Problems solved by technology

[0002] At present, there are many kinds of thermal insulation coatings used in industry at home and abroad, but in the thermal insulation of high-temperature furnaces or other special-shaped, rotating and other thermal equipment, the existing thermal insulation coatings are not very ideal in terms of technical performance and use effect , such as: some have high thermal conductivity, poor high temperature resistance, thick insulation coating, many materials, and high cost; some insulation materials are not strong enough, and they are easy to crack after construction; It can not meet the ideal requirements for adapting to the application of the kiln, thus affecting the thermal efficiency of the equipment

Embodiment 1

[0010] The thermal insulation spray powder is composed of 25% by weight of sepiolite, 9% of brucite, 18% of crocidolite, 12% of basalt, 20% of andalusite, 15% of quartz stone, and 1% of bonding powder. formulated.

Embodiment 2

[0012] The thermal insulation spray powder is prepared by weight percentage: 30% of sepiolite, 10% of brucite, 20% of crocidolite, 13% of basalt, 10% of andalusite, 15% of quartz stone, and 2% of bonding powder made.

Embodiment 3

[0014] The thermal insulation spray powder is prepared by weight percentage: 20% sepiolite, 8.5% brucite, 15% crocidolite, 15% basalt, 20% andalusite, 20% quartz stone, and 1.5% bonding powder made.

[0015] In the thermal insulation spray paint of the present invention, since the spray powder contains functions of anticorrosion, oil resistance, acid resistance and alkali resistance, and strong adsorption and cohesive force, it is not necessary to carry out anticorrosion treatment on the equipment before construction, but to The powdery thermal insulation spraying powder is transported to the construction site, and after adding water and mixing it into a slurry, it can be directly sprayed or smeared on the equipment, which is both thermal insulation and anti-corrosion. In specific use, when it is necessary to prepare spray coatings, the weight ratio of thermal insulation spray powder to water is 1:2.5, and the spray slurry can be obtained after mixing evenly according to the p...

Abstract

The refractory composite heat insulating sprayed paint suitable for high temperature furnace, kiln and other thermal apparatus is powder comprising base material sepiolite, brucite, blue asbestos, basalt, apyre and quartz and high temperature adhering material. In the construction site, the powder is mixed with water to form heat insulting paint. The heat insulting paint has low heat conducting coefficient, high adhering strength, capacity of being used for both cold and hot construction, low comprehensive cost and other advantages.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, in particular to a high-temperature-resistant composite thermal insulation spray coating used for high-temperature kilns or other special-shaped, rotary and other thermal equipment. Background technique [0002] At present, there are many kinds of thermal insulation coatings used in industry at home and abroad, but in the thermal insulation of high-temperature furnaces or other special-shaped, rotating and other thermal equipment, the existing thermal insulation coatings are not very ideal in terms of technical performance and use effect , such as: some have high thermal conductivity, poor high temperature resistance, thick insulation coating, many materials, and high cost; some insulation materials are not strong enough, and they are easy to crack after construction; It can not meet the ideal requirements for adapting to the application of the kiln, thus affecting the therma...
