Flame retardants are mainly functional additives designed to hinder the combustion of polymer materials and impart flame retardancy to flammable polymers. According to the method of using the combustion promoter, it can be divided into additive flame retardant and reactive flame retardant. Additive combustion aids are added to the polymer by mechanical mixing to make the polymer flame retardant. The reactive combustion promoter is used as a monomer to participate in the polymerization reaction to make the polymer itself flame-retardant.
Flame retardants are mainly used to increase the flame resistance of polymer materials, such as plastics, rubber, and fibers. These materials are difficult to degrade in the natural environment, causing pollution to the ecological environment. In order to quickly detect pollutants in the environment, flame retardant analysis standards are often used as reference materials for rapid qualitative and quantitative analysis. At the same time, it can also be used to assess whether the material meets the use standard.
Application fields
Environmental test: Phosphoric acid and halogenated compounds have certain toxicity, and their loss to the environment can cause serious pollution to organisms, plants, soil, and water. If it enters the human body through the ecological cycle, it will cause harm to human health. In environmental testing, the testing of flame retardants is one of the important standards for environmental considerations. There are many kinds of flame retardants, and the workload of blind inspection is very huge without the comparison of standard samples. For analytical methods such as chromatography and spectrophotometry, flame retardant analytical standards can be used as references for qualitative and quantitative analysis.
Material quality standards: Most fiber products, plastics, rubber and other materials contain flame retardants. These materials are commonly used in human life. If the flame retardant content in the material exceeds the standard, it may be absorbed by the body and cause harm. Therefore, materials must pass quality inspection standards before they enter the market. This standard can be analyzed by using flame retardant analysis standards to obtain the content of flame retardant in the material to determine whether the material meets the use standard.
