Abstract
A soft abrasive wheel (or adrasive disk) is prepared from polyurethane rubber as adhesive, diamond particles with different granularities, and gypsum powder as filler. It has high polishing efficiency up to 7% and high grinding efficiency up to 30%.
Description
Technical field:
A kind of polyurethane glue software Grinding wheel disc mill.
Background technology:
Present software mold glue, as natural prevulcanized latex, resistant to elevated temperatures silica gel, chloroprene rubber etc. can be as the software mold glues, polyurethane material glue has been used in the inside " to reinforce the water blockoff polyurethane material " in the Chinese patent file 85103075, " visco-elasticity polyamine fat seal gum is manufacturing process extremely " also used the polyurethane material bipeltate in the application number 92113420, the present invention has any different with them on prescription, and is also different in the use field.
Technology contents:
The prescription and the preparation method that the purpose of this invention is to provide the software Grinding wheel disc mill, the elasticity acid and alkali-resistance of polyurethane glue, aspect such as water-fast, oil resistant all has one's own knack.
Technical scheme of the present invention is: add ferric oxide 20 grams in 360 gram performed polymers (T830), 120 gram polyether resins, many many phenyl of the methyl polyisocyanates of 120 grams, 4 gram dimethylbenzene, terra alba 300 grams, after 46-1000 silicon carbide 150 grams are mixed evenly, adding promotor, toughener etc.
The included weight proportion of the present invention is:
Performed polymer (T830) 360 grams
Many many phenyl of methyl polyisocyanates 120 grams
Polyether resin 120 grams
Ferric oxide 20 grams
Terra alba 300 grams
Silicon carbide 46-1000 150-300 gram
Triethylamine (reagent) 0.8 gram
Dibutyl tin laurate 0.4 gram
Frothing medicine 4 grams
Dimethylbenzene 4 grams
Dibutyl phthalate (DBP) 4 grams
Making method is: performed polymer (T830), ferric oxide, terra alba, silicon carbide, dimethylbenzene with metering in mixer stir evenly, after stirring, can make the polyurethane glue of software Grinding wheel disc mill, add the silicon carbide of various granularities then as required, after stirring, be cast in the mould of different shape, mould needs the brush releasing agent before mould material, tie up the abrasive band if be coated with, can brush polyurethane glue on cloth earlier, spray to go up particles of silicon carbide then, can become abrasive band or emery cloth etc. and be coated with and tie up mould.
Specific embodiments:
The mixed slurry of preparation 1000 grams, in agitator with 360 the gram performed polymers (T830), 300 gram terra albas, many many phenyl of the methyl polyisocyanates of 120 grams, 120 gram polyether resins, 150 gram silicon carbide heated and stirred are even, can cool off barrelling, triethylamine 0.8 gram as promotor, dibutyl tin laurate 0.4 gram, frothing medicine 4 grams, also have to produce dibutyl phthalate (DBP) 0.4 gram of dilution and plastification should be earlier and dimethylbenzene 0.4 restrain and dissolve, the mixture of this different materials is added in performed polymer and the resin that is mixed, go in the materials such as terra alba, prepare polyurethane glue, just prepare the silicon carbide of how many granularities as the emery wheel of how many granularities of needs, be cast in then in the metal die of various size and specification, tie up in the mould if be coated with, can brush glue on cloth or other yarn fabric last 5 hour of after drying moulding, before the cast, if metal die must be brushed polyvinyl alcohol liquid on mould, machine oil and paraffin etc.This is not to be bonded on the mould during for the form removal tool.
