No 20140296-q-606 project name: Standard nature of limit of harmful substances in indoor floor coating mandatory revision time 2014 competent department Purpose and significance of the national paint and pigment Standardization Technical Committee, the centralized unit of China Petroleum and Chemical Industry Federation: indoor floor coating is widely used in production and operation places, home and commercial markets of various industrial enterprises for its advantages of good adhesion, adhesion, wear resistance, excellent alkali resistance and corrosion resistance According to different requirements of places, different floor decoration effects can be obtained by selecting floor coatings with different functions and artistic effects Because it is used indoors, the harmful substances contained in the paint will cause certain harm to the indoor environment and human body In recent years, the problem has also been highly concerned and valued by the relevant industries and consumers Some floor coating users, especially some pharmaceutical factories and food processing factories, have begun to pay attention to the environmental protection of floor coating, requiring the floor coating supplier to conduct the inspection of harmful substances in floor coating Recommended standard 2 Plan No 20140493-t-606 project name of water-based Wood Coatings for children's room decoration recommended preparation and revision time of standard property of water-based Wood Coatings for children's room decoration 2015 competent department under the jurisdiction of China Petroleum and Chemical Industry Federation National Technical Committee for coating and pigment standardization purpose: Children's skin is tender compared with adults The body has poor resistance and is vulnerable to air pollution In addition, children's behavior is different from that of adults They like to rub around and paint When parents in Europe and the United States decorate children's houses, they will choose children's special paint It is specially made for children's physical and behavioral characteristics, which is more environmentally friendly and healthy, and beneficial to children's physical and mental development At present, the wood coatings sold in our market are mainly solvent based, and the varieties and quantity of water-based wood coatings are less There are a lot of harmful substances in solvent wood coatings, which are not recommended for children's room decoration Some waterborne wood coatings in the market also have high VOC content Some products may bring plasticizer and other chemicals due to raw materials and other reasons, which may cause certain potential harm to children's health With the improvement of people's living standards, many parents consider buying water-based Wood Coatings with lower harmful substance content and better coating performance when decorating, so as to create a healthier and safer living environment for children At present, China's relevant standards for waterborne wood coatings include the compulsory harmful substances standard gb24410-2009, the limit of harmful substances in Waterborne Wood Coatings for interior decoration materials, and the physicochemical performance standard GB / t23999-2009, water-based Wood Coatings for interior decoration, in which the varieties and limits of harmful substances set in gb24410-2009 do not take into account the physiological characteristics of children, and those set in GB / t23999-2009 Some performance test items do not consider children's living habits, such as green tea and vinegar, which are the pollution sources of pollution resistance These pollution sources will not appear in children's houses, and the wear resistance and pencil hardness index reflecting scratch resistance need to be improved Because there is no uniform and applicable standard of water-based Wood Coatings for children's room decoration, many consumers are fond of water-based wood coatings, but there is "no concept" on how to judge and select the water-based Wood Coatings for children's room decoration No matter when consumers purchase or paint manufacturers promote, there is no reference standard, which inevitably leads to confusion The lack of standards not only makes it difficult for consumers to choose water-based Wood Coatings for children's room decoration, but also makes the quality of water-based Wood Coatings for children's room decoration vary in the market There are "children's water-based Wood Coatings" with high price and no difference between internal quality and common water-based Wood Coatings In order to help consumers better choose water-based Wood Coatings for children's room decoration and promote the healthy development of the market, it is recommended to formulate the national standard of water-based Wood Coatings for children's room decoration, so as to create a healthy home atmosphere for children In view of the water-based Wood Coatings for children's room decoration are mainly to meet the market demand of different levels, and the characteristics of close contact with toy coatings and children are also different, so it is not necessary to enforce them, and it is enough to formulate recommended standards Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating
