Fire-retardant coatings, also known as fire-retardant coatings, are mainly classified into two types: veneer type and steel structure fire-retardant coating according to their use. According to the change state of the coating after fire, they can be divided into two types: expansion type and non-expansion type. . At present, China's steel structure, as a form of high-rise building structure, is widely used in the construction industry because of its high strength, light weight, good elongation, shock resistance and short construction period, especially in the super high-rise and large The span building and other aspects show great vitality. The manufacturer of high temperature resistant thermal insulation coatings, Beijing Zhisheng Weihua Chemical Co., Ltd., its ZS-1 high temperature thermal insulation coating is a water-based environmentally friendly coating with a thermal conductivity of 0.03W/mK and a temperature resistance of 1800 °C for a long time. Refractory grilling can effectively suppress various conductive heat and radiant heat, and the heat insulation inhibition efficiency can reach 90%. The coating is coated with 8mm thick on the surface of the object at 1100 °C. The temperature of the surface of the object can be reduced from 1100 °C to 100 °C. Only 6 mm thick high temperature insulation is applied on the outer surfaces of industrial furnaces, furnaces, blast furnaces and steel structures. Coatings can reduce heat loss by more than 30%. ZS-1 coating is fire retardant, insulating and wear resistant, acid and alkali resistant, light in weight, good in heat insulation effect, convenient in construction and long in service life. With the development of China's urban scale, the application of steel structure in China's construction industry has a very broad prospect. However, due to the incombustible steel structure itself, the problem of fireproofing and heat insulation protection of steel structures was once neglected. Relevant tests and statistics show that the fire resistance of steel structures is worse than that of masonry and reinforced concrete structures. The mechanical strength of steel decreases with increasing temperature. At 5,000 °C, its strength drops to 40% to 50%. The mechanical properties of steel, such as yield point, compressive strength, modulus of elasticity and load capacity, are rapidly decreasing. , quickly lost support, leading to collapse of buildings. Therefore, it is imperative to protect the steel structure. The steel structure fireproof coating is painted or sprayed on the surface of the steel structure to prevent fire and heat insulation, prevent the steel from heating up rapidly in the fire and reduce the strength, and avoid the steel structure losing support ability and causing the building to collapse. With the development of the coating industry towards performance, high energy efficiency and low pollution, this will enable the development of new inorganic environmentally friendly fire retardant coatings to become the development direction of fire retardant coatings. ZS-11 Intumescent High Temperature Insulation Coatings developed by Beijing Zhisheng Weihua Chemical Co., Ltd. is the world leader in coating technology. The company has core technology patents. The coating adopts Zhisheng Weihua's special solid-phase solidification film-forming solution as a film-forming material. The coating filler is made of high-temperature inorganic nano-materials---alumina, zirconia, carbon fiber, hollow carbon nanotubes, expanded graphite, silicon carbide. It is made by high temperature and high pressure finishing. The coating can be expanded after being heated, and the volume expansion ratio of the coating can be more than 5 times. After the coating is expanded, a plurality of independent pattern vacuum layers can be formed in the coating, and the coating does not fall off after being thermally expanded. The coating can withstand temperatures up to 2000 ° C. The thermal conductivity of the fully expanded coating layer can reach 0.022 W/mK (tested at 70 ° C, and the coating is cooled after heating at high temperatures). ZS-11 Intumescent High Temperature Insulation Coatings are solidified by solid phase principle and can control the formation and growth of crystals. They can be applied on any organic or inorganic materials. The adhesion is good and the coating can be heated. High temperature above 1000 °C, the coating is fully expanded, exerts excellent thermal conductivity, and has the best thermal insulation effect. After the coating is cured, because of the selection of inorganic nano-filler, it has good acid and alkali resistance and can be well protected. The substrate is not oxidized by high temperature corrosion, the coating has smooth and high hardness, good wear resistance, long-term resistance to open flame, fire rating can reach Grade A, and the coating construction is convenient. It is a veritable steel structure water-based fireproof coating. The development of industry, the increase of solvent prices, the increase of energy consumption and the strict control of waste discharge, the development and research of water-based coatings to replace solvent-based coatings based on toxic organic solvents, has become an important aspect of the development of the world coatings field. ZS-11 expansion type high temperature resistant thermal insulation coating is undoubtedly in the forefront of the world.
