Insulation material for solar water heater water tank

Abstract

The invention discloses a thermal insulation material for a water tank of a solar water heater. By adopting a method of pouring a material mixing isocyanate, polymer polyol and the like into the thermal insulation material for a water tank of a solar water heater to generate hard polyurethane foam, the preparation process is simple and easy to implement, the production cost is reduced, the complete closure of the whole thermal insulation layer is guaranteed, and the heat loss can be reduced; meanwhile, by adding glass fiber into the material, the problem of size distortion of the polyurethane material is effectively solved; moreover, by adding an age resister and an inorganic flame retardant, the service life of the material is greatly prolonged, and the safety performance of the material is greatly improved.

Description

technical field [0001] The invention relates to the field of polyurethane thermal insulation materials, in particular to a rigid polyurethane foam thermal insulation material for a solar water heater water tank. 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 insulation materials for solar water heater tanks are as follows: [0003] A solar water heater water storage tank made of a new thermal insulation material, the application announcement number is CN132175317A, the w...

AI Technical Summary

Problems solved by technology

[0003] A solar water heater water storage tank made of a new thermal insulation material, the application announcement number is CN132175317A, the water storage tank uses rubber-plastic composite material, ETFE membrane material and glass fiber cloth to make the inner tank insulation layer, the inner tank has a complex structure, and the thermal insulation The layer is composed of multiple layers of different materials, which is inconvenient to install

[0004] A polyurethane hard foam inorganic fire-proof and heat-insulating material for a solar water tank. Working repeatedly in hot and cold environments, the temperature difference is large, and the repeated cold and hot effects cause the material to be prone to aging and failure

[0005] A solar polyurethane thermal insulation material, the application announcement number is CN102229697A, the polyurethane thermal insulation material has good dimensional stability, and the production process is relatively simple, but there is no flame retardant added to the material, because its raw materials are all organic matter, in summer sunlight There is a possibility of fire in case of strong exposure or accident

[0006] To sum up, the existing insulation materials for solar water heater tanks mainly have many disadvantages such as complex insulation layer structure, inconvenient installation, complicated material preparation, high production cost, easy aging and failure of materials, and poor flame retardant effect.
