One of the most concerned issues for consumers whenever choosing decorative components, especially soft components that are intimately in contact with the body, is environmental safety. The most commonly used coatings for wall structure decoration, in fact, mostly contain toxins. Therefore, when more customers in China decorate new houses, they would rather choose wallpapers rather than paints. What are the specific advantages of wallpapers with regards to environmental protection in accordance with coatings? ? And start to see the following to know!
First, the composition of wallpaper and paint comparison
1, the main components of the wallpaper
The wallpaper is mainly composed of base paper, ink and accessories. There are three primary types of foundation paper: wallpaper bottom paper (paper bottom and pure paper), non-woven fabric, and the bottom paper is generally obtained from natural plant fibers such as wood, natural cotton, and hemp.
Wallpaper accessories can be easily Classic Wallpaper divided into rubber powder, wet glue and base film. Rubber powder and wet glue are altered starch prepared from potato and corn, which can be degraded in nature. The main element of the wet glue is certainly hydroxypropyl distarch phosphate, which really is a thickener in yoghurt, and the primary component of the base film can be an emulsion of styrene and acrylate polymerized in drinking water, namely styrene-acrylic emulsion, which is quite green. An intermediate chemical.
2, the main components of the paint
Coatings (also known as latex paints) are mainly made up of four parts: bottom material, pigment, filler and auxiliary agent. The primary component of the bottom material is a styrene-acrylic emulsion; the inorganic pigment element contains oxides and salts of metals such as for example carbon dark, iron, zinc, chromium, cadmium and titanium, and the organic pigment is split into azo pigments, lakes, copper titanium Classes, fused bands and organic macromolecular pigments; fillers mainly include titanium dioxide, kaolin, wollastonite, weighty calcium, light calcium and other powders; and additives mainly include wetting agents, dispersants, defoamers, Thickener bactericidal fungicide, whitening agent, etc.
Assessment 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 gadgets in the production procedure. VOCs are dried and recycled before departing the factory. When the color is used, it really is still a liquid, and the volatile matter can be volatilized at the utilization site–home, which harms customers, so the wallpaper is even more environmentally friendly.
Second, the impact on health
1. The paint is seriously dangerous, and the national large tax control
In early 2015, the state decided to impose a 4% consumption tax on color. In 10 provinces such as Shanghai and Jiangsu, officially released a VOC (carcinogenic volatile matter) sewage charges, it has been proved that the color has real damage to the atmospheric environment and individual health.
2, carcinogen VOC and APEO!
VOC identifies volatile organic substances, which are the way to obtain environmental pollution, damage the mind and nervous program, and are also important factors in the forming of smog. The national mandatory standard includes a optimum VOC limit of 120 g/L for water-based interior wall structure coatings, but VOC will volatilize indoors during structure and drying. In 2014, the Shanghai Quality Supervision Bureau carried out quality inspections on the circulating wallpapers out there. The content of VOCs in the wallpapers was not a lot more than 10 mg/kg. In a nutshell, the VOC content of latex paints is almost 12,000 occasions that of wallpapers!
APEO can be an abbreviation for alkylphenol ethoxylates and is a trusted non-ionic surfactant. APEO is challenging to degrade and provides carcinogenic and feminine effects on the body. The two primary indicators for testing the spotted coating items are VOC and APEO. Therefore, weighed against the imported high-end green wallpaper with high protection, the coating is bad for body on carcinogens. Big.
3. The harm of formaldehyde!
The overall coating contains formaldehyde and has a strong irritating taste. Therefore, the paint construction get better at must put on a mask to prevent inhalation of extreme formaldehyde and poison; as the general wallpaper structure master does not need to use a mask to handle the task of posting wallpaper, specifically imported high-end wallpaper. With world-class RAL quality certification, formaldehyde is not detected, and the screening standard is 30 times stricter than the national standard!
