Problems solved by technology

However, due to the thermal conductivity of materials such as glass wool or rock wool
[0003] The disadvantages such as high number, poor tightness inside the material, easy moisture absorption, and poor toughness make the overall thermal insulation efficiency of the flat-panel solar collector low and the service life short

Abstract

The invention discloses a phenolic foam organic thermal-insulation material for a flat-plate solar heat collector. The thermal-insulation material is prepared by mixing, foaming and curing phenolic resin, an organic flame retardant, a foaming agent, a curing agent, a stabilizer and a flexibilizer in parts by weight. The phenolic foam organic thermal-insulation material is applied to the solar heat collector, and can effectively solve the problems such as shrinkage of a water tank when polyurethane foam is used as a thermal-insulation material; the phenolic foam organic thermal-insulation material is fireproof, flame-retardant, wide in working temperature range, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a phenolic foam organic thermal insulation material for flat solar heat collectors. Background technique [0002] Flat-panel solar collectors are generally composed of heat-absorbing plate cores, shells, transparent cover plates, thermal insulation materials and related parts. 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 thermal conductivity of materials such as glass wool or rock wool [0003] The shortcomings such as high number, poor internal tightness of the material, easy moisture absorption, and poor toughness make the overall...
