Description
Technical field
The present invention relates to a kind of abrasive band, specifically Zirconium corundum heavy load strong abrasive band.
Background technology
The high speed development of mechanical industry, more and more higher to the requirement of coated abrasive tool product, consumption is also increasing.In the grinding of hardware surface-treated, to also having been proposed many-sided requirement by the grinding of buffing work-piece.
The country of Asia mechanical industry prosperities such as Japan, Korea S, developed in recent years under heavy load conditions to metal component surface roughly grind, the strong abrasive band of middle mill, be called heavy load strong abrasive band.External this heavy load strong abrasive band has captured the market, whole Asia that comprises China in one time.At present, the complete dependence on import of high-quality heavy load strong abrasive band of domestic mechanical industry use.
The abrasive band product is made up of three parts: fabricbase, adhesive, removing material, removing material is bonded on the fabricbase by adhesive.At present, the adhesive of heavy load strong abrasive band is mixed by phenolic resins, dispersant, emulsifying agent, diluent etc. on the domestic market, its major defect has: 1. heat resistance is low: in the heavy load grinding process, the short time produces high temperature between grinding tool and the hardware, and the high temperature that moment produces in the grinding can make the scorch (distortion or variable color) of grinding workpiece.2. the adhesive strength under the condition of high temperature is low, in the heavy load grinding process, the short time produces high temperature between grinding tool and the hardware, the adhesive that heat resistance is low changes, control the ability wretched insufficiency of abrasive material, sand grains comes off and loses grinding capacity, causes the ground effect of product seriously to descend, even can't satisfy the grinding requirement.Just because of the above defective of adhesive, the domestic heavy load strong abrasive band metal surface of when grinding, can burning, abrasive material easily comes off, and grinding efficiency is lower, and service life is shorter.
Summary of the invention
The objective of the invention is to propose a kind of can fast softening when grinding and reduce metal skin hardness, the metal surface of neither can burning can greatly improve the Zirconium corundum heavy load strong abrasive band of grinding efficiency again.
Purpose of the present invention can be achieved through the following technical solutions:
Zirconium corundum heavy load strong abrasive band is made up of fabricbase, adhesive, removing material, and removing material is a fused alumina zirconia, and removing material is bonded on the fabricbase by adhesive, and adhesive is made up of following components in weight percentage:
Single order thermosetting phenolic resin 28%～36%
Propane type epoxy resin of di phenolic group 4%～8%
Melmac 1%～4%
Boron 0.2%～0.6%
Dispersant 0.1%～0.3%
Coupling agent 0.1%～0.3%
Diluent 3%～6%
Fluoride salt 45%～60%
Inert gas fluoride 0.5%～1%.
Purpose of the present invention can also further realize by following technical measures:
Aforesaid Zirconium corundum heavy load strong abrasive band, wherein said dispersant is the sorbitol monostearate that anhydrates (SPAN-60), polyoxyethylene anhydrate sorbitol monostearate (Tween-60), polyglycerol ester.
Aforesaid Zirconium corundum heavy load strong abrasive band, wherein said coupling agent is: silane coupler, titanate coupling agent, aluminate coupling agent.
Aforesaid Zirconium corundum heavy load strong abrasive band, wherein said diluent are ethylene glycol ethyl ether, methyl alcohol, ethanol, distilled water.
Aforesaid Zirconium corundum heavy load strong abrasive band, wherein said fluoride salt are cryolite, sodium fluoborate, calcirm-fluoride, sodium fluoride, aluminum fluoride.
Aforesaid Zirconium corundum heavy load strong abrasive band, wherein said inert gas fluoride are xenon difluoride (XeF2), xenon tetrafluoride (XeF4), xenon hexafluoride (XeF6).
Advantage of the present invention is: add single order thermosetting phenolic resin and propane type epoxy resin of di phenolic group and melmac in the adhesive of Zirconium corundum heavy load strong abrasive band of the present invention, can have the advantage of three kinds of resins concurrently, improve their shortcomings separately, reach the purpose of modification, make adhesive have the resistance to water of good caking property of epoxy resin and melmac, improved the fragility of phenolic resins, keep the good hear resistance of phenolic resins simultaneously, overcome the relatively poor shortcoming of epoxy resin hear resistance.Add boron, fluoride salt, inert gas fluoride in addition, improved the adhesive strength under the abrasive band heat resistance and the condition of high temperature, when mill was pressed temperature greater than 600 ℃, abrasive material can not come off, and when mill was pressed temperature greater than 800 ℃, adhesive can not decompose yet.Under the high temperature action of the present invention when grinding, can discharge the gaseous chemical substance that makes new advances, the energy fast softening also reduces metal skin hardness, and the metal surface of neither can burning has greatly been improved grinding efficiency again.Removing material of the present invention is selected the fused alumina zirconia of micro-crystallization, good toughness for use, and ground effect is better.
Zirconium corundum heavy load strong abrasive band of the present invention, be widely used in various hard material members such as 304#, 316# stainless steel, steel alloy, alumin(i)um zinc alloy, ormolu corase grind, the middle mill field of (containing the mill cast member), its grinding efficiency is more than 5 times of common abrasive band, and the consumption in abrasive band has reduced by 20% than common abrasive band, grinding workpiece surface exhausted nothing burn phenomenon, improve operating efficiency, product quality significantly, reduced cost.
The tensile strength of Zirconium corundum heavy load strong abrasive band of the present invention and longitudinal tensile strain rate such as table 1 are as showing:
Table 1
| Base material | Tensile strength (KN/m) | Longitudinal tensile strain rate under the web-like 600N load |
| Vertically | Laterally | ％ | |
| H | ≧76 | ≧24 | ≦2 |
As shown in Table 1, heavy load strong abrasive band of the present invention, its tensile strength is improved.
The dynamic grinding performance index of Zirconium corundum heavy load strong abrasive band of the present invention is as shown in table 2,
Table 2
As shown in Table 2, Zirconium corundum heavy load strong abrasive band of the present invention, its demetalization amount is higher, and service life is longer, and grinding pressure has had raising, and common sbrasive belt grinding pressure is 80～120N.
