With the continuous improvement of people's living standards, people's requirements for living paper are becoming higher and higher, especially in some special occasions, paper is required to have certain flame-retardant properties. Below, Dow and everyone analyze how wood flame retardants can improve the flame retardant properties of paper.

The main components of paper are cellulose, hemicellulose and lignin. To perform flame retardant treatment on paper is to find ways to hinder the thermal decomposition of cellulose and suppress the generation of flammable gases, so as to achieve the purpose of fire prevention and fire extinguishing. There are three main aspects of the flame retardant approach of wood flame retardants: first, heat absorption. The flame retardant absorbs heat to reduce the temperature of the paper, thereby playing the role of flame retardant. Second, dilution. The flame retardant will produce a large amount of non-combustible gas during the flame retardant process, thereby reducing the concentration of combustible gas. Third, isolation. A layer of insulation film is produced during the flame retardant process, which can block oxygen.
