Abstract
The invention relates to a ceramic grinding agent, belonging to the field of grinding agents. The ceramic grinding agent provided by the invention is mainly used for grinding silicon nitride ceramic balls. The grinding agent consists of the following components in percentage by mass: 5%-50% of diamond particles, 50%-90% of dispersant, 0.1%-3% of calcium hydrophosphate, 0.5%-2% of sodium tripolyphosphate, 0.5%-2% of sodium dodecyl sulfate and 0.5%-2% of sodium silicate. The grinding agent mainly contains the high-strength diamond particles, the dispersant, a grinding assistant and a dispersing assistant. The grinding agent has the advantages that the grinding efficiency is high and is increased by 30%-50%, the pollution to ceramic bodies is little, the grinding efficiency is increased, and the grinding time is shortened.
Description
Technical field
The present invention relates to a kind of ceramic sanding agent, belong to abrasive field.
Background technology
Ball bearing is the one of rolling bearing, and ball ball is contained in the centre of interior steel ring and outer rim, can bear larger load.Wherein, ceramic ball bearing receives much concern because of its unique feature and wide application field.At present, applying more is silicon nitride ceramic ball bearing.Its advantage is: tripping speed is high, precision stability good, staring torque is little, ceramic ball bearing rigidity is high, dry runnability is good, the life-span is long, is very suitable for keeping high precision, long time running under high speed, high temperature and burn into radiation condition.In addition, the hardness ratio bearing steel of silicon nitride ceramics is high 1 times, and Young's modulus is approximately high by 1/3, and under the condition of same load, the recoverable deformation of silicon nitride ceramics is little, so, use the machine tool chief axis of ceramic ball bearing to there is good running accuracy.
In order to ensure running precision and the work-ing life of ceramic ball bearing, to Ceramic Balls sphericity require highly, simultaneously owing to itself being high-strength material, it is ground more difficult.
Summary of the invention
The object of this invention is to provide a kind of ceramic sanding agent, be mainly the abrasive for polishing silicon nitride Ceramic Balls, this abrasive mainly comprises high-intensity diamond particles, dispersion agent, grinding aid and dispersing auxiliary.It is high that this abrasive has mill efficiency, and ceramic body is polluted less, improves mill efficiency, reduces milling time.
A kind of ceramic sanding agent, described abrasive, by mass percentage, is made up of following component:
Wherein, the granularity of diamond particles is 0.1 ~ 100 μ m, and described diamond particles is spherical, and its degree of sphericity is at least 0.6.
" degree of sphericity " of the present invention refers to the shape degree similar to spheroid of diamond particles.
The preferred described dispersion agent of ceramic sanding agent of the present invention is at least one in ethylene glycol, polyoxyethylene glycol, polypropylene glycol, glycerine, more preferably ethylene glycol.
The degree of sphericity of the preferred described diamond particles of ceramic sanding agent of the present invention is 0.6 ~ 0.9.

Above-mentioned abrasive is preparation as follows preferably:
A preparation method for abrasive, comprises following processing step:
1. raw material weighing: accurate weighing raw material in proportion, and filter;
2. disperse: after tripoly phosphate sodium STPP, sodium laurylsulfonate and water glass are mixed in proportion, be dissolved in dispersion agent;
3. filter: by 2. gained slurries filtration of step, after removal macrobead, add diamond particles;
4. redispersion: by step 3. gained slurry carry out ultrasonic dispersion.
The invention has the beneficial effects as follows: the invention provides a kind of ceramic sanding agent, be mainly the abrasive for polishing silicon nitride Ceramic Balls.This abrasive by mass percentage, is made up of following component: diamond particles: 5% ~ 50%, and dispersion agent: 50% ~ 90%, secondary calcium phosphate: 0.1% ~ 3%, tripoly phosphate sodium STPP: 0.5% ~ 2%, sodium laurylsulfonate: 0.5% ~ 2%, water glass: 0.5% ~ 2%.This abrasive mainly comprises high-intensity diamond particles, dispersion agent, grinding aid and dispersing auxiliary.It is high that this abrasive has mill efficiency, and its mill efficiency has improved 30% ~ 50%, and ceramic body is polluted less, improves mill efficiency, reduces milling time.
Embodiment
Following non-limiting example can make the present invention of those of ordinary skill in the art's comprehend, but does not limit the present invention in any way.
Embodiment 1
Described abrasive, by mass percentage, is made up of following component:
The particle diameter of described diamond particles is that the abrasive of 50 μ m, 5 μ m, 0.5 μ m is roughly ground, fine grinding and super grinding, and dispersion agent is polyoxyethylene glycol.By abrasive and water in mass ratio 1:1 mix after for polishing silicon nitride Ceramic Balls, the sphericity of gained Ceramic Balls is 0.05 μ m, surfaceness is 0.005 μ m.
Claims (2)
