Is the glutinous rice glue used for wallpapering really environmentally friendly?

Many people know that paint has pollution, which contains benzene, formaldehyde, TVOC, and other harmful substances, so they will choose more environmentally friendly and healthy wallpaper when decorating. From the analysis of materials, the wallpaper materials mainly include wood fiber, pure paper, non-woven fabric, resin, cotton, and linen. Including natural materials, as long as it is a qualified wallpaper, the pollution of the material itself is relatively small.

In fact, the choice of accessories is more important than wallpaper! The environmental protection problem of wallpaper is caused by auxiliary materials, including wallpaper glue and base film.

The base film is a hard protective film between the wallpaper and the wall. It cures and protects the surface of the putty, which is convenient for the pasting of the wallpaper and the construction of the secondary wallpaper. The base film cannot be replaced by a varnish in the environmental protection decoration. The base film has no pungent odor. The traditional varnish has a strong pungent odor and slow emission. Glue is the biggest problem causing wallpaper pollution. Wallpaper construction requires a large amount of glue to be applied to the wall. If it contains harmful substances such as formaldehyde, it is not easy to volatilize, and it will cause harm to the human body for a long time. Even if you choose a qualified and safe wallpaper, if the glue is not qualified, it is also easy to cause decoration pollution. Therefore, after choosing to buy wallpaper, glue is also an object that needs to be considered. Don't be careless!

Currently, there are four main types of wallpaper glue on the market:

1. Rubber powder + glue, in which the glue powder is mainly potato starch, and the glue is mainly white glue or transparent glue. When using, you need to pour the rubber powder into the water and adjust it, and then add the glue to enhance the viscosity.

It is recommended to use white glue as the glue. One of the raw materials of transparent glue is formaldehyde. At present, this type of combined glue is used the most in engineering, and environmental problems are likely to occur in the glue. In order to make money, some black-hearted businesses often use inferior transparent glue rich in formaldehyde instead of white glue. Therefore, when purchasing, you can smell the smell and ask for a test report from the merchant to ensure that the formaldehyde does not exceed the standard.

2. Wet glue is mainly made of glutinous rice starch, corn or wheat starch, etc. When using this glue, it only needs to be directly diluted with water, which is relatively environmentally friendly. In China, glutinous rice glue is a trend in home improvement, and it is a kind of high-performance glue for wallpaper. However, some small businesses will incorporate substandard chemical synthetic glue into it to strengthen the bonding force of glutinous rice glue.

3. Glue-free powder, the main raw material is modified potato starch or plant fiber, no need to add glue to use. This type of wallpaper has higher adhesiveness, but the environmental protection performance of glue-free powder on the market is not as good as wet glue for glutinous rice.

4. The finished glue in the barrel, the main component is also white glue-starch, and the glue is directly loaded in the barrel, but it is not as simple as a box of glue powder and a box of glue in the first wallpaper glue. Most of these glues are imported glues, which are very expensive but have good environmental performance and high-cost performance.

From the perspective of the entire home improvement market, glutinous rice glue has become the first choice for decoration due to its high cost-effectiveness, and glue powder + glue sets are often used for engineering wallpaper paving.
