Abstract

The invention discloses an environment-friendly high-efficiency all-water-blown rigid polyurethane external heat-preservation material and a preparation method thereof. The environment-friendly high-efficiency all-water-blown rigid polyurethane external heat-preservation material is prepared by performing high-speed stirring, foaming and curing on the main raw materials of polyether polyol, isocyanate, a composite catalyst, diatomaceous earth, a nanometer oxide and distilled water. The material and the preparation method thereof have the advantages that the material is free of low-boiling hydrocarbon chlorofluorocarbon and a hydrochloroflurocarbon compound, and is all-water-blown and environment-friendly, and the damage to an ozone layer and the greenhouse effect are avoided; all-water rigid polyurethane foam plastics is effectively improved by utilizing the diatomaceous earth and the nanometer oxide, so that the shortcomings of high viscosity, low flowability, large cells caused by non-uniform foaming, slightly high thermal conductivity, friability and weak strength of foams, and the like of the all-water rigid polyurethane foam plastics are overcome, and the heat-preservation performance, strength and heat resistance of the all-water rigid polyurethane foam plastics are improved; and compared with like products, the material has remarkable technical advantages and economic advantages, an environment-friendly high-efficiency heat-preservation material is provided for the energy saving of a building, and can be widely applied to the field of buildings, and huge economic benefits and social benefits can be produced.

Description

Technical field: [0001] The invention discloses a novel environment-friendly all-water-foamed rigid polyurethane high-efficiency external thermal insulation material, and also discloses a manufacturing method of the thermal insulation material, belonging to the technical fields of building energy-saving material production and building energy conservation. Background technique: [0002] my country is a large country with complex climate characteristics, such as the severe cold in the Northeast and the middle reaches of the Yangtze River in hot summer and cold in winter, which makes the energy consumption of building materials in my country very large. The energy consumption of keeping warm in winter in the northern region accounts for 47.3% of the total energy consumption in the country. However, due to the problems of materials, technology and workmanship, the heating energy consumption per unit area of ​​traditional buildings in my country is 2 to 3 times that of developed...
