Embodiment 1
[0022] 1. Raw materials:
[0023] The composition of polymetallic tailings is shown in Table 1.
[0024] Table 1 Multi-element analysis results of polymetallic tailings (%)
[0025] the element
[0026] The mineral composition of tailings is mainly quartz, garnet, feldspar, calcite, mica, hornblende, diopside and so on. The tailings fineness -0.074mm accounts for 70.35%, and the garnet mineral content in the tailings is 35%.
[0027] 2. Key equipment: (all existing equipment)
[0028] High gradient strong magnetic separator; φ25 hydrocyclone; disc vacuum filter; 101 electric oven.
[0029] 2. The specific operation process:
[0030] See the process flow figure 1 . After the tailings containing garnet are pre-enriched in a spiral chute, the garnet is further enriched by magnetic separation, and the concentrate is garnet concentrate by strong magnetic selection.
[0031] After the tailings containing garnet are pre-enriched in a spiral chute, the effect of magne...

Abstract
The invention provides an application of garnet micro powder serving as filler in an epoxy resin adhesive as well as an epoxy resin adhesive. According to the invention, garnet-containing tailings are taken as raw materials, a reselection-magnetic separation-classification combined process is adopted to recover minus 0.045mm-garnet micro powder, the mineral content of the garnet micro powder is higher than 60%, and the garnet micro powder serves as the refined filler in the epoxy resin adhesive. When the garnet micro powder serving as the filler is applied to the epoxy resin adhesive, the filling amount can be higher than 60%, the performance of the prepared epoxy resin adhesive can meet the adhesive and concrete repair material index in GB50367-2006 Design code for strengthening concrete structure, wear resistance, compression resistance and corrosion resistance of the epoxy resin adhesive are improved, the material cost is reduced, and the garnet micro powder has larger development space and broader market prospect when applied to the epoxy resin adhesive.
Description
technical field [0001] The invention belongs to the field of inorganic materials, and in particular relates to a new application of garnet micropowder and an epoxy resin adhesive. Background technique [0002] Epoxy adhesives have the advantages of strong adhesion, high bonding strength, small curing shrinkage, excellent electrical properties, good dimensional stability, strong creep resistance, chemical resistance, low toxicity, and no environmental pollution. It has good bonding ability to metal, wood, plastic, glass, ceramics, composite materials, concrete, rubber, fabric and many other materials. In addition to the bonding performance, it also has the functions of sealing, plugging, insulation, anti-loosening, anti-corrosion coating, wear resistance, electrical conductivity, magnetic conduction, heat conduction, fixing, reinforcement and repair, decoration, etc. It can be widely used in industrial fields such as chemical industry, light industry, water conservancy, tran...
