Abstract

The invention relates to a thermal-insulating anti-flaming building material and a preparation method thereof. The thermal-insulating anti-flaming building material comprises the following components by weight parts: 45 to50 parts of lightweight aggregates, 45 to 50 parts of inorganic gelled materials, 5 to 10 parts of toughening agents, 3 to10 parts of interface modifying agents and 0.5 to 2 parts of dispersing agents. The quick coagulating function and the closing function of the interface modifying agents are utilized to perform hole-closing treatment on the surfaces of the lightweight aggregates; fibrous inorganic whisker materials with big ratio of length to diameter are selected as the toughening materials; the defects of inferior thermal-insulating effect and fragile property of the inorganic thermal-insulating material are thoroughly overcome; all the raw materials of the thermal-insulating anti-flaming building material are selected from A-level anti-flaming materials and areexcellent in anti-flaming effect; and the production process for the thermal-insulating anti-flaming material is simple and short, is continuously operated, is easily performed and controlled and is beneficial to industrialized application.

Description

technical field [0001] The invention relates to the field of thermal insulation building materials, in particular to a building material with thermal insulation and flame retardant function and a preparation method thereof. Background technique [0002] my country's economy is developing rapidly, but the development of energy is relatively lagging behind. One of the best ways to solve the energy shortage is to save energy. Therefore, continuous research and development of energy-saving new materials is the country's long-term development strategy. Since building energy consumption occupies a large proportion in all energy consumption, more and more attention has been paid to it. Building energy saving mainly uses thermal insulation materials to reduce heat loss to ensure a constant indoor temperature, thereby reducing the energy used for heating or cooling. [0003] Due to the low thermal conductivity and good thermal insulation performance of organic thermal insulation ma...
