Embodiment 1

[0013] Example 1: A high-temperature thermal insulation coating for kilns, made of the following raw materials according to the mass ratio: ceramic fiber 5, kyanite powder 5, cobalt oxide 40, manganese oxide 5, binder 5, even Joint agent 1, carbon black 1, mica 1, plant extract 10. Wherein, the coupling agent is vinyltriethylsilane. The plant extracts are: the extracts of aloe vera, Panax notoginseng and Coptis chinensis are mixed according to the ratio of 3:1:2. The binder is polyacrylamide.

[0014] After using the coating prepared in Example 1, the service life of the kiln is increased by 2 times, the energy efficiency is increased by 20%, and no toxic substances are emitted during use.

Embodiment 2

[0015] Example 2: A high-temperature thermal insulation coating for kilns, made of the following raw materials according to the mass ratio: ceramic fiber 30, kyanite powder 20, cobalt oxide 50, manganese oxide 10, binder 10, even Joint agent 5, carbon black 5, mica 5, plant extract 15. Wherein, the coupling agent is vinyltriethylsilane. The plant extracts are: the extracts of aloe vera, Panax notoginseng and Coptis chinensis are mixed according to the ratio of 3:1:2. The binder is cellulose ether.

[0016] After adopting the coating prepared in Example 2, the service life of the kiln is increased by 3 times, the energy efficiency is increased by 25%, and no toxic substances are emitted during use.

Embodiment 3

[0017] Example 3: A high-temperature thermal insulation coating for kilns, made of the following raw materials according to the mass ratio: ceramic fiber 25, kyanite powder 15, cobalt oxide 45, manganese oxide 8, binder 8, even Joint agent 3, carbon black 3, mica 3, plant extract 12. The plant extracts are: the extracts of aloe vera, Panax notoginseng and Coptis chinensis are mixed according to the ratio of 3:1:2. The binder is polyacrylamide.

[0018] After using the coating prepared in Example 3, the service life of the kiln is increased by 5 times, the energy efficiency is increased by 30%, and no toxic substances are emitted during use.

Abstract

The invention provides a high temperature-type thermal insulation coating for a kiln. The high temperature-type thermal insulation coating is prepared from 5-30 parts by mass of ceramic fibers, 5-20 parts by mass of kyanite powder, 40-50 parts by mass of cobalt oxide, 5-10 parts by mass of manganese oxide, 5-10 parts by mass of a binder, 1-5 parts by mass of a coupling agent, 1-5 parts by mass of carbon black, 1-5 parts by mass of mica, and 10-15 parts by mass of plant extract. The coating provided by the invention improves the fire-resistant grade, has good high-temperature bonding strength, effectively prolongs a service life of the kiln after use, greatly increases the work efficiency of the kiln and is environmentally friendly.

Description

technical field [0001] The invention relates to a coating, in particular to a high-temperature thermal insulation coating for kilns. Background technique [0002] With the progress of industries all over the world, the requirements for furnaces are getting higher and higher. Large-scale, high efficiency and long life are an inevitable development trend of furnaces. People began to pay more and more attention to the optimization of kiln structure and materials. At present, the refractory grades of coatings used on kilns are not very high, which seriously affects the life of kiln and energy efficiency during work. Moreover, the existing The paint used in the kiln is harmful to the human body, and brings certain safety hazards to people who work on the side of the kiln for a long time. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to address the deficiencies of the prior art and provide a high-temperature thermal insulat...
