Description
Technical field
The invention belongs to finishing technical fields, and in particular to it is a kind of for workpiece material grinding resin wheel and its
Preparation method.
Background technique
Urea-resion adhesive market demand is maximum, and since its raw material is cheap and easy to get, manufacturing process is simple, is widely applied
It is processed in woodenware, the industries such as artificial board production and interior decoration.But it is never paid close attention to by people for polishing grinding grinding wheel
With use, people are using always vitrified abrasive grinding-polishing for these years, but vitrified abrasive abrasive grain is thick, bonding agent solidification
Time is long, solidification temperature is high, and fever is big when polishing uses, and is easy burn and scratches workpiece, people are always ceramic sand crop rotation
For grinding roughing come using.As the demand of market high-precision polishing needs how many researchers to start with phenolic resin, ring
Oxygen resin, unsaturated-resin etc. manufacture grinding wheel, but resin wheel price in the market is more expensive, and most of cutting force are good
It is good, and polishing effect is unable to reach high surface roughness (finish) always, also there is various antiscuffing paste and polishing in the market
Cloth etc., but those products can only dry tumbling, air pollution is big, and wet environment is not available.
The pollopas that present invention urea and formaldehyde synthetic reaction generate, then changed with melamine and polyvinyl alcohol
Property, the pollopas more flexible after being modified also greatly improves its wearability.Abrasive material selects silicon carbide micro-powder, surpasses
Thin abrasive grain substantially increases workpiece product class in terms of grinding and polishing.This product does not appoint dry grinding or wet process
Grinding is ok, and is not influenced by grinding environment.It is precious along with expansion cheap and easy to get is used since pollopas is cheap
Pearl rock powder end and starch material, production are low in cost.Production equipment is simple simultaneously, does not need that large-scale machinery put into
Equipment, product curing time is short, and curing apparatus uses box barbecue, and barbecue device is cheap, before having extraordinary industrial application
Scape.
Summary of the invention
The purpose of the present invention is to provide a kind of resin wheels for workpiece material grinding.By changing to pollopas
Property, it is combined with silicon carbide micro-powder and other fillers, resin wheel is made by sectional temperature-controlled curing method, is greatly mentioned
The wearability and heat resistance of high product are suitable for various workpieces and grind, and are not influenced by grinding environment, and cost of material is low, prepares work
Skill is simple.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of resin wheel for workpiece material grinding, is prepared from the following raw materials: pollopas, melamine, poly- second
Enol, ammonium chloride, oxalic acid, silicon carbide, expanded perlite and starch.
Wherein pollopas, melamine, polyvinyl alcohol, ammonium chloride, oxalic acid be in mass ratio 100:2 ~ 5:5 ~ 10:1.5 ~
2.5:1~2；Pollopas and silicon carbide mass ratio are 0.9 ~ 2.3:1；Silicon carbide, expanded perlite and starch are 1 in mass ratio:
0.005~0.03:0.01~0.08。
Wherein pollopas is with urea and volume fraction 36.5%--37.5% formalin, in molar ratio 1:1.5 addition
Amount uses sodium hydroxide 1wt% aqueous solution to synthesize as catalyst.
The preparation method of the resin wheel for workpiece material grinding, specific steps are as follows:
(1) pollopas is prepared, melamine then is added according to the proportion and 10% polyvinyl alcohol of volume fraction is changed
Property；
(2) ammonium chloride, oxalic acid, silicon carbide, expanded perlite and starch mixing are added according to the ratio to step (1) product to stir
It mixes；
(3) defoaming, then moulding by casting, baking and curing then are vacuumized to step (2) product, cooling obtains grinding wheel product.
Wherein cure stage temperature regulate and control are as follows: 80 DEG C 3 hours → 100 DEG C 2 hours → 120 DEG C 2 hours → 150 DEG C 5 hours
→ 160 DEG C 2 hours → 140 DEG C 1 hour → 120 DEG C 1 hour → 100 DEG C 1 hour → 80 DEG C 1 hour → shutdown terminate.Naturally cold
It comes out of the stove when but to 50 DEG C or less.
Remarkable advantage of the invention is:
(1) pollopas used in the present invention is had good wearability by modified tool, and with excellent toughness and
Heat resistance, as adhesive, so that the durability of resin wheel greatly improves；Sand is enhanced by addition silicon carbide simultaneously
Hardness to be taken turns, improves the physicochemical property of material by addition expanded perlite and starch, especially expanded perlite hole is larger,
It is easy to radiate, improves the thermal diffusivity of resin wheel；And the compounding of overall composition is so that the material of resin wheel is wear-resisting in presentation
Had both again " in hard material " " softwood matter ", grinding wheel obtained especially suitable for polish workpiece surface.
(2) inventive article can be with the various workpiece materials of grinding and polishing such as: metal, glass, stone material, precision instruments, timber,
The all surfaces such as jewelry, plastics, lacquerware need last procedure grinding of high roughness (finish), make workpiece material surface
Roughness (finish) reaches mirror effect, and workpiece material surface roughness < 0.1 micron after processing meets or exceeds country
The surface roughness of standard GB3505-83 and GB1031-83 highest level provides；Product of the present invention energy continuous work, finishing time
Number is few, not modify substantially, the working time is greatly saved, improve work efficiency.
(3) since the present invention is moulding by casting, the different products at shape can be produced at shape according to different molds, it can
With the workpiece material grinding and polishing for different field.
Specific embodiment
Further to disclose rather than the present invention is limited, the present invention is described in further detail below in conjunction with example.
The preparation method of the resin wheel for workpiece material grinding, specific steps are as follows:
(1) pollopas is prepared, melamine then is added according to the proportion and 10% polyvinyl alcohol of volume fraction is changed
