2Colloidal sol;
2) ageing is with aging: the SiO that step 1 is made
2The colloidal sol sealing; Leave standstill the formation gel under the room temperature; With gel ageing at room temperature, use volume ratio to be deionized water: the mixed solution of ethanol=1: 3～1: 10 carries out elementary aging to gel, use volume ratio to be tetraethoxy again: it is aging that the mother liquor of ethanol=1: 3～1: 10 carries out secondary to gel;
3) solvent exchange: the solution little with surface tension carries out solvent exchange to the aging gel that finishes;
4) finishing: adopt hydrophobic agents to mix in 1: 100 by volume～3: 10, gel is soaked in this mixed solution with the little solution of surface tension;
5) surface cleaning: adopt the little solution of surface tension that the gel that finishing finishes is carried out surface cleaning, remove the residual modified outcome of gel surface;
6) drying treatment: the gel that will pass through cleaning places loft drier to carry out constant pressure and dry and obtains block SiO
2Gas gel;
7) grind: SiO
2The airsetting blob of viscose grinds to form particulate state, and adopts filtering net that the macrobead gas gel is filtered out, and obtaining particle diameter is the particle of 100nm～100 μ m;
B) rubber-emulsion paint dilution: by mass ratio is rubber-emulsion paint: water=5: 1～10: 1 mixes stirring;
C) SiO
2Aerogel heat-proof insulation latex coating preparation: take by weighing the SiO that mass percent is 1%-10%
2Aerogel particle adds to and mixes to aerogel particle in the described rubber-emulsion paint diluent of step B and mix fully with rubber-emulsion paint.
7. make the said SiO of claim 6 for one kind
2The method of aerogel heat-proof insulation latex coating, it is characterized in that: the solution that said surface tension is little is one or more in normal hexane, normal heptane, the acetone.
8. make the said SiO of claim 6 for one kind
2The method of aerogel heat-proof insulation latex coating, it is characterized in that: said hydrophobic agents is one or more in trimethylchlorosilane, dimethyldimethoxysil,ne, ethyl dibutyl silane, the trimethylammonium diethoxy silane.
