Abstract
The invention discloses a solar heat absorption material. The solar heat absorption material comprises resin, a curing agent, an absorbent, a solvent, an assistant and an absorption reinforcing agent. 2-Bromo-2-(2-fluorophenyl)-1-clopropylethanone added to a coating, the resin and the absorbent form an optical trap capture agent, so the solar absorption rate of the material can reach 96-96.5%, and the emissivity is 0.2-0.25.
Description
Technical field
The invention belongs to heat-absorbing paint, belong to the solar energy heat absorbing material for flat plate collector especially.
Background technology
Along with the domestic energy, environmental issue, sun power more and more comes into one's own as the inexhaustible clean energy of one.Solar energy heat absorbing coating is coating light energy conversion being become heat energy, and by the surface of its direct brushing base material, help base material absorb solar heat, existing coating generally includes following component: resin, solidifying agent, absorption agent, solvent, auxiliary agent.Different auxiliary agents is selected, and the optical property of coating can be made to have very large difference.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of solar energy heat absorbing material of good in optical property.
The technical scheme of this technical solution problem is: solar energy heat absorbing material, comprises the material of following weight part:
