Abstract
A kind of nylon glass polishing disk and manufacture method thereof, it is characterized in that, this polishing disk raw material includes abrasive particle, filler, caprolactam monomer, catalyst, promoter composition, described abrasive particle is alumina-cerium oxide core shell composite grain, and described filler includes heat filling, active filler, water solublity pore creating material composition.It is an advantage of the current invention that: 1, grinding tool porosity is big, it is simple to hold bits；2, the temperature low workpiece that is not result in grinding area bursts；3, bonding agent wearability is high, grinding tool long service life.
Description
Technical field
The invention belongs to glass polishing field, be specifically related to MC nylon glass polishing disk and manufacture method thereof.
Background technology
Polishing disk is to process requisite polishing tool for high-grade glass artware, polishing disk used is mostly the rare earth cerium oxide polishing disk as grinding abrasive particle, China Patent Publication No. is CN102114615A, although the stock-removing efficiency solving conventional polishing disk is low, surface smoothness is not high, the shortcomings such as polishing time is long, inefficiency, but rare earth big bulge in price so that a lot of polishing enterprises lose in a large number.China Patent Publication No. has been the patent disclosure of CN102120315A adopts modified diamond as the polishing disk of abrasive particle, although service life (wearability) is about rare earth polishing disc twice, but diamond is more expensive than rare earth, and cost is too high.Glass polishing disk that China Patent No. has been the patent disclosure of 201110231332.7 with alumina-cerium oxide core shell composite grain for grinding abrasive particle and manufacture method thereof, owing to the Compostie abrasive particles adopted both had had α-Al2O3Heavy-duty grinding power, have again cerium rouge chemical mechanical polishing mechanism fast polishing performance, and due to containing Ce3+Cerium oxide soft shell, decrease the cut to glass polishing face, polishing flatness is high, and fineness is good.But the unsaturated-resin that its bonding agent adopts, grinding tool is harder, and the wearability of bonding agent own is poor so that the service life of grinding tool is affected.
Summary of the invention
A kind of stock-removing efficiency that the purpose of the present invention provides for problem existing in above-mentioned prior art just is high, wearability is good, long service life, surface smoothness are high MC nylon glass polishing disk and manufacture method thereof.
It is an object of the invention to be achieved through the following technical solutions:
The glass polishing disk raw material of the present invention includes abrasive particle, filler, caprolactam monomer, catalyst, promoter composition, the percentage by weight of each raw material is: abrasive particle 20%～40%, filler 5%～15%, caprolactam monomer 55%～70%, catalyst 0.5%～1%, promoter 0.5%～1%；Described abrasive particle is alumina-cerium oxide core shell composite grain, and described filler includes heat filling, active filler, water solublity pore creating material.
Described heat filling is one or more combinations in graphite, aluminium nitride, CNT, and heat filling has superpower heat conductivility, can derive the heat that grinding area produces in time, it is to avoid temperature too high generation in grinding area bursts phenomenon.Graphite in heat filling plays again the effect of kollag, and the addition of CNT makes grinding tool intensity improve, and wearability increases, and can reduce the roughness of glass surface, increases fineness.
Described active filler is one or both combinations in sodium fluoride, ammonium fluoride, and fluoride can have chemical polishing effect with glass chemically reactive.
Described water solublity pore creating material is white sugar, white sugar good water solubility, is dissolved in water and forms space at polishing contact surface, have appearance bits function on the one hand, can absorb the temperature of grinding points on the other hand, have cooling function during polishing.
The catalyst that described catalyst is conventional when being caprolactam monomer polymerization, the alkaline matter such as Na, NaOH that the patent of invention (publication number: CN102181149A) such as Wen Shaoguo is reported, it is preferred to NaOH.
The promoter that described promoter is conventional when being caprolactam monomer polymerization, TDI, MDI, DPI that the patent of invention (publication number: CN102181149A) such as Wen Shaoguo is reported, it is preferred to TDI.
The particle diameter of described alumina-cerium oxide core shell composite grain is 0.05-5 μm, the method that the patent of invention (publication number: CN201110231333.1) of preparation method such as Chen Jinshen is reported.
The manufacture method of the glass polishing disk of the present invention specifically comprises the following steps that
A, caprolactam monomer adding heat fusing, add abrasive particle and filler, powerful mechanical agitation, ultrasonic disperse is sufficiently mixed；
B, in vacuum more than at 0.1MPa and temperature 130 DEG C, evacuation dehydration is complete, adds catalyst, mixing；
C, continuation evacuation dehydration completely, release vacuum, add promoter, stir；
D, it is cast in the mould of preheating, centrifugal casting reaction 20min, naturally cool to room temperature, the demoulding, namely obtain monomer casting MC nylon glass polishing disk.
During application, the glass polishing mill double-component gluing being cured on iron pan, it is arranged on buffing machine.
It is an advantage of the current invention that: 1, grinding tool porosity is big, it is simple to hold bits；2, glossiness improves speed soon, and the gloss persistent period is long, and the low workpiece that is not result in of grinding temperature breaks simultaneously；3, bonding agent wearability is high, grinding tool long service life.
