Fire retardant paint has broad prospects in the application of organic synthetic materials
fire retardant varnish, also known as transparent fire retardant paint, is a kind of decorative fire retardant paint developed and maturing in recent years. After adding pigments, it is our common fire retardant paint, which is mainly used for the fire protection of high-grade wood decorative materials and the steel structure surface of buildings or structures. Its products shall meet the requirements of GB general technical conditions for decorative fire retardant coatings and GB general technical conditions for fire retardant coatings for steel structures. At present, the commonly used fire-proof paint in China is intumescent, which is mainly used on the surface of wood decorative materials. When the surface of the object coated with and then made into implant fire-proof paint meets fire, the fire-proof paint can expand rapidly in a short time, delaying the development of combustion
fire retardant paint is generally composed of synthetic non combustible or refractory organic polymer resin. The organic polymer resin is modified by special groups, and the resin itself can contain a certain amount of flame retardant groups and foaming groups, and then a small amount of foaming agents, flame retardants, carbon sources, etc. are added to form a fire prevention system. Under normal circumstances, fireproof paint, as the exterior decoration layer of high-grade wood decorative materials, has good decorative effect; When exposed to fire, it can expand and form a uniform and dense honeycomb or spongy carbon foam layer to isolate the flame from the object, prevent or delay the combustion, so as to achieve the purpose of extinguishing the fire and have a good protective effect on the combustible substrate. At the same time, the pigments used in fire-proof paint are often used if the experimental compliance value of the experimental machine has been used. Titanium white, antimony white, mica and asbestos are normally used, because these pigments have high heat dissipation efficiency and are also conducive to fire prevention. Among them, antimony white has strong reflection ability to infrared ray, and can reflect heat in case of fire - the flexible manufacturing capacity for personalized needs is widely used in fire-proof paint
the application of fire-proof paint in organic synthetic materials has broad prospects. With the large-scale application of organic synthetic materials, non combustible organic polymers such as halogen often lead to the deterioration of material properties, shortening of service life and increasing price. Adopting the method of coating fireproof paint on its surface for fire protection can not only maintain the excellent performance of the original organic synthetic materials, but also be economical and applicable. In addition, ordinary steel loses its structural strength when heated to about 540 ℃. Concrete structure is also easy to crack and collapse under the action of high temperature flame. Therefore, fire protection for steel structures and concrete structures can ensure that the processed sample gap is 100% qualified, so that they can prolong the time of deformation and damage in the event of fire, win time for fire fighting and reduce fire losses, which has been paid great attention by people. The application of fire retardant coatings in steel structures and cement structures is expanding
