▎ 摘　　要

NOVELTY - Solar heat absorbing material comprises 20-30 pts. wt. silicon carbide powder, 15-24 pts. wt. silica sol (30%), 2-5 pts. wt. silane coupling agent KH550, 0.5-2 pts. wt. tetramethylethylenediamine, 1-4 pts. wt. calcium carbonate, 8-12 pts. wt. porous graphene and 0.1-1 pts. wt. polyvinylidene fluoride. USE - The solar heat absorbing material is used for solar thermal power generation system i.e. solar tower type thermal power generating system for replacing fossil energy. ADVANTAGE - The solar heat absorbing material: has low density, small intensity and small porosity; and reduces the environment pollution caused by the release of the organic gas caused by traditional method sintering. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of solar heat absorbing material.
