Background
Industrial solid waste refers to solid waste produced in industrial production activities. The solid waste is waste residue, dust and other waste discharged into environment during industrial production. Can be divided into general industrial waste (such as blast furnace slag, steel slag, red mud, nonferrous metal slag, fly ash, coal slag, sulfuric acid slag, waste gypsum, desulfurized ash, carbide slag, salt mud and the like) and industrial harmful solid waste, namely dangerous solid waste. The stockpiling of industrial solid wastes occupies land, pollutes toxic soil, water body and atmosphere, seriously affects ecological environment, and causes obvious or potential economic loss and resource waste. Therefore, the harmless and recycling treatment of the industrial solid waste is a focus of great importance in China and even countries around the world, and is one of the central contents for promoting the recycling economy in the countries, so that the development of the comprehensive utilization of the industrial solid waste has important significance.
With the improvement of national economy and the continuous development of scientific technology, polymer materials such as plastics, fibers, rubber and the like and products thereof have been vigorously developed in recent years, and the polymer materials are gradually replacing some traditional materials such as: materials such as steel, metal, cement and wood are widely applied to various fields such as industry, agriculture and military. The polymer has the characteristics of small relative density, good chemical resistance, good water resistance, good mechanical strength, electrical insulation and the like. Can be used for films, pipes, plates, various molded products, wires and cables, etc. The product has wide application in agriculture, packaging, electronics, electricity, automobiles, machinery, daily sundries and the like. The chemical components of industrial solid waste mainly comprise CaO and SiO 2 、Al 2 O 3 、MgO、MnO、Fe 2 O 3 Isooxides and small amounts of sulfides such as CaS, mnS, etc., generally CaO, siO 2 And Al 2 O 3 The content of (2) is more than 90%. Wherein CaO, siO 2 And Al 2 O 3 Is often used as a filler for filling polymer products, reducing the price of the product. Therefore, the industrial solid waste composite material can be prepared by compounding industrial solid waste and polymers, so that the problem of environmental pollution caused by industrial solid waste is solved, and the cost of the polymers can be effectively reduced.
