[0045] 1. Manufacture of water-based paint for wallpaper

[0046] Polyoxyethylene alkyl ether (HLB=10.5, hereinafter referred to as "POE alkyl ether") was dissolved in water with a stirrer in a 1-liter stainless steel container. Further, titanium dioxide shown below was added and mixed for 30 minutes, and then an emulsion of a reactive polysiloxane compound and an aqueous polyvinyl alcohol solution were added and mixed for 30 minutes. Finally, after adjusting the viscosity to 4000-5000 mPa·s with a non-ionic thickener (trade name: Neostetsuka-N Nichika Chemical Co., Ltd.), a water-based paint for wallpaper was produced.

[0047] Specifically, the following components were used. In addition, the compounding ratio (weight part) of each component is as shown in Tables 1-3.

[0048] (1) Titanium dioxide

[0049] Titanium dioxide A: monoclinic fibrous titanium dioxide (trade name: MTW-500, manufactured by Otsuka Chemical, average fiber diameter 0.3 μm, average fiber length 10 μm...

Abstract

A water-based coating composition for wallpapers which comprises fibrous monoclinic titanium dioxide, a reactive silicone compound, and polyvinyl alcohol as effective ingredients; and a wallpaper having a coating layer formed from the water-based coating composition. The wallpaper is excellent not only in the function of protecting interior members or in deodorizing or antibacterial performance but in decorative properties, whiteness, texture, and appearance.

Description

technical field [0001] The invention relates to a water-based paint for wallpaper and the wallpaper. Background technique [0002] With the remarkable improvement of housing environment equipment and the enactment of the Law for the Promotion of Housing Quality Securing, there is a strong demand for longer life of buildings and longer life of interior components. In particular, in recent residential models, it is difficult to maintain the quality and maintenance of the original construction quality and maintenance of the wallpaper in the large space of the living room and dining room connected to the ventilation space from the entrance part. [0003] In order to protect the interior components of the building, a kind of wallpaper that is designed to form a coating layer containing a photocatalyst coating such as titanium dioxide is proposed. Such wallpaper not only protects interior components and contributes to a longer life, but also exhibits antibacterial and deodorizing...
