Problems solved by technology

[0004] Some traditional thermal insulation pastes are fireproof but not waterproof; some are fireproof and waterproof but have high thermal conductivity. Therefore, the preparation of fireproof, waterproof, low-carbon and environmentally friendly energy-saving thermal insulation pastes to solve the above problems has immeasurable development prospects
[0005] The Chinese patent No. 201210108965.3 discloses a high-performance nano-insulation paste, which uses a fibrous magnesium-rich clay mineral sepiolite wool, and adds active ingredients such as glass beads and airgel. The paste has good mechanical strength, and its thermal conductivity can reach 0.043W/m·K, but the use of traditional airgel powder is expensive a

Abstract

The invention belongs to the technical field of energy-saving and environment-friendly materials, and particularly relates to a building, silica aerogel fireproof, waterproof, environment-friendly thermal insulation paste for industrial energy conservation and thermal insulation and a preparation method of the paste. According to the thermal insulation paste, an aerogel precursor is added during preparation, silicon sol and organic silicon modified acrylic emulsion serve as binding agents, and the paste has the incomparable heat insulation performance compared with a traditional material. After the thermal insulation paste is dried, the high mechanical strength is achieved, and the fireproof A1 grade is achieved; besides, the paste has relatively good waterproof performance and low cost, and a novel material is provided for building energy conservation, environmental protection and industrial energy conservation.

Description

technical field [0001] The invention belongs to the technical field of energy-saving and environment-friendly materials, and in particular relates to a fireproof, waterproof and environment-friendly heat preservation paste prepared from an airgel precursor for building and industrial energy-saving heat preservation and a preparation method thereof. Background technique [0002] In recent years, the field of building energy conservation has gradually attracted people's attention. Traditional organic thermal insulation materials are bound to gradually fade out of the stage of thermal insulation materials due to their flammability, large amounts of harmful gases generated during combustion, and difficulty in degradation. Common inorganic thermal insulation materials, such as cement and lime paste, have high mechanical strength, but high thermal conductivity, poor thermal insulation effect, short hardening time, and large shrinkage. In addition, the weak link of building exterio...
