High-temperature-resistant, infrared radiation preventing and energy-saving coating

Abstract

The invention discloses a high-temperature-resistant and energy-saving coating for preventing infrared emissivity attenuation. The coating is prepared from, by weight, 30-40 parts of high-temperature and high-radiation powder, 10-20 parts of quartz powder, 5-10 parts of super-high-temperature additive, 30-50 parts of bonding agent, 10-20 parts of solvent, 0.1-0.2 part of dispersant, 0.15-0.3 part of coupling agent and 0.05-0.15 part of defoaming agent. The invention aims to form a stable ternary structure inside the coating and hinder internal crystal development and growth when the coating is used at high temperature for a long time. On one hand, the infrared emissivity attenuation of the coating due to crystal growth can be reduced; on the other hand, the phenomena such as coating cracking and piece dropping produced by sintering and shrinkage can be prevented, the service life is prolonged, and the infrared emissivity attenuation is effectively prevented.

Description

technical field [0001] The invention belongs to the field of high-temperature energy-saving coatings, in particular to a high-temperature-resistant anti-infrared radiation rate attenuation energy-saving coating. Background technique [0002] The increasing shortage of mineral resources and energy in the world today seriously threatens the development of world industry. The energy consumption of industrial kilns accounts for about 25% to 40% of the total energy consumption, while the average thermal efficiency of kilns is only about 32%. The main reason is that on the one hand, the heat is lost through the furnace lining and the outer wall of the furnace, and on the other hand, the heat utilization efficiency of the kiln and boiler is low, so that the heat cannot be effectively used and discharged, resulting in a huge waste of energy. High temperature resistant high emissivity coating is a new type of energy-saving material with good heat radiation and heat absorption propert...
