmental pollution caused by volatilization of traditional solvents, is environment-friendly, has good dissolving capacity for resin with small polarity, can dissolve most of natural resins such as nitrocellulose, cellulose acetate, alkyd resin, kauri, manila resin, rosin, shellac, vinyl resin and the like and part of synthetic resins, has natural fragrance, has a certain odor covering effect, effectively improves the working environment of strong pungent odor generated by the traditional solvents, and has a better covering effect on the odor of alcohol in the cleaning liquid.
D30 solvent naphtha is refined low-flash kerosene, has extremely low total nitrogen content and sulfur content, no pungent odor, good chemical stability and strong penetrability, can reduce the volatilization rate of n-hexane and cyclohexane, and helps the n-hexane and cyclohexane to better permeate into dirt, thereby improving the cleaning effect; the benzyl alcohol has better permeability and fat solubility and special aromatic smell, so that the permeability of the cleaning liquid can be improved, and the smell of alkane and alcohol can be effectively neutralized, so that the smell of the product is more coordinated, and the user experience is improved. Under the combined action of D30 solvent oil and benzyl alcohol, the cleaning liquid not only can realize better decontamination effect, but also can avoid too uncoordinated smell.
The corrosion inhibitor can prevent the coating material and the construction substrate from corroding and rusting.
The cleaning liquid takes hexane and alcohol as main decontamination raw materials, has good decontamination effect, no pungent smell and VOC content less than 900g/L, meets the requirements of national mandatory standards GB38508-2020 on the limit value of the content of volatile organic compounds of cleaning agents, and solves the problem that the traditional cleaning agent for the brake system is not friendly to the environment. Meanwhile, the effects of soft and coordinated smell and low corrosiveness can be achieved by adjusting the dosage of each component.
Preferably, the weight ratio of the hexane to the alcohol is not less than 2.7. When the weight ratio of hexane to alcohol is less than 2.7, the volatilization speed of the cleaning liquid is slow and the construction efficiency is low, so that the weight ratio of hexane to alcohol is preferably not less than 2.7.
Preferably, the hexane includes n-hexane and cyclohexane. By using a combination of n-hexane and cyclohexane, too fast or too slow volatilization of the cleaning solution is avoided.
Preferably, the weight ratio of the n-hexane to the cyclohexane is 1.3:1-2.5:1. When the weight ratio of the n-hexane to the cyclohexane is 1.3:1-2.5:1, the volatilization speed of the cleaning liquid is moderate, and the decontamination effect is good.
Preferably, the weight ratio of the n-hexane to the cyclohexane is 2:1. When the weight ratio of n-hexane to cyclohexane is 2:1, n-hexane and cyclohexane have a synergistic effect on decontamination.
Preferably, the alcohol comprises anhydrous ethanol and isopropanol, wherein the weight ratio of the anhydrous ethanol to the isopropanol is 0.9:1-1.1:1. The inventors found that when the weight ratio of the anhydrous ethanol to the isopropyl alcohol is too high or too low, the detergency effect is poor, and when the weight ratio is in the range of 0.9:1 to 1.1:1, the detergency effect is good, particularly when the weight ratio is 1:1.
Preferably, the alcohol is present in an amount of less than 27% by weight. When the weight content of the alcohol is 27% or more, corrosion is generated to the chloroprene rubber, and therefore, it is preferable that the weight content of the alcohol is less than 27% to avoid corrosion of the chloroprene rubber.
Preferably, the weight content of the environment-friendly solvent BT154 is 2-3%. When the weight content of the environment-friendly solvent BT154 exceeds 3%, the chloroprene rubber is easy to corrode; and when the weight content of the environment-friendly solvent BT154 is controlled within the range of 2-3%, the environment-friendly solvent BT154 is not corroded to chloroprene rubber, and has good decontamination effect.
Preferably, the weight content of the D30 solvent oil is 1-2%. The larger the D30 solvent oil is, the better the penetrating effect is, which is favorable for improving the detergency, but when the dosage is too large, the detergency of the cleaning liquid is reduced as a whole due to the fact that the self detergency is not strong, and the weight content of the D30 solvent oil is preferably 1-2% in consideration of the cost.
Preferably, the benzyl alcohol is 1.3-2.5% by weight. The larger the benzyl alcohol is, the better the penetrating effect is, which is favorable for improving the detergency, but when the benzyl alcohol is excessively used, the aromatic flavor of the benzyl alcohol is excessively prominent, so that the overall smell of the cleaning liquid is inconsistent. Therefore, the benzyl alcohol content is preferably 1.3 to 2.5% by weight.
Preferably, the cleaning liquid comprises the following components in parts by weight: 45.3 to 46.7 percent of normal hexane, 22.7 to 23.3 percent of cyclohexane, 12 to 13 percent of absolute ethyl alcohol, 12 to 13 percent of isopropanol, 2 to 3 percent of environment-friendly solvent BT154, 2 percent to 2.5 percent of D30 solvent oil, 1.5 to 2.5 percent of benzyl alcohol and 0.5 percent of corrosion inhibitor. The cleaning solution has the decontamination effect of over 99 percent, moderate volatilization speed, no corrosion to chloroprene rubber and soft smell.
Preferably, the cleaning liquid comprises the following components in parts by weight: 46% of normal hexane, 23% of cyclohexane, 12% of absolute ethyl alcohol, 12% of isopropanol, 3% of environment-friendly solvent BT154, 2% of D30 solvent oil, 1.5% of benzyl alcohol and 0.5% of corrosion inhibitor. The capability of removing greasy dirt of the cleaning liquid with the specific composition reaches 99.7%, and the cleaning liquid has no corrosion to chloroprene rubber and soft smell.
Preferably, the corrosion inhibitor is polyglycerol oleic acid.
In a second aspect, the present invention provides an aerosol-type cleaning agent comprising the cleaning liquid, a propellant and a compressed gas. The cleaning liquid, the propellant and the compressed gas are combined to prepare the aerosol cleaning agent.
Preferably, the propellant is LPG (liquefied petroleum gas). LPG has excellent miscibility, can be mixed with an organic solvent in the cleaning liquid to form homogeneous phase, and can achieve the effect of having a better spraying state without shaking the tank body when in use, thereby simplifying the use flow.
Preferably, the weight of the LPG is 30% of the weight of the cleaning agent. When the weight of the LPG is 30% of the weight of the cleaning agent, the atomization effect is good, no residual liquid is left, and the pressure is within the deformation pressure of the aerosol can.
The compressed gas is used as a spraying power auxiliary agent, so that the internal pressure of the product can be effectively increased, the scouring effect is enhanced, and the decontamination capability is improved. Preferably, the pressure of the cleaning agent is 0.70-0.75MPa. The compressed gas is filled too little, and the scouring force is insufficient; the space in the tank can be reduced due to excessive compressed gas filling, and the stock solution loading is reduced. Preferably, the pressure of the cleaning agent is brought to a pressure in the range of 0.70-0.75MPa by the compressed gas.
Preferably, the compressed gas is compressed carbon dioxide. The compressed carbon dioxide has the characteristics of low price and high pressure, and can effectively reduce the use of the propellant and help control the cost.
In a third aspect, the present invention provides the use of said cleaning fluid in cleaning a braking system.
Compared with the prior art, the invention has the beneficial effects that: the cleaning solution disclosed by the invention takes hexane and alcohol as main decontamination solvents, the weight ratio of hexane to alcohol is less than or equal to 3, the decontamination effect is good, no pungent smell exists, the VOC content is less than 900g/L, the requirements of national mandatory standards GB38508-2020 on the limit value of the volatile organic compound content of cleaning agents are met, the problem that the traditional braking system cleaning agent is not friendly to the environment is solved, and the effects of soft and harmonious smell and low corrosiveness can be realized by controlling the consumption of each component of the traditional braking system cleaning agent.

(1) Detergency: evaluation of cleaning power of cleaning agent by artificial greasy dirt
Referring to the oil stain formula in QB/T2117 general Water-based Metal cleaner, and combining with the actual oil stain condition of a brake system, the artificial oil stain is prepared, and comprises the following components: 8wt% of barium petroleum sulfonate, 2wt% of lanolin, 20wt% of industrial vaseline, 15wt% of liquid paraffin, 25wt% of 20# mechanical oil, 15wt% of 46# mechanical oil, 5wt% of stearic acid and 10wt% of carbon black; the preparation method of the artificial oil stain comprises the following steps: heating barium petroleum sulfonate, lanolin, industrial vaseline, liquid paraffin, 20# mechanical oil and 46# mechanical oil to 85 ℃ according to the formula, adding stearic acid while stirring, stirring until the mixture is completely dissolved, stopping heating, adding carbon black, uniformly dispersing, standing at a constant temperature of 240+/-2 ℃ for 24 hours, taking out, and cooling to room temperature to obtain the artificial greasy dirt. The obtained artificial oil stain is stored in a refrigerator or dryer at 5-10 ℃ for standby.
The method comprises the steps of adopting a metal test piece with the same specification as QB/T2117 general water-based metal cleaning agent, coating the test piece according to requirements, then placing the metal test piece coated with the artificial oil stain in an oven at 150+/-2 ℃ for drying for 2 hours, recording the weight of the metal test piece before the oil stain is coated and the weight of the metal test piece after the oil stain is dried, clamping the metal test piece on a swing frame of a swing washer, enabling the surface of the test piece to be perpendicular to the swing direction, and placing a tray under the test piece to collect the sewage. The aerosol type cleaning agent was placed 15cm from the test piece, the nozzle was pressed down and continuously sprayed for 15 seconds, and the detergency was calculated according to the method of QB/T2117.
(2) Volatilization speed
And (3) spraying an equivalent amount of product to the 5 x 5cm iron test piece (pressing the valve once according to the aerosol type cleaning agent), recording the time required by the complete volatilization of the cleaning liquid on the iron test piece, and dividing the time into three steps of fast, moderate and slow according to the volatilization time, wherein the volatilization time of the fast speed is less than or equal to 10s, the volatilization time of the moderate speed is more than 10s and less than or equal to 20s, and the volatilization time of the slow speed is more than 20s. Too fast volatilization and short contact time with the greasy dirt, and influence the decontamination effect; too slow volatilization, difficult drying, influence the efficiency of construction.
(3) Corrosiveness of
The method comprises the steps of taking a chloroprene rubber ring commonly used for a sealing piece of a brake system as a testing material, soaking the chloroprene rubber ring in a cleaning liquid, sealing, placing in a 50 ℃ oven for 24 hours, taking out the swelling ratio of the chloroprene rubber ring to be measured in real time, and taking an absolute value. If the absolute value of the swelling ratio is more than or equal to 1%, judging that the corrosion exists; if the absolute value of the swelling ratio is less than 1, it is determined that there is no corrosion.
(4) Smell of
Sensory judgment, the smell is classified into soft and strong, and the smell is suitable for softness.
The test results of each aerosol type cleaning agent are shown in table 3. Meanwhile, the VOC content of the cleaning agent in the test group 1-19 is less than 900g/L by adopting a chromatographic analysis method, benzene, toluene, ethylbenzene, xylene, methylene dichloride, trichloromethane, trichloroethylene, tetrachloroethylene, formaldehyde and the like are not detected, and the cleaning agent meets the requirements of national mandatory standards GB38508-2020 for limiting the content of volatile organic compounds of cleaning agents.
TABLE 3 Table 3
As shown in Table 3, when the weight ratio of hexane to alcohol is more than 3, the volatilization speed of the cleaning liquid is high and the decontamination effect is poor; when the weight ratio of hexane to alcohol is less than 2.7, the volatilization speed of the cleaning liquid is slower, and the construction efficiency is lower. When hexane is selected from n-hexane or cyclohexane only, the volatilization speed of the cleaning solution is too high or too low, and when n-hexane and cyclohexane are combined, moderate volatilization speed can be obtained, so that the cleaning solution has good decontamination effect and higher construction efficiency, and when the weight ratio of n-hexane to cyclohexane is 2:1, the two give full play to the synergistic effect, so that the cleaning solution has the best decontamination effect. When the weight ratio of the absolute ethyl alcohol to the isopropyl alcohol is too high or too low, the decontamination effect of the cleaning liquid is poor, and when the weight ratio of the absolute ethyl alcohol to the isopropyl alcohol is in the range of 0.9-1.1, the absolute ethyl alcohol and the isopropyl alcohol show obvious synergistic effect, so that the cleaning liquid obtains better cleaning effect. When the total alcohol content in the cleaning liquid is less than 27%, corrosion of the neoprene can be avoided. The higher the content of the environmentally friendly solvent BT154, the better the decontamination effect, but when the content exceeds 3wt%, corrosion to the chloroprene rubber occurs. D30 solvent oil and benzyl alcohol have an effect of promoting permeation, but only either one of them is used, which results in too strong an uncoordinated smell (comparative examples 4 to 5 are more strongly uncoordinated than the smell of each example); the higher the D30 solvent oil content is, the better the penetrating effect is, which is favorable for improving the detergency, but when the dosage is too large, the overall detergency of the cleaning liquid is reduced due to the fact that the self detergency is not strong.
In addition, the VOC content of the cleaning solution in each embodiment is less than 900g/L, and meets the requirements of the national mandatory standards GB38508-2020 on the limit value of the volatile organic Compound content of the cleaning agent.
Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solution of the present invention may be modified or substituted equally without departing from the spirit and scope of the technical solution of the present invention.
