Lead-free paint globally bans water-based paint to add points

The problem of lead in paint has always been a topic in the paint industry. Lead in paint has serious harm to the human body, especially children and pregnant women. Peter Gill Ruth, head of the United Nations Environment Programme’s Department of Early Warning and Assessment, once said at the report’s press conference: “Pb pollution is emerging environmental pollution, and lead paint can cause harm to the health of pregnant women and children.” Gil Ruth called for legislation The department has stepped up its efforts to ensure that it no longer produces lead-containing paints, and calls on the public to pay attention to the harm caused by lead paints to the environment and health. Lead-containing paint hazards

In recent years, there have been several incidents of lead paint poisoning in China. For example, in August 2005, Liu Laohan, a 65-year-old man from Hunan Xinshao, suffered abdominal pain and abnormal stools. He later went to the Shaoyang City Center for Disease Control and Healing for medical treatment. Acute lead poisoning. From 2001 to 2002, Ganluo County had 12 patients with acute lead poisoning, 40 patients with chronic lead poisoning, and 6 patients with silicosis.

Recently, major media have reported on the resolutions of paint companies supporting the United Nations Industrial Development Organization’s initiative to eliminate lead paint, and the country’s decision to gradually phase out lead paint in the next few years. In recent years, while paint companies have continued to increase their market share, they have neglected the issue of lead in paint products. Paints and pigments have always been concerned about lead, especially some of the old paint pigments containing high lead, has caused many deaths, so some countries have specifically formulated environmental standards that the lead content in pigments should be controlled within 600PPM .

On April 22, 2010, the United States began implementing the new leaded paint rules ("Refurbishment, Renovation, and Painting Rules"). According to the Baltimore Sun, the rule applies to renovations, alterations, and paintings of homes built before 1978, while contractors with lead treatment certification must be hired. The new federal rule aims to reduce lead exposure to reduce child poisoning incidents. On December 17, 2013, according to foreign media reports, several paint companies, including Sherwin-Williams, were sentenced Monday to pay $1.1 billion to 10 California counties to clear millions of old houses. Lead paint.

The Globalization of Lead-containing Coatings Prohibits the Future of the Coatings Industry

At present, most of the domestic pigment products contain lead, and now there are many domestic companies that produce pigment products containing lead. Pigments are the main raw materials for coatings, and coating products are also unavoidably lead-containing. So, in the context of the country's call for not using lead paint, how can the future of paint companies and raw material companies go?

Moreover, the country has recently introduced a paint consumption tax. The average profit of the paint industry around 10 will be difficult to guarantee. It will be difficult to survive in the future. In this case, backward paint companies must accelerate their industrial adjustments, otherwise they will be eliminated automatically. . Moreover, the increase in paint consumption tax will also make paint companies more environmentally friendly. Therefore, paint companies should gradually adapt to the country’s policy needs while responding positively to the call for public welfare. Adapt to the country's macro-control in advance.

In this case, paint companies should start with themselves and speed up their transition from the backward industrial chain to the new social mechanisms and social policies and market environment. Change those production processes where resources are expensive and pollution is too great. Constantly improve their own technical level and improve the overall level of our coating industry. Responsible for our environment and responsible for our planet.

WHO: Lead-free paint to be gradually withdrawn from the market

WHO emphasized that the harm caused by lead to children must not be ignored. Young children are particularly vulnerable to the toxic effects of lead and have to suffer severe and persistent side effects on health. Lead especially affects the development of the brain and nervous system. This agency estimates that the number of newly added intellectual disabilities caused by children’s lead exposure is approximately 600,000 annually.

WHO stated that 30 countries around the world have gradually stopped using lead paint, and the global alliance of lead-removing paints co-led by WHO and UNEP has set a goal to stop using it in 70 countries before 2015. Lead paint.

Avoid lead contamination with water paint instead of oil paint

The water-based paint mainly uses water as a diluent, does not contain any toxic and harmful substances, has no peculiar smell during brushing, is environmentally friendly and safe, and has no harm to human health. At the same time, it eliminates the emission of organic solvents and avoids pollution to the environment. Painters use water paints that do not require special labor protection and do not cause any physical damage. The water paint itself also has the characteristics of high hardness, no yellowing, water resistance, heat resistance, good hand feeling, strong adhesion, and good weather resistance.

The paint is one of the major sources of indoor VOCs. Therefore, various countries have imposed limitations on the VOC content of paints and other decorative materials. China’s “Plant Content of Interior Decoration Materials” stipulates that the VOC content in the wall paint shall be ≤200 g/L; the environmental labeling certification standard also requires that the VOC content of the wall paint after water removal be ≤80 g/L; The national standards are more stringent. For example, the VOC content of wall paints in EU standards must be ≤75 g/l.

In developed countries in Europe and America, due to the importance attached to environmental protection and home health, the government passed legislation and forbids painters from using paint, which has promoted the popularity of water paint. As early as 1978, the U.S. federal government banned the production and use of lead-based paints. The penalties imposed on units and individuals selling and using paints containing lead were quite severe. Since 2004, the EU has completely banned the production and sale of paint. The United States also restricted the entry of Chinese paint and furniture into the U.S. market in 2004. In 2007, the U.S. banned toys produced by China from using lead paint in manufacturing. The EU paint market has long been the world of water-based paints, and the use of water paints is as high as 80%-90%.

Before lead-based paints have yet to exit the market, it is recommended by the industry that water-based paints should be the best among water-based and oil-based paints. Most oil paints contain contaminants such as heavy metals, while water-based paints are relatively environmentally friendly. If it can be replaced, use water-based paint as a decorative material.
