The utility model relates to a heat preservation composite back plate for a plate solar collector, which belongs to the technical field of solar energy. The heat preservation composite back plate is characterized by at least consisting of one back plate and one heat preservation material by means of adhering. The heat preservation material consists of one benzene plate layer and one heat insulating layer or is formed by jointly freely combining a plurality of benzene plate layers and a plurality of heat insulating layers, and all layers are compounded by means of adhering. The heat insulating layers can be made of rock wool materials, aluminum silicate fiber materials or asbestos materials, a reflecting layer can be further adhered to the upper portion of each heat insulating layer and is made of thin aluminum materials, and the adhesion can be realized by adopting heat resistant rubber materials or polyurethane foaming agent materials. The heat preservation composite back plate has the advantages of simple s
