Problems solved by technology

The disadvantages of water-based coatings are also quite obvious. On the one hand, the current conventional water-based coatings are not ideal, and the hardness of the film is far from that of oil-based coatings; on the other hand, the solvent in water-based coatings is water, and its evaporation heat is relatively low. Large, slow drying speed in the coating process, which seriously limits its popularization and application

Abstract

The invention provides a waterborne environment-friendly refractory coating as well as a preparation method and application thereof. The preparation method comprises the steps that a film-forming basematerial and a quaternary ammonium salt type trimeric surfactant are mixed and ground so as to prepare a first material; then organic montmorillonite, ammonium polyphosphate, aluminum dihydrogen tripolyphosphate and sodium hexametaphosphate are mixed and ground so as to prepare a second material; and finally, a defoaming agent and a dispersing agent are added into the first material, grinding iscarried out, then the second material is continuously added, and full grinding is carried out so as to obtain the coating. The coating is a waterborne system, the content of volatile organic compounds(VOC) is low, the environmental protection standards are met, the film forming performance on the surface of a liner of an industry kiln is excellent, and the refractoriness is good.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based environment-friendly refractory coating and a preparation method and application thereof. Background technique [0002] For industrial furnaces such as heating furnaces, soaking furnaces, thermal power plant boilers, and metal heat treatment furnaces, it is usually necessary to protect the surface of the lining to reduce the direct erosion of the lining by flames and high-temperature gases, and improve the service life of the lining. Paint is certainly a very convenient option. The use of refractory coatings can make the inner lining more sealed and insulated, reduce the heat loss of industrial furnaces, increase the heating speed and yield, and also increase the overhaul cycle, save costs, and play a role in protecting and saving energy. [0003] However, the existing protective coatings have various problems such as not being environmentally friendly and having ...
