Described emulsion is silicone acrylic emulsion or styrene-acrylic emulsion, and solid content is 45wt%～55wt%, and pH value is 7.0～9.0。
Described Ludox is alkalescence sodium form Ludox, SiO in Ludox2Content be 20wt%～40wt%, particle size distribution is 5～30nm, and pH value is 8.5～10.5。
Described granular polystyrene comes from discarded polystyrene foam particles, and bulk density is 12～20kg/m3, process of sieving, it is preferable that go out the granular polystyrene that particle diameter is 3～5mm。
Described glass bead has I class, II class and III class, it is preferable that II class expanded and vitrified small ball, and its bulk density is 80～120kg/m3, heat conductivity≤0.048W/ (m k)。
Described fibrous material be polypropylene fibre, polyacrylonitrile fibre, vinal, Fypro and wood fibre the mixing of any one or more, insulation clay adds fibrous material, the stress making insulation clay is uniformly dispersed, thus playing the effect of cracking resistance, optimization polypropylene fiber and wood fibre are arranged in pairs or groups, and wherein the length of polypropylene fibre is 2～4mm。
Described talcous molecular formula is Mg3(Si4O10)(OH)2, fineness is 800～1250 orders, it is possible to improve wearability and the caking property of insulation clay；The construction unit of described calcium silicates is silicon-oxy tetrahedron, and for chain structure, heat conductivity is low, is used for being incubated clay and can improve its insulation, heat-proof quality。
Described redispersable latex powder is any one of ethene-vinyl acetate co-polymer class, polyvinyl alcohol, polyethylene kind and polyacrylamide apoplexy due to endogenous wind, it is preferable that ethene-vinyl acetate redispersable latex powder。
The fineness of described hydroxypropyl methyl cellulose is 40～100 orders, and viscosity is 100000～200000mPa s；
Described sodium alginate is a kind of natural polysaccharide, as thickening agent and stabilizer, can add appropriate sodium alginate and can not only improve the viscosity of insulation clay, and can improve clay stability during storing；
Described alcohol ester-12 is alkoxide compound, and chemical name is 2,2,4-trimethyl-1, and 3-pentanediol mono isobutyrate acts primarily as furtherance membrane interaction；
Described air entraining agent is any one in sodium abietate, sodium alkyl benzene sulfonate, OP emulsifying agent, acrylic acid epoxy fat and triterpene saponin, tests gained factually, and the amount of air entrainment in insulation clay has good mechanical property and insulation, heat-proof quality concurrently when 2%～4%；

First carry out the preparation before construction, including to the dedusting decontamination of matrix metope, high convex place pick filling-in etc. flat, pocket；Then the mode of spraying or roller coating is adopted to be coated with construction interface agent；After treating that interfacial agents is completely dried, can construction heat-insulating clay layer, construct twice, the construction thickness of every time is about 8～15mm；After reaching specific thickness, with darby compacting, levelling, to guarantee between insulation clay layer and matrix metope and to be firmly bonded between insulation clay layer inside；The last construction carrying out finish coat on insulation clay layer surface。
The present invention has techniques below feature:
1, with industrial waste flyash and granular polystyrene for raw material, flyash can partly replace cement, had both protected environment, and had turned waste into wealth again, reasonably make use of resource；
2, with silane coupling agent emulsion and Ludox, improve the compactness of film, improve the mechanical property of insulation clay；Composite with organic insulation material and inorganic heat insulation material, make insulation clay have relatively low dry density and heat conductivity, the dry density of clay can be regulated by controlling the addition content of granular polystyrene well；
3, prepared by this patent insulation clay have concurrently excellence mechanical property and thermal and insulating performance, and good with the compatibility of finish coat, adhesion is strong, it is ensured that heat-insulation system have excellence durability；
4, this patent raw material sources are convenient, and production technology is simple, it is often more important that, shorten construction period, saved engineering cost, have a good promotion prospects。
