(a) Purpose of the invention [Field of industrial application] The present invention relates to a cleaning composition, and in particular,
The present invention relates to a cleaning composition used to clean surfaces of objects contaminated with air pollutants such as dust. [Prior Art] Conventionally, cleaning surfaces of objects that have been contaminated by air pollutants such as soot and dust has had various problems, such as the impact on surface coatings and ease of use, making it impractical. There was no cleaning agent available. For example, paint films used on surfaces such as chimney exterior walls, guardrails, and building walls have been able to maintain their functionality for quite a long time due to improvements in film performance (weather resistance, etc.). Even with various coating films,
Depending on the environment in which it is exposed, various types of dirt (air pollutants, etc.) may adhere to the surface, which may cause problems with the appearance or require repainting within a shorter period than the original service life of the paint film. Something happened. However, repainting requires a large amount of money, so a method that only removes surface dirt has been desired, but it does not affect the paint film and can be used in places where cleaning is difficult, such as the outer wall of a chimney. A cleaning composition with good workability has not yet been put into practical use. [Problem to be Solved by the Invention] The present invention can remove contaminants from the surface of an object that has been contaminated by air pollutants such as soot and dust, and furthermore, can remove contaminants from the surface of an object that have been contaminated with air pollutants such as soot and dust, and can further reduce the effect on the coating film on the object surface. The present invention has been completed through intensive research into a cleaning composition that is easy to work with and does not cause any sagging even when applied to vertical surfaces. (B) Structure of the Invention [Means for Solving the Problem] The present invention is a cleaning composition for objects contaminated with air pollutants, which is composed of methylene chloride and a vinyl resin. Methylene chloride has the function of dissolving or swelling the dirt on the surface of objects and the vinyl resin that is the vehicle component in the cleaning composition. The vinyl resin provides the cleaning composition with a desirable viscosity, improves its applicability to the surface, and also has the function of enveloping dirt removed from the surface. Preferred examples of vinyl resins include those containing vinyl chloride resin or vinyl acetate resin as a component. Specific examples include vinyl chloride resin, vinyl chloride mono-vinyl acetate copolymer resin, ethylene-vinyl acetate copolymer resin, etc. vinyl acetate copolymer resin,
Examples include vinyl acetate-vinyl chloride-ethylene copolymer resin. In order to further enhance the action and effect of the cleaning agent made from the composition of the present invention, the following substances can be added as necessary. ○B. A solvent with a boiling point higher than that of methylene chloride and which does not dissolve or swell the vinyl resin (hereinafter referred to as a high-boiling point poor solvent).○B.A low-boiling point ketone.○C.A low-boiling point alcohol.○Nipara fine wax. Even after the cleaning composition is applied to the surface of an object and the methylene chloride has evaporated, the solvent remains along with the vinyl resin, making it easier to wipe the vinyl resin that envelops dirt from the surface of the object more effectively. I will make you do it. The high boiling point poor solvent has a boiling point higher than that of methylene chloride, preferably 50°C, more preferably 100°C or higher, and can be selected from a wide range as long as it does not dissolve or swell the vinyl resin. Preferred specific examples include petroleum fractions such as kerosene and light oil, hydrocarbon solvents such as hexane and octane, methyl cellosolve, butyl cellosolve,
Examples include glycol ethers such as butyl carbitol. Low boiling point ketones have the same effect as methylene chloride, but because they have a higher boiling point than methylene chloride, they are particularly suitable for use when applying a cleaning composition to the surface of a high temperature object. However, if a large amount of this substance is contained, the cleaning composition becomes flammable, which is not preferable. The low boiling point ketone is not particularly limited, but preferably has a boiling point of 150°C or lower, more preferably 120°C or lower, and preferable specific examples include acetone, methyl ethyl ketone,
Examples include methyl isobutyl ketone. In particular, methyl ethyl ketone is most preferably used in the present invention due to its boiling point and flash point. Low-boiling alcohols have a synergistic effect when used with the composition of the present invention in removing dirt, particularly inorganic or ionic dirt, from surfaces of objects. Although low boiling point alcohols are not particularly limited,
Preferably the boiling point is 150℃ or less, more preferably 120℃
℃ or less, and specific examples of suitable examples include methanol, ethanol, propanol, and butanol, and i-propanol is particularly preferably used. Parafine wax suppresses the evaporation of methylene chloride and low boiling point ketones, further prolonging the cleaning effect. When the surface of an object is wiped with a cleaning composition, the inorganic powder is more effective in physically polishing the surface to remove stuck dirt, and is also more effective in reducing sagging when the cleaning composition is applied. prevent it from happening. Specific examples include powders of diatomaceous earth, alumina, talc, silica, clay, and the like. The particle size of the inorganic powder is preferably 10 to 200 mesh, more preferably 50 to 100 mesh. If the number exceeds 10 meshes, the paint film may be damaged or the wiping operation may not proceed smoothly, and if the number is less than 100 meshes, the grinding action may deteriorate. In the present invention, methylene chloride, a high boiling point poor solvent added as desired, a low boiling point ketone, a low boiling point alcohol (hereinafter referred to as a solution consisting of methylene chloride), a vinyl resin and a paraffin wax added as desired The blending ratio of the inorganic powder is not clearly limited and can be changed depending on the surface properties of the object to which it is applied, the nature and degree of contamination, etc., but the composition to achieve general performance. The preferred ranges are as follows. The solution consisting of methylene chloride preferably contains 40 to 100% by weight of methylene chloride, more preferably 60 to 94% by weight, 0 to 30% by weight of a high-boiling point poor solvent, more preferably 5 to 15% by weight, and 0 to 30% by weight of a low-boiling point ketone. % by weight, more preferably 5-20% by weight, 0 low-boiling alcohols
-10% by weight, more preferably 1-7% by weight. If the high-boiling point poor solvent exceeds 30% by weight, it will be difficult to dissolve in the vinyl resin, and if the low-boiling point ketone exceeds 30% by weight, there is a risk of flammability.
Furthermore, even if more than 10% by weight of low-boiling alcohol is blended, the associated effects may not be expected. The blending ratio of the solution consisting of methylene chloride, vinyl resin, paraffin wax added as desired, and inorganic powder (hereinafter referred to as the present cleaning composition) is preferably 60% of the solution consisting of methylene chloride in the present cleaning composition. -99% by weight, more preferably 80-97% by weight, vinyl resin 1-30% by weight,
More preferably 3 to 15% by weight, paraffin wax 0 to 5% by weight, even more preferably 0.1 to 4% by weight,
Inorganic powder 0-15% by weight, more preferably 1-12%
Weight%. If the vinyl resin content is less than 1% by weight, no effect may be expected, and if it exceeds 30% by weight, fluidity may deteriorate and workability may deteriorate. Even if the paraffin wax exceeds 5% by weight, the associated effects may not be expected, and if the inorganic powder exceeds 15% by weight, the viscosity may increase. In the cleaning composition of the present invention, the vinyl resin is in a state dissolved or swollen in methylene chloride, and the method for producing the composition of the present invention is not particularly limited. Mix a poor solvent, a low boiling point ketone, and a low boiling point alcohol, add a vinyl resin, optionally paraffin wax, and inorganic powder to the methylene chloride solution, fill and stir to form a uniform solution or slurry. good. In this case, if you heat the whole thing further,
It is desirable because it promotes the dissolution and swelling of vinyl resins, paraffin waxes, etc. When the cleaning composition of the present invention is applied to the surface of a contaminated object, for example, it is applied to a cloth or the like and impregnated, and the surface of the object is rubbed to remove dirt, or the surface of the object is first applied with a brush, roller, etc. Simply apply it to the area and wipe it off with a cloth after a while. The applicable object is particularly useful for objects contaminated with air pollutants such as smoke and dust, such as chimney outer walls, guardrails, and building walls, and when the object is coated with a paint film, It can be applied particularly effectively. Preferred examples of the paint film to be applied include condensation resins such as polyurethane resins, epoxy resins, melamine resins, silicone resins, and polyamide resins, and polymerization resins such as vinyl chloride resins. Examples 1 to 10 and Comparative Examples 1 to 4 Various cleaning compositions of the present invention were produced, and their performance was compared with conventionally known cleaning compositions. The result is the first
Shown in the table. The test was conducted using the following method. The outer wall of a chimney (approximately 100m high) coated with a paint film (specially modified polyurethane resin paint Compo R (product name: Nippon Paint Co., Ltd.)) from a certain waste incineration factory was damaged by tar or dust in the soot and smoke. The surface was heavily contaminated. The detergent composition according to the present invention and various conventionally known detergents were applied to a rag and the stains on the wall surface were wiped to determine the degree of cleaning of the surface. The outer wall surface temperature was 35°C to 70°C. Note that the paint film after being cleaned using the composition of the present invention was not affected in any way.
