Abstract
The invention provides a glass lubricating agent, comprising the following raw materials in parts by weight: oily dispersing medium, crystalline flake graphite, hexagonal boron nitride, glycerin monostearate and polyisobutene. The glass lubricating agent disclosed by the invention has good lubricating function and can reduce the friction between a glass product and a mould, and further has the high temperature property which cannot be realized by a common lubricating agent, so that the glass lubricating agent disclosed by the invention can greatly reduce the possibility of sticking the glass product and the mould and can increase the finish degree of the glass product, so that lines are not formed on the surface of the glass product and material blanking is easy to realize.
Description
Technical field
The present invention relates to a kind of glass lubricant.
Background technology
Some glassworks will use the moulding of grinding tool ability in process of production.Glasswork is liquid before moulding, is prone in the production process stick together with grinding tool, and makes the glasswork blanking difficulty that finally obtains, even glasswork is scrapped.
Glass grinding tool in use temperature is higher; Generally in temperature about 700 ℃; Grinding tool and glasswork are not adhered to, use common lubricant not reach requirement, be badly in need of a kind of lubricant that can adapt to hot environment of development.
Summary of the invention
The technical problem that the present invention will solve provides a kind of resistant to elevated temperatures glass lubricant.
For solving the problems of the technologies described above, the invention provides a kind of glass lubricant, comprise the raw material of following each weight part:
86.9 parts ~ 95.4 parts in oiliness dispersion medium
2.5 parts ~ 5.5 parts of crystalline flake graphites
0.1 part ~ 0.3 part of hexagonal boron nitride
0.5 part ~ 1.8 parts of glyceryl monostearates
1.5 parts ~ 5.5 parts of polyisobutene.
In the glass lubricant provided by the invention, adopting the oiliness dispersion medium is the basic raw material of this lubricant, its effect be make other raw materials can homodisperse wherein, and oiliness dispersion medium itself also has certain lubricity.
Crystalline flake graphite: natural crystalloid graphite, its likeness in form fish phosphorus shape belongs to hexagonal system, is laminate structure, has performances such as good high temperature resistant, conduction, heat conduction, lubricated, plastic and acid and alkali-resistance.Crystalline flake graphite is the primary lubricant material of high temp glass lubricant, is characterized in cheap, stable performance.
The crystalline structure of hexagonal boron nitride has the laminate structure similar with graphite, and its chemical property is stable, is a kind of excellent high-temperature solid lubricant.Hexagonal boron nitride, BN, with graphite be isoelectronic species.It has the title of white graphite, has the laminate structure of similar graphite, and good lubricity is arranged, electrical insulating property thermal conductivity and chemical resistance.Chemical property is stable.High temperature resistant 2000 ℃, in nitrogen and argon, using fusing point is 3000 ℃.SP 1 is chemically inert material, under argon gas atmosphere, is still stable until 2700 ℃.
Glyceryl monostearate has good hydrophilicity, is water-in-oil type emulsifier, because the emulsifying property of itself is very strong, also can be used as oil-in-water emulsifiers and uses.The purpose of using glyceryl monostearate in the high temp glass lubricant is in order to increase the stability of lubricant dispersion system.
In order to make being dispersed in the oil medium that lubricant can be uniform and stable, need to use a certain amount of thickening material.Because lubricant temperature in use is higher, must select the thickening material with resistance to elevated temperatures for use.Polyisobutene is the good thickening material of a kind of resistance to elevated temperatures.
In sum, glass lubricant provided by the invention also has the inaccessible characteristic of high temperature resistant this common lubricant under the situation of the effect with the friction between good lubrication function, minimizing glasswork and the mould; Therefore; Adopt glass lubricant provided by the invention, can significantly reduce the possibility of glasswork and mould adhesion, increase the smooth finish of glasswork; Make glass article surface can not produce striped, and blanking is easy.
As optimization of the present invention, said oiliness dispersion medium can be vegetables oil or MO, and MO can be selected No. 32 lubricating oil, No. 46 lubricating oil or No. 68 lubricating oil for use.
