BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover plate which is mainly used by being attached to a snow ditch or a water facility and can be used as a floor material or a wall material of a building or the like.

[0002]

2. Description of the Related Art Conventionally, synthetic resin paints are often applied to the inner surfaces of snow drifts and reservoirs or roofs and walls of buildings to prevent water leakage and deterioration.

[0003]

However, when the coating work is performed on site, the paint adheres to the neighborhood and the clothes of the worker, and in the spray painting, there is a possibility that the scattered paint may be inhaled. The bad working environment cannot be denied. or,
There was a problem that the work efficiency was poor because the tools used for painting work had to be relatively small.

The present invention has been made in view of the above circumstances, and prevents pollution near the site due to painting work, improves the working environment, and prevents leakage and deterioration of buildings and water facilities with high workability. The purpose is to provide a cover plate that can take measures.

[0005]

The surface mounting plate according to the present invention made to solve the above problems is characterized in that a coating layer made of a synthetic resin is formed on the surface of an elastic sheet. As the coating layer, a coating layer made of polyurethane resin coated without mixing a solvent and having a thickness of 0.5 mm to 3 mm may be adopted, and an adhesive for fixing to a location on the back surface of the elastic sheet. You may form a layer.

[0006] That is, in a factory or the like, a cover plate formed by previously forming a coating layer on the surface of an elastic sheet is produced, and the cover plate is arranged on an adherend at the site, so that the coating work at the site can be performed. By avoiding this, the work environment and workability are improved, and by using an elastic sheet as the base that forms the coating layer, the adhesiveness to the adherend and the followability to the deformation of the adherend are improved, and no solvent is mixed. Made of polyurethane resin with a thickness of 0.5
By adopting a coating layer having a thickness of 3 mm to 3 mm, the coating layer itself is made to have elasticity so as to prevent breakage or peeling of the cover plate. Further, by forming an adhesive layer on the back surface of the elastic sheet for fixing it to the location where the elastic sheet is provided, the work of applying the adhesive is omitted and the workability is further improved.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An example of an embodiment of a cover plate according to the present invention will be described in detail below with reference to the drawings. In the first embodiment, a coating layer 2 made of a polyurethane resin coated without mixing a solvent is formed on the surface of an elastic sheet 1. When a polyurethane resin that does not contain solvent is coated, it quickly dries and solidifies without pinholes, blisters, or craters, and the finished surface is smooth, durable, wear-resistant, water-resistant and It is possible to form a good quality coating layer 2 having all the water permeability. Further, it is possible to apply a thickness of 500 μm to several cm by a single application such as brush coating, flow coating or spray coating with a special coating machine. Specifically, polyol resin (55%), color pigment (33%), extender pigment (3
%) And an additive (9%) and a modified isocyanate resin (100%) curing agent at a volume ratio of 3: 1, which is a two-component solventless polyurethane resin paint. Mizeron S-100 / A-1000 (manufactured by Mitsui Metal Coating Chemicals Co., Ltd .... hereinafter referred to as Mizeron) is known.

In order to obtain a surface mounting plate having the above-mentioned Mizeron as the coating layer 2, a partition 5 is placed on a mold 6 formed by standing a partition 5 having a height approximately equal to the film thickness of the Mizeron on a glass flat plate 4. Spray the mizeron up to the height of the elastic sheet 1 from above
Is gradually laid from the end with the roller 7 and laid. After about 1 hour, a very basic surface mounting plate having a coating layer 2 having a uniform film thickness is completed by peeling the glass plate 4 while applying hot air of 40 ° C. to 50 ° C. to the back surface thereof. When the film thickness is not required to be uniform, other coating means such as spray coating may be used.

The fixing means of the cover plate differs depending on the adherend, but in general, the elastic sheet 1 is used for a wooden surface or a metal surface.
Use, for example, a structure in which a neoprene-based adhesive is applied to the back surface of the sheet and a release paper 8 is attached on the adhesive layer 3, or a strong double-sided tape is attached to the back surface of the elastic sheet 1. Then, it is cut appropriately and the release paper 8 is peeled off and attached. In order to increase the strength, the adhesive may be applied not only to the back surface of the elastic sheet 1 but also to the adherend. As a result of the elastic sheet 1 being interposed between the adhesive applied to the adherend and the covering layer 2, the followability to the deformation of the wood due to the expansion of the metal due to heat or the drying and the like is increased, and the thinner mixed in the adhesive is used. It is also possible to prevent the adverse effects of the above on the quality of the material of the coating layer 2. For example, the Mizeron is a material that is easily altered by thinner.

When it is attached to a portion such as concrete 9 which is hard to be fixed, a surface mounting plate composed only of the elastic sheet 1 and the covering layer 2 is used, and an epoxy resin type adhesive is applied to the adhered surface after the base treatment. Apply the agent and stick. When the concrete 9 is an adherend, when the temperature rises, the water content of the concrete 9 itself becomes water vapor 10 and tries to be pushed out of the coating layer 2. However, if the temperature between the coating layer 2 and the concrete 9 is increased, If the elastic sheet 1 does not exist in the above, and the coating layer 2 is made of a material having a very small porosity such as Mizeron, the water vapor 10 accumulates at the boundary between the concrete 9 and the coating layer 2 and peels off at that portion. Will result. On the other hand, in the present invention, since the elastic sheet 1 is sandwiched, the force that the steam 10 tends to push out is dispersed, and the effect becomes more remarkable as the porosity of the elastic sheet 1 is higher. As a result, it is possible to obtain good results with respect to the conformability to deformation and the like and the adhesion to the adherend surface having irregularities, and it is possible to prevent peeling of the coating layer 2 (see FIGS. 8 and 9). .

In particular, when it is used on the wall surface of a building, one of the paired joints is formed on the back surface of the elastic sheet 1 and the other is fixed to the wall surface of the building so that the two joints are formed. You may make it the structure which engages.

If a cover plate having a coating layer 2 made of migeron is provided in a snow drift groove or a reservoir, its smoothness allows snow and dust to flow extremely well without being caught in the middle of the groove, resulting in high protection. Also exerts algae effect. The elastic properties of the coating layer 2 and the elastic sheet 1 are combined to exert strong adhesion to the adherend and a reliable sealing effect. When a higher sealing effect is required under more severe conditions, rubber having water-swelling property is selected as the material of the elastic sheet 1, so that the rubber expands its volume due to its inherent elasticity. In addition, the gap can be sealed with a strong force to increase the water stop pressure. Moreover, since the coating layer 2 having good wear resistance is formed on the surface and the coating layer 2 also has a high followability to the expansion of the elastic sheet 1, the elastic sheet 1
However, it does not lose its appearance and function. Further, if it is arranged on the roof of a building, it becomes difficult for snow to collect, and sticking to a tool such as a hopper that handles powdery materials can prevent sticking. Other than that, shells, barnacles, etc. do not easily adhere when attached to a ship, and even if they adhere, they can be easily peeled off. Utilizing the lubricity of the coating layer 2 made of polyurethane resin coated without mixing solvent. The use is extremely wide.

In addition, if it is spread on a floor or a sidewalk, it is possible to create an environment in which the elasticity of the floor and sideways is different from the feel of asphalt or concrete, and the burden on the legs and waist is small. If unevenness is formed, unevenness is formed on the surface of the coating layer 2 and the inherent lubricity is removed, so that the foot is less likely to slip, and the unevenness can form a picture pattern. If so, the decorative effect of the cover plate also increases. When it is desired to enhance the appearance, the fluororesin paint can be applied and colored in a thickness of 30 to 60 μm, or if the fluororesin paint is applied without providing unevenness,
The smoothness is enhanced and the weather resistance is enhanced.

For the coating layer 2, an acrylic resin coating layer 2 may be formed in addition to the polyurethane resin coating material in which no solvent is mixed. In this case, the flat sheet-shaped cover layer 2 is bonded to the elastic sheet 1. The acrylic resin coating layer 2 is less stretchable than the coating layer 2 made of the polyurethane resin coating, but is a material that is easy to process and inexpensive. Similar to the polyurethane-based resin coating layer 2, it has appropriate lubricity, and among them, there are those that have been improved to add heat resistance and impact resistance. It is also possible to form the coating layer 2 of epoxy resin or polyvinyl chloride resin and attach it to the elastic sheet 1. Also in this case, the elastic sheet 1 which adheres strongly to the adherend and has elasticity even though the covering layer 2 has poor elasticity plays a role as a cushioning material between the adherend and the covering layer 2. Shows a high peel strength.

The shape of the cover plate according to the present invention may be molded or cut according to the intended use. However, if the end faces are provided with grooves or ridges which fit with each other, the peeling prevention effect and the water leakage prevention effect can be obtained. Higher. The elastic sheet 1 used for the cover plate according to the present invention is preferably a material having elasticity such as rubber and having a high porosity, and synthetic rubber such as natural rubber or EPR (ethylene propylene rubber) or a foamed resin is considered. However, depending on the case, heat resistance, weather resistance, etc. may be required, and it may be appropriately selected according to the application in consideration of the characteristics of the material.

[0016]

As described above, by using the face plate according to the present invention, it is possible not only to improve the work environment and workability by avoiding the painting work on site, but also to avoid the contamination around the site. Furthermore, the elastic sheet serving as the base of the coating layer suitably follows the deformation of the adherend and strongly adheres to the adherend, preventing clogging of the snow drift groove and preventing ice formation on the groove wall surface. Furthermore, it has remarkable practical effects in various applications, including measures to prevent water leaks in water facilities.
