Abstract

A formula of an insulation material of a water tank of a solar water heater is disclosed. The formula includes, by weight, 60-70 parts of glyceryl glucoside polyether glycol, 5-10 parts of chitosan, 8-15 parts of dimethyl methylphosphonate, 8-15 parts of titanium dioxide, 5-10 parts of aluminum silicate and 2-10 parts of calcium chloride. The insulation material is used on the surface of the watertank of a solar water heater, and has a high heat absorption rate, and improved heating efficiency. The material overcomes the shortcomings of large shrinkage after foaming molding, avoids deformation of the water tank, and ensures the thermal insulation performance of the water tank of the water heater.

Description

technical field [0001] The invention relates to thermal insulation materials, in particular to a formulation of thermal insulation materials applied to solar water heater water tanks. Background technique [0002] At present, the insulation materials that can be used as water tanks mainly include polyurethane foam, phenolic foam, and microfiber. Polyurethane foam is made by mixing isocyanate and polyether composition and pouring it into a mold or water tank cavity for foaming. The polyether composition contains polyether polyol, foaming agent, catalyst, stabilizer, etc. Polyurethane foam material is currently recognized as the best thermal insulation material in the world. It has the advantages of small thermal conductivity, high compressive strength, good adhesion, and easy processing. It is widely used in electrical appliances, refrigerators and freezers, building walls, industrial pipelines and transportation. The thermal insulation of refrigerated vehicles is a new grow...
