Thermal insulation material of solar water tank and preparation method thereof

Abstract

The invention relates to the technical field of solar heat preservation, in particular to a thermal insulation material of a solar water tank and a preparation method of the thermal insulation material. The thermal insulation material comprises the following components: isocyanate, dimethyl ether, amino polyether modified polysiloxane, ethylene glycol ether resin, glycerol polyether resin, a catalyst, a flame retardant, a foaming agent, glass fiber, an anti-aging agent and deionized water. The invention adopts a manufacturing method of pouring well-mixed materials into a thermal insulation material layer of a water tank of a solar water heater, and the method is simple and easy to implement, reduces the production cost, ensures the complete sealing property of the whole thermal insulationlayer and can reduce the heat loss; at the same time, the problem of size distortion of the thermal insulation material is effectively solved by adding the glass fiber into the thermal insulation material; in addition, the addition of the anti-aging agent and the inorganic flame retardant greatly improves the service life and the safety performance of the thermal insulation material. The thermal insulation material provided by the invention has good thermal insulation property and a good flame-retardation effect.

Description

technical field [0001] The invention relates to the technical field of solar thermal insulation, in particular to a thermal insulation material for a solar water tank and a preparation method thereof. Background technique [0002] With the increasing shortage of energy and the increasing pressure on environmental protection, countries around the world have begun to promote the development of renewable energy, among which solar energy is the most widely used and developed renewable energy with the best development prospects, and has been widely used in various industries , the solar water heater industry is one of them. As an inexhaustible clean energy source, solar energy has been paid more and more attention by people, and among them, 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. Existing thermal insulation materials for water ...
