Description
CA 021016~1 1998-04-08 -SURFACE CLEANING AGENT
The present invention relates to the field of detergents, and more particularly, to surface cleaning agents.
The above agent can be widely used at machine-tool, metallurgical, aircraft, radio engineering, transport, repair and a number of other enterprises for cleaning metal, glass, plastics, paint-and-varnish and ceramic surfaces of carbon black and in-service fouling of petroleum character, as well as of corrosion-preventive lubricants, lubricant-coolants, metal and plastic chips.
Such an agent can also be used for cleaning of parts between operations, cleaning of various surfaces of production areas and equipment during repair and preventive maintenance, cleaning of electric machines, various-purpose electrical equipment of different overall dimensions, as well as for washing overalls.
A number of requirements are imposed upon such agents for cleaning surfaces. Along will a high detergent ability, they must be fire- and explosion-proof, efficient within a broad range of temperatures, non-toxic, must not exert negative effect on the surface (cause corrosion, CA 021016~1 1998-04-08 leave deposits, including those current-conducting), and be convenient in mechanical and automatic cleaning. It is also desirable that the agent be reusable and that reclamation and utilization of it be possible.
Known in the art are various detergents. As a rule, they contain surfactants and various additives, promoting enhanced efficiency of detergent effect (wettability, emulsification, solubilization, foam killing and passivation of surface).
Thus, for example, known in the art is a detergent for cleaning hard surfaces of fouling (SU, A, 290066). This detergent consists of a surfactant and an alkali additive.
As a surfactant, use is made of alkyl benzene sulfonates (C12-Cl8), and as an alkali additive - 25-50% by mass of soda ash, 30-25% by mass of sodium tripolyphosphate and 10%
by mass of sodium silicates. Such a detergent efficiently washes off surfaces to be cleaned; however, owing to a high content of soda ash, it can exert aggressive effect on the cleaned surface (it destroys the structure of paint-and-varnish and insulating coatings), and causes corrosion of metal surfaces. The presence of sodium tripolyphosphate in great amounts creates a threat of dangerous ecological consequences, since a high biological activity of ~ . ~
CA 021016~1 1998-04-08 phosphorus compounds exerts a destructive effect on flora and fauna of water reservoirs.
Still another agent for cleaning surfaces of resin-like fouling is known in the art (SU, A, 1325061). It contains primary alkyl sulfates (C13-C16) or primary alkyl sulfonates (C11-C17) as a surfactant, as well as calcium, bentonite, sodium carbonate, zeolite and a perfume additive. This agent is also sufficiently effective, however, it can produce a negative effect on the surface under washing, since it contains a great amount ~up to 80%
by mass) of abrasive (bentonite).
There exists an agent which is widely used in cleaning equipment of in-service fouling (oil, carbon black) (DE, C, 3517458). It contains a nonionogenic surfactant, zeolite and alkali additives: carbonate and bicarbonate of alkali metals. This agent has a narrow field of application.
Thus, for example, when cleaning electric machines with this agent, there is a possibility of depositing current-conducting sediments on the surface of insulation coatings.
Sufficiently effective is an agent which represents an aqueous zeolite suspension, stabilized with a mixture of surfactants (oxyethylated fatty alcohol TAS and KOAS). The agent also contains Na2O. However, in a number of cases this agent cannot be used for cleaning windings of electric ~"~
CA 021016~1 1998-04-08 machines owing to the formation of a current-conducting deposit (DE, A, 3330220). Besides, application of said anionic surfactants requires the use of water with reduced hardness and heating of the agent in the process of cleanlng .
Known in the art is still another agent for cleaning a metal surface of petroleum residues, which contains up to 15% by mass of surfactant: oxyethylated alkyl phenol or fatty alcohol and sodium alkyl sulphonate and up to 94% by mass of hydrocarbon solvent (SU, A, 541857). This agent efficiently washes off resin-like, heavy fouling. Prior to using this agent, it is recommended preliminarily to heat it up to a temperature of 50-60~C. The surface to be treated should also be heated up to this temperature. The agent is kept on the surface for 10-15 minutes, and then the surface is flushed with an aqueous solution of tripolyphosphate (0.1-3.0% by mass) and oxyethylated alkyl phenol (0.1-1.0% by mass), heated to a temperature of 60~C.
Presence of a great amount of solvent renders it impossible to automate the cleaning process owing to an elevated fire hazard. The necessity of preliminary heating of a part to be cleaned and a high content of the surfactant is economically unfavourable. A high content of the hydrocarbon solvent is not desirable due to its ~ ~.,.
'',.._ toxicity and narcotic effect, especially in the process of hand cleaning.
Thus, an agent for surface cleaning, meeting all the requirements of a modern enterprise, is not known in the art.
The invention is based on the problem to provide such an agent for cleaning surfaces of different nature, which would possess a sufficiently high detergency within a broad range of temperatures, would be fire safe and non-toxic, and that it would be possible to use manually or in a mechanized way.
This problem is alleviated in that an agent is provided including a surfactant (and as such contains oxyethylated alkyl phenol and/or oxyethylated fatty alcohol), an alkali additive and water, which, according to the invention also contains alkyl phenols, with the following ratio of components, % by mass:
- oxyethylated alkyl phenol and/or - oxyethylated fatty alcohol 0.1-3.0 - alkyl phenol 0.005-0.03 - alkali additive 0.2-0.5 - water the balance.
As stated above, the agent for cleaning surfaces includes a surfactant - oxyethylated alkyl phenol and/or CA 021016~1 1998-04-08 oxyethylated fatty alcohol in the amount of 0.1-3.0~ by mass. Each of these components can form part of the agent individually or in any mixture of the selected components.
In the selected range of concentrations, in combination with other components of the agent, these surfactants possess good detergency. At a reduced concentration of the surfactant below minimum level, the quality of cleaning in the above-indicated range drops. Increase of the surfactant content above 3.0% by mass is not expedient, since in this case, at the increased consumption of the component, the cleaning action of the agent becomes not much more efficient. Besides, frothing is increased, which complicates mechanized cleaning.
Alkyl phenol, introduced into the agent composition, carries out a function of a codetergent. Even in small amounts, alkyl phenols improve solubilization of washed off fouling, which decreases a danger of a repeated fouling of the surface. At a decrease and increase of concentrations, indicated in the selected range, efficiency of the agent action is reduced.
As an alkali additive, use can be made of traditional additives for agents of this kind. For example, natural A;~
and synthetic zeolite3, sodium tripolyphosphate and sodium silicate can serve as such additives.
- Alkali additives in the selected amount of 0.2-0.5% by mass improve washing abilities of the surfactant, ensuring a soft alkali effect of the agent.
Besides, the proposed combination of surfactants with an alkali additive makes it possible to produce a synergistic effect, ensures a high quality of cleaning, without causing corrosion and destruction of the surface, even that having a paint-and-varnish coating. Additives can be used individually or in combination with each other.
In a number of cases, for example, in cleaning surfaces of certain lubricants and oils, which undergo changes at a high temperature and pressure, and of other kinds of heavy fouling (mazout, viscous petroleum fractions), it is recommended to add the agent for cleaning surfaces with a hydrocarbon solvent in an amount of 0.5-55.0% by mass of the general quantity of the agent components. As a hydrocarbon solvent, it is possible to use, for example, kerosene, white spirit, diesel fuel, gasoline or gas condensate.
Presence of the hydrocarbon solvent in the agent composition ensures efficient cleaning of the surface of the above-indicated kinds of fouling.
CA 021016~1 1998-04-08 Availability in the agent composition of simultaneously selected surfactants alkyl phenol and hydrocarbon solvent in particular, ensures the formation of a stable emulsion with a sufficiently high washing power.
In this case droplets of the hydrocarbon solvent are distributed in water, which retards evaporation of the solvent, owing to which fact fire hazard and toxicity of the agent drop considerably.
The content of the hydrocarbon solvent in excess of 55.0% by mass of the general amount of the agent components results in reducing the efficiency of action of the water-soluble part of the agent, and raises its toxicity and fire hazard.
The claimed agent for cleaning surfaces makes it possible to clean surfaces with a sufficiently high degree of cleanness. It can clean various metal, glass, polymeric and ceramic surfaces with a sufficiently good effectiveness of any kinds of fouling.
The agent is serviceable within a broad range of temperatures (25-90~C). Its application leaves no sediments on the cleaned surface, including those current-conducting, which makes it possible to use this agent for, e.g., cleaning the windings of electric machines.
-CA 021016~1 1998-04-08 Preparation of the agent requires no scarce and expensive raw materials and a great amount of solvent. The use of the claimed agent requires no preliminary heating of the agent and the surface to be cleaned.
The agent can be used for manual and machine cleaning of surfaces.
The agent can be multiply reused.
The agent can be subjected to reclamation and used in a closed-circuit system, which makes it possible to cut down the consumption of components of the agent, water, and to reduce the volume of industrial waste waters.
Oils washed off by means of the agent, in the process of depreservation can be reused.
The method of producing the agent for cleaning surfaces is technologically simple and is effected as follows.
The agent components in the selected amount are charged into a reservoir and thoroughly mixed until a homogeneous emulsion is obtained.
In case a hydrocarbon solvent is used, it is charged simultaneously with all the components.
The efficiency of the washing agent was determined as follows. The gist of the method consists in evaluation of residual fouling of the surface, washed off under definite g _ ,~
,~ ~
CA 021016~1 1998-04-08 technological conditions, of the preliminarily obtained fouling.
As a model of fouling, use was made of an industrial oil or mazout, which was applied onto the surface (metal, glass, polymeric) of a plate in the amount of 1-102 g/cm2;
the plates were kept for 5 hours, then washed off by means of an ultrasound unit during 5 minutes. The quantity of fouling remaining on the plate is determined by a weighing method. Cleaning is considered satisfactory, if the residual fouling does not exceed 1-10-4 g/cm2.
For better understanding of the present invention, given below are the following concrete examples.
Example 1:
The agent was prepared with the following ratio of components, % by mass:
oxyethylated decyl phenol -0.1 nonyl phenol - 0.005 zeolite NaA - 0.5 water the balance.
The agent was prepared by way of mixing the components.
The mixture was thoroughly mixed until a homogeneous emulsion was obtained. Efficiency of the effect of the prepared compound was evaluated according to the method described above. For this purpose, 10 standard glass ," .
CA 021016~1 1998-04-08 plates were preliminarily soiled with an industrial oil and then cleaned with the prepared compound.
The averaged result of cleaning the surface at a temperature of 25~C is 1-10-5 g/cm2, at a temperature of 40~C - 7.2-10-5 g/cm2, and at a temperature of 60~C -6.0-10- g/cm .
Examples 2-4:
Examples 2-4 are given in Table 1, wherein given are the compositions of the agent for cleaning the surface, the temperature at which the agent is used, and the results of cleaning the plates of industrial oil. The data are given in comparison with the known agent.

First, through a circular header, during suction of the compressor, fed into the blading section as a jet by means of the pump is the first composition for 1-2 minutes at idle turning-over of the set. 15 minutes later the system is washed with the second composition.
A visual inspection showed that the surfaces of guide vanes of turbo-generator sets were fully cleaned of oil-and-dirt deposits. The use of the agent made it possible to improve the turbine technical-and-economic indexes: with similar values of speed of the gas turbocompressor before and after washing (~7,200 rpm), there is observed an increase of the power turbine speed (by 30-60 rpm), the exhaust temperature drops by 8-12~C, an increase in power of the turbo-generator sets, as well as a drop in gas pressure at the machine inlet and outlet.

CA 021016~1 1998-04-08 As seen from Table 1, the proposed compositions ensure an efficient cleaning of fouling within a broad range of temperatures in comparison with the known agent, which is efficient enough only at a temperature of 45~C and above.
In case of cleaning surfaces of heavy fouling (mazout, lubricants), it is recommended to use a combination of the two compositions of the agent, the first of which contains a hydrocarbon solvent. The surface is cleaned in turn by the first and second compositions.
Example 5:
The fouling model was mazout.
The first composition of the agent, % by mass:
oxyethylated decyl phenol 2.0 oxyethylated dodecyl phenol 1.0 isononyl phenol 0.03 diesel fuel 55.0 sodium tripolyphosphate 0.20 water the balance After thoroughly mixing the agent components until a homogeneous emulsion was obtained, a soiled cast-iron plate was sunk therein, kept for 10-15 minutes, and then treated with the second composition.
The second composition of the agent, % by mass:
oxyethylated ionyl phenol 0.20 isononyl phenol 0.01 sodium tripolyphosphate 0.20 sodium silicate 0.30 water the balance.
The averaged results of ten experiments show that the quantity of fouling remained on the plate is 2.2-10-5 g/cm2.
Examples 6-9:
Examples are given in Table 2 , wherein shown are compositions for cleaning, the nature of the washed-off surface, and the results of cleaning. The fouling model is mazout.
