Abstract

The invention discloses a kind of preparation method of Foamex emery wheel, can prepare it is light, it is nontoxic, it is cost-effective, and be better than the Foamex emery wheel of ordinary resin emery wheel in water resistance, anti-wear performance, heat conductivility etc..Method includes：S1, modified silicon carbide filler preparation；S2, Foamex emery wheel preparation.Then mould is put into foamed, solidification, the demoulding in baking oven and obtains Foamex emery wheel.

Description

The preparation method of Foamex emery wheel
Technical field
The invention belongs to casting technology field, and in particular to a kind of preparation method of Foamex emery wheel.
Background technology
The lightweight resin wheel that the country uses, is mainly combined with abrasive material as bonding agent using polyvinyl alcohol and resin wheel is made, It is wherein of greatest concern with polyvinyl acetal resin emery wheel.The resin wheel has a spongy micropore, is not easily blocked during grinding micro- Hole, and there is certain elasticity and hardness, polishing effect is good.But there is the shortcomings that certain in it, such as：Polishing cycle is short, low intensity, Abrasion abrasion is big, and preparation process Poisoning is big, and harm to the human body is big.
The content of the invention
In order to overcome above mentioned problem existing for prior art, it is an object of the present invention to provide a kind of Foamex The preparation method of emery wheel, this method is easily operated, and the emery wheel of preparation is light, nontoxic, cost-effective, and in water resistance, it is wear-resisting Performance, heat conductivility etc. is better than ordinary resin emery wheel.
The preparation method of Foamex emery wheel provided by the invention, comprises the following steps：
(1) preparation of modified silicon carbide filler：Silane coupler is well mixed in a reservoir with absolute ethyl alcohol, adds carborundum Micro mist, in stirred in water bath, uniformly rear drying is modified silicon carbide filler；
(2) preparation of Foamex emery wheel：Epoxy resin, solvent are added in container and stirred at 60-80 DEG C of bath temperature Uniformly, modified silicon carbide filler is added, surfactant is instilled, stirs, silane coupler is with absolute ethyl alcohol according to specific Mass ratio is well mixed in a reservoir, and extra fine quality proportion is 2: 97-5: 94；
(3) foaming agent, blowing promotor, curing agent component A are sequentially added, the particle mean size of modified silicon carbide filler is 7-12 μm, Under agitation, add curing agent B component, after stirring inject mould in, then by mould be put into baking oven it is foamed, Solidification, the demoulding obtain Foamex emery wheel.
The preparation method of Foamex emery wheel provided by the invention, its advantage are：By micro- to abrasive material carborundum Powder is modified so as to improve the surface state of silicon carbide powder, reduces surface-active, improves dispersiveness and solid concentration and powder The mobility of body；Utilize epoxy resin, solvent, modified silicon carbide filler, surfactant, foaming agent, blowing promotor, curing agent Prepare Foamex emery wheel.The wheel strength of this bonding agent manufacture is high, has certain elasticity, thermal conductivity is high, self-sharpening Good, simple for production, process cycle is short.
Embodiment
With reference to embodiment, to the preparation method of Foamex emery wheel provided by the invention, it is described in detail.
Embodiment
The preparation method of the Foamex emery wheel of the present embodiment, comprises the following steps：
(1) preparation of modified silicon carbide filler：Silane coupler is well mixed in a reservoir with absolute ethyl alcohol, adds carborundum Micro mist, in stirred in water bath, uniformly rear drying is modified silicon carbide filler；
(2) preparation of Foamex emery wheel：Epoxy resin, solvent are added in container stirred at 60 DEG C of bath temperature it is equal It is even, modified silicon carbide filler is added, surfactant is instilled, stirs, silane coupler is with absolute ethyl alcohol according to specific matter Amount ratio is well mixed in a reservoir, and extra fine quality ratio is 5: 94；
(3) foaming agent, blowing promotor, curing agent component A are sequentially added, the particle mean size of modified silicon carbide filler is 12 μm, Under stirring condition, curing agent B component is added, is injected after stirring in mould, is then put into mould foamed, solid in baking oven Change, the demoulding obtains Foamex emery wheel.
