In the present embodiment, the step(1)Including hydrophobically modified step;The hydrophobically modified step is to carry out hydrophobically modified to aeroge in closed hydrophobic modifier gaseous environment;The hydrophobic modifier be trim,ethylchlorosilane, HMDS, HMDO, MTMS, MTES, dimethyldimethoxysil,ne, dimethyldiethoxysilane, γ-aminopropyltrimethoxysilane, gamma-aminopropyl-triethoxy-silane, γ-(The oxygen of 2,3- epoxies third)Propyl trimethoxy silicane, γ-methacryloxypropyl trimethoxy silane, N-(β-aminoethyl)One or more in-gamma-aminopropyl-triethoxy-silane.
So, because in existing aerogel material preparation method, precursor, displacement solvent and drying process have significant effect to the hydrophobicity of aeroge, if the surface of aeroge and the contact angle of water are more than 90 °, hydrophobically modified can not be carried out in advance, directly carry out surface hydrophilic modification;If the surface of aeroge and the contact angle of water are less than 90 °, need to carry out hydrophobically modified in advance;Hydrophobically modified is carried out to aeroge in closed hydrophobic modifier gaseous environment, modified effect except significantly improving aeroge, ensure that inside nano-porous structure is not destroyed outer during follow-up hydrophilic modifying, also significantly improves modification efficiency and production efficiency, reduces production cost.
In the present embodiment, the step(1)Also include surface hydrophilic modification step;The surface hydrophilic modification is that aeroge surface is modified using surface hydrophilic modification solution;The surface hydrophilic modification solution is surfactant and the aqueous solution or the aqueous solution of low surface tension solvent of low surface tension solvent;The surfactant is the one or more in anionic surfactant, cationic surface active agent, amphoteric surfactant, nonionic surface active agent;The anionic surfactant is the one or more in fatty alcohol phosphates, aliphatic alcohol polyoxyvinethene phosphate salt, alkyl sulfate, fatty alcohol polyoxyethylene ether sulfate, fatty acid glyceride sulfate, sulphation ricinoleate, cycloalkanes sulfate, fatty acid amide alkyl sulfate, alkylbenzenesulfonate, alkylsulfonate, fatty acid methyl ester ethoxylate sulfonate, MES, aliphatic alcohol polyethenoxy ether carboxylate;The cationic surface active agent is aliphatic ammonium salt;The amphoteric surfactant is the one or more in alkyl amino acid, carboxylic acid group's glycine betaine, sulfobetaines, phosphate glycine betaine, alkyl hydroxy amine oxide;The nonionic surface active agent is the one or more in aliphatic polyester, APES, high-carbon fatty alcohol polyoxyethylene ether, polyoxyethylene carboxylate, fatty acid methyl ester ethoxylate, the oxireme addition product of polypropylene glycol, sorbitan ester, sucrose fatty ester, alkyl esteramides;The low surface tension solvent is the one or more in acetone, n-hexane, pentane, normal heptane, ethanol, isopropanol, the tert-butyl alcohol, propane diols, glycerine;In the surface hydrophilic modification step, in addition to additional physical field action step;The additional physical field action step is the one or more in far infrared radiation, stirring, ultrasonication, ball milling.
So, using the aqueous solution of the aqueous solution or low surface tension solvent of surfactant and low surface tension solvent, in hydrophilic modifying processing procedure is carried out to hydrophobic aerogel surface there is surface to cooperate with hydrophilic modifying effect, it is remarkably improved wetting spreading rate of the surface hydrophilic modification solution on aeroge surface, significantly slow simultaneously to the wetting extension inside aeroge, by regulating and controlling the consumption of modified solution, the regulation and control to aeroge surface hydrophilic thickness degree can be accurately realized;Low surface tension solvent not only with water and surfactant there is surface to cooperate with hydrophilic modifying effect, and the capillary force into the hydrophilic modifying solution in the nano-pore of aeroge top layer can be greatly reduced, it is easy to that the hydrophilic modifying solution in the nano-pore of aeroge top layer is evaporated by drying process, without destroying its nano-porous structure, good interface cohesion is formed with fireproof gum compound tense so as to realize;Additional physics field action can significantly improve the activity and the contact probability with aeroge of surface hydrophilic modification solution, reduce dosage of surfactant, improve the surface hydrophilic modification speed of aeroge, reduce cost, improve production efficiency.
In the present embodiment, the step(1)Also include drying process step;The drying process step is one kind in far-infrared ray drying, spray drying, microwave drying, constant pressure and dry, supercritical drying, subcritical drying, freeze-drying.
If in this way, aerogel powder and water-base resin compound tense after hydrophilic modifying, the remaining hydrophilic modifying solution in top layer can influence interface cohesion, processing need to be pre-dried;Using above-mentioned drying process, on the premise of ensuring that aeroge top layer nano-pore structure is not destroyed, surface hydrophilic modification solution remaining in the nano-pore of aeroge top layer is evaporated, the interface bond strength between aeroge and aqueous transparent fireproof gum is improved.
In the present embodiment, the step(1)Afterwards and step(2)Before can also be to step(1)Aeroge carry out Surface coating processing;The Surface coating processing is, by dip-coating method or low temperature plasma polymerization method, one or more layers described aqueous transparent adhesive to be coated on into step(1)Aeroge surface;Also include curing process after the Surface coating processing;The curing process is one kind in far infrared radiation, microwave heating, spray drying, ultraviolet radiation.
In this way, the present invention utilizes anti-reflection film principle, in one or more layers aqueous transparent adhesive film of aeroge Surface coating, the refractive index of clad improves the visible light transmissivity of the fireproof gum of aerogel-congtg between aeroge and aqueous transparent adhesive system;It is to insert the aeroge with inner hydrophobic, surface hydrophilic architectural feature in the container being made up of screen pack to lift infusion process, immerse in aqueous transparent adhesive, after aeroge is fully contacted with aqueous transparent adhesive, take out, solidification, repeat the above steps the aeroge for being made and coating one or more layers aqueous transparent adhesive film;Low temperature plasma polymerization method is that the excitation of aqueous transparent adhesive material is activated into free radical isoreactivity particle, form gaseous phase free radical, gaseous phase free radical absorption forms surface free radical on the aeroge surface with inner hydrophobic, surface hydrophilic architectural feature, with monomer derived from gas phase original monomer or plasma on aeroge surface polymerisation occurs for surface free radical, film is generated, repeat the above steps the aeroge for being made and coating one or more layers aqueous transparent adhesive film.
In the present embodiment, the step(2)In can also add the one or more in the fire retardant, the decentralized medium, the auxiliary agent;The step(2)Can mix the aerogel particle or the aerogel powder with the aqueous transparent adhesive and the fire retardant, the decentralized medium, the auxiliary agent;The step(2)It can also be and mix aqueous transparent adhesive with the fire retardant, the decentralized medium, the auxiliary agent, be then coated on the aeroge plate surface.
