Abstract
The present invention discloses one kind of polishing tool of glass fiber leftover and its material recipe and making process. The recipe consists of glass fiber 20-50 wt%, abrasive 20-50 wt%, and phenolic resin 10-30 wt%. The making process includes the following steps: screening glass fiber leftover to eliminate impurity, mixing abrasive and partial phenolic resin, mixing the mixed abrasive and partial phenolic resin with the rest phenolic resin mechanically to form agglomerate, weighing and pressing to form inside some mold, cooling and demolding, cutting and trimming. The polishing tool of waste glass fiber may be used in polishing field with oil stain and water stain and may result in unforeseen effect.
Description
Technical field
The present invention relates to prescription of a kind of grinding tool and preparation method thereof, relate in particular to prescription that utilizes the polishing abrasive tool that glass fiber leftover material makes and preparation method thereof, prepared solid piece, both can directly be used as the grinding tool product uses, also can do squarely, circle or abnormity and stick on the squares such as glass fibre, become polishing abrasive tool and in all kinds of instruments, use.
Background technology
Glass fibre and goods thereof can produce some scrap stock in process of production to some extent, and the main component of these scrap stock is glass fibre, and they can not be degraded, and some also contains different types of resin, and long-term the placement can produce spontaneous combustion.Owing to can't be fully utilized, these scrap stock can only be used as the industrial refuse processing, become a kind of environmental pollutant that can't degrade.600,000 tons of glass fibre output with China in 2005 can produce 5% scrap stock meter, just will produce about 30,000 tons environmental pollutant.This has not only wasted raw material, has increased production cost, also environment is produced very adverse influence.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of prescription that utilizes the polishing abrasive tool that glass fiber leftover material makes and preparation method thereof, glass fiber leftover material can be made full use of, and reduces the pollution to environment.
The technical scheme that the present invention solves the problems of the technologies described above is, adopt a kind of prescription that utilizes the polishing abrasive tool that glass fiber leftover material makes, main ingredient in this prescription and weight proportion thereof are: glass fibre 20%-50%, abrasive material 20%-50%, resol 10%-30%.
In order to reach better effect, also comprise the auxiliary agent of 5%-15% weight ratio in this prescription.Described auxiliary agent comprises: lime carbonate 1%-10%, toner 1%-5%, rubber powder 1%-5%.
Described abrasive material adopts at least a in brown corundum, silicon carbide or the zirconium white.
Described resol is made up of the powdered phenol-formaldehyde resin of 10%-20% and the liquid phenolic resin of 10%-20%.
The making method of above-mentioned polishing abrasive tool comprises the steps:
1) impurity is removed in the glass fiber leftover material screening, weighed on demand;
2) quantitative abrasive material and part resol is evenly mixed;
3), form elementary material group with the glass fiber leftover material that takes by weighing in the step 1) and the uniform mixing of mixed good abrasive material machinery;
4) in elementary material group, add remaining resol, stir and form material group;
5) with above-mentioned steps 4) in material group put into mould after weighing;
6) mould is placed on extrusion forming on the press bed, in case of necessity, suitably venting in the pressure process;
7) after the moulding, the demoulding to be cooled, and by service requirements cutting finishing polishing abrasive tool.
Also add the auxiliary agent of prescription gross weight 5%-15% in the described step 3), comprising: lime carbonate, toner and rubber powder.
Described resol is made up of powdered phenol-formaldehyde resin and liquid phenolic resin, and the weight ratio of powdered phenol-formaldehyde resin and liquid phenolic resin is 1: 2.5 to 2: 3; Described step 2) stirs abrasive material with the 15-30% in the liquid phenolic resin earlier in it is fully soaked into, mix and stir with all powdered phenol-formaldehyde resins again; Add remaining liquid phenolic resin in the step 4) elementary material is rolled into a ball bonding one-tenth material group.
In the described step 1), also with glass fiber leftover material by cut control its length within 300 millimeters, and control its moisture content glass fiber leftover material weight 3% in.
Extrusion forming was set under 185 ± 5 degrees centigrade, 20-150Mpa condition 20-140 minute in the described step 6).
Compare with prior art, the polishing abrasive tool with prescription of the present invention and method are made makes full use of the depleted glass fiber leftover material, has both saved the raw material and the energy, has protected environment again, and its society and economic implications all are very huge; In addition, grinding tool of the present invention can be used for the occasion of all kinds of polishings, because the irregular distribution of scrap stock has the effect of skeleton, and self can emit gas during an amount of resol cure under pressure, make grinding tool have the perforate of connection, just because of the existence of this perforate, making is having greasy dirt and water stain polishing occasion, polishing wheel can not stuck with paste the hole, can not injure and be thrown workpiece, compare, have beyond thought effect with other grinding tools; The solid piece that the present invention makes is both used directly to be used as the grinding tool product, also can do squarely, circle or abnormity and stick on the square such as glass fibre, becomes polishing abrasive tool and cooperates electricity (gas) tool of starting building to use.
