Abstract

The invention relates to the technical field of a solar heat insulation material, in particular to a combined polyether polyol heat insulation material for a solar water tank and a preparation methodthereof. The combined polyether polyol heat insulation material is prepared from an ingredient A and an ingredient B, wherein the ingredient A is prepared from the following raw materials in parts byweight: 30 to 45 parts of polyether polyol 6001A, 30 to 45 parts of polyether polyol 7001, 11 to 15 parts of polyether polyol 403, 1 to 1.5 parts of foam stabilizing agents, 0.5 to 1.5 parts of deionized water, 2.0 to 3.0 parts of composite catalysts and 6 to 8 parts of cyclopentane; the ingredient B is prepared from the following raw materials of 105 to 115 parts of polymerized MDI and 20 to 30 parts of expanded graphite. The combined polyether polyol heat insulation material obtained through preparation has the advantages of relatively good flowability, relatively good heat insulation performance and proper system viscosity. The cyclopentane is used, so that the atmospheric ozonosphere damage can be avoided; the expanded graphite is used, so that the heat insulation effect can be improved.

Description

technical field [0001] The invention relates to the technical field of solar thermal insulation materials, in particular to a combined polyether polyol thermal insulation material for solar water tanks and a preparation method thereof. Background technique [0002] In recent years, solar water heaters have been developing rapidly, and have become a rising star that has attracted the attention of the industry with a high growth rate of 20-30% per year. There are several domestic solar energy production enterprises with large investment, many equipments and high output. The principle of the solar thermal insulation material used in it is a polyurethane thermal insulation material made by mixing polyether and isocyanate through a high-pressure impact of 100 bar using high-pressure infusion equipment. Polyurethane thermal insulation material is a very important synthetic material, with excellent physical and mechanical properties and chemical resistance, especially low thermal ...
