Abstract
The present invention relates to a kind of manufacture method of potassium titanate crystal whisker, its manufacture method are specific as follows：First, raw materials for production potassium carbonate and metatitanic acid are pressed 1：1 mixing, add the water that content is 75%；Secondly, 0.01%~0.02% sulphur, 0.01%~0.02% phosphorus are added in mixing suspension；Then, 3%~8% cosolvent is added in mixing suspension；Finally, mixing suspension is separated out into crystal using being heated at high temperature.It the advantage is that：The raw materials for production use potassium carbonate and metatitanic acid, and in proportion 1:1 mixing, can be made into crystal whisker of hexa potassium titanate, frictional behaviour is excellent；Whisker synthesis uses flux method, and cosolvent uses potassium manganate, can make whisker high income, and pattern is good；Mixing suspension by temperature control between 1000 DEG C~1200 DEG C, can both prevent that thermal conductivity coefficient is too high, can prevent whisker aging again using high-temperature heating.
Description
Technical field
The present invention relates to a kind of manufacture method of friction material potassium titanate crystal whisker, belong to field of material technology.
Background technology
The research of whisker has the history of nearly 40 years, and in the mid-80, the higher potassium titanate crystal whisker of cost performance is in Japan
Come out, whisker just starts largely to be used.
Up to the present, people have synthesized nearly hundred kinds of whisker, but put into the only carborundum of industrialized production, nitridation
A small amount of kind such as silicon, aluminum oxide, potassium titanate, calcium carbide, calcium sulfate, zinc oxide；And what friction material was commonly used with potassium titanate crystal whisker
Raw materials for production are potassium carbonate and titanium dioxide, and frictional behaviour is poor；Conventional potassium titanate crystal whisker synthetic method uses sintering process, system
It is poor into whisker quality, pattern, it is unable to reach the requirement needed for high quality whisker.
The content of the invention
Present invention solves the technical problem that it is to provide a kind of new raw materials for production proportioning, the whisker that quality is high, pattern is good
Manufacture method.
In order to solve the above technical problems, the technical scheme is that：A kind of manufacture of friction material potassium titanate crystal whisker
Method, its innovative point are：Its manufacture method is specific as follows：
(1) raw materials for production choose potassium carbonate and metatitanic acid, and by 1：1 ratio mixing, is made suspension, wherein water content
For 75%；
(2) 0.01%~0.02% sulphur, 0.01%~0.02% phosphorus are added in suspension；
(3) 3%~8% cosolvent is added in suspension, forms mixing suspension；
(4) mixing suspension is separated out into crystal using being heated at high temperature.
Further, the cosolvent uses potassium manganate.
Further, the mixed solution heating and temperature control is between 1000 DEG C~1200 DEG C.
The advantage of the invention is that：
(1) raw materials for production use potassium carbonate and metatitanic acid, and in proportion 1:1 mixing, can be made into crystal whisker of hexa potassium titanate,
Frictional behaviour is excellent；
(2) whisker synthesis uses flux method, and cosolvent uses potassium manganate, can make whisker high income, and pattern is good；
(3) mixing suspension is using high-temperature heating, and temperature control can both be prevented into heat between 1000 DEG C~1200 DEG C
It is too high to lead coefficient, whisker aging can be prevented again.
Embodiment
The invention discloses a kind of manufacture method of potassium titanate crystal whisker, the manufacture method step is specific as follows：
(1) raw materials for production choose potassium carbonate and metatitanic acid, and by 1：1 ratio mixing, is made suspension, wherein water content
For 75%；
(2) 0.01%~0.02% sulphur, 0.01%~0.02% phosphorus are added in suspension；
(3) 3%~8% cosolvent is added in suspension, forms mixing suspension；
(4) mixing suspension is separated out into crystal using being heated at high temperature.
Following table is the relation table that heating-up temperature influences on separating out crystal：
| 950 | 1000 | 1100 | 1200 | 1250 | 1300 | |
| Thermal conductivity coefficient | 0.022 | 0.019 | 0.016 | 0.013 | 0.011 | 0.009 |
| Degree of aging | Without aging | Without aging | Without aging | Without aging | Aging | Aging |
With the rise of temperature, thermal conductivity coefficient reduces, and the thermal conductivity coefficient general control of whisker is between 0.01~0.02,
Need to prevent whisker aging in heating process simultaneously；As seen from the above table, heating-up temperature must be controlled between 1000 DEG C~1200 DEG C.
The general principle and principal character of the present invention has been shown and described above.It should be understood by those skilled in the art that
The present invention is not limited to the above embodiments, merely illustrating the principles of the invention described in above-described embodiment and specification,
Without departing from the spirit and scope, various changes and modifications of the present invention are possible, and these changes and improvements all fall
Enter in scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
