Abstract
The invention discloses a kind of method of utilizing CNT to improve performances of resin abrasive tools, by adding the CNT of surface in the resin abrasive tools through organising and handling, improve body intensity, impact strength, flex stiffiness and the anti-wear performance of resin abrasive tools, and then the face shape stability and the machining accuracy of raising resin abrasive tools, increase the service life.Used carbon nano tube surface has organo-functional groups such as carboxyl, hydroxyl after handling through organising, and the CNT addition is 1-5wt%.The interpolation CNT is a carboxylic carbon nano-tube, and the grinding tool wearability can improve 10-15%; Adding CNT is the hydroxylating CNT, and the grinding tool wearability can improve 15-20%.
Description
Technical field
The present invention relates to a kind of method of utilizing CNT to improve performances of resin abrasive tools, be particularly related to and improve resin abrasive tools body intensity, impact strength, flex stiffiness and anti-wear performance, and then raising resin abrasive tools face shape stability and machining accuracy, the method that increases the service life.
Background technology
Resin abrasive tools is to be bond with the resin, add materials such as abrasive material, packing material, additive, by batching, mixing, moulding (press forming, casting forming, coated shaping), solidify and process such as back finishing makes, be suitable for a kind of machining tool of different grindings requirements.Advantages such as resin abrasive tools has the grinding efficiency height, and the grinding tool self-sharpening is good, be difficult for stopping up, processed object surface is difficult for burn, polishing performance is good are the grinding tools that is most widely used.But the characteristic of resin, decision resin abrasive tools body intensity, impact strength, flex stiffiness, wearability are not good, cause grinding tool short service life, and face shape poor stability has limited the application of resin abrasive tools.
Adding enhanced fibers such as glass fibre, carbon fiber in resin abrasive tools, improve its body intensity, impact strength, flex stiffiness, wearability, is that resin grinds a much progress of making.
CNT is a kind of One-dimensional Quantum material with special construction (radial dimension is a nanometer scale, and axial dimension is that all seal basically at micron dimension, pipe two ends), and it mainly is made of several layers to tens of layers coaxial pipe the carbon atom that is hexagonal array.Because carbon atom is taked SP2 hydridization in the CNT, compare SP3 hydridization, the S orbital composition is bigger in the SP2 hydridization, make CNT have high-modulus, high strength, CNT tensile strength reaches 50～200GPa, is 100 times of steel, density but has only 1/6 of steel, elastic modelling quantity can reach 1TPa, and is suitable with adamantine elastic modelling quantity, is about 5 times of steel.For the CNT of the solid wall with ideal structure, the about 800GPa of its tensile strength, CNT are the materials with high specific strength that can prepare at present.The hardness and the diamond of CNT are suitable, but have good pliability, can stretch.In industrial enhanced fiber commonly used, a key factor of decision intensity is a draw ratio, i.e. length and diameter ratio at present.The draw ratio that present material engineering Shi Xiwang obtains is 20: 1 at least, and the draw ratio of CNT is desirable high tensile strength fibrous material generally more than 1000: 1.In addition, the CNT good heat-transfer, acid and alkali-resistance, high temperature resistant, have high chemistry and heat endurance, have clear superiority as the resin abrasive tools enhanced fiber.
CNT is as the radial dimension nanometer scale, the One-dimensional Quantum material of axial dimension micron dimension, very easily twine mutually and assemble agglomeratingly, make it be difficult to mix, thereby limited the application of CNT in resin abrasive tools with other material because of factors such as Van der Waals forces.Carbon nano tube surface is repelled or steric effect mutually by like charges after organising and handling, and makes CNT easier being uniformly dispersed in the batch mixing process.
Because CNT has super-strong and super-toughened characteristic and self-lubricating property, and CNT is distributed in the grinding tool with network and winding form, abrasive material difficult drop-off in process of friction and wear is extracted, in addition the organo-functional group of surface organic CNT can with resin generation chemical reaction, thereby improve the adhesion of CNT and resinoid bond.At present, the surface organic CNT is not at home and abroad appeared in the newspapers in the document as the method that enhanced fiber adds resin abrasive tools to.
Summary of the invention
According to present domestic and international research present situation and the raising of considering the resin abrasive tools quality, the present invention seeks to propose a kind of simple, be suitable for, effectively improve resin abrasive tools body intensity, impact strength, flex stiffiness and anti-wear performance, and then the face shape stability and the machining accuracy of raising resin abrasive tools, the method that increases the service life.
The objective of the invention is to be achieved through the following technical solutions, the CNT of the surface being handled through organising by prescription mixes with materials such as abrasive material, packing material, additive, resin-oatmeals, moulding (press forming, casting forming, coated shaping), curings, after resin abrasive tools conventional production process realization such as finishing.
Described CNT for the surface through the processing that organises, have one or more mixing in SWCN, double-walled carbon nano-tube and the multi-walled carbon nano-tubes of functional groups such as carboxyl, hydroxyl.
Described CNT addition is 1-5% (mass ratio).When content is lower, even carbon nanotube is disperseed, carbon nano tube surface organo-functional group and matrix have compatibility preferably, and generation crosslinked winding to a certain degree, forming a kind of network structure, this structure is under external force, can be with the matrix movement and deformation, the energy that can absorption portion be subjected to of nano particle simultaneously, and it is distributed in the network structure, thereby its intensity and toughness are all increased to some extent.But along with the raising of loading, reunion to a certain degree takes place in particle in matrix, not only can not play the effect of enhancing, and its intensity is reduced.
Described resin abrasive tools is to select for use natural or synthetic resin is bond, by batching, mixing, moulding (press forming, casting forming, coated shaping), solidify and process such as back finishing makes, is suitable for a kind of machining tool of different grindings requirements.
The used abrasive material of described resin abrasive tools is one or more mixing in diamond, cubic boron nitride, carborundum, the corundum.
Can identify by grinding experiment the service life of resin abrasive tools, under equal conditions carry out the experiment of grinding glass, the comparison life-span.
