Abstract
The invention discloses a material of a polyurethane wet type polishing wheel. The material has the advantage that the material is manufactured into the wet type polishing wheel; by utilizing the wet type polishing method, the accuracy of traditional grinding is greatly improved, the dustless or slight-dust polishing is realized, the cost of precision grinding is greatly reduced, and the material after precision grinding can be applied to multiple production fields in a large-scale way.
Description
Technical field
The invention belongs to technical field of chemical synthesis, relate to a kind of urethane composition for the production of wet type polishing wheel particularly.
Background technology
At present, known for non-ferrous metal, the polishing wheel of the grinding and polishing of carbide alloy and various nonmetallic materials is taken turns with cloth, fiber crops wheel, nylon wheel, wiring round, wind wheel, wool is taken turns, the kinds such as sponge wheel are more, in precise polished, polishing wheel is primarily of elasticity various cottons more carefully, fine felt, silk, deerskin, the material such as sisal hemp or horsehair is made, its principle utilizes the high polishing wheel of hardness ratio rapidoprint and abrasive material to produce under High Rotation Speed cut and roll, remove the micro-crude material in surface, workpiece surface roughness is caused to reduce rapidly, thus realize the function of polishing.
Generally there is poor water resistance in polishing wheel to tradition, elasticity is low, hardness is high, self-sharpening is weak, needs to carry out polishing operation in dry environments.And in operation process, a large amount of dust particle that can produce, the dust particle of generation can produce injury to the health of operating personnel, time dust runs up to a certain degree, there is the danger of dust explosion, has larger potential safety hazard.From machining accuracy aspect, easily produce the high heat of high temperature in traditional polishing process, not easily get rid of abrasive dust, easily occur filling phenomenon, cause workpiece burn to be damaged, greatly reduce Product processing yield, be difficult to the requirement using high precision polishing.
In order to solve the drawback of conventional polishing techniques, the new technologies such as magnetic grinding polishing, ultrasonic polishing, ion beam grinding and polishing are there is, although they can reach higher grinding precision, but because cost is higher, only be applied to aviation, national defence some high-end technology fields at present, still cannot large-area applications in batch production.
Summary of the invention
For overcoming the problem that traditional polishing wheel grinding precision is poor, dust is larger and Ultraprecise polished application cost is higher, invention provides a kind of urethane composition for the production of wet type polishing wheel.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A material for polyurethane wet type polishing wheel, comprises following component:
The number-average molecular weight of described polyphosphazene polymer ethoxylated polyhydric alcohol is 8500 ~ 9000, and degree of functionality is 6 ~ 6.25, and the number-average molecular weight of described isocyanates is 370 ~ 410, and degree of functionality is 2.85, and in course of reaction, the acid-base value of reactant controls between pH value 7-8.
Further, described isocyanates is mass fraction is the methyl diphenylene diisocyanate of 20% and the triphenylmethane triisocyanate of 80%.
Further, in described raw material, can also add bromo-diphenyl ether material as fire retardant, adding concentration is add described PPG quality 0.01%.
Further, described stabilizing agent is Os-15.
Further, described abrasive material is silicon carbide abrasive.
The manufacture of materials polishing wheel of polyurethane wet type polishing wheel of the present invention, by the mode of wet type polishing, not only significantly improve the precision of tradition grinding, realize dustless or micronic dust polishing, and significantly reduce the cost of precise finiss, be precise finiss can large-scale application in more production fields.
The present invention utilizes polyurethane water absorbing properties good, elasticity is high, high temperature resistant, the characteristic of super abrasive, enriched by macromolecule polyurethane material, uniform micro-pore, add the grinding-material of micron level, New type wet polishing wheel is made by foam process, realize wet type polishing wheel adjustable range large, plasticity is strong, sharp wear-resisting, come off evenly, the product performance that self-sharpening is good, the performance characteristics that machining accuracy is high and automatic equipment rubbing down controllable degree is high, the accurate rubbing down in effective solution 3D face, solve the grinding of non-ferrous metal surface knife mark and self Relict Sand trace line, solve the easy burn blackout phenomenon of size workpiece.The hidden danger security problems that solution dust pollution and dust collection are deposited.In the product line of professional equipment, realize output height yield, high efficiency and high durability energy, reach the ideal effect of high performance-price ratio precise finiss polishing.
In order to understand better and implement, the following detailed description of the present invention.
