Abstract
The invention discloses a diamond-nano ceramic compound paste for grinding a sealing surface of a valve and relates to the technical field of valve manufacturing. The compound paste is prepared from the following raw materials in percentage by mass: 40-45% of diamond, 25-30 parts of nano ceramic powder, 8-10% of cerium oxide, 3-5% of diatomite, 3-5% of talc powder, 2-3% of Vaseline, 2-3% of tallow oil, 1-2% of gas phase silicon dioxide, 1-2% of titanium dioxide, 0.5-1.5% of cedar seed oil, 0.5-1% of agar, 0.5-1% of urushi tallow, 0.2-0.5% of polyethylene glycol and 5-10% of water. According to the diamond-nano ceramic compound paste disclosed by the invention, the diamond and nano ceramic powder are used as main grinding materials, an appropriate amount of an auxiliary abrasive and a dispersant are added, and the prepared grinding paste is moderate in consistency and can form an oxide film on the sealing surface of the valve, so that the grinding process is accelerated, the grinding effect is improved, and a certain protective effect can be generated to a grinding tool.
Description
Technical field:
The present invention relates to technical field of valve manufacturing, be specifically related to a kind of valve sealing face grinding diamond-nano ceramics compound.
Background technology:
Valve is the function unit in fluid delivery system, has cut-off, adjustment, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.The requirement of valve to its member seal face such as flashboard, flap smooth finish is higher, and in use trim easily corrosion occurs, and easily adheres to the pollutents such as greasy dirt, the stopping property of trim is reduced, and can shorten the work-ing life of valve.
Grinding is a kind of polishing processing method that its trim is conventional in valve manufacture, valve sealing face can be made to obtain very high dimensional precision, geometrical shape and surfaceness, improve the sealing property of trim, thus extend the work-ing life of valve.At present, the grinding of valve sealing face adopts mechanical mill mode more, needs to use lapping liquid or lapping paste to strengthen grinding effect in process of lapping.And although most of lapping liquid and lapping paste can strengthen grinding effect, easily damage grinding machinery in use; In addition because lapping liquid belongs to liquid form, easily cause and use waste, thus increase production cost.
Summary of the invention:
Technical problem to be solved by this invention is to provide that a kind of raw material is easy to get, the simple valve sealing face grinding diamond-nano ceramics compound of preparation method.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A kind of valve sealing face grinding diamond-nano ceramics compound, be made up of the raw material of following massfraction:
Diamond 40-45%, nano-ceramic powder 25-30%, cerium oxide 8-10%, diatomite 3-5%, talcum powder 3-5%, Vaseline 2-3%, butter 2-3%, aerosil 1-2%, titanium dioxide 1-2%, cedar seed oil 0.5-1.5%, agar 0.5-1%, haze tallow 0.5-1%, polyoxyethylene glycol 0.2-0.5%, water 5-10%.
Described valve sealing face grinding diamond-nano ceramics compound is made up of the raw material of following massfraction: diamond 40%, nano-ceramic powder 26%, cerium oxide 8%, diatomite 4%, talcum powder 3%, Vaseline 2.5%, butter 2%, aerosil 1%, titanium dioxide 1%, cedar seed oil 1%, agar 0.5%, haze tallow 0.5%, polyoxyethylene glycol 0.5%, water 10%.
The particle diameter of described nano-ceramic powder is 80-100 nanometer.
A preparation method for valve sealing face grinding diamond-nano ceramics compound, comprises the following steps:
(1) first in high-speed mixer, Vaseline, butter and haze tallow is added, be warming up to 50-55 DEG C make it all melt after add agar and water again, continue to be warming up to 90-100 DEG C, diamond, nano-ceramic powder and cerium oxide is added after agar all melts, mixing 15-20min, naturally cooling cooling subsequently, adds diatomite and aerosil when temperature is down to 40-45 DEG C, continue mixing 10-15min, obtain mixture I;
(2) first joined in sand mill by mixture I, then add talcum powder, titanium dioxide, cedar seed oil and polyoxyethylene glycol, sand milling to fineness obtains mixtures II after being less than 10um;
(3) join in freeze drier by mixtures II, being refrigerated to water content is about 5%, and last discharging, barrelling obtain target lapping paste.
The invention has the beneficial effects as follows: the present invention is main abrasive material with diamond and nano-ceramic powder; and add appropriate auxiliary abrasive and dispersion agent; obtained lapping paste denseness is moderate; oxide film can be formed at valve sealing face; thus acceleration process of lapping; improve grinding effect, and certain provide protection can be produced to lap tool.
