Abstract
The invention discloses a molding compound containing iron ore tailings. The components include iron ore tailings, epoxy vinyl resin, polystyrene, magnesium oxide, tert-butyl peroxybenzoate, glass fiber, and color paste . The present invention can greatly improve the strength and hardness of the product by adding iron ore tailings to make the molding compound. Since the treatment of iron ore tailings has been plagued by domestic steel plants, the application of iron ore tailings in the molding compound is to improve the moldability. The quality of plastic products enables the comprehensive utilization of iron ore tailings with better added value.
Description
technical field [0001] The invention relates to a molding compound containing iron ore tailings, in particular to a material suitable for making glass fiber reinforced molding products, and belongs to the technical field of resource reuse. technical background [0002] As one of the pillar industries of the national economy, the iron and steel industry is even more important, especially in my country's rapid development of the national economy. However, with the deepening of mines, the ore grade is declining, the amount of tailings and the corresponding investment are gradually increasing, and the recycling of tailings resources has become a major content of mining development. There are more than 400 tailing ponds in our country, directly polluting one million mu of land, and indirectly polluting about 10 million mu of land, and the annual transportation cost is as high as 7.5 billion yuan. Tailings not only contain a certain amount of iron, but also contain other valuable...
