The invention relates to gel felt surface treatment equipment which is characterized in that a spraying mechanism comprises atomizing nozzles arranged on the upper surface and the lower surface of a hydrophobic gel felt, and the atomizing nozzles are used for spraying a hydrophilic modification reagent on the upper surface and the lower surface of the hydrophobic gel felt; the first conveying mechanism comprises a first conveying belt and is used for conveying the hydrophobic gel felt; the frame body is arranged above the first conveying belt; the first film covering mechanism is fixed on the frame body; the second film covering mechanism is arranged on the frame body, and the second film covering mechanism and the first film covering mechanism are arranged at intervals; the annular film is arranged between the first film covering mechanism and the second film covering mechanism in a circulating transmission mode. The first film covering mechanism and the second film covering mechanism are used for pressing and attaching the annular film to the upper surface of the hydrophobic gel felt, and the lower surface of the hydrophobic gel felt is attached to the upper surface of the first conveying belt; the hydrophilic treatment on the surface of the hydrophobic gel felt is homogenized, and the uniform coating and adhesion of the water-based paint are realized.
Description
technical field [0001] The invention belongs to the field of thermal insulation materials, and in particular relates to gel felt surface treatment equipment and a modification method. Background technique [0002] Gel felt is a flexible thermal insulation felt made of nano or metal aerogel as the main material, which is compounded with carbon fiber or ceramic glass fiber wool or pre-oxidized fiber felt through a special process. It is characterized by low thermal conductivity, certain tensile and compressive strength, and belongs to a new type of thermal insulation material. Existing technology for preparing gel felt usually uses silicon source, solvent and catalyst to prepare wet gel to be dried by hydrolysis, gelation, aging and hydrophobization, and then dry the gel to obtain aerogel. [0003] With the extensive demand and application of thermal insulation and energy saving in various fields, the use of gel felt is expanding, and the quality requirements of aerogel felt ...
