Description
Technical Field
The invention belongs to the technical field of fireproof coatings, and particularly relates to a novel environment-friendly fireproof heat-insulating expansion coating and a preparation method thereof.
Background
At present, the intumescent fire-retardant coatings applied in domestic and foreign building fire-retardant engineering can be divided into two categories, namely facing fire-retardant coatings and steel structure fire-retardant coatings, and each category has a plurality of varieties. Generally, the fireproof coating is fireproof because the coating is a common paint film at normal temperature after film formation, and the coating expands and carbonizes in flame or at high temperature to form a nonflammable sponge-like carbon layer which is several tens times thicker than the original film. The coating can obviously reduce the heat transfer and flame retardant effects of external fire sources on the base material, and the components of the coating generate physical and chemical changes under the action of flame or high temperature, so that a large amount of heat energy is absorbed, a part of the heat energy of the external fire sources acting on an object is offset, and the heating process of the protected object is delayed. Meanwhile, the coating has the functions of dehydration and char formation reaction and fusion covering at high temperature, so that air is isolated, organic matters are converted into a carbonized layer, the occurrence of oxidation and heat release reaction is avoided, the coating decomposes non-combustible gases such as ammonia and the like at high temperature, the concentration of combustible gases and oxygen in the air is diluted, and the progress of flame combustion is inhibited.
In production, different kinds of fire-retardant coatings need to be manufactured by adopting different raw materials and different processes and equipment. In terms of application, the fire-retardant coating for combustible substrate veneer generally cannot be applied to the fire protection of steel structure, and the fire-retardant coating for steel structure cannot be applied to the fire protection of combustible substrate veneer. The main reason is that their application range is limited by their respective technical properties, so that several kinds of fire-retardant coatings are respectively coated for one project to meet the fire-retardant requirement of the whole project. Therefore, the process complexity is brought to the production and engineering construction, various devices are needed, the management cost is increased, the cost is increased, and the wide popularization and application are not facilitated.
In the application aspect, both the facing fireproof coating and the steel structure fireproof coating need multiple coating to meet the designed fireproof grade requirement. Therefore, the construction period is long, the construction and management cost is increased, the cost is increased, and the wide popularization and application are not facilitated.
