Abstract
Description
本発明は、新規な表面処理材に関するものである。 The present invention relates to a novel surface treatment material.
従来、建築物の仕上げとしては、建築物の床、壁、天井、柱、梁等を構成する主な材料であるコンクリート、モルタル、ＡＬＣ、ＰＣ、珪酸カルシウム板、プラスター等の無機質基材、あるいは断熱材としてのスチレンフォーム板、ウレタンフォーム板等の有機質材料を下地材とし、これに仕上塗材、陶磁器タイル、壁紙等の仕上材が施工されている。このような下地材は、一般に、不陸、巣穴、欠損部等の凹凸を有することが多く、そのままでは美観性を損なうため、表面処理材を用いて下地の平滑化や欠陥部位の補修が行われている。 Conventionally, as a finish of a building, an inorganic base material such as concrete, mortar, ALC, PC, calcium silicate board, plaster, etc., which is the main material constituting the floor, wall, ceiling, pillar, beam, etc. of the building, or An organic material such as a styrene foam board or a urethane foam board as a heat insulating material is used as a base material, and a finishing material such as a finish coating material, ceramic tile, or wallpaper is applied thereto. Such a base material generally has irregularities such as unevenness, burrows, and defects, and the aesthetics are impaired as it is, so surface treatment materials can be used to smooth the base and repair defective areas. Has been done.
このような表面処理材としては、セメントに合成樹脂を配合したものが多く使用されており、例えば、特許文献１には、セメントに平均粒子径が０．３〜０．８μｍのエチレン酢酸ビニル樹脂エマルションを配合したセメント組成物が記載されている。しかし、特許文献１のようにセメントに、単に合成樹脂エマルションを配合しただけでは、養生温度等の条件によっては下地材との付着性が不十分となるおそれがある。これに対して、特許文献２には、異なるガラス転移温度を有する粉末ポリマーを２種類以上配合したセメント組成物が記載されており付着性を改善できることが記載されている。 As such a surface treatment material, a material in which a synthetic resin is blended with cement is often used. For example, Patent Document 1 discloses an ethylene vinyl acetate resin having an average particle diameter of 0.3 to 0.8 μm in cement. A cement composition incorporating an emulsion is described. However, if the synthetic resin emulsion is simply added to the cement as in Patent Document 1, the adhesion to the base material may be insufficient depending on conditions such as the curing temperature. On the other hand, Patent Document 2 describes a cement composition in which two or more kinds of powder polymers having different glass transition temperatures are blended, and describes that adhesion can be improved.
しかし、特許文献２のように粉末ポリマーを２種以上併用した場合であっても、十分な付着強度が得られない場合があり、特に耐久性が不十分となるおそれがあった。 However, even when two or more powder polymers are used in combination as in Patent Document 2, sufficient adhesion strength may not be obtained, and durability may be insufficient.
本発明は、上述のような問題点に鑑みなされたもので、優れた付着性及び耐久性を有する表面処理材を得ることを目的とするものである。 The present invention has been made in view of the above problems, and an object thereof is to obtain a surface treatment material having excellent adhesion and durability.
