Probably the most concerned problems for consumers whenever choosing decorative components, especially soft materials that are intimately in touch with the body, is environmental safety. The most commonly used coatings for wall structure decoration, actually, mostly contain toxins. Therefore, when more customers in China decorate new houses, they would rather choose wallpapers instead of paints. What are the specific advantages of wallpapers with regards to environmental protection in accordance with coatings? ? And see the following to know!
First, the composition of wallpaper and paint comparison
1, the main elements of the wallpaper
The wallpaper is principally composed of base paper, ink and accessories. There are three main types of foundation paper: wallpaper bottom paper (paper foundation and pure paper), non-woven fabric, and underneath paper is generally obtained from natural plant fibers such as for example wood, cotton, and hemp.
Wallpaper accessories could be easily split into rubber powder, wet glue and foundation film. Rubber powder and wet glue are modified starch prepared from potato and corn, which may be degraded in character. The main component of the wet glue is hydroxypropyl distarch phosphate, which is a thickener in yoghurt, and the primary component of the base film is an emulsion of styrene and acrylate polymerized in water, namely styrene-acrylic emulsion, which is very green. An intermediate chemical.
2, the main elements of the paint
Coatings (also called latex paints) are mainly composed of four parts: foundation materials, pigment, filler and auxiliary agent. The primary component of the base material is a styrene-acrylic emulsion; the inorganic pigment element includes oxides and salts of metals such as carbon dark, iron, zinc, chromium, cadmium and titanium, and the organic pigment is divided into azo pigments, lakes, copper titanium Classes, fused bands and organic macromolecular pigments; fillers mainly include titanium dioxide, kaolin, wollastonite, heavy calcium, light calcium and other powders; and additives primarily include wetting brokers, dispersants, defoamers, Thickener bactericidal fungicide, whitening agent, etc.
Evaluation of wallpaper and color composition Conclusion:
The chemical composition of the paint is quite complex, and the recycleables for the wallpaper are mostly from plants. All wallpaper factories have drying processes and plasticizer cooling recovery devices in the production procedure. VOCs are dried and recycled before departing the factory. When the color is used, it is still a liquid, and the volatile matter is volatilized at the use site–home, which harms consumers, therefore the wallpaper is more environmentally friendly.
Second, the impact on health
1. The paint is seriously dangerous, and the national heavy tax control
In early 2015, the state made a decision to impose a 4% consumption tax on color. In 10 provinces such as Shanghai and Jiangsu, officially issued a VOC (carcinogenic volatile matter) sewage costs, it has been proved that the color has real damage to the atmospheric environment and human being health.
2, carcinogen VOC and APEO!
VOC identifies volatile organic compounds, which are the way to obtain environmental pollution, damage the brain and nervous system, and are also important factors in the forming of smog. The national mandatory standard has a Original Wallpapers optimum VOC limit of 120 g/L for water-based interior wall coatings, but VOC will volatilize indoors during structure and drying. In 2014, the Shanghai Quality Supervision Bureau conducted quality inspections on the circulating wallpapers in the marketplace. The content of VOCs in the wallpapers had not been more than 10 mg/kg. In short, the VOC content material of latex paints is nearly 12,000 occasions that of wallpapers!
APEO is an abbreviation for alkylphenol ethoxylates and is a trusted non-ionic surfactant. APEO is challenging to degrade and has carcinogenic and female effects on the human body. The two main indicators for screening the spotted coating items are VOC and APEO. Therefore, compared with the imported high-end environmentally friendly wallpaper with high protection, the coating is harmful to human body on carcinogens. Big.
3. The harm of formaldehyde!
The general coating contains formaldehyde and has a strong irritating taste. Therefore, the paint construction expert must wear a mask to avoid inhalation of extreme formaldehyde and poison; while the general wallpaper construction master does not need to wear a mask to carry out the work 
of posting wallpaper, specifically imported high-end wallpaper. With world-class RAL quality certification, formaldehyde is not detected, and the testing standard is 30 times stricter compared to the national standard!
