JPH1112067A - Water transfer to concrete member and decorative concrete member - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a concrete member, having a surface gloss and luster and further a feeling of a real thing without any foaming or strain on the surface by respectively specifying conditions in drying after undercoating, draining drying after water transfer and drying after top clear coating when carrying out the water transfer of a pattern such as a marble, a granite or a grain to a concrete member. SOLUTION: A concrete is allowed to stand at normal temperatures for about 20 min to evaporate the initial solvent and thereby suppress the foaming without being directly placed in a dryer and heated in drying of an undercoating after the undercoating. The temperature in the dryer is then regulated to 60-80 deg.C in the subsequent draining drying after the water transfer. The top coating is then preferably performed by recoating in many layers without thickly coating in a breath and the top coating is subsequently conducted by allowing the resultant member to stand at normal temperature for about 20 min before the drying and then heating the member in the dryer. A back sealing agent is preferably coated after drying the top clear to prevent the crazing, etc., by water absorption from the back surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described based on an example with reference to FIG. The base 1 is provided with a water storage section 2 at a lower portion of the base 1, and the water storage section 2 is partitioned into respective chambers also for reinforcement. The water storage unit 2 includes a cover member 3
Bonsai that is covered with various small trees,
Stones and sand are arranged.

After the base adjustment, a sealer is applied on the concrete whose base has been adjusted for waterproofing. This painting,
If the process is simplified, it will affect the finish of the product, so it is preferable to apply the coating several times.

Next, sealer drying is carried out at about room temperature. Regarding the drying time, the minimum time is determined as a matter of productivity, but about 5 to 10 minutes at room temperature is required as the minimum time. If left to dry any further, experiments have shown that there is no problem.

An undercoat is applied by mixing, for example, a 90L toned product with a thinner (trade name). This work is done faithfully according to the paint manufacturer's instructions.

When the undercoat is completed, the process proceeds to a drying undercoat drying step. This drying step is carried out carefully, as it has a considerable effect on the surface finish and performance of the product. It is important to immediately evaporate the initial solvent by applying a paint for the undercoating, immediately putting the product in a drying apparatus without applying heat, and leaving it at room temperature for about 20 minutes at room temperature. Thereby, foaming to the concrete surface is suppressed, and a beautiful surface finish is ensured.

When the undercoat drying is completed, the undercoat is polished. The polishing operation is performed after the completion of the undercoat drying and after the surface temperature of the concrete member coming out of the drying chamber has dropped to some extent.

The concrete member thus formed is then subjected to water transfer. After the PVA transfer film is floated in a water tank at a water temperature of about 20 ° C., xylene is applied to the film and water-transferred to a concrete substrate.

When the water transfer is completed, there is a draining and drying step next. In this draining drying, the drying temperature is important, and as a result of repeating the experiment many times, it was found that if the film was not dried within a certain temperature range, the film would be distorted. This makes commercialization impossible. The range of the temperature is approximately not less than 80 ° C. and not more than 80 ° C.
If the temperature is higher than 0 ° C., the film will be distorted. Also, 6
At 0 ° C. or lower, a long drying time is required and in a short time,
Distortion comes out.

When the draining and drying process is completed, a top clear coating process is performed. In this coating process, paint is mixed and applied according to the specifications of the coating manufacturer, but the problem is that instead of applying thickly at a stretch to prevent air bubbles, bubbles are generated by coating multiple layers Can be prevented by repeated tests. As a result, it becomes a thick coat finish with a glossy surface,
For example, when the transfer is marble, a heavy feeling can be obtained as the surface.

Next, the process proceeds to top clear drying. What is important in this drying step is to suppress foaming, and it has been found through repeated experiments that a preliminary preliminary step is required before drying in order to suppress foaming. That is, if the product is dried immediately after the top clear coating is completed, foam on the surface will be formed and the product value will decrease. As a result of various experiments, the product was allowed to stand at room temperature for about 20 minutes before drying, and then dried. It has been found that drying by applying heat within is preferred for a glossy surface finish.

After the drying step, the back surface of the concrete member is coated with a back seal agent. For example, a thinner is added to a lock one-liquid back seal agent (trade name) to dilute and paint (see FIG. 2). In this painting, as a result of trial production and testing, especially when used as building materials,
In winter, it was found that water was absorbed from the back, and it was found that it freezes due to freezing and causes cracking and peeling,
As a result, it is found that it is important to apply the sealant not only on the front surface but also on the back surface, since the material may be fatigued and damaged by the repetition.

When the drying is completed, the process of mist wiping is started. In this final step, the back seal agent mist adhering to the surface of the coating is wiped off.

Although the finish is tentatively performed at the above stage, if buffing is further performed, the gloss and luster of the surface of the concrete member appear and the finish becomes more realistic.

FIG. 2 shows a state where the finished decorative concrete members are stacked. Concrete member 1
On top of this, a sealer layer 2 and then an undercoat layer 4 are provided, and then a water transfer ink layer 7, a surface clear layer 9 and a back seal layer 11 are sequentially provided to constitute each decorative concrete member.

As described above, the decorative concrete member formed by the improved water transfer method has a realistic surface gloss and gloss without bubbles or distortion on the surface (see FIG. 3). . In particular, when a shadow image of granite, marble, or the like is water-transferred by the water transfer method of the present invention, a decorative concrete member having a realistic surface gloss and luster, and full of weight can be obtained.

[0027]

As described above, according to the method of transferring water to a concrete member of the present invention, a water transfer method most suitable for concrete having a surface gloss and gloss and having no foaming or distortion on the concrete surface was obtained.

The water transfer method for a concrete member according to the present invention is a water transfer method developed for transferring water to a concrete member, and a concrete member having a surface gloss and gloss can be obtained. Water transfer of images such as granite and marble for architectural use gives a realistic surface gloss and luster,
Further, a decorative concrete member full of weight is obtained.

Further, by applying the back seal coating, it is possible to obtain a water transfer method and a decorative concrete member having weather resistance and water resistance with respect to material fatigue caused by repeated water penetration and icing even in the rainy season and winter season.

Furthermore, since water is directly transferred to the concrete member and produced, it can be immediately conveyed and provided as a building material at a necessary site.

In addition, since water is transferred to concrete,
Its application range is wide, such as it can be applied to buildings and other civil structures and other structures such as monuments and monuments.
Further, the application range is not limited to not only the outer wall of the building but also a fence, an inner wall, a bathroom, and various facilities.
