Abstract
A high-refractivity color glass micro-bead is a TiO2-ZrO2-SiO2 system and is proportionally prepared from TiO2, ZrO2, SiO2, Al2O3, B2O3, ZnO, BaO and coloring agent chosen from NiO, CuO, BaO+ZnO, CuO+MgO, Sb2O3 and CoO.
Description
Technical field
The present invention relates to glass microballon manufacturing technology field, especially make the retroreflecting glass microballon.
Background technology
The existing method of making glass of high refractive index is not as all there being the record of making colour high refractive index glass micro pearl among German Patent DD258133, English Patent GB1130284, U.S. Pat P3293051, USP3419403, Chinese patent CN86106629, the CN99114956.
Existing be applied in the reflective cloth of exposing property on clothes, shoes and hats, the case and bag, reflective leather has only silver gray a kind of, its reason just is that existing high refractive index glass micro pearl is water white, promptly is shown as silver gray after adding reflecting layer (aluminium plating film).Single color has influenced the attractive in appearance of dress ornament, has also limited the use of reflective cloth, reflective leather.If add various coloured films or pigment in bead surface then can reduce its reflective function greatly, increase tooling cost simultaneously again.
Summary of the invention
Purpose of the present invention just is intended to overcome above-mentioned the deficiencies in the prior art, and a kind of colour high refractive index glass micro pearl is provided, and this glass microballon stable performance is difficult for crystallization.The colored microballon of being produced can be processed into versicolor reflective cloth, reflective leather, has gorgeous color daytime in the sun, and night again can be reflective, can satisfy the application of various occasions.
Technical scheme of the present invention is: colour high refractive index glass micro pearl is characterized in that it is by TiO
2-ZrO
2-SiO
2System constitutes, and the weight percent of each raw material is: TiO
222 ~ 50%, ZrO
25 ~ 35%, SiO

35 ~ 10%, B
2O
35 ~ 10%, ZnO 1 ~ 5%, and BaO 0.5 ~ 20%, tinting material 2 ~ 5%, specific refractory power 1.9 ~ 2.2.
The further technical scheme of the present invention is in this component, to contain the CaO 0.5 ~ 5%. of weight percent
The further technical scheme of the present invention is SiO in this component
2With Al
2O
3Content sum weight percent be 15 ~ 45%.Be SiO further
2With Al
2O
3Content sum weight percent be 20 ~ 30%.
The further technical scheme of the present invention is,
Described tinting material is NiO, and the color of glass is a red-violet colour.
Described tinting material is CuO, and the color of glass is light blue.
Described tinting material is CuO+MgO, and the color of glass is green.
Described tinting material is Sb
2O
3, the color of glass is yellow.
Described tinting material is CoO, and the color of glass is a mazarine.
Though be used to make the raw material of glass and can be all cpds (for example carbonate, nitrate) beyond the oxide compound, but in the component melts process, its composition changes over oxide form, and therefore the composition of glass of the present invention is discussed according to the theoretical oxide algorithm.
Known, SiO
2And Al
2O
3Be the main network organizer that constitutes glass, so but because of their refractive index ratio is lower in the composition of glass of the present invention, its two total content should be 15 ~ 45%, better should be 20 ~ 30%.B
2O
3Though and SiO
2, Al
2O
3Equally be the main network organizer that constitutes glass, and have lower specific refractory power equally, but, help the fusion of other components, so in glass of the present invention, be essential because it has lower melt temperature.Simultaneously because B
2O
3Volatile, so in different melting technologies, its content should suitably be adjusted, but main content should be controlled at 5 ~ 10 weight %.ZnO also is a fusing assistant good in the technology for making glass, and is also volatile, and it improves stability, glass in addition, reduces the effect of molten glass viscosity, and we think 1 ~ 5%, and are suitable.CaO can improve glass chemistry stability, but specific refractory power is low, and the 5%th, its upper limit.TiO
2Be a kind of high refractive index oxide, 1840 ℃ of fusing points.Although it has high fusing point separately, be used in when on glass it but can with SiO
2, Al
2O
3Form low-melting eutectic.ZrO
2And TiO
2Effect equally be in order to improve the specific refractory power of glass, ZrO
2+ TiO
2When being lower than 27 weight %, the specific refractory power of glass is too low, does not reach 1.9.Though they are strong nucleators, can cause the glass crystallization, even ZrO
2+ TiO
2Surpass 60%, the also easy quenching of glass of the present invention becomes glass.BaO has fluxing action preferably and can improve the glossiness and the mechanical property of glass, simultaneously BaO refractive index ratio ZrO
2And TiO
2Low but compare SiO
2, Al
2O
3And B
2O
3Want high, help improving the specific refractory power of glass, so in the prior art, it is the main ingredient of making high refractive index glass micro pearl.
The tinting material of using in the glass microballon of the present invention mainly contains following several: NiO can make glass microballon be red-violet colour; CuO can make glass microballon be light blue when having BaO and ZnO to exist in prescription; CuO+MgO can make glass microballon be green; Sb
2O
3, can make glass microballon be yellow; CoO can make glass microballon be mazarine.
The invention has the beneficial effects as follows:
1, glass microballon component of the present invention adopts TiO
2-ZrO
2-SiO
2System constitutes, and has improved the formation ability of glass.
2, use the colored microballon of the present invention, can be processed into versicolor reflective cloth, reflective leather, have gorgeous color daytime in the sun, night again can be reflective, can satisfy the application of various occasions.
3, introduce B
2O
3Reduce the melt temperature of admixtion with ZnO, improved the chemical stability and the anti-crystallization ability of glass.
