Problems solved by technology

[0004] In order to solve the common problems of existing slag, high-silicon bauxite, stainless steel slag, phosphorus slag and manganese slag, which are poor in grindability, easy to agglomerate, and cannot be large-scale and high-value-added; the thermal stability of existing epoxy organic adhesives Poor, long-term chemical stability is poor, and the upper limit of temperature resistance is less than 80°C; the existing inorganic rubber has insufficient shear force; high-silicon bauxite, stainless steel slag and phosphorus slag all have certain flame retardancy. However, there is a problem that they cannot be synergistically flame-retardant
