Acid salt solution maintains 40 DEG C of temperature, at the uniform velocity stirs 30min with the rate of 150r/min, obtain viscous sol, then colloidal sol is equal
It is even to be coated in nonwoven surface, 12h is finally stood at room temperature, and sol layer is changed into gel layer, obtains the nothing with gel layer
Woven fabric；
(3) non-woven fabrics with gel layer for first obtaining step (2) immerses in dehydrated alcohol, is stood under constant temperature conditions
Aging process then takes out and is placed in isopropanol solvent, impregnates 6 ~ 7h, finally takes out dry viscous to get being handled with softening
Glue fiber is the soft comfortable aeroge cloth material of reinforcing fiber.
Silica solution is dispersion liquid of the nanoscale silica dioxide granule in water or in solvent, and the dioxy in silica solution
SiClx contains a large amount of water and hydroxyl, and the characteristic with a certain amount of film forming dissolution, water resistance, heat resistance can be excellent, can form cause
Close and compared with hard coat film, therefore, the present invention selects silica solution to prepare aeroge sol solutions as raw material.As a preference of the present invention,
In step (1) described silica solution, 20 ~ 25wt% of dioxide-containing silica, 0.2 ~ 0.4wt% of sodium oxide content, the quality of the methanol
For silica solution gross mass 28 ~ 32%.
Amphoteric surfactant is a kind of surface modifier of mildness, amphoteric surfactant molecule and single yin from
Subtype, cationic are different, have existed simultaneously acidic groups and basic group in one end of molecule, acidic groups is mostly carboxyl, sulfonic acid
Base or phosphate, basic group are then amido or quaternary ammonium group, can with anion, nonionic surface active agent mixture, can it is acidproof,
Alkali, salt and alkali salt, amphoteric surfactant usually have good washing, dispersion, emulsification, sterilization, flexible fibre
With the performances such as antistatic；No matter especially betaine type amphoteric surfac-tant, maximum feature are in acid, neutral or alkalinity
Aqueous solution in can dissolve, and penetration, detergency and the performances such as antistatic are also preferable, are preferable emulsifier, softness
Agent.Therefore, the present invention selects betaine type amphoteric surfac-tant as surface modifier.As a preference of the present invention, step
