Abstract

The invention discloses an assembly type heat preservation plate, and aims to solve the problem that the heat preservation performance of an existing heat preservation plate needs to be improved. Theassembly type heat preservation plate comprises a base plate, a supporting layer and a heat preservation layer. The base plate, the supporting layer, and the heat preservation layer are sequentially and fixedly connected into a whole from bottom to top. The preparation process of the supporting layer comprises the following steps: (1) a plurality of rectangular small frames are formed among reinforced steel bars by taking steel bars as keels and constructing a supporting framework on the base plate; (2) a sound absorption felt is filled in the rectangular small frames, and a supporting layer is formed. According to the invention, the ardealite is used as a raw material to prepare the base plate. Meanwhile, the supporting layer and the heat preservation layer are structurally improved, so that the prepared heat preservation plate has excellent performances such as light weight, high strength, water resistance, moisture resistance, stretching resistance and the like. On the basis of thestructural improvement of the heat preservation plate, the heat preservation plate disclosed by the invention is light in weight, high in strength, small in heat conduction coefficient, good in fireproof and waterproof effects and the like. Meanwhile, the ardealite is used as the raw material, so that the resource utilization of the ardealite is realized.
