Description

本発明は、建築物用塗料組成物に関するものである。本発明塗料組成物は、特に、建築物の内装仕上げ用塗料として好適に使用することができる。   The present invention relates to a building paint composition. The paint composition of the present invention can be suitably used particularly as a paint for interior finishing of buildings.

近年、建築物の室内環境においては、結露によるカビの発生、揮発性有機化合物によるシックハウス等が社会的な問題として取り上げられている。
これに対し、室内環境向上効果を狙った種々の塗料組成物や塗装工法が提案されている。
例えば、特開昭61−141967号公報(特許文献1)には、壁面の結露に起因する腐食やカビ発生等を防止するために、透湿性を有する塗膜を形成する手法が開示されている。
特開昭62−74966号公報(特許文献2)には、室内における湿度変動を緩和する機能を有する調湿性塗料が開示されている。特許文献2に記載の塗料は、合成樹脂エマルション、珪藻土、吸水性ポリマー等を主成分とし、顔料容積濃度を55%以上に調製したものである。
特開2002−138252号公報(特許文献3)には、結露防止、カビ予防、脱臭、化学物質の除去作用等の効果が得られる塗料として、焼成珪藻土粉末、樹脂エマルション、及び天然植物精油を含むものが開示されている。
また、特開2000−169757号公報(特許文献4)には、シックハウスの原因物質であるアセトアルデヒドやホルムアルデヒド等の吸着分解能を有する塗料組成物が開示されている。特許文献4の塗料組成物は、骨材、接着剤、及びアルデヒド化学吸着剤を構成成分とするものである。
以上に例示したような塗料では、透湿性、吸放湿性(調湿性)、化学物質吸着性等において十分な性能を得るために、いずれも顔料容積濃度が高く設定されている。すなわち、多量の粉体成分によって形成塗膜をポーラスな状態にせしめ、水分や化学物質が塗膜内部にまで到達できるように設計されている。
In recent years, in the indoor environment of buildings, generation of mold due to dew condensation, sick house due to volatile organic compounds, and the like have been taken up as social problems.
On the other hand, various coating compositions and coating methods aimed at improving the indoor environment have been proposed.
For example, Japanese Patent Application Laid-Open No. 61-141967 (Patent Document 1) discloses a method of forming a moisture-permeable coating film in order to prevent corrosion, mold generation, and the like due to condensation on the wall surface. .
Japanese Laid-Open Patent Publication No. 62-74966 (Patent Document 2) discloses a humidity control paint having a function of reducing humidity fluctuations in a room. The paint described in Patent Document 2 has a synthetic resin emulsion, diatomaceous earth, a water-absorbing polymer, and the like as main components and a pigment volume concentration adjusted to 55% or more.
JP-A-2002-138252 (Patent Document 3) includes calcined diatomaceous earth powder, resin emulsion, and natural plant essential oil as paints that provide effects such as condensation prevention, mold prevention, deodorization, and removal of chemical substances. Are disclosed.
JP-A-2000-169757 (Patent Document 4) discloses a coating composition having an adsorption ability such as acetaldehyde or formaldehyde which is a causative substance of sick house. The coating composition of patent document 4 uses an aggregate, an adhesive agent, and an aldehyde chemical adsorption agent as a structural component.
In the paints as exemplified above, the pigment volume concentration is set high in order to obtain sufficient performance in moisture permeability, moisture absorption / release properties (humidity control), chemical substance adsorption, and the like. In other words, the coating film is designed to be made porous by a large amount of powder components so that moisture and chemical substances can reach the inside of the coating film.

特開昭61−141967号公報JP 61-141967 A 特開昭62−74966号公報JP-A-62-74966 特開2002−138252号公報JP 2002-138252 A 特開2000−169757号公報JP 2000-169757 A

上述の如き塗料において顔料容積濃度を高くすることは、透湿性、吸放湿性、化学物質吸着性等の性能向上には有効な手段である。しかし、その反面、実用上の問題が生じる。
第一には、汚れが一旦付着してしまうと除去し難くなるという問題である。建築物内装面において、手垢等の汚れが付着するのは日常的であるが、その汚れが拭き取り可能であれば、本来の美観性を取り戻すことができる。ところが、顔料容積濃度を高く設定した塗料では、手垢等の汚れ成分が塗膜の微細な凹凸部分に入り込んでしまい、拭き取りが困難な状態に陥りやすくなる。
第二には、形成塗膜における割れ発生の問題である。顔料容積濃度を高くすれば、相対的に結合剤の比率が低下するため、塗膜に割れが生じやすくなる。特に、厚膜タイプの塗料においては、塗装条件や塗装環境の変動が塗膜形成に大きく影響する場合があり、塗膜割れの問題も生じやすくなる。
Increasing the pigment volume concentration in the paint as described above is an effective means for improving performance such as moisture permeability, moisture absorption / release properties, and chemical substance adsorption. However, practical problems arise.
The first problem is that once the dirt adheres, it becomes difficult to remove. On the interior surface of a building, dirt such as hand dust is daily, but if the dirt can be wiped off, the original aesthetics can be restored. However, in a paint having a high pigment volume concentration, dirt components such as hand stains enter the fine uneven portions of the coating film, and it is easy to fall into a state where wiping is difficult.
The second problem is the occurrence of cracks in the formed coating film. When the pigment volume concentration is increased, the ratio of the binder is relatively decreased, and thus the coating film is easily cracked. In particular, in a thick film type coating material, variations in coating conditions and coating environment may greatly affect the formation of the coating film, and the problem of coating film cracking is likely to occur.

本発明は、上記問題点に鑑みなされたものであり、透湿性、吸放湿性、化学物質吸着性等の機能性を有する塗料において、汚れ除去性、割れ防止性を改善することを目的とする。   The present invention has been made in view of the above problems, and an object thereof is to improve soil removability and crack prevention in a paint having functionality such as moisture permeability, moisture absorption / release properties, and chemical substance adsorptivity. .
