Abstract
The invention discloses a bonding agent for a large-size ceramic high-speed sand wheel. The bonding agent is prepared by weighing various components of a bonding agent and putting the components into a bonding agent barrel for mixing 1 hour and sifting the mixture. The bonding agent comprises the following components in percentage by weight: 23-25 percent of clay, 52-55 percent of feldspar powder, and 20-25 percent of high boron glass. The sanding agent provided by the invention has the advantages that the vitrification degree of the bonding agent is improved, the thermal expansion coefficient is reduced, the bonding agent can be matched with grinding material better; as the content of the clay is reduced, the drying shrinkage is further reduced, and the strength of the sand wheel and the rate of the qualified product in manufacturing the sand wheel are improved.
Description
Technical field
The present invention relates to a kind of vitrified bond, relate in particular to a kind of bond that the large size ceramic high speed grinding wheel is used of making.
Background technology
Bond is as a kind of material with the various emery wheels of the bonding one-tenth of abrasive material, and its kind and character will directly affect hardness, the intensity of emery wheel.
At present, traditional vitrified bond fill a prescription at a high speed make below the diameter 600mm, linear velocity 60m/s and following fashion can be competent at, but make more than the diameter 600mm, linear velocity 60-80m/s, particularly during the above emery wheel of thickness 100mm, degradation problem under crackle, the intensity can occur, yield rate is very low.
Summary of the invention
Goal of the invention: goal of the invention of the present invention provides a kind of large size ceramic high speed grinding wheel bond, has improved the vitreous degree of bond, has reduced thermal coefficient of expansion, the product qualified rate when intensity of raising emery wheel and emery wheel are made.
Technical scheme: a kind of large size ceramic high speed grinding wheel bond of the present invention, put into the bond tempering tank and mix to sieve after 1 hour and make by taking by weighing each component of bond, its component and percentage by weight are clay 23-25%, feldspar powder 52-55%, high boron glass 20-25%.
In technique scheme, it is the feldspar below 1300 ℃ in 10-11%, sodium oxide molybdena mass percent in 1.5-2.5%, refractoriness that feldspar powder is selected the potassium oxide mass percent.
Beneficial effect: the present invention compares with existing Ceramic bond agent prescription; its distinguishing feature is to have improved the vitreous degree of bond; reduced thermal coefficient of expansion; can better cooperate with abrasive material; and owing to reduced the content of clay; the dry contraction also lowered to some extent, the product qualified rate the when intensity of raising emery wheel and emery wheel are made.
The specific embodiment
The present invention will be further described below in conjunction with embodiment.
Embodiment one, is the bond of the large size ceramic high speed grinding wheel of 750*100*305 for the manufacture of dimensions:
Be the ratio of clay 23%, feldspar powder 52%, high boron glass 25% by weight percentage, take by weighing above each component and put into the bond mixing tank and mix to sieve after 1 hour and make.
Embodiment two, be the bond of the large size ceramic high speed grinding wheel of 600*75*305 for the manufacture of dimensions:
Be the ratio of clay 25%, feldspar powder 55%, high boron glass 20% by mass percentage, take by weighing above each component and put into the bond mixing tank and mix to sieve after 1 hour and make.
In above-mentioned two embodiment, wherein can to select the potassium oxide mass percent be the feldspar below 1300 ℃ in 10-11%, sodium oxide molybdena mass percent in 1.5-2.5%, refractoriness to feldspar powder.
Owing to improved the vitreous degree of bond; reduced thermal coefficient of expansion; can better cooperate with abrasive material; and owing to reduced the content of clay; the dry contraction also lowered to some extent; make the large size ceramic high speed grinding wheel with bond of the present invention, can improve product qualified rate, produced emery wheel ultimate tensile strength reaches 150-200kg/cm
