Abstract
The invention provides a wear-resistant screen rubber material for oredressing. The wear-resistant screen rubber material is prepared from the following raw materials: at least one of natural rubber, styrene butadiene rubber and butadiene rubber, zinc oxide, stearic acid, a rubber protective agent, a wear-resistant reinforcing agent, magnetic powder, a softening agent, an accelerator and sulfur. The rubber material is mainly applied to mining wear-resistant rubber screens, and can obviously improve wear resistance to prolong the service life of the mining rubber screens.
Description
[technical field]
The present invention relates to a kind of preparation equipment, relate in particular to a kind of ore dressing abrasion-proof screen sizing material.
[background technology]
Along with the development of mining processing industry and the raising of technique of preparing, but cause the quality of ore dressing more and more lower.In order to improve output, the ore dressing amount must increase, and certainly will cause like this requiring more and more higher to the wear resistance of screen cloth sizing material, should have more wear resistance, though but present Rubber screen has possessed wear resistance preferably, for the ore dressing industry, its wear resistance still remains further to be improved.
[summary of the invention]
The technical problem to be solved in the present invention is to provide a kind of ore dressing abrasion-proof screen sizing material, by adding the magnetic powder, makes sizing material have magnetic, forms a protective layer, makes wear resistance better can adsorb powdered iron ore or iron powder in ore-dressing practice.
The present invention is achieved in that a kind of ore dressing abrasion-proof screen sizing material, it is characterized in that: described sizing material is formulated by weight by following raw material:
At least a 100 of natural rubber or styrene-butadiene rubber(SBR) or cis-1,4-polybutadiene rubber;
Zinc oxide 5;
Stearic acid 2;
Rubber protecting agent 2～5;
Wear-resisting strengthening agent 50～75;
Magnetic powder 10～500;
Tenderizer 5～10;
Promotor 1～2;
Sulphur 2～3.
The present invention has following advantage: by add a certain proportion of magnetic powder in the abrasion-proof screen sizing material, make sizing material have magnetic, so, in ore-dressing practice, the abrasion-proof screen sizing material can adsorb powdered iron ore or iron powder (as the powder of benficiation machinery equipment attrition) thereby form a protective layer, makes ore can't directly sting the surface of cutting scratching abrasion-proof screen sizing material on the sizing material surface, makes wear resistance better; The powdered iron ore particulate makes out-of-date phorogenesis of trommel simultaneously, reduces the resistance that passes through, to improve beneficiating efficiency.
[embodiment]
One, raw material is prepared: with following raw material by weight weighing:
At least a 100 of natural rubber or styrene-butadiene rubber(SBR) or cis-1,4-polybutadiene rubber;
Zinc oxide 5;
Stearic acid 2;
Rubber protecting agent 2～5;
Wear-resisting strengthening agent 50～75;
Magnetic powder 10～500;
Tenderizer 5～10;
Promotor 1～2;
Sulphur 2～3.
Two, it is mixing to take following technology to carry out above-mentioned load weighted raw material:
1, little compatibility test sizing material
Raw material is placed on carries out mixingly in the XK-160 mill, order of addition(of ingredients) is:
At least a-zinc oxide-stearic acid-the rubber protecting agent of natural rubber, styrene-butadiene rubber(SBR), cis-1,4-polybutadiene rubber, wear-resisting strengthening agent, magnetic powder-tenderizer and promotor-sulphur.
2, produce sizing material technology
Raw material is placed on carries out mixingly on the XN-55 milling machine, and adopt the two-stage mixing method, comprise one section mixing and two-stage mixing.
Described one section mixing order of addition(of ingredients) is:
At least a-zinc oxide-the stearic acid of natural rubber, styrene-butadiene rubber(SBR), cis-1,4-polybutadiene rubber, the wear-resisting strengthening agent of rubber protecting agent-2/3rds, magnetic powder-tenderizer;
Carry out binder removal after mixing, dump temperature is controlled at 120 ± 10 ℃, afterwards slice again.
Described two-stage mixing order of addition(of ingredients) is: the wear-resisting strengthening agent of one section rubber master batch-promotor, residue 1/3rd;
Carry out binder removal after mixing, dump temperature is controlled at 100 ± 10 ℃, adds the sulphur slice afterwards again.
Three, performance test data table
Use the data of the two performance test gained of sizing material of the sizing material of prescription of the present invention (at producing sizing material technology) and regular convention formula (at little compatibility test sizing material) as shown in the table:
As seen from the above table, the sizing material made than regular convention formula in the prior art of the sizing material that uses prescription of the present invention to make can obviously improve wear resisting property.
The screen cloth that adopts present embodiment prescription and regular convention formula to produce sieve aperture 90 * 90 is respectively gone up at mine ore dressing equipment (disk vibration sifting machine) and is used, and uses the result to contrast as follows.
| Project | The present embodiment prescription | Regular convention formula |
| Average ore dressing amount | More than 800,000 tons | Ten thousand tons of 45-50 |
