Thermal-insulation composite material, and preparation method and applications thereof

Abstract

The invention discloses a thermal-insulation composite material, and a preparation method and applications thereof. The thermal-insulation composite material is prepared from a natural mineral material and an inorganic material with infrared reflection characteristics via combination; the natural mineral material is adopted to form a nanometer microporous structure to coat the surface of the inorganic material; the natural mineral material comprises at least one ingredient selected from attapulgite with a layer chain structure, montmorillonite with a layered structure, kaolinite with a layeredstructure, and fibriform aedelforsite; the inorganic material comprises at least one ingredient selected from rutile, calcined kaolinite, and zirconite. The thermal-insulation composite material is prepared from the natural mineral material and the inorganic material via combination, is excellent in flame resistance, high temperature resistance, and thermal insulation effect, is suitable for hightemperature thermal insulation field, is nontoxic, is safe, and is friendly to the environment, can be used in fields such as industry, building, and daily life.

Description

technical field [0001] The application relates to the field of thermal insulation materials, in particular to a thermal insulation composite material and its preparation method and application. Background technique [0002] China is a country with a relative shortage of energy, but the energy consumption per unit of GDP output value is 4-6 times higher than that of developed countries. In the field of industry, construction, and daily life, whether it is electric furnaces, boilers, industrial heat pipes, oil pipelines, heating pipes, etc., all of them do not need insulation treatment, and the insulation materials currently used are either high thermal conductivity , or is combustible. The most commonly used thermal insulation materials, such as asbestos, rock wool, glass fiber, aluminum silicate fiber, etc., not only have poor thermal insulation performance, but also belong to Class I or Class II carcinogens. Studies have shown that if all materials with flame-retardant pr...
