I. overview of the fire retardant coating market
with the increasing number of high-rise buildings in the design idea of big city 1, and with the development of night economy and stall economy, the urban catering industry and Commerce have shown explosive growth in recent years, and the attention to fire safety is also increasing day by day. In some industries and special industries, the high temperature resistance of their components and products is poor, and the occurrence of fire often causes huge property losses and personal safety hazards. Therefore, in this case, the fire-proof coating came into being. The coating wraps the surface of the object. Even if it comes into contact with the fire source, the film attached to the surface of the object is not easy to burn, and the effect is obvious in protecting the object, so as to rescue personnel and material coating in time before the fire worsens. In, 43% of fires in China occurred in residential buildings, while nearly 20% of fires occurred in public places. It can be seen that the potential downstream demand for fire retardant coatings in construction, industry and agriculture is very wide
fire retardant coatings are mainly divided into steel structure fire retardant coatings, tunnel fire retardant coatings, cable fire retardant coatings, decorative fire retardant coatings, etc. according to the different protection objects. According to different fire-proof principles, fire-proof coatings can be divided into non expansive coatings and expansive coatings. Fire retardant coatings are widely used in the following five categories: construction, such as industrial plants, warehouses, large stadiums, high-rise buildings, airports, railway stations, bus stations, urban tunnels, railway tunnels and other projects. Fire protection of transportation structures, such as aircraft, ships, ships and so on. Fire protection for chemical industry, petrochemical projects, refineries, pipelines, oil tanks and reactors. Fire protection of electronics, such as chips and black boxes. Electric power, such as cable fire retardant coating, fire protection of UHV converter station. In 2018, the output of China's fire retardant coating industry reached 125600 tons, about less than 1% of the total coating output that year, belonging to a small-scale market with rapid growth
II. Main types of fire retardant coatings
the weak and stable operation of fire retardant coatings in the domestic mining market is generally composed of base materials, dispersion media, flame retardants, additives and solvents. In the early years, fire retardant coatings were mainly made of intumescent fire retardant raw materials, and intumescent fire retardant coatings did not gradually enter the market until recent years. Non intumescent coatings are also known as thick fire retardant coatings. Thick fire retardant coatings with organic polymers as film-forming materials are also known as flame retardant coatings. Thick fire retardant coatings composed of inorganic light materials, reinforcing materials and adhesives are the mainstream fire retardant coatings in the domestic market at present. Among them, cement-based thick fire retardant coating is widely favored by the market because of its low price. The advantage of thick fire retardant coating is that it has a long high temperature resistance time, and the fire resistance limit can reach 3h, which is much higher than the 1 ~ 2H that the existing thin and ultra-thin fire retardant coating can withstand. Therefore, thick fire retardant coating should generally be used under outdoor working conditions that require a long fire resistance time, but the thick fire retardant coating has poor decoration and needs regular maintenance
the variability of intumescent fire retardant coating jjg1136 ⑵ 017 is the concept of volatility, that is, thin and ultra-thin fire retardant coatings, which are mainly composed of film-forming substances, carbon sources, acid sources, foaming agents and fillers. Its fire-proof effect is not as good as that of thick type, but its decoration is better. At room temperature, the coating thickness of intumescent fire-proof coating after film formation is thinner, which is conducive to meeting the requirements of decoration. However, due to the inability of aqueous solvents to meet the performance requirements of coatings, solvent based resins are commonly used as substrates, which may cause environmental pollution, which is also its significant disadvantage. However, at present, the weather resistance of ordinary ultra-thin fire retardant coatings is poor, which can only be applied to indoor roof beam structures
III. enterprise distribution
fire retardant coating is classified as one of building coatings. Due to the high environmental protection policies and the technical threshold of related products, the number of enterprises in China's fire retardant coating market is relatively small. Until 2016, there were only more than 200 enterprises producing fire retardant coating, which is not fully competitive compared with the whole coating industry. From the perspective of the regional distribution of enterprises, it is mainly affected by factors such as production technology and market demand. At this stage, the production enterprises of thermal insulation and fire retardant coatings for steel structures in China are mainly distributed in the coastal areas of East China, followed by Beijing Tianjin and the Pearl River Delta, and the industry shows obvious regional characteristics
at present, the main production enterprises in China's fire retardant coating market include AkzoNobel, Xuanwei of the United States, Beijing Jingtai, Jiangsu Lanling chemical industry, Jotun, Jiangsu champion, Hunan Huaxinyuan and other enterprises. On the whole, China's steel structure heat insulation and fire retardant coating enterprises are dominated by small and medium-sized enterprises, with few large enterprises and low market concentration. On June 1st, 2019, the state officially implemented the new national standard for fire retardant coatings, "fire retardant coatings for steel structures (GB)". Compared with the old standard, the new standard has 13 additions, modifications and deletions, including increasing the heat insulation efficiency test, modifying the fire resistance test method, increasing the ultraviolet radiation resistance, etc., which will pose a great challenge to the future research and development ability of enterprises, and the industry concentration is expected to improve in the future
IV. development trend of fire retardant coating industry
considering the construction difficulty and decoration of the coating, Ultra-thin Intumescent fire retardant coating is a fire retardant coating product with a wide range of applications in the future. Ultra thin intumescent fire retardant coatings have been continuously developed, from base materials to fire retardant additives. At present, the market share of ultra-thin fire retardant coatings accounts for 70% of the total sales of fire retardant coatings. From the perspective of development trend, ultra-thin fire retardant coatings for steel structures will replace thick and thin fire retardant coatings for steel structures. At present, the main problem of ultra-thin coatings is that they are flammable and explosive, volatile and seriously polluting the environment. The research and development of fire-proof coatings with thermal insulation, sound absorption, radiation protection, UV protection, corrosion resistance and other multi-functional integration, and the composite function is a major topic in the research and development of fire-proof coatings
