The invention discloses a thermochromic organic silicon resin and a preparation method and application thereof, wherein polyacid, phenyl siloxane, a silane coupling agent and lower alcohol are mixed and then are heated for reaction, and the reaction materials are subjected to reduced pressure distillation to obtain the thermochromic organic silicon resin, wherein the polyacid is phosphomolybdic acid, phosphotungstic acid, silicomolybdic acid or silicotungstic acid; the silane coupling agent contains an amino group. The invention solves the problems of the inorganic thermochromic material such as unobtrusive color change, poor high-temperature resistance, complicated preparation steps, high price and the like. The thermochromic organic silicon resin prepared by the invention has the advantages of obvious color change, easy preparation and modification, high cost performance, simple preparation process, short process flow, environmental protection, less equipment investment and the like. |
