Abstract

The present invention relates to a color glass coloring agent and a preparation technique thereof. The color glass coloring agent is prepared from plumbum, boron, zinc, chromium, lithium and copper; the preparation technique comprises technical processes of fluxing agent preparation, glaze fusing powder preparation, coloring matter preparation, coloring agent preparation and the like, so that a granular color glass green coloring agent is obtained. When the novel coloring agent is used, the quality of a product is stable; the novel coloring agent overcomes the defect of the easy generation of color channels and gas bubbles of the similar products and has the advantage of convenient operation; the effect of the novel coloring agent is superior to that of the similar coloring agent; the production cost of the novel coloring agent is greatly reduced; and the novel coloring agent can replace import products.

Description

Coloured glass green colourant and preparation technology

Technical field

The present invention relates to a kind of glass coloring immunomodulator compounds and preparation method.

Background technology

Late 1960s, coloured glass begins to occur abroad, China began one's study the seventies, originally be in the road, to add Powdered pigment, dye melts is after stirring action, make itself and parent glass be mixed into the material of homogeneous, through the homogenizing postforming, yet this coloured glass is had to limited popularization.The first, when in glass metal, adding tinting material, can produce many difficulties, the second, glass metal is carried out second-heating detrimentally affect, and subject matter is reboil bubble to occur.U.S.'s import particulate state tinting material is used in the back, and this tinting material generally adopts the boracic prescription, though improvement is arranged, but still have unstable product quality, defectives such as look road, bubble, color lump very easily appear, and the product import, cost an arm and a leg, be badly in need of substitute products.

Summary of the invention

Cost an arm and a leg in order to overcome prior art, unstable product quality, effect is undesirable, defectives such as look road, bubble, color lump very easily occur, the invention provides a kind of new coloured glass tinting material and production technique.

New coloured glass green colourant provided by the present invention adopts plumbous boron prescription, and adds zinc, lithium composition in prescription, adopts chromium, copper coloring, and its chemical ingredients is as follows: SiO ₂20-25%; Al ₂O ₃3-5%; PbO 30-35%; B ₂O ₃4-8%; CuO 2-3%; Cr ₂O ₃5-8%; R ₂O 15-20%; ZnO 6-8%.

Above-mentioned compound can prepare by following method.

(a) preparation of fusing assistant: the fusing assistant proportioning raw materials is: SiO ₂30-35%; AI ₂O ₃6-10%; CaO 0.5-2%; MgO 0.1-1%; PbO 45-50%; B ₂O ₃4-8%; K ₂O+Na ₂O 10-15%.

(b) preparation of melted glaze powder: fusing assistant is heated in crucible 1100-1200 ℃ by above-mentioned chemical constitution batching back and is founded, soak 40-60min, and through shrend, ball milling, drying, sieving obtains melted glaze powder.

(c) preparation of pigment, it is toner that copper, chromium are adopted in green agent, its composition of raw materials: Cr ₂O ₃20-30%; CuO 8-12%; ZnO 16-20%; Li ₂CO ₃16-20%; B ₂O ₃12-20%.Borax is earlier soluble in water, and powder adds behind all the other raw material blendings, mixes oven dry thoroughly, and ball milling sieves, and obtains pigment

(d) preparation of tinting material: fusing assistant and pigment by fusion in crucible after 2: 1 mixed, are injected the cold water hardening crack then, and dry back fragmentation is sieved, the green particles agent.

Embodiment

The invention will be further described below in conjunction with embodiment

The preparation of the coloured glass green colourant of indication of the present invention realizes by following processing method.

One, the preparation of fusing assistant

In order to adapt to the processing temperature of expecting the road and the chemical constitution and the chemical property of glass basestocks.Reduce PbO, B ₂O ₃Deng the volatile quantity of raw material, fusing assistant is selected following raw materials according proportioning: SiO for use ₂30-35%; Al ₂O ₃6-10%; CaO 0.5-2%; MgO 0.1-1%; PbO 45-50%; B ₂O ₃4-8%; K ₂O+Na ₂O10-15%.

Two, the preparation of melted glaze powder

Fusing assistant is formed the batching back by its said ratio and found into vitreum in crucible, and glass melting temperature is about 1180 ℃, and top temperature keeps 45min, pours into then and carries out shrend in the water, the molten glaze ball milling after the shrend 28 hours.80 mesh sieves are crossed in dry back, obtain powdered frit.

Three, the preparation of pigment

It is toner that green colourant adopts copper, chromium, its pigment raw material proportioning: Cr ₂O ₃20-30%; CuO 8-12%; ZnO 16-20%; Li ₂CO ₃16-20%; B ₂O ₃6-10%.The raw materials used chemical pure raw material that all adopts of pigment requires steady quality, and borax is earlier soluble in water, and powder behind all the other raw material blendings is added, mixes thoroughly oven dry, and ball milling was crossed 280 mesh sieves about 25 hours, obtained pigment.

Four, the preparation of tinting material

By after 2: 1 mixed, the cold water hardening crack is injected in fusion in crucible then with fusing assistant and pigment, broken 4 orders of crossing in dry back, and 10 mesh sieves, intermediate particle is the particulate state green colourant, its main chemical compositions: SiO ₂20-25%; Al ₂O ₃3-5%; PbO 30-35%; B ₂O ₃4-8%; CuO 2-3%; Cr ₂O ₃5-8%; R ₂O 15-20%; ZnO 6-8%.

Claims
