Abstract

The invention discloses grey glass. The grey glass comprises base glass and a coloring agent, wherein the base glass comprises the following components by weight: 65-70 parts of silicon dioxide, 5-15 parts of calcium oxide, 1-3 parts of magnesium oxide, 2-5 parts of aluminum sesquioxide, 15-20 parts of sodium oxide and 2-7 parts of potassium oxide; and the coloring agent comprises the following components by weight: 1-1.5 parts of iron sesquioxide, 0.2-0.8 part of cobalt oxide, 0.1-0.3 part of selenium and 0.2-0.6 part of nickel. The grey glass has the advantages that the grey glass is favorable for reducing heat in space, reducing ultraviolet radiation, avoiding burn of ultraviolet rays on the skin of a human body and avoiding ageing of decorative materials in the space.

Description

A kind of smoked glass

Technical field

The present invention relates to a kind of smoked glass.

Background technology

Along with the progress of glass industry and the raising of people's living standard, the use of glass in building industry is more and more extensive, and people are more and more higher to the performance requriements of glass, the tinting material that is typically used as smoked glass is, iron, cobalt, selenium, titanium, manganese etc. are selected different colorant combination, generate the smoked glass of different performance, the kind that adds thus chemical element in the tinting material has directly determined the performance of smoked glass.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.

Summary of the invention

The purpose of this invention is to provide a kind of smoked glass.

The technical solution used in the present invention:

A kind of smoked glass comprises parent glass and tinting material, and described this parent glass composition is by weight:

Silicon-dioxide 65-70 part;

Calcium oxide 5-15 part;

Magnesium oxide 1-3 part;

Aluminium sesquioxide 2-5 part;

Sodium oxide 15-20 part;

Potassium oxide 2-7 part;

This coloring agent component is by weight:

Ferric oxide 1-1.5 part;

Cobalt oxide 0.2-0.8 part;

Selenium 0.1-0.3 part;

Nickel 0.2-0.6 part.

The optical signature of described glass is: when thickness is 5.8-6.2mm, and its visible light transmittance rate 65-67%, surface albedo is lower than 6.2%, and the sun power transmitance is lower than 52%.

Advantage of the present invention is: the heat that smoked glass of the present invention is conducive to reduce in the space increases, and reduces ultraviolet radiation, avoids ultraviolet ray burning and avoid the aging of space inner decoration material human body skin.
