Abstract

The invention discloses environment-friendly fireproof paint produced by using solid waste of the steel industry as raw materials. The environment-friendly fireproof paint produced by using the solidwaste of the steel industry as the raw materials is produced from the following raw materials of, in parts by weight, 30-35 parts of cement, 6-10 parts of mica powder, 5-7 parts of modified sodium silicate powder, 12-18 parts of steel slag powder, 4-8 parts of water granulated slag powder, 25-35 parts of coal ash floating beads and 2-4 parts of hydrophobic silica. The main raw materials of the environment-friendly fireproof paint come from the solid waste generated in the steel industry, comprise steel slag, water granulated slag and coal ash and account for over 50% of the raw materials for producing the environment-friendly fireproof paint, so that resource utilization of the steel bulk solid waste is achieved, and the environment-friendly fireproof paint is in conformity with the principles of environmental protection and sustainable development. The environment-friendly fireproof paint is novel non-bulgy fireproof paint, is light in weight, low in cost, simple in production technology, simple and convenient to construct, environmentally friendly, safe and extremely high in cost performance, has a good fireproof effect, can be used as ultra-thin and thin fireproof paint, and iswidely used as fireproof protective materials of different fields of steel structures, concrete structures and the like.

Description

technical field [0001] The invention relates to the technical field of industrial waste treatment and preparation of environmentally friendly coatings, in particular to an environmentally friendly fireproof coating prepared from solid waste in the iron and steel industry. Background technique [0002] The iron and steel industry is a pillar industry of China's national economy and plays an irreplaceable role in the process of industrial modernization. The iron and steel industry is an energy- and resource-intensive industry, and the solid waste generated accounts for about 13% of the total volume of bulk industrial solid waste. The bulk solid waste in the iron and steel industry mainly includes water slag, steel slag, fly ash, desulfurized gypsum, and iron-containing dust and sludge. In 2017, the national production of pig iron and crude steel showed positive growth. According to calculations, in 2017, the country produced about 213.2277 million tons of blast furnace slag,...
