Abstract
The present invention relates to a kind of method for improving Low-temperature vitrified bond heat sensitivity.Belong to grinding materials and grinding tool and vitrified bond technical field.Its technical scheme is：Fine-grained alpha-alumina powder mix simultaneously high melt with common Low-temperature vitrified bond raw material, at this moment alpha alumina particles interface is fully reacted with liquid ceramics bonding agent while remains able to ensure its intensity and hardness, therefore the Low-temperature vitrified bond made using such a method remains in very big temperature range the state that liquid phase coexists with solid phase in sintering process, therefore can greatly improve the temperature sensitivity of Low-temperature vitrified bond.The advantages of the method is：The mobility of bonding agent in sintering process is being adjusted in the case of not changing vitrified bond refractoriness substantially only by the dosage can for changing alpha-aluminium oxide so that bonding agent substantially reduces to the sensitiveness of temperature, so as to improve product stability.
Description
Technical field
Patent of the present invention belongs to grinding materials and grinding tool and vitrified bond technical field, and in particular to one kind improves low-temp ceramics knot
The method of mixture heat sensitivity.
Background technology
Ceramic abrasive tool, which compares other grinding tools, to be had the advantages that good grinding accuracy height, self-sharpening, acid and alkali-resistance, easily repairs, so
It is widely used in corase grind, fine grinding and polishing, ceramic abrasive tool occupies critically important status especially in Precision Machining.Making pottery
The grinding performance of grinding tool and abrasive particle, bonding agent and stomata are closely related in porcelain mill tool, and the performance of vitrified bond is to influence mill
Has one of most important reason of performance.In ultrahard material ceramic abrasive tool, requirement of the super-hard abrasive to bonding agent is of a relatively high,
One of them critically important performance is that the refractoriness of requirement bonding agent is low, generally below 800 DEG C, and referred to as low-temp ceramics combine
Agent, abrasive particle fire damage is easily caused if refractoriness is too high.With the development of process technology, industrial production is to low-temp ceramics knot
The requirement more and more higher of mixture, for example, grinding tool quality stability, common Low-temperature vitrified bond is in sintering process to temperature
Very sensitive, if furnace temperature slightly difference, it is very big to result in vitrified bond mobility difference, so that grinding tool quality fluctuation
It is larger.
Therefore, the present invention is too quick to temperature in sintering process for the Low-temperature vitrified bond used in industrial production
The shortcomings that sense, propose a kind of method for improving Low-temperature vitrified bond heat sensitivity.
The content of the invention
Technical problem：The technical problem to be solved in the invention is sensitiveness of the Low-temperature vitrified bond to sintering temperature
Height, cause ceramic abrasive tool quality unstable.
Technical scheme：To achieve these goals, the present invention provides a kind of improvement Low-temperature vitrified bond heat sensitivity
Method comprises the following steps：
1. select a kind of Low-temperature vitrified bond composition of raw materials；
2. select ultra-fine alpha-alumina powder；
3. by step 1. the vitrified bond raw material of middle selection and step 2. middle selection alpha-alumina powder in proportion uniformly altogether
It is mixed；
4. by step 3. in blend dry after in smelting furnace high temperature melting, and quickly cooling obtain frit；
5. by step 4. in frit levigate turn into vitrified bond.
The step 1. middle Low-temperature vitrified bond refractoriness≤700 DEG C.
The step 2. in ultra-fine alpha-alumina powder particle mean size in 200nm ~ 5 μm.
The adding proportion of the step 3. middle alpha-alumina powder accounts for the 10% ~ 50% of vitrified bond material quality, batch mixing side
Formula is dry-mixed or wet ball-milling.
The step 4. in smelting temperature should be between 1200 DEG C ~ 1600 DEG C.
The levigate method of the step 5. middle frit includes：Ball mill grinding or air-flow crushing.
The beneficial effect comprise that：Vitrified bond prepared by the present invention is in sintering process in very big temperature model
The state that liquid phase coexists with solid phase is remained in enclosing, therefore can greatly improve the temperature sensitivity of Low-temperature vitrified bond.
With reference to agent instantiation, the present invention is further described, but protection scope of the present invention not limited to this.
