Abstract
The invention relates to the technical field of insulating materials, specifically to a high-strength lightweight insulating castable. The high-strength lightweight insulating castable comprises, by weight, 30 to 50% of lightweight aggregate, 10 to 20% of expanded perlite, 5 to 10% of cement, 5 to 10% of silica micropowder, 1 to 3% of solid soluble glass and 0.5 to 1% of alumina silicate fiber. The objective of the invention is to provide the high-strength lightweight insulating castable with ideal performance and energy-saving and emission-reducing effect.
Description
Technical field
The present invention relates to the technical field of insulation material, specifically a kind of high-strength light heat-preserving castable.
Background technology
Flourish along with national economy, low energy consumption, low stain, low emission etc. require to improve constantly. At present the usability of fireclay insulating refractory is proposed increasingly higher requirement, it is desirable to thermal conductivity and the Linear change rate of lightening casting material are lower, and after burning, volume contraction is little, and compressive resistance and operating temperature are higher.
Summary of the invention
It is an object of the invention to provide the high-strength light heat-preserving castable of a kind of performance ideal, energy-saving and emission-reduction.
The technical solution used in the present invention is, a kind of high-strength light heat-preserving castable, forms by following percentage by weight: aglite 30-50%, expanded perlite 10-20%, cement 5-10%, silicon dioxide ultrafine powder 5-10%, solid water glass 1-3%, alumina silicate fibre 0.5-1%.
Saying further, described aglite is golf type mullite hollow spheres or light weight alumina hollow ball.
The method have the advantages that have excellent thermal insulation heat insulation effect, reduce the thermal losses of high temperature kiln and various industrial high temperature equipment, compressive resistance and operating temperature are higher, and after burning, volume contraction is little, and thermal conductivity coefficient is low.
