At present in jewellery polishing process, multiplex PL resin (polyimide resin) carries out polishing in conjunction with abrading block, but common polyimide resin is large in conjunction with the rigidity of abrading block, not easily processes the precious metal ornaments of quality softness.Therefore provide that a kind of self-sharpening is good, the noble metal polishing abrading block of good toughness is very important.
Summary of the invention
Object of the present invention is to provide that a kind of self-sharpening is good, the jewellery polishing abrading block of good toughness and preparation method thereof.
For achieving the above object, the technical scheme that the present invention takes is, a kind of jewellery polishing abrading block, is made up of the raw material of following portions by weight: Lauxite 30 ~ 70 parts, corundum powder 30 ~ 70 parts, aldehydes smoke agent for shielding 0.5 ~ 1.5,5 ~ 15 parts, curing agent, colouring agent 0.5 ~ 3.5 part.
Described jewellery polishing abrading block, comprises the following steps: after corundum powder and colouring agent mixing, load ball mill and grind, grind 3 ~ 5 hours, obtain inserts; By Lauxite, inserts and aldehydes smoke agent for shielding, mixing, stirs and obtains slip; Slip is added curing agent, adds in mould after stirring, ambient temperature curing; By the product demoulding after solidification, be placed in 80 ~ 100 DEG C of insulating box water-baths, water bath time is 3 ~ 5 hours; Product after water-bath is dried at 40 ~ 60 DEG C; Product after drying is carried out surperficial shaping, gets product.
Preferably, described colouring agent is carmine.
The present invention adopts Lauxite to be bonding agent, is equipped with aluminium active filler, forms through normal temperature cure, and the jewellery polishing abrading block self-sharpening prepared is good, good toughness, and the jewellery unharmful substance after polishing remains.
Detailed description of the invention
