Abstract

The present invention relates to a brown coloring agent for color glass and a preparing technique thereof. The granular brown coloring agent for color glass is obtained by the following technical processes of adopting the formula of plumbum and boron, coloring nickel, cadmium and iron, adding zinc and lithium in the formula for coloring, preparing a fluxing agent, preparing glaze melting powder, preparing coloring matters, preparing a coloring agent, etc. The novel coloring agent of the present invention has the advantages of stable product quantity and convenient use, and can greatly reduce the production cost and replace import products. The effect of the novel coloring agent is superior to that of a similar coloring agent. In addition, the brown coloring agent of the present overcomes the defects that color channels and gas bubbles are easily generated by the coloring agent in the same type, and the effects of the brown coloring agent of the present invention are superior to that of the coloring agent in the same type.

Description

Coloured glass brown colouring additive preparation technology

Technical field

The present invention relates to a kind of glass colorant compounds process for production thereof.

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 external product generally adopts chromium painted, 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 brown colouring additive provided by the present invention adopts plumbous boron prescription, and nickel, cadmium, iron are painted, and add zinc, lithium composition in prescription, and its chemical ingredients is as follows: SiO ₂25-30%; Al ₂O ₃3-6%; PbO35-40%; B ₂O ₃5-8%; R ₂O10-20%; Ni ₂O3-7%; CdS2-4%; ZnO10-12%; Se1-3%; Fe ₂O ₃0.5-1%.

Above-mentioned compound can prepare by following method.

(a) preparation of fusing assistant: the fusing assistant proportioning raw materials is SiO ₂30-35%; Al ₂O ₃6-10%;

CaO0.5-2％；MgO0.2-1％；PbO45-50％；B ₂O ₃4-8％；K ₂O+Na ₂O10-15％。

(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 bronzing agent adopts nickel, cadmium, iron, its composition of raw materials: Ni ₂O20-30%; CdS8-12%; Fe ₂O ₃1-2%; ZnO20-30%; Li ₂CO ₃16-20%; Se2-4%; B ₂O ₃6-10%.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 brown particle agent.

Embodiment

The invention will be further described below in conjunction with embodiment

The preparation of the coloured glass brown colouring additive 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%; CaO0.5-2%; MgO0.2-1%; PbO45-50%; 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 50min, 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 brown colouring additive adopts nickel, cadmium, iron, its pigment raw material proportioning: Ni ₂O20-30%; CdS8-12%; Fe ₂O ₃1-2%; ZnO20-30%; Li ₂CO ₃16-20%; Se2-4%; 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

Fusing assistant and pigment by fusion in crucible after 2: 1 mixed, are injected the cold water hardening crack then, broken 4 orders of crossing in dry back, 10 mesh sieves, intermediate particle is the particulate state brown colouring additive, its main chemical compositions: SiO ₂25-30%; Al ₂O ₃3-6%; PbO35-40%; B ₂O ₃5-8%; R ₂O10-20%; Ni ₂O3-7%; CdS2-4%; ZnO10-12%; Se1-3%; Fe ₂O ₃0.5-1%.
