Solar-energy water tank polyurethane heat insulating material

Abstract

The invention relates to a solar-energy water tank polyurethane heat insulating material. The solar-energy water tank polyurethane heat insulating material is composed of isocyanate, epoxy resin, a foaming agent, polyether polyol, alkali-resistant glass fibers, diatomite, fatty alcohol-polyoxyethylene ether and deionized water. The solar-energy water tank polyurethane heat insulating material has uniformly distributed and fine bubble holes, the heat insulating material is difficult to deform, heat insulating property is stable, heat conductivity coefficient is low, the alkali-resistant glass fibers are added in a white material, the diatomite enables the prepared heating insulating material to be good in flame retardant effect and have fireproof effect, a production method that materials are mixed and poured into a solar-energy water heater water tank heat insulating material layer is adopted, simplicity and easiness are realized, production cost is reduced, integrity and closeness of the whole insulating layer are guaranteed, heat loss can be reduced, and service life of the heat insulating material is prolonged and safety performance of the heat insulating material is also improved.

Description

technical field [0001] The invention relates to the field of polyurethane thermal insulation materials, in particular to a polyurethane thermal insulation material for solar water tanks. Background technique [0002] As the world's energy and environmental problems are becoming more and more severe, countries all over the world are striving to develop clean, environmentally friendly and sustainable renewable energy. As an inexhaustible clean energy, solar energy has been paid more and more attention by people, among which solar water heaters are most widely used. For solar water heaters, the insulation performance of the insulation material of the water tank directly affects the performance of the water heater. At present, the existing thermal insulation materials for solar water heater tanks are mainly organic thermal insulation materials and inorganic thermal insulation materials. Generally, the thermal insulation performance of inorganic thermal insulation materials is w...

AI Technical Summary

Problems solved by technology

At present, the existing thermal insulation materials for solar water heater tanks are mainly organic thermal insulation materials and inorganic thermal insulation materials. Generally, the thermal insulation performance of inorganic thermal insulation materials is worse than that of organic thermal insulation materials. The heat resistance and flame retardancy of organic thermal insulation materials It is lower than inorganic insulation materials. The existing organic insulation materials are mainly polyurethane insulation materials. Special treatment of polyurethane insulation materials, such as adding flame retardants, can solve the problem of low heat resistance and flame retardancy, but The production process is more complicated and the cost is higher
