Abstract
Description
本発明は、建物の外壁に形成され、防カビ及び／または防藻性を有し、該外壁周辺の植栽を枯らすことがない塗材仕上げ構造、及び塗材仕上げ工法に関する。 The present invention relates to a coating finishing structure that is formed on the exterior wall of a building, has anti-mold and/or anti-algae properties, and does not kill plants around the exterior wall, and a coating finishing construction method.
従来、建物の外壁等に形成される塗材仕上げ構造は、下地調整材又は下塗り材、必要に応じて中塗り材、及び上塗り材を用いて仕上げられる。これらの塗材が水系であると塗材仕上げ表面にカビや藻が繁殖して意匠性が損なわれる場合があるが、上塗り材に防カビ剤や防藻剤を配合することで防いでいる。例えば、特許文献１では、合成樹脂エマルジョン、充填剤、顔料、増粘剤、分散剤、防カビ剤、防藻剤を少なくとも含む水系塗材であって、ホルムアルデヒド、トルエン、キシレン、パラジクロロベンゼン、エチルベンゼン、スチレンの揮発性有機化合物を含まない有機溶媒を含むことを特徴とする塗材組成物が開示されている。 BACKGROUND ART Conventionally, a coating material finishing structure formed on the outer wall of a building, etc., is finished using a base conditioning material or an undercoat material, and if necessary, an intermediate coating material and a top coating material. If these coating materials are water-based, mold and algae may grow on the finished surface of the coating material, impairing the design, but this is prevented by adding mold and algae inhibitors to the top coating material. For example, Patent Document 1 discloses a water-based coating material containing at least a synthetic resin emulsion, a filler, a pigment, a thickener, a dispersant, a fungicide, and an algaecide, and which includes formaldehyde, toluene, xylene, paradichlorobenzene, and ethylbenzene. , discloses a coating composition characterized in that it contains an organic solvent that does not contain a volatile organic compound of styrene.
しかしながら、特許文献１の塗材組成物のように、上塗り材として使用する塗材組成物単体で防カビ性や防藻性を得ようとすると、防カビ剤や防藻剤の配合量、それらの成分、該塗材組成物が施工される外壁とその周囲の植栽との距離、等の諸条件によっては該植栽が枯れる場合があるという課題があった。 However, when trying to obtain antifungal and algae-proofing properties from a single coating material composition used as a top coating material, such as the coating material composition of Patent Document 1, the amount of the antifungal agent and the antialgal agent, There has been a problem in that the plants may wither depending on various conditions such as the components of the paint composition, the distance between the outer wall on which the coating material composition is applied and the surrounding plants.
そこで本発明が解決しようとする課題は、防カビ及び／または防藻性を有し、周囲の植栽を枯らすことがない塗材仕上げ構造、及び塗材仕上げ工法を提供することにある。 Therefore, the problem to be solved by the present invention is to provide a coating finishing structure and coating finishing construction method that has antifungal and/or antialgal properties and does not kill surrounding plants.

To provide a coating material finishing structure characterized by forming a coating material.
また請求項２記載の発明は、下地の上、あるいは、該下地にシーラーを塗付して乾燥させた上に、
アクリル樹脂系エマルジョンと、充填剤と、骨材と、顔料と、増粘剤と、成膜助剤と、防カビ及び／または防藻剤と、を含む水系下地調整材組成物であって、防カビ及び／または防藻剤は組成物１００重量部中０．３～１．０重量部である水系下地調整材組成物を塗付して水系下地調整材組成物層を形成し、
この上に、アクリル樹脂系エマルジョンと、充填材と、骨材と、顔料と、増粘剤と、成膜助剤と、を含む水系塗材組成物であって、更に防カビ及び／または防藻剤を組成物１００重量部中１．０重量部未満含む、または、防カビ及び／または防藻剤を含まない水系塗材組成物を、少なくとも１回塗付して水系塗材組成物層を形成することを特徴とする塗材仕上げ工法を提供する。
In addition, the invention according to claim 2 provides a method for applying a sealer on a base, or applying a sealer on the base and drying the base.
An aqueous base conditioner composition comprising an acrylic resin emulsion, a filler, an aggregate, a pigment, a thickener, a film-forming aid, and an anti-mold and/or anti-algae agent, The anti-mold and/or anti-algae agent is applied with a water-based base conditioner composition in an amount of 0.3 to 1.0 parts by weight based on 100 parts by weight of the composition to form a water-based base conditioner composition layer;
A water-based coating material composition further comprising an acrylic resin emulsion, a filler, an aggregate, a pigment, a thickener, and a film-forming aid, further comprising: A water-based coating composition containing less than 1.0 parts by weight of an algae agent based on 100 parts by weight of the composition, or containing no anti-mold and/or anti-algae agent, is applied at least once to form a water-based coating composition layer. Provided is a coating material finishing method characterized by forming.
本発明の塗材仕上げ構造は、防カビ及び／または防藻性を有するという効果があり、また、本発明の塗材仕上げ構造が形成される壁の周囲にある植栽を枯らすことがない、という効果がある。従来、塗材仕上げ構造の表面にカビや藻が繁殖するのを防ぐために、上塗り材（本発明でいうところの水系塗材組成物）には防カビ性および／または防藻性を発揮するのに十分な量の防カビ及び／または防藻剤が添加されてきた。一方で、このような上塗り材を用いた塗材仕上げ構造の周囲では、植栽が枯れていることが確認される場合があった。本発明者は、このように植栽が枯れるのは上塗り材に含まれる防カビ及び／または防藻剤が、上塗り材層に浸潤した雨水や湿気等の水分に溶解して流出し、植栽に到達することで枯らしているのではないかと想到し、本発明をするに至った。上塗り材である水系塗材組成物に含ませる防カビ及び／または防藻剤の量を制限、または０とし、下塗り材である水系下地調整材組成物に防カビ及び／または防藻剤を含ませることにより、防カビ及び／または防藻剤が雨水等に溶解することを抑制、もしくは無くすことができていると推測している。 The coating material finishing structure of the present invention has the effect of having anti-mold and/or algae-proofing properties, and also does not kill the plants around the wall on which the coating material finishing structure of the present invention is formed. There is an effect. Conventionally, in order to prevent the growth of mold and algae on the surface of a painted structure, top coating materials (water-based coating compositions in the sense of the present invention) have been required to exhibit anti-mold and/or anti-algae properties. Sufficient amounts of antifungal and/or antialgal agents have been added. On the other hand, there have been cases where it has been confirmed that plants have withered around the finished structure using such a top coat material. The present inventor believes that the reason why the plants die is that the antifungal and/or antialgal agent contained in the topcoat material dissolves in water such as rainwater and moisture that has permeated the topcoat layer and flows out, causing the plants to die. We came up with the idea that the plant may be dying when it reaches this point, and came up with the present invention. The amount of the anti-mold and/or anti-algae agent contained in the aqueous coating material composition that is the top coat material is limited or zero, and the amount of the anti-mold and/or anti-algae agent contained in the water-based base conditioner composition that is the undercoat material is limited or zero. It is presumed that by applying this, it is possible to suppress or eliminate the dissolution of the anti-mold and/or anti-algae agent into rainwater, etc.
以下、本発明について詳細に説明する。 The present invention will be explained in detail below.

The water-based base conditioner composition and the anti-mold and/or anti-algae agent constituting the water-based coating composition used in the present invention prevent the growth of mold and algae on the finished structure of the coating material and maintain its aesthetic appearance. It is blended with the purpose of Some anti-mold agents and anti-algae agents have the same ingredients, and these anti-mold and anti-algae agents can provide both anti-mold and anti-algae properties by using only one type of anti-mold agent and anti-algae agent. Alternatively, when using an algaecide, only one kind may be used, or a combination of one having only anti-fungal properties and one having only anti-algae properties may be used. Of course, if only one of anti-fungal properties and anti-algae properties is required, a material having only one of them may be used. Examples of antifungal and/or antialgal agents include 3-(3,4-dichlorophenyl)-1,1-dimethylurea (also known as DCMU, diuron), 2-(methoxycarbonylamino)-1H-benzimidazole (also known as : BCM, carbendazim), 2-n-octyl-4-isothiazolin-3-one (also known as OIT, octylion), and zinc pyrithione. Among them, DCMU has high water solubility, and when included in the finishing structure of the coating material, it is easily dissolved in rainwater or moisture that has permeated the coating material, and is preferred because it exhibits excellent anti-mold and/or anti-algae properties. However, on the other hand, it is thought that the impact on plants will be greater, but it is now possible to use anti-mold and/or anti-algae agents containing such ingredients without worrying about the negative effects on plants. This is what the present invention has accomplished.
防カビ及び／または防藻剤の配合量は、水系下地調整材組成物においては組成物１００重量部中０．３～１．０重量部であることが好ましく、０．３重量部未満では防カビ及び／または防藻性が不十分となる場合があり、１．０重量部超では耐候性が低下し黄変や白化等が生じて塗材仕上げ構造の意匠性が損なわれる場合がある。また、水系塗材組成物においては組成物１００重量部中１．０重量部未満であることが好ましく、より好ましくは０．５重量部以下、更に好ましくは０．０５重量部以下であるとよい。本発明の性質上、植栽影響性の観点から、水系塗材組成物に含まれる防カビ及び／または防藻剤の配合量は少ないほどよいため、水系塗材組成物に防カビ及び／または防藻剤を含ませなくても良い。 The amount of the antifungal and/or antialgal agent in the aqueous base conditioner composition is preferably 0.3 to 1.0 parts by weight per 100 parts by weight of the composition; Mold and/or algae-proofing properties may become insufficient, and if it exceeds 1.0 parts by weight, weather resistance may decrease, causing yellowing, whitening, etc., and the design of the finished structure of the coating material may be impaired. In addition, in a water-based coating composition, the amount is preferably less than 1.0 parts by weight based on 100 parts by weight of the composition, more preferably 0.5 parts by weight or less, still more preferably 0.05 parts by weight or less. . Due to the nature of the present invention, the smaller the amount of the anti-mold and/or algae agent contained in the water-based coating composition, the better from the viewpoint of impact on plants. It is not necessary to include an algaecide.
本発明において防カビ及び／または防藻性が得られるのは、水系下地調整材組成物層に含まれる防カビ及び／または防藻剤が、塗材仕上げに浸潤した雨水や湿気の水分等に溶解し、防カビ及び／または防藻剤の濃度の高い水系下地調整材組成物層から、防カビ及び／または防藻剤の濃度の低い水系塗材組成物層へ移動し、カビ及び／または藻に働きかける、というメカニズムによると推測している。該メカニズムにより、上塗りである水系塗材組成物に含まれる防カビ及び／または防藻剤が、水系塗材組成物単体で防カビ及び／または防藻性が得られる量だけ含まれていなくても、塗材仕上げ構造の表面にカビ及び／または藻が繁殖しないものである。 In the present invention, the anti-mold and/or anti-algae property is obtained because the anti-mold and/or anti-algae agent contained in the aqueous base conditioner composition layer absorbs moisture from rainwater or moisture that has permeated the coating material finish. It dissolves and moves from the water-based base conditioner composition layer with a high concentration of mold and/or anti-algae agents to the water-based coating material composition layer with a low concentration of mold and/or anti-algae agents, and mold and/or We speculate that the mechanism is that it acts on algae. Due to this mechanism, the anti-mold and/or anti-algae agent contained in the water-based coating composition that is the top coat is not contained in an amount sufficient to provide anti-mold and/or anti-algae properties in the water-based coating composition alone. Also, mold and/or algae will not grow on the surface of the painted structure.

It is preferable that the metal trowel is made of stainless steel with a thickness of 0.3 to 0.7 mm because it allows for easy application. Since the spray gun for architectural coating materials changes the size of the particles of the sprayed composition depending on the aperture size, and the resulting design also changes, the aperture size suitable for forming the desired design is appropriately selected. In addition, water may be added to the water-based base conditioner composition and the water-based coating material composition to the extent that it does not affect the results of the evaluation tests below so that the viscosity is suitable for application with each construction tool. can.
