Description
本発明は、特にガラス素材の表面に複数の孔を形成されることにより、ガラスの親水性を向上するすると共に、ガラスの透過性や反射性に影響を与えないガラス素材の親水表面を製作する化学処理剤及び方法に関するものである。 In particular, the present invention improves the hydrophilicity of the glass by forming a plurality of holes on the surface of the glass material, and produces a hydrophilic surface of the glass material that does not affect the permeability and reflectivity of the glass. The present invention relates to chemical processing agents and methods.
ガラス素材に曇り防止の効果を有する親水化学物は、例えばＰＶＡ、ＰＶＭＥ、界面活性剤及び半導体光触媒などを有し、該親水化学物をガラスや鏡に塗布した後、曇り防止の効果を有する親水フイルムが形成される。水滴が該親水フィルムに付着すると、直ちに親水フィルムに分散されることにより、ガラス素材の優れる透過度を維持するが、該親水フィルムは耐久性や耐損耗性が悪いと言う欠点を有する。
前記親水フィルムの製作方法において、主にスプレー法、浸漬法、塗布法及び気体メッキ法を有し、該浸漬法と塗布法と気体メッキ法が製品の製造過程中で行う方法であるため、一般の使用者に適用できず、スプレー法がよく使用される一般の方法である。又、前記スプレー法、浸漬法、塗布法及び気体メッキ法は一般によく使用される方法であることから、特に特許文献又は非特許文献には記載されていない。
Hydrophilic chemicals that have an anti-fogging effect on glass materials include, for example, PVA, PVME, surfactants, semiconductor photocatalysts, etc., and the hydrophilic chemicals have an anti-fogging effect after being applied to glass or mirrors. A film is formed. When water droplets adhere to the hydrophilic film, they are immediately dispersed in the hydrophilic film, thereby maintaining the excellent transparency of the glass material. However, the hydrophilic film has a drawback of poor durability and wear resistance.
The hydrophilic film production method mainly includes a spray method, a dipping method, a coating method, and a gas plating method, and the dipping method, the coating method, and the gas plating method are performed in the manufacturing process of the product. The spray method is a general method that cannot be applied to the user. Moreover, since the spray method, the dipping method, the coating method, and the gas plating method are generally used methods, they are not particularly described in patent documents or non-patent documents.
しかしながら、上記スプレー法は使用者によって以下に示すように不便な欠点を有する。 However, the spray method has inconvenient disadvantages as shown below depending on the user.
１、 被塗布物の表面における汚れを先に中性の界面活性剤又はアルコール類の洗剤により完全に除去する必要があるので、非常に面倒である。 1. It is very troublesome because dirt on the surface of an object to be coated must first be completely removed by a neutral surfactant or an alcohol detergent.
２、 コンプレッサーとスプレー器具を使用し、適当な距離によって均一にスプレーを行うことができるので、非常に面倒である。 2. Using a compressor and a spray device and spraying uniformly at an appropriate distance is very troublesome.
３、
数回繰返してスプレーを行う必要があるので、非常に面倒である。
又、親水フィルムの主な問題はやはり耐久性であり、即ち老化問題であり、これは親水フィルムをガラス素材の表面に塗布する化学物であるので、耐久性や耐損耗性が悪いと脱落しやすいと言う欠点を有する。
そこで、出願されたのが本発明であって、ガラス素材の表面に複数の孔を形成されることにより、ガラスの親水性を向上するすると共に、ガラスの透過性や反射性に影響を与えないガラス素材の親水表面を製作する化学処理剤及び方法を提供することを目的としている。
3,
It is very troublesome because it is necessary to spray several times.
Also, the main problem with hydrophilic films is durability, that is, aging problems, which are chemicals that apply hydrophilic films to the surface of glass materials, so if they are not durable or wear-resistant, they will fall off. It has the disadvantage of being easy.
Therefore, the present invention has been filed, and by forming a plurality of holes on the surface of the glass material, the hydrophilicity of the glass is improved and the transparency and reflectivity of the glass are not affected. It aims at providing the chemical processing agent and method which produce the hydrophilic surface of a glass raw material.
