recently, a worker poisoning accident occurred at the decoration and reconstruction project site of a unit in this city. According to the investigation, the reason for the accident is that the waterproof coating and diluent used by workers during the construction of waterproof coating release toxic gas

waterproof coating causes environmental pollution

recently, many consumers have come to the city's indoor environmental monitoring department for consultation, reflecting that there is a relatively strong smell in the sanitary

Room and kitchen after home decoration. The relevant departments found that the pollution was mainly caused by waterproof coating, and this pollution was not easy to remove. Ms. Wang, who lives in Jiulong garden, had no choice but to dismantle the decorated bathroom and carry out waterproof treatment again. Therefore, experts from the indoor environment monitoring center remind everyone: while paying attention to the pollution of wood-based panels, paint coatings and radioactive stones in decoration, don't ignore another important link of indoor decoration pollution - indoor environment pollution caused by waterproof coatings

at present, in building decoration projects, waterproof treatment should be carried out for places that are often contaminated with water, such as kitchens and toilets

some decoration companies and consumers believe that the area of waterproof treatment for indoor decoration is not very large, and there are cement and tiles on it after treatment, so the pollution will not be very serious. It's not true. Because the indoor waterproof layer generally has to reach a certain thickness before it can have the corresponding waterproof function, and the use of materials is relatively large. Once the waterproof coating containing pollutants is used in the waterproof construction, it will cause indoor environmental pollution for a long time

polyurethane waterproof coatings are harmful to human health

the indoor environmental monitoring center found that some polyurethane waterproof coatings containing tar are seriously polluted. Wei et al. Compounded the functionalized graphene and polyaniline nanoparticles to obtain a capacitance of 1046f/g. Such materials are generally made of coal tar or raw materials containing part of coal tar, and the volatile coke

oil and gas has a pungent smell. At the same time, due to the relatively large molecular weight of tar gas, it is easy to deposit in the indoor environment with poor air circulation, and excessive inhalation of tar gas in a short time can lead to rapid poisoning and death. In addition, another defect of this kind of waterproof coating is the use of organic solvents as diluents, which mostly contain toxic substances such as toluene and xylene. Due to the dense surface of the waterproof coating, the solvent takes a long time to volatilize. Although lithium only accounts for about 2% of the weight of the aluminum alloy, the pollutants will be released within a certain period of time after the completion of this decoration project. Inhalation of tar gas and benzene in small doses for a long time can cause

respiratory diseases, dizziness, nausea, and even cancer. At present, this kind of material, which adopts the same sample under the specified state conditioning conditions, temperature, humidity and strain rate, has been listed as obsolete building decoration materials by the relevant national and local departments, and is not allowed to be used in building decoration projects

choose non-toxic and environmental protection products

control indoor decoration. 2. According to the measured hardness units, the pollution of waterproof paint for decoration should be controlled mainly from the aspect of materials used. We should first choose non-toxic and environmental protection waterproof paint. At present, there are acrylic waterproof coatings and tar free polyurethane waterproof materials on the market, which have been proved to be non-toxic, tasteless and environment-friendly products. Only the indoor floors treated with this kind of waterproof coatings can achieve environmental protection. At the beginning of the implementation of the ten mandatory standards for the limit of harmful substances in indoor decoration materials formulated by the state, When all walks of life implement the national law on the prevention and control of occupational diseases and the production safety law of the people's Republic of China, the accidents caused by the problems of interior decoration materials have once again sounded the alarm for us: indoor environmental pollution should not be ignored
