In recent years, with the continuous expansion of the scale of urban construction in our country, the roof forms of residential buildings have also undergone tremendous changes. Various forms of roofs with various shapes and colors have emerged, especially in many coastal cities. The "flat to slope" project has added new highlights to the living environment of local residents. Because the color asphalt tile has the dual functions of waterproofing and decoration, and its light weight, cold construction, pollution-free, simple and fast, low cost, it is more favored by people. Recently, the Ministry of Construction issued design standards for improving the envelope structure of residential buildings, advocating energy conservation and reducing emissions, which not only helps to improve the quality of life of residents, but also further promotes the development of colored asphalt roof shingle.
However, changes in architectural design and the use of new building components have placed increasing demands on roofing waterproofing materials. In September 2009, the Ministry of Public Security and the Ministry of Housing and Construction issued the "Temporary Provisions on Fire Protection of Exterior Thermal Insulation Systems for Civil Buildings and Exterior Wall Decorations", which requires that the burning performance of exterior insulation materials including facades should be Class A and should not be low. At level B2. For roofing waterproofing materials, the development trend is to improve the flame retardant performance, while having low carbon efficiency, green environmental protection and sustainability. Among various types of roof waterproofing materials, asphalt tiles not only have excellent waterproof performance, but also have good fire safety. Existing asphalt shingle technology is mainly focused on improving the conventional performance and design structure of asphalt shingles. Many asphalt shingles supplier seldom consider energy saving, flame retardant, flame retardant, engineering application and other issues in formula optimization.
For flame retardant asphalt shingles, the key to its production process is the preparation of flame retardant asphalt mixtures (that is, coatings. The flame retardant asphalt mixture is prepared by adding an appropriate amount of flame retardant to the asphalt and through a certain modification process. The flame retardant asphalt material is designed, and the asphalt mixture is designed to prepare an asphalt coating material which has flame retardant performance and meets the technical requirements for use performance. The flame retardant asphalt is modified by adding a flame retardant to the asphalt The result is that the flame retardant is usually mechanically mixed with the asphalt and does not react chemically with the asphalt. The addition will have a certain effect on the performance of the asphalt, and the greater the amount of the flame retardant, the greater the impact on the performance. .
Therefore, in the preparation of flame retardant asphalt, it is necessary to control the amount of addition, select a flame retardant that has a good flame retardant effect and has a small effect on asphalt performance, and perform flame retardant modification. Some flame retardants have a synergistic effect when they are flame retardant. That is, when two flame retardants are present at the same time and have a flame retardant effect, the flame retardant effect is greater than the sum of the flame retardant effects of the two flame retardants. Therefore, you can find several flame retardants with flame retardant synergistic effect to modify the flame retardant effect to improve the flame retardant effect. At the same time, under the same flame retardant effect condition, when using a composite flame retardant with flame retardant synergy effect, It can reduce the amount of flame retardants added, thereby improving the application performance of asphalt. When a fire source or fire occurs, the flame retardant asphalt tile starts to play its role, the temperature of the flame retardant asphalt tile rises, and the flame retardant asphalt and the flame retardant are also heated at the same time, the asphalt starts to decompose, and the flame retardant begins to exert flame Effect, so that the asphalt tile achieves the flame retardant effect, reducing the loss of fire.
