A lot of fire-proof material technology involves a lot of complicated contents. According to the principle of fire-proof technology selection, the technology selection is given, the development sequence is determined, and the required technology is classified as fire-proof coating technology, fire-proof board technology, fire-proof sealing material technology, fire-proof decoration material technology, etc. At home, we mainly adopt the idea of integrating the existing and mature technology imported from abroad with the integrated innovation after digestion and absorption as the supplement. In the field of fire technology being developed and to be developed in the world, we should select high and new technologies which have accumulated certain technology and have a significant impact on the fire industry in China, especially green technologies which can improve the quality of fire products and reduce production costs, integrate resources, concentrate efforts and give priority to development. That is to say, combining the selection principle and development approach of fire fighting technology, the selection and development sequence of fire fighting technology in China are made.
It can be seen from some new products that the market of fire-proof materials has changed in recent years. Starting from increasing product safety and practicability, improving durability, introducing energy-saving, resource-saving and cost-saving products, accelerating product renewal, is developing in the direction of high efficiency, energy-saving, environmental protection and saving.
Development of fire retardant coatings technology. Flame retardant is the key part of fire retardant coatings. In recent years, the research of flame retardant technology and the development and application of flame retardant products have attracted attention from all walks of life. The main development directions are: developing multi-effect, high efficiency, low water-soluble dehydration carbon-forming catalyst and foaming agent; rational combination of various flame retardants; combination modification of resins to improve the fire resistance and physical and chemical properties of fire retardant coatings; combination of intumescent and non-intumescent fire retardant coatings; inorganic halogen-free intumescent fire retardant coatings.
Development of fire-proof sheet technology. Compared with traditional sheet metal, modern new environmental protection sheet metal is more popular. It is not only the relationship between price factors, but also the enhancement of people's awareness of environmental protection. Environmental fashion makes sheet metal manufacturers not only pay attention to the price and process of raw materials, but also have very high requirements on the choice of raw materials. The increasing number of high-rise buildings, the emergence of fire protection requirements and high-strength requirements are also re-testing the performance of sheet metal. Some flammable sheets have been restricted to use, and people's concern for environmental protection and health also put forward higher standards for sheets. The development direction is as follows: 1. Inorganic plate. Hard silica-calcium plate is an ideal new decorative fire-proof plate for steel structure fire-proof protection, which represents the advanced international level in the 1990s. It is especially suitable for fire-proof protection and decoration projects of high-rise (super-high-rise) high-level office buildings, high-level hotels, large commercial centers, entertainment centers, computer rooms, large industrial buildings, warehouses and other steel structure buildings and key fire-proof areas. 2. Lightweight plate. Palusol #fire-proof board is a kind of expansive building material. Its main component is sodium silicate hydrate. It expands when heated. It keeps good fire-proof and smoke-proof performance and achieves the effect of heat insulation and noise isolation. The material also has the characteristics of light weight and thin thickness, which is conducive to reducing the cost of building components. Fire doors, fire sleeves and other building components made of Palusol < sheet metal have been used for several years, which is a wise choice for long-term safety and fire protection.
Technical development of fire-proof sealing materials. Building fire-proof plugging materials which have been successfully developed and widely used in fire-proof plugging projects in China are mainly obtained by adding halogen flame retardants. In the case of fire, although halogen materials have good flame retardant effect, they will release a large amount of smoke and hydrogen chloride gas, which can stimulate the eyes and respiratory system; hinder fire fighting and rescue work of firefighters and rescuers; and lead to corrosion of electrical system switches and other metal objects that can not be caused by fire alone. In recent years, more and more countries have enacted or promulgated decrees to test the combustion toxicity of certain products or to regulate the acid gases released from the use of certain products. It has become a trend in the field of flame retardants in the world to develop halogen-free flame retardants instead of halogen flame retardants.
With the development of Intumex Technology in the world, more and more attention has been paid to the development and application of new series of building fire blocking products with high efficiency, environmental protection and construction convenience.
Technical development of flame retardant decoration materials.
The use of flame retardant materials is one of the strategic measures to improve the level of fire safety and reduce fire losses. It helps to improve people's quality of life, reduce disasters and protect the environment. Only through flame retardant, can we ensure the safe use of polymer materials in modern society. Flame-retardant polymer materials are facing challenges from more and more stringent flame-retardant standards and environmental regulations. In the future, flame-retardant materials must meet both requirements, and they must have both.
Technical development of green fire-proof materials. Green fire-fighting technology is based on green chemistry and flame-retardant technology. It uses renewable resources or recyclable materials as raw materials to produce flame-retardant materials. It strives to achieve low toxicity, low smoke and pollution-free of flame-retardant materials. Green fire-fighting technology involves a wide range of aspects, such as clean flame-retardant technology. Successful development of this technology will improve the fire-proof performance of building fire-proof materials, thereby reducing the fire load of buildings, slowing down the spread of fire, reducing the smoke concentration and toxicity of materials during combustion, creating conditions for evacuation and escape from fire, and fundamentally reducing the number of fire disasters. Rate.
With the increasing attention to environmental pollution, the use of solvent-based coatings with high VOC content has been more and more strictly controlled. Environmental friendly coatings mainly include water-borne coatings, powder coatings, light curing coatings, among which water-borne fire-retardant coatings and solvent-free fire-retardant coatings have broad prospects for development. In addition, high solid fire retardant coatings (solid content more than 60%) and liquid solvent-free coatings are environmentally friendly fire retardant coatings with development prospects. Solvent-based fire-retardant coatings account for about 55%, water-based coatings account for about 41% and other coatings account for about 4% in China's market. There is still a big gap between solvent-based fire-retardant coatings and western developed countries.
