Description
本発明は、新規な装飾性塗材及び装飾性建材に関するものである。 The present invention relates to a novel decorative coating material and decorative building material.
従来、建築物や土木構造物等の表面化粧材として、結合剤に着色骨材等を配合した各種装飾性塗材が提案されている。一例として、特開平11−130980号公報(特許文献1)には、0.05〜5mmの粒径を有する骨材100重量部に対して、合成樹脂エマルションを固形分換算で5〜20重量部含有する組成物が記載されている。特許文献1の塗材では、天然石調等の仕上外観を得ることができる。
これに対し、最近では、比較的小さな粒径の着色骨材を配合した塗材が提案されている。例えば、特開2001−3002号公報(特許文献2)には、着色骨材として平均粒径10〜150μmのものを使用した塗材が記載されている。特許文献2においては、比較的粒径の小さな着色骨材を採用することで、微細な粒が点在した、旧来の砂壁調の多彩な仕上外観が得られることが記載されている。
Conventionally, various decorative coating materials in which a colored aggregate or the like is blended into a binder have been proposed as surface decorative materials for buildings, civil engineering structures, and the like. As an example, Japanese Patent Laid-Open No. 11-130980 (Patent Document 1) discloses that a synthetic resin emulsion is 5 to 20 parts by weight in terms of solid content with respect to 100 parts by weight of an aggregate having a particle size of 0.05 to 5 mm. The containing composition is described. With the coating material of Patent Document 1, a finished appearance such as natural stone tone can be obtained.
On the other hand, recently, a coating material containing a colored aggregate having a relatively small particle diameter has been proposed. For example, JP 2001-3002 A (Patent Document 2) describes a coating material using a colored aggregate having an average particle size of 10 to 150 μm. Patent Document 2 describes that by adopting a colored aggregate having a relatively small particle size, various finished appearances of an old sand wall tone, in which fine particles are scattered, are described.
しかしながら、上記特許文献2のように、単に着色骨材の粒径を小さくするだけでは、塗膜形成段階ないし塗膜形成後において、塗膜に割れが生じやすくなるという問題が生じる。また特許文献2の塗材によれば、大粒径の着色骨材では得られ難い多彩感が表出できるものの、その意匠は人工的なものになりやすいという傾向もある。 However, as described in Patent Document 2, simply reducing the particle size of the colored aggregate causes a problem that the coating film is likely to be cracked during the coating film formation stage or after the coating film formation. Further, according to the coating material of Patent Document 2, although it is possible to express a variety of feelings that are difficult to obtain with colored aggregates having a large particle size, the design tends to be artificial.
本発明は上述のような問題点に鑑みなされたものであり、本発明における第1の課題は、形成塗膜の割れ発生を抑制することができる装飾性塗材を得ることである。第2の課題は、微妙に色合いが変化する自然な多彩感が表出可能な装飾性塗材を得ることである。さらには、このような装飾性塗材をシート状に成形して、同様の効果を奏する装飾性建材を得ることである。 This invention is made | formed in view of the above problems, and the 1st subject in this invention is obtaining the decorative coating material which can suppress generation | occurrence | production of the crack of a formed coating film. The second problem is to obtain a decorative coating material capable of expressing a natural variety with a subtle change in hue.

By having such a relative relationship between the component (B) and the component (D), it is possible to suppress the occurrence of worm-eaten streaks and the like when applying a trowel and form a flat and uniform coating film. it can. That is, a coating material suitable for iron coating can be obtained. In particular, when the average thickness of the component (D) is larger than the particle diameter of the maximum particle of the component (B), such an effect is easily obtained stably.
