The present invention relates to a method for forming a sticker-preventing coating film that is difficult to apply, and even if a sticker is applied, it is easy to peel off, either artificially or naturally. Conventionally, as a method of preventing stickers, for example, wrapping a plastic net around the bottom end of a utility pole has been carried out, but this in itself significantly impairs the aesthetic appearance, and the net is formed specifically for utility poles. Therefore, it cannot be applied to other columnar structures with different diameters.
It also has the disadvantage that it cannot be used on wide areas such as bridge piers and walls. The present invention solves the above problems and relates to a method for forming a coating film that is easy to apply and that can effectively prevent and remove stickers. That is, in the present invention, if necessary, an undercoat is applied to the surface of the building structure to prevent pasting, and a particle size of 100 μm is applied.
Apply a coating material with a viscosity of 60 to 700 poise (at 20°C) containing the following fillers, inorganic and/or organic binders, and diluents as main components so that the difference in height between convex and concave areas is 0.2 to 10 mm. It is coated on an uneven surface, and is further coated with 100 parts by weight of a film-forming resin, 5 to 80 parts by weight of silicone oil, a fatty acid obtained by hydrolysis of lanolin, and a mono- to tetrahydric alcohol having 2 to 20 carbon atoms. The present invention relates to a method for forming a sticker-preventing coating film, which comprises applying a top coat consisting of 1 to 50 parts by weight of an esterified product and a necessary amount of a diluting solvent. According to the above-mentioned method of the present invention, the painted surface that is formed has an uneven surface with a height difference of 0.2 to 10 mm, and it is difficult to apply the sticker smoothly on this surface. This has the effect of making it extremely difficult to attach the sticker because it becomes difficult to see. Furthermore, even if a sticker is attached, the coated surface is water repellent and the adhesiveness of the glue is poor, and the coated surface is uneven and the contact area is small, so the sticker can be easily peeled off either artificially or naturally. In the method of the present invention, first, if necessary, the surface of the building structure is prepared, and an undercoat is applied. Subsequently, a coating material containing a filler, an inorganic and/or organic binder, and a diluent as main components is applied onto an uneven surface with a difference in height between the convex portions and the concave portions of 0.2 to 10 mm. The application method is to adjust the above coating material to 60 to 700 poise, preferably 100 to 500 poise, and apply it on a stipple coating surface using an ordinary stipple roller having a flocked roll surface or a foamed roll surface. A method such as adjusting the coating material to preferably 100 to 500 poise and spraying it in an uneven pattern using a mortar coating gun can be used. At this time, the viscosity of the coating material, coating conditions, etc. are adjusted so that the height difference between the uneven surfaces is 0.2 to 10 mm. In particular, the number of convex parts is 5 to 10,000/
It is more effective to apply the coating to an area of 100 cm 2 , preferably 10 to 5000 pieces/100 cm 2 . If the difference in height is smaller than 0.2 mm, it becomes easier to apply the sticker smoothly, and the adhesion area between the sticker and the coated surface increases, making it easier to adhere. Number of convex parts is 4/
If it is less than 100 cm 2 , the same tendency increases, which is not preferable. On the other hand, even if the height difference is made larger than 10 mm, there is little improvement in the effect of preventing pasting, and on the contrary, it becomes difficult to form an uneven surface, resulting in a disadvantage that work efficiency is reduced. If the number of convex portions is more than 10,000 pieces/100 cm 2 , the same tendency increases, which is not preferable. Furthermore, if necessary, the vicinity of the top of the convex portion can be pressed flat with a roller or polished to make it flat and give an appearance with a different design effect. In particular, a height difference in the range of 0.5 to 3 mm is suitable for the purpose of the present invention. Next, a top coat is applied onto the uneven surface. As a coating method, a conventional liquid coating method such as spray coating, roller coating, brush coating, etc. can be used. The top coat is preferably applied to a dry film thickness of about 10 to 100 microns. If the film thickness is less than 10μ, it will not be possible to obtain a coating film with sufficient durability.
It becomes difficult to damage the adhesive properties of the glue over a long period of time. Further, even if the film thickness is made larger than 100 μm, no particular improvement in the effect of inhibiting the adhesion is observed, and on the contrary, there is a problem that the film tends to sag during painting and the painting workability is poor. As the undercoat paint, a paint commonly used as an undercoat paint for architectural structures can be used. The coating material for forming the uneven surface is mainly composed of a filler, an inorganic and/or organic binder, and a diluent. Fillers include precipitated calcium carbonate, precipitated barium sulfate, precipitated magnesium carbonate, barium carbonate, extender pigments such as talc, kaolin, gypsum, and chalk, and coloring pigments such as titanium oxide, red iron oxide, and metal powder; Aggregates such as silica sand and cold water sand can be typically used. The filler used in the present invention has a particle size of 100μ
The following are preferred. When the particle size of the filler is larger than 100μ, the filler tends to clump together in the coating material, making it difficult to coat in a uniformly dispersed state.As a result, the finished coated surface becomes mottled and the filling of the coating film becomes difficult. Areas where the material is clumped have an effect of preventing paper-sticking, but areas where there is little filler have almost no effect of preventing paper-sticking, and the appearance is also undesirably lacking. It is appropriate to add the filler in an amount of 30 to 80% by weight in the coating material; if the amount of the filler is less than this range, the physical strength of the coating film will deteriorate, the coating surface will become easily stained, and an uneven coating film will result. On the other hand, if the amount of filler is too large, the coating performance will deteriorate, which is not preferable. As the binder used in the present invention, those commonly used in paints and the like can be used. Inorganic binders such as Portland cement, silica sol, and sodium silicate; Lutzker dry resins such as phthalate resins, acrylic resins, and vinyl resins;
Typical examples include organic binders such as two-component curing resins such as acrylic urethane resin, polyester urethane resin, unsaturated polyester resin, and epoxy resin, and thermosetting resins such as melamine-phthalate resin and melamine-acrylic resin. It can be used as something. In addition, diluents used in the present invention include water, mineral spirits, lower alcohols, toluene, xylene, etc., which are commonly used in paints.
It is selected as appropriate depending on the type of binder and the material of the building structure. The coating material may further contain additives such as a thickener, a surfactant, and a preservative, if necessary. The viscosity of the coating material used in the present invention differs slightly depending on the coating method, but usually the viscosity at 20℃
60 to 700 poise is appropriate. If the viscosity of the coating material is higher than the above range, coating workability becomes difficult, and if it is lower, it becomes difficult to obtain a coating film with an uneven surface, which is not preferable. As mentioned above, the coating material used in the present invention is
Large aggregates are not used, and the coating film is uneven due to the coating material itself, not the aggregate, resulting in a uniform, fine-grained, tile-like uneven coating with excellent aesthetics. It will be done. Next, the film-forming resin used for the above-mentioned top coat is a film-forming resin that is usually used for the top coat of architectural structures, such as lacquer drying resins such as phthalic acid resins, acrylic resins, and vinyl resins; acrylic Urethane resin, polyester urethane resin,
Two-component curing resins such as unsaturated polyester resins and epoxy resins; thermosetting resins such as melamine-phthalic acid resins and melamine-acrylic resins can be used. The silicone oil mentioned above is liquid at room temperature. Specific examples include dimethylsiloxane derivatives, methylphenylsiloxane derivatives, methylalkylsiloxane derivatives, methylvinylsiloxane derivatives, and methylhalogenated alkylsiloxane derivatives. The silicone oil is used in an amount of 5 to 80 parts by weight based on 100 parts by weight of the film-forming resin. If the amount of silicone oil is less than 5 parts by weight, the effect of inhibiting the adhesion of the sticker will be insufficient, and if it is more than 80 parts by weight, it will be difficult to mix homogeneously into the paint.
Furthermore, the surface of the paint film becomes wet and easily becomes dirty due to adhesion of dust, which impairs its aesthetic appearance. In addition to the above top coat, fatty acids obtained by hydrolysis of lanolin and 1- to 2-20 carbon atoms are added.
By adding an esterified product with a tetrahydric alcohol, the peelability of the sticker can be further improved. The esterified product is preferably added in an amount of about 1 to 50 parts by weight per 100 parts by weight of the film-forming resin. If the amount added is less than 1 part by weight, the effect of improving the above-mentioned releasability will be small, and if the amount added is more than 50 parts by weight, no significant improvement in releasability will be observed, and on the contrary, the hardness and stain resistance of the coating will decrease. This has the disadvantage of lowering the In particular, the esterified product has an acid value of 10 or less, OH
Compounds with a value of 100 or less are preferred. In addition, the architectural structures to be painted in the present invention are generally the exterior walls of buildings, exterior walls of houses, and
Materials such as fences, bridge piers, utility poles, etc., and precast concrete, slate plates, steel plates, etc. used for these parts, and whether painted on site after construction or painted at the factory during the manufacturing process of the materials, this is the standard. The invention can be applied. The present invention will be explained below with reference to Examples. In the Examples and Comparative Examples, the difference in height of the uneven surface was measured by adjusting the focus of an optical microscope (with an error of ±1 μm) at 10 locations between a convex portion and an adjacent concave portion. Example 1 Coating material composition (viscosity 350 poise) (unit: parts by weight) Acrylic emulsion (50wt% water dispersion) 20 parts silica sand (particle size 74μ or less) 40 parts calcium carbonate (particle size 35μ or less) 20 parts water 15 0.5 parts Hydroxyethyl cellulose 4.5 parts Titanium white Apply the above coating material on an asbestos slate board with a mortar paint gun and dry it until the difference in height between the convex and concave areas is 4~4.
An uneven surface with a thickness of about 5 mm and a number of protrusions of about 200/100 cm 2 was formed. Liquid silicone oil for acrylic urethane resin paint [Product name Silicone TSF451; Toshiba Silicon Corporation
] and an esterified product of lanolin fatty acid and stearyl alcohol (acid value: 3, OH value: 50) to prepare a top coat of film-forming resin, liquid silicone oil, and the above esterified product in a weight ratio of 100/10/5. death,
This paint was spray-painted on the uneven surface to form a top coat with a dry thickness of about 40 μm. Example 2 Coating material composition (viscosity 280 poise) Acrylic emulsion (50 wt% water dispersion) 14 parts Calcium carbonate (particle size 35μ or less) 65 parts Titanium white 7 parts Methyl cellulose 0.5 parts Water 13.5 parts The above was applied on an asbestos slate board. Apply the coating material with a stipple roller, dry it, and the difference in height between the convex and concave areas is 2.
An uneven surface with a thickness of about 3 mm and a number of protrusions of about 500/100 cm 2 was formed. Liquid silicone oil [trade name Silicone KP356; manufactured by Shin-Etsu Chemical Co., Ltd.] and an esterified product of lanolin fatty acid and pentaerythritol (acid value 5, OH value 80) are added to the vinyl resin paint to form a film-forming resin and liquid silicone oil. The weight ratio of the above esterified products is 100/5.
A 0/30 top coat paint was prepared, and this paint was applied to the uneven surface with a roller to form a top coat film with a dry film thickness of about 15 μm. Example 3 Coating material composition (viscosity 260 poise) Non-aqueous acrylic resin emulsion (50 wt% mineral spirit dispersion) 26 parts talc (particle size 43μ or less) 10 parts calcium carbonate (particle size 35μ or less) 50 parts titanium white 3 parts Organically modified bentonite 1 part Mineral spirits 10 parts Apply acrylic resin paint and apply the above coating material on the asbestos slate board using a stipple roller. After drying, the difference in height between the convex and concave parts is about 5 to 7 mm. In addition, an uneven surface with approximately 50 protrusions/100 cm 2 was formed. Liquid silicone oil for acrylic urethane resin paint [Product name Silicon TSF456; Toshiba Silicon Corporation
] and an esterified product of lanolin fatty acid and ethylene glycol (acid value: 10, OH value: 10) to prepare a top coat of film-forming resin, liquid silicone oil, and the above esterified product in a weight ratio of 100/20/2. This paint was spray-painted on the uneven surface to form a top coat with a dry thickness of about 30 μm. Comparative Example 1 Coating was carried out in the same manner as in Example 1, except that the weight ratio of the film-forming resin, liquid silicone oil, and esterified product in the top coat was 100/3/0.5. Comparative Example 2 Coating was carried out in the same manner as in Example 2, except that the weight ratio of the film-forming resin, liquid silicone oil, and esterified product in the top coat was 100/90/0.5. Comparative Example 3 The same procedure was used as in Example 3, except that 10 parts of mineral spirits were added to the coating material to make the viscosity 50 poise, and the height difference between the convex and concave portions was approximately 0.1 to 0.2 mm, and the number of convex portions was approximately 10,000. An uneven surface of 100 cm2 was formed.
A top coat was applied thereon under the same conditions as in Example 3 to form a top coat with a dry film thickness of approximately 5 μm. Comparative Example 4 Coating material composition (viscosity 50 poise Note 1) Acrylic emulsion (50 wt% water dispersion) 20 parts Silica sand (particle size 1-2 mm) 60 parts Water 15 parts Hydroxyethyl cellulose 0.5 parts Titanium white 4.5 parts Note 1 Silica sand Because of the precipitation, the paint was not uniform and the viscosity could not be measured accurately. Coating was carried out in the same manner as in Example 1 except that the above coating material was used. However, the coating film had a non-uniform finish with some silica sand lumps in some parts, but the other part was almost smooth. Painted boards created in each of the above examples and comparative examples,
After soaking these in tap water for about 30 days, a 5 x 10 cm 2 dry copy paper was attached to the painted board using commercially available starch glue or synthetic glue, and a rooftop exposure test was conducted.
The test results are shown in Table 1. (The numbers in the table indicate the number of days after the copy paper is pasted until it naturally peels off.)
