The invention discloses a fireproof efficient solar collector. The solar collector is prepared by mixing a flame retardant, a foaming agent, a curing agent, a stabilizing agent, a toughening agent andchitosan according to a weight ratio and then carrying out foaming and curing. The phenolic foam solar collector of the invention is applied to a solar water heater, can effectively solve the problems of shrinkage of a water tank and the like when polyurethane foam is used as a solar collector; and the added chitosan can further improve heat preservation effect. Phenolic foam is fireproof and fire-retardant, has a wide working temperature range, saves energy and protects environment.
Description
technical field [0001] The invention relates to the technical field of solar energy, in particular to a fireproof and efficient solar heat collector. Background technique [0002] Flat-panel solar collectors are generally composed of a heat-absorbing plate core, a shell, a transparent cover, solar energy and related components. After adding the circulation pipeline and the heat preservation water tank, it can absorb the solar radiation heat and make the water temperature rise. The materials used for the insulation layer of flat-panel solar collectors mainly include rock wool, glass wool, polyurethane, polystyrene, etc., but at present, rock wool and glass wool are mostly used. However, due to the disadvantages of high thermal conductivity, poor internal tightness, easy moisture absorption, and poor toughness of materials such as glass wool or rock wool, the overall thermal insulation efficiency of flat-panel solar collectors is low and the service life is short. Phenolic f...
