The incident originated from the warning of quality and safety of wallpapers released by the Shanghai Bureau of Quality Supervision. The results of the risk monitoring pointed out that “this risk monitoring collected 58 batches of samples and covered the major brands produced and sold in the city.

After inspection, 53 batches of samples detected plasticizers (DBP, DEHP, BBP), of which 34 batches were above the reference limit of 0.1%; 58 batches of sample plasticizers (DNOP, DINP, DIDP) were not A total of 58 batches of sample volatile organic compounds (TVOCs) were detected, but all were below the reference limit of 10 mg/kg. ”

Subsequently, an article titled “90% of wallpaper was found to contain plasticizers” made the wallpaper industry almost “collectively”.

The article pointed out that "90% of the wallpaper was detected containing plasticizers" "wallpaper contains plasticizers have a certain degree of carcinogenic effect" ... ... in the wallpaper industry caused no small earthquake.

A series of allegations against wallpaper products also made many wallpaper company representatives stand out.

Is it not a time, it is difficult to distinguish. As consumers, more concerned about the outcome of the incident, in the end there is no plasticizer wallpaper? Plasticizer in the end whether it is harmful to the human body? In the end there is no environmental protection wallpaper? ... ... To this end, home network reporter made further survey.

What are the “90%” figures for plasticizers? Baidu's results show that plasticizers are industrially widely used additives for polymer materials. Adding this material to plastic processing can increase its flexibility. , easy to process, can be legally used for industrial purposes.

China Construction Decoration Materials Association wallpaper branch secretary Zhang Xiaohong told reporters that there are three kinds of wallpaper products: PVC, non-woven fabrics and plain paper. Only plasticizers were added to PVC wallpapers, and no plasticizers were found in non-woven wallpapers and plain paper wallpapers. Although PVC wallpaper is classified as building materials, its processing technology belongs to plastic products. Plasticizers are added to increase its elasticity and flexibility.

Zhang Shuhong said that there are three types of wallpapers in China: PVC, non-woven fabrics, and plain paper. Only PVC wallpapers have plasticizers added to their process needs, while PVC wallpapers account for only 40% of the total wallpaper in China. With plasticizers, this argument is untenable.

Wallpaper Association Expert: The lack of professional risk detection The AQSIQ conducted a risk assessment on wallpaper in 2013. Zhang Shuhong as an expert participant said: “The purpose of risk assessment is to assist the industry to develop better than to injure the industry. ."

Zhang Yuhong stated that the monitoring of the safety risks conducted by the Shanghai Bureau of Quality Supervision had not been confirmed by the authoritative department of the State Administration of Quality Supervision, and it had no legal effect. At most, it only served to warn the industry.

In addition, industry experts said that the two standards that the Shanghai Quality Supervision Bureau carried out for the risk detection were: GB/T 21928-2008 Determination of Phthalates in Food Plastic Packaging Materials, GB 6675.1- In 2014, “Toy Safety Part 1: Basic Regulations”, the detection of wallpaper products based on the two standards of the food industry and toy industry is inconsistent with the detection method and does not possess the testing expertise. Although cross-border is now popular, it is not rigorous or desirable to use other industry or product standards when testing products.

Wallpaper industry due to plasticizers

It is understood that as many as 100 kinds of plasticizers, plasticizers have been added in many daily products, such as all plastic products, medical equipment, cling film, perfume, nail polish and so on.

This event focused on phthalate ester plasticizers such as DBP, DEHP, BBP, DNOP, DINP, and DIDP.

Related data shows that phthalate plasticizers can be subdivided into low molecular weight and high molecular weight according to their molecular weight. Low phthalate plasticizers mainly refer to phthalate esters with 3 to 6 carbon atoms in the main chain of the chemical backbone. Commonly known are DEHP, DBP, DIBP and BBP, and high phthalates. It mainly refers to phthalate esters with 7 to 13 carbon atoms in the backbone of the chemical backbone. The common ones are DINP and DPHP.

The plasticizer reporter also asked relevant experts from the National Center for Disease Control.

Decoration Network experts, plasticizers are internationally long-term controversial topic, in the EU REACH Act, DEHP, DBP and BBP three low phthalate ester plasticizers are listed as highly concerned substances. The EU recommends importing products and not importing products. On December 27, 2005, the new directive 2005/84/EC issued by the European Union required that the content of DEHP, DBP and BBP (low phthalate plasticizers) in all toys and childcare articles should not exceed 0.1%. Otherwise, it must not be sold in the EU market.

All toys and parenting items that can be placed in the child's mouth, the content of DINP, DIDP and DNOP (high phthalate plasticizer) shall not exceed 0.1%. In China, the Ministry of Health announced in June 2011 that the maximum residues of DEHP, DINP, and DBP in food and food additives were 1.5 mg/kg, 9.0 mg/kg, and 0.3 mg/kg, respectively. In terms of toy products, the limitation of plasticizers is equivalent to the current EU regulations.

Some experts pointed out that regarding the application of phthalate ester plasticizers, the method of limiting “bottom” pushing “high” can be used as a reference.

For the network, "wallpaper contains plasticizers have a certain carcinogenic effect." According to experts from the National Center for Disease Control, “Although plasticizers still have many controversies, they say that 'wallpapers containing plasticizers have a certain carcinogenic effect', undoubtedly letting wallpapers back their 'black pans', and plasticizers are not volatile at room temperature. It is not easy to migrate and has strong stability. Only the entrance can be teratogenic and mutagenic."

Wallpaper can be truly environmentally friendly According to the renovation network experts, so far, China's wallpaper industry has two current standards, GB18585-2001 "indoor decoration materials wallpaper harmful substances limit" and HJ2502-2010 "environmental label products technical requirements wallpaper."

GB18585-2001 "The limit of harmful substances in indoor decoration materials wallpaper" does not mention plasticizers. HJ2502-2010 "Technical Requirements Wallpaper for Environmental Labeling Products" mentions that it is not allowed to artificially add DEHP, DBP and BBP during the production process.

The former is a national mandatory standard, and the latter is a ministerial standard. There is no mandatory requirement, but many large-scale wallpaper manufacturers in the industry strictly comply with these two standards. Three types of increase in DEHP, DBP and BBP will not be added to the wallpaper production process. Plasticizer.

Is the wallpaper really green or just a gimmick?

Zhang Shuhong said that so far, both meet the GB18585-2001 "indoor decoration materials wallpaper harmful substances limit" and HJ2502-2010 "environmental signs product technical requirements wallpaper" two standard wallpaper is environmental protection wallpaper. In addition, the Green Ten Ring logo is the highest level of environmental certification in China. When consumers purchase wallpaper, they can refer to whether the product has passed the Green Ten Ring logo certification.
