The invention relates to the technical field of thermal insulation wallboards, and in particular relates to a mildew-proof and antistatic silicon dioxide aerogel polyurethane composite thermal insulation wallboard and a preparation method thereof. The mildew-proof and antistatic silicon dioxide aerogel polyurethane composite thermal insulation wallboard at least comprises the following raw materials in parts by weight: 1.5 to 5.5 parts of a polyol, 0.7 to 3.1 parts of a quaternary ammonium cationic surfactant, 70 to 100 parts of isocyanate, 60 to 90 parts of polyether polyol, 25 to 50 parts ofsilica aerogel, 5 to 10 parts of carboxybutyl rubber, 0.5 to 0.8 part of a catalyst, 15 to 16 parts of a water foaming agent and 0.1 to 0.2 part of a foam stabilizer. By using the polyol and the quaternary ammonium type cationic surfactant, polyurethane foam has excellent heat preservation performance, high strength, high toughness, waterproofness, mildew resistance and antistatic property. 本发明涉及保温墙板技术领域，更具体地，本发明涉及一种防霉防静
