Description

Technical Field

[0001] The present application relates to the technical field of aerogel film production equipment, and in particular to an aerogel coating device. Background Art

[0002] Aerogel is the best thermal insulation material in the world. By utilizing the thermal insulation properties of aerogel, a new type of aerogel high-efficiency thermal insulation composite material can be produced, which is applied in the field of energy-saving buildings and has good thermal insulation, fire retardant, sound insulation, light transmission and other properties.

[0003] In the manufacturing process of aerogel thermal insulation sheets, liquid aerogel is usually coated on a polyester film by brushing, and the aerogel is solidified to form an aerogel thermal insulation sheet. However, during the aerogel coating process, since the aerogel is in a liquid state, the liquid aerogel will move to both sides of the coating device during brushing, causing the aerogel to move out of the polyester film and fall into the working environment, thereby polluting the working environment.
