Novel heat preservation material of solar water tank

Abstract

The invention relates to the technical field of solar heat preservation, in particular to a novel heat preservation material of a solar water tank. The heat preservation material comprises the following components: isocyanate, dimethyl ether, amino polyether modified polysiloxane, glycol ether resin, glycerin polyether resin, a catalyst, a flame retardant, a foaming agent, glass fiber, an anti-aging agent and deionized water. The novel heat preservation material adopts a manufacturing method of mixing the materials and pouring the materials into a heat preservation material layer of the solarwater heater tank, the method is simple and easy, the production cost is reduced, the complete sealing property of the entire heat preservation layer is endured, and heat loss is reduced; at the sametime, as the glass fiber is added into the heat preservation material, the problem of dimensional deformation of the heat preservation material is effectively solved; in addition, by adding the anti-aging agent and the inorganic flame retardant, the service life and safety performance of the heat preservation material are greatly prolonged and improved. The novel heat preservation material has better heat preservation performance and better flame retarding effect.

Description

technical field [0001] The invention relates to the technical field of solar thermal insulation, in particular to a novel thermal insulation material for a solar water tank. 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 tanks of solar water heater...
