Description
Technical field
The invention belongs to emery wheel technical field, more particularly to a kind of deep viscosity mixed coating corundum abrasive.
Background technology
Abrasive material is sharp keen, hard material, to be ground softer material surface.Abrasive material has natural abrasive and manufactured abrasive
Two major classes.According to hardness classification has super hard abrasive and commonly wastes the major class of abrasive material two.The scope of abrasive material is very wide, from softer family expenses de-sludging
Agent, jewel abrasive material to most hard material diamond.
Abrasive material is the manufacture essential material of each sophisticated product.One of important performance of abrasive material is the hard of it
Degree, it must be harder than material to be processed, commonly uses the hardness that Moh's hardness scale determines various abrasive materials.Another important performance of abrasive material
It is toughness or bulk strength.Can combined amount, purity, granularity and the crystal structure etc. of feed change control this performance, with suitable
Together in various applications.Abrasive material is the granular material that shear action is played in grinding, grinding and polishing.Abrasive material mainly for the manufacture of
Grinding tool, some grindings and polishing can also be directly used in.
Abrasive material should have following fundamental property：1. higher hardness, typically should be higher than that machined material；2. appropriate is strong
Degree, cutting force can be born when abrasive particle cutting blade is also sharp without fragmentation, when cutting blade blunt to a certain extent when can local chips and
Expose new keen edge；3. high-temperature stability, its intrinsic hardness and intensity can be kept under grinding temperature；It is 4. chemical lazy
Property, it is not likely to produce chemical reaction with machined material.These properties and the chemical composition of abrasive material, mineral composition, crystal habit and
The integrated degree of crystal etc. is relevant.
Emery wheel is a kind of instrument that use range is relatively broad in grinding tool, because emery wheel is contorted in high speed when in use
State is, it is necessary to bear larger impulsive force, therefore, the property such as heat generation during to the grinding efficiency of emery wheel, toughness, self-sharpening, grinding
Can there is higher requirement.
Can reduce the durability of emery wheel if abrasive material viscosity of the prior art is inadequate, hardness and fragility it is not high enough if,
The sharp effect of product can be influenceed.
The content of the invention
In order to solve the above problems, the present invention provides a kind of deep viscosity mixed coating corundum abrasive.
The technical solution adopted by the present invention is：
A kind of deep viscosity mixed coating corundum abrasive, described deep viscosity mixed coating corundum abrasive are made up of following ingredients
's：Major ingredient includes：White fused alumina, Brown Alundum, auxiliary material include：Corn Starch, fused alumina zirconia powder, kaolin and water.
In described major ingredient：The weight of white fused alumina accounts for the 40%-80% of major ingredient gross weight, and the weight of Brown Alundum accounts for major ingredient gross weight
The 20%-60% of amount.
The addition of described Corn Starch accounts for the 1%-1.5% of major ingredient gross weight, and the addition of fused alumina zirconia powder accounts for master
Expect the 5%-8% of gross weight, kaolinic addition accounts for the 12%-18% of major ingredient gross weight, and the addition of water accounts for major ingredient gross weight
5%-6%。
The granularity of described Corn Starch was 325 mesh sieves, and the fineness of fused alumina zirconia powder was 800 mesh sieves.
The beneficial effects of the invention are as follows：The application is added with Corn Starch and kaolin, Corn Starch and height
The higher fused alumina zirconia powder of toughness is simultaneously firmly sticky on the brown abrasive material top layer mixed in vain by ridge local products life fusion, is had sharp and resistance to
Characteristic；The corundum top layer treated by high-temperature calcination possesses clay irregular surface, can tie ordinary resin glue etc.
Stronger the allowing of mixture is plated to be bonded between each other according to corundum, strengthens the durability of emery wheel；Face coat hardness and fragility are very high
Fused alumina zirconia powder, this can allow abrasive material top layer to have thermal diffusivity initial contact with cut substrate, improve the sharp effect of product.
