Abstract

(57) [Problem] To provide an antifouling fiber-reinforced plastic waterproof material structure which is hardly stained even when used outdoors for a long period of time, and which maintains its original appearance for a long time without cleaning work. SOLUTION: In the surface layer of the fiber reinforced plastic waterproof,
A self-cleaning property is imparted by a waterproof structure provided with a layer containing a titanium oxide photocatalytic functional substance (antifouling top coat layer).

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a structure of a fiber-reinforced plastic (FRP) waterproof material used for a balcony or a flat roof of a building.

[0002]

[Prior art]

 The conventional FRP waterproofing material is made by impregnating the base surface with a fiber-reinforced material such as glass fiber and a laminating resin such as an unsaturated polyester resin by in-situ lining, and then hardening to form a main waterproofing layer. In order to protect the main waterproof layer and to impart aesthetic appearance, a colored resin layer (top coat layer) is further applied and cured to finish.

[0003]

[Problems to be solved by the invention]

 Since conventional FRP waterproofing materials are generally used outdoors, dust and various contaminants in the air gradually adhere to the surface over time, and the appearance gradually deteriorates. For this reason, maintenance work such as washing with detergent is indispensable to maintain good aesthetics, which is very troublesome, and there is a risk of damaging the waterproof surface each time cleaning is performed.

The present invention has been made to solve such problems of the prior art. By providing a self-cleaning function to the top coat layer, the maintenance work such as cleaning is hardly required, and the initial work is not required. Aesthetics are preserved.

[0005]

[Means for Solving the Problems]

 To achieve the above object, the FRP waterproofing material of the present invention is self-cleaning (antifouling) by adding a titanium oxide photocatalytic functional substance to the coating material in advance when applying and forming the surface topcoat layer. G) A FRP waterproof material structure having a function is obtained.

[0006] The dirt substance in the air generally has an adhering substance such as oil on the surface layer, and it has a strong adhesion to the waterproof material. On the other hand, the titanium oxide photocatalytic functional substance can decompose almost any organic compound by irradiating light, and thus decomposes the oil adhering to the surface layer of such contaminants. As a result, the adhesion of the dirt substance to the waterproof material is lost, and the substance is easily dropped by rainwater or the like.

[0007] Since the titanium oxide photocatalytic functional substance is generally in the form of a fine powder, it can be uniformly dispersed in a coating material. It is possible to

[0008]

[Embodiment of the invention]

 The final embodiment of the present invention is as shown in FIG. 1. First, the procedure for forming the present invention will be described.

In general, fireproof boards such as mortar, plywood, and wood chip cement boards are used as waterproof base materials. First, in order to increase the adhesive strength between the base material and the waterproofing material, a resin liquid called primer 3 is uniformly applied at a rate of 0.2 kg / m ² as a guide, and left to cure until a touch-dry state is obtained. Let it.

Next, as an undercoat resin layer, an unsaturated polyester resin solution containing about 1% of a curing agent added and mixed is applied as a guide at 0.6 kg / m ^2. Lay down a dostrand mat (glass mat). Further, the above resin solution is applied as a top coating resin from above the glass mat at a rate of 0.9 kg / m ² as a guide, impregnated into the glass mat through a defoaming operation, integrated and cured. At this time, the count (thickness) and type of the glass mat to be used, and the amount of resin thereby may be changed arbitrarily.

After the formation of the main FRP waterproof layer, a resin liquid is applied as an intermediate resin layer at a standard of 0.4 kg / m ² and cured. However, this step may be omitted. After that, finally, a resin solution of the antifouling top coat containing the titanium oxide photocatalytic functional substance is uniformly applied and cured at a standard of 0.4 kg / m ² .

The amount of the titanium oxide photocatalytic functional substance (fine powder) added to the antifouling top coat is generally in the range of 0.1% to 10%, and preferably 1% to 3%.

[0013]

[Effect of the invention]

 Since the present invention is configured as described above, it has the following effects.

[0014] Since dirt such as water scale due to rainwater is hardly attached, and even if it adheres, it easily flows down with rainwater, so that the original appearance can be maintained for a long time without maintenance such as cleaning.

In addition, since the present invention is generally used outdoors, it can be expected that various harmful substances in the air are decomposed and made harmless by the organic substance decomposition action of the titanium oxide photocatalytic functional substance.
