A kind of preparation method of moistureproof water-based crackle wallpaper
Technical field
The present invention relates to adornment technical field, be specifically related to a kind of preparation method of moistureproof water-based crackle wallpaper.
Background technology
Wallpaper, also referred to as wallpaper, wall paper, being a kind of indoor hardware fitting for papering metope, being widely used in the interior decoration etc. in house, office, hotel, hotel.Material is not limited to paper, also comprises other materials.
Because have the advantages that other house decorative materials multiple such as color is various, pattern enriches, luxurious style, safety and environmental protection, easy construction, affordable are incomparable, therefore obtain the universal of certain degree at the developed countries and regions such as American-European, Japanese.
Wallpaper is divided into a lot of class, as overlay film wallpaper, coating wallpaper, embossing wallpaper etc.Usually produce body paper with bleached wood pulp, then through the processing process of different operation, cover as coating, printing, embossing or surface and mould, dispatch from the factory after cutting, packing.There is certain intensity, toughness, appearance attractive in appearance and good water repelling property.
Wallpaper is the important component part of Modern Interior Decoration material, is one of indoor wall surface primary decoration finishing material, because wallpaper has good decorative effect, so obtain applying more and more widely.Along with improving constantly of socioeconomic development and people's level of production, hotel and house emerge in multitude, and people require more and more higher to the fitting-up of indoor, more focus on the decorative effect of surface of wall.At present, increasing people is devoted to the research of wallpaper, but research stays in the decorative effect aspect of wallpaper mostly, as changed the aspects such as pattern, more focuses on surface.And after wallpaper more applies and be Indoor environment finishing, occupy indoor very large area, if it can have some function, as antibacterial functions, then can play good effect.And the wallpaper of prior art does not all possess antibacterial functions.Prior art more focuses on the fancy design on surface, the collocation of color and the decorative effect of entirety, few to the functional emphasis of wallpaper, especially to the antibiotic property of wallpaper, the research of health application function is not enough, can not meet consumers in general to the requirement of wallpaper with antibacterial functions.In order to adapt to the needs of special space environment, the place that as crowded in hospital, school etc. and bacterium is easily propagated, the wallpaper as decorative material for internal wall should have antibacterial function.Therefore, people urgently wish that a kind of antibacterial wallpaper and preparation method thereof is come out.
