Light thermal insulation coating

Abstract

The invention relates to a light thermal insulation coating, which is characterized by consisting of refractory cellucotton, aluminate cement, flint clay powder, micro-porous light mullite powder, clay and solid water glass powder, wherein the materials are stirred by adding water and then subjected to coating construction. The light thermal insulation coating is characterized by comprising the following coating raw materials in percentage by weight: 15-30 percent of refractory cellucotton, 15-20 percent of micro-porous light mullite powder, 20-30 percent of aluminate cement, 10-20 percent of flint clay powder, 3-10 percent of clay and 3-6 pecent of solid water glass. The proportioned mixture is uniformly stirred, 20-45 percent of water is added, the mixture is stirred to a proper state to perform coating construction, and the materials are adhered to a construction body. The light thermal insulation coating has the advantages of good thermal insulation effect, high extreme cold and heat resistance, easiness in improvement on strength and coating, friendliness to operation environment, manual direct coating, high adhesion and capability of being constructed on a wall surface and a steel plate without an anchor member at any angle.

Description

technical field [0001] The invention belongs to the field of refractory materials, and in particular relates to a light-weight thermal insulation spread material. Background technique [0002] With the rapid development of the world economy, energy is becoming increasingly tense. Energy is the foundation of our human existence. In today's energy shortage, it is important to find new energy or explore alternative energy, but improving energy utilization is also an important means to change the current energy shortage. Especially in high-energy-consuming industries, such as high-temperature kilns, energy saving is the first to bear the brunt. In terms of various energy-saving measures, thermal insulation technology is widely used due to its huge energy saving, low investment and easy implementation.

Problems solved by technology

[0003] According to literature search, in the selection of lightweight insulation materials, traditional lightweight insulation bricks have good insulation effect, but at the same time, there are defects of low strength and low service temperature. The use of alumina hollow ball bricks is high in temperature, but the cost is high, and there are gaps in the bricks, the integrity is not strong, and the disadvantages of large heat loss; lightweight castables have the disadvantages of large water addition, large linear shrinkage, and easy cracking; silicic acid The use temperature of aluminum fiber blanket is 1100℃, but the construction is inconvenient
