Description
Technical field
The invention belongs to field of inorganic materials, and in particular to the new application of garnet micropowder and a kind of epoxy resin are gluing
Agent.
Background technology
Epoxy adhesive has that cohesive force is big, adhesion strength is high, cure shrinkage is little, excellent electrical properties, dimensionally stable are good, anti-
Croop property is strong, resistant to chemical media, toxic are very low, the advantages of non-environmental-pollution.To metal, timber, plastics, glass, pottery,
The multiple materials such as composite, concrete, rubber, fabric all have good cementitiousness.In addition to adhesive property, also
Sealing, leak stopping, insulation, locking, anti-corrosion snearing, wear-resisting, conductive, magnetic conduction, heat conduction, fixation, reinforcing and repairing, decoration etc. are acted on.Can
It is widely used in the industrial circles such as chemical industry, light industry, water conservancy, traffic, machinery, electronics, household electrical appliances, automobile and space flight and aviation.
Epoxy adhesive be with epoxy resin (component A) and firming agent (B component) by certain weight ratio be configured to high temperature resistant,
The big curing system of good toughness, reactivity.Wherein component A adds auxiliary agent and filler stirring to form based on epoxy resin.
The addition of filler can reduce the consumption of epoxy resin, and reduces cost, can also improve comprcssive strength and wearability, reduction heat are swollen
Swollen coefficient, shrinkage factor, exothermic temperature etc..Although the consumption of auxiliary agent is less, very important mechanicalness to product is acted on
Energy, electric property, wet and heat ageing resistant performance etc. are very useful.Be usually used has coupling agent, wetting dispersing agent, defoamer, anti-
Old agent etc., also includes epoxy mill base etc. if necessary.Component A is the main body of adhesive, itself will not solidify under normal temperature condition, adds
Firming agent can carry out cross-linking and curing reaction, generate build network structure, with many premium properties.B component (firming agent) is used for
Curing reaction is carried out with epoxy resin, process condition can be improved while engineering property requirement is met.
Filler is a kind of solid material, interacts with the physical characteristics by itself and surface, or has surface mutual
Effect, change the ability of Material Physics and chemical property.As filler improves the effect is significant of matrix material performance, and energy
Reduce the cost of material to a certain extent, so the application of filler is more and more extensive.Add in epoxyn and fill out
Material not only can reduces cost, can also improve many performances of adhesive, such as reduce thermal coefficient of expansion and cure shrinkage, raising
Adhesive strength, thermostability and wearability etc..
Content of the invention
Contain garnet in the Ore of mining, enter substantially tailings discharging, the stone containing 20～40% in mine tailing
Garnet, reclaims garnet and can reduce tailings discharging amount.It is an object of the invention to provide a kind of new application of garnet
And a kind of epoxyn is prepared with which, can be very good to utilize recovery in garnet, particularly mine tailing to obtain
Garnet micropowder., as filler in epoxy adhesive better performances, oil absorption is low, good dispersion for garnet micropowder, compared with
Big raising adhesive hardness and anti-wear performance, can fill as epoxyn, concrete repairing material and epoxy resin
Slurry is used, and is especially made road surface and is strengthened high-abrasive material application, is played road surface and is strengthened reinforcing.
For achieving the above object, the technical solution adopted in the present invention is：
Application of the garnet micropowder as filler in epoxyn, the garnet micropowder are average grain
Footpath is in below 0.045mm, and garnet mineral content reaches more than 60% garnet breeze.
The garnet micropowder is preferably obtained by the following method：With metal tailings as raw material, entered using spiral chute
Row preenrichment, magnetic separation, magnetic field intensity are (75-85) × 104A/m, obtains garnet concentrate；It is classified using water conservancy, reclaim-
The garnet micropowder of below 0.045mm, dehydration are dried and obtain garnet breeze.
The metal tailings refer to the mineral containing Multimetal oxide.
Concrete application method：Garnet micropowder is added in epoxy resin as filler, auxiliary agent is added, is obtained epoxy
Resin A component, epoxy resin component A are mixed with firming agent again, prepare epoxyn；Wherein garnet micropowder plus
Enter that amount accounts for epoxy resin quality 1.5-2.5 times.
A kind of epoxyn, concrete component and proportioning are：Epoxy resin component A is with firming agent according to mass ratio
For 100：15-25 is constituted, and the epoxy resin component A is：Epoxy resin with auxiliary agent, garnet micropowder according to mass ratio is
30-40：1-2：60-80 is constituted；Wherein garnet micropowder is as described in one of claim 1-3.
Preferred concrete component and proportioning are：Epoxy resin component A and firming agent are 100 according to mass ratio：20 compositions,
The epoxy resin component A is：Epoxy resin is 36.8 with auxiliary agent, garnet micropowder according to mass ratio：1.2：62 compositions.
The auxiliary agent is preferably selected from one or more in dispersant, defoamer, levelling agent, antiager.The auxiliary agent
All it is existing product with firming agent, selects as needed to add, be not the emphasis of the application.Epoxy resin used and firming agent
The conventional epoxy and firming agent for doing adhesive is, epoxy resin can be epoxy resin E51, E44 etc..
Compared with prior art, advantage of the invention is that:
1st, garnet is reclaimed in mine tailing, reduce tailings discharging amount, reclaimed resource.
2nd, garnet mineral are reclaimed using gravity treatment-magnetic separation-grading technology, reduces product cost, technique adapts to wide.
3rd, due to the distinctive chemical inertness of garnet mineral and high rigidity, epoxyn hardness and wear-resisting is improved
Performance, reduces shrinkage factor, especially makees road surface and strengthens high-abrasive material application, plays road surface and strengthens reinforcing with large development future.
4th, during garnet micropowder is as applying filler epoxyn, loading can reach more than 60%, institute
The epoxyn performance of preparation reaches GB50367-2006《Concrete structure reinforcement design specification》Middle adhesive and mixed
Solidifying soil patching material index, with wear-resisting, resistance to compression, corrosion resistance is improved, reduces material cost.
