Preparation of the heat accumulating material and the heat collecting plate and the collector of the heat accumulating material having

The present invention provides a method of preparing a heat accumulating material, comprising: Sl, the benzene compound, were dissolved in water, adding catalyst to produce an aqueous solution, the benzene compound, formaldehyde and the molar ratio of the catalyst is from 1: 1.5 to 2.5 : 200 ~ 500; S2, heating the resulting solution until a gel, the gel extraction; S3, the gel solvent replacement to obtain a second gel; S4, after the second gel drying carbonization. Source preparing the rich collector material, the method is simple, and environmental pollution. The present invention is applied to synthetic heat collecting plate and the heat accumulating material in the collector, thereby reducing production costs, and the heat accumulating material can be sprayed directly onto the substrate, and applied to the collector plate, and a further reduction in the collector equipment investment, control production costs.
