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 thermal insulation materials. The existing organic thermal insulation materials are mainly polyurethane thermal insulation materials. The flame retardant effect of the material is good, and it has the function of fire prevention, but the flexibility of the insulation material is poor, the water absorption rate is high, and the use effect is not ideal

Abstract

The invention relates to an organic polyurethane fireproof and heat insulating material for a solar water tank. The material is mainly prepared from a component A and a component B through mixing, wherein the component A comprises isocyanate, polyvinyl alcohol and a foaming agent; the component B comprises polyether glycol, gelatin powder, activated aluminum oxide, calcium carbide, tributyl phosphate and deionized water. According to the organic polyurethane fireproof and heat insulating material for the solar water tank, uniformly distributed and fine pores are formed, and the material is stable in heat insulating property, high in foaming speed and convenient to use; sepiolite is added to a white material, calcium powder enables the prepared heat insulating material to have a good flameretardant effect and a fireproof function; a proper amount of gelatin powder is added to the white material, the problem of poor flexibility of the heat insulating material can be effectively solved,and the prepared heat insulating material is convenient to use; a proper amount of tributyl phosphate is added to the white material, the problem of higher water absorbency of the heat insulating material can be effectively solved, and the prepared heat insulating material is low in water absorption.

Description

technical field [0001] The invention relates to the field of polyurethane thermal insulation materials, in particular to a polyurethane organic fireproof 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 insulat...
