Abstract

The invention relates to an inorganic fiber heat-insulating paste material and a preparation method thereof. The inorganic fiber heat-insulating paste material is characterized by consisting of the following components: coal ash of secondary level or above, colored sand, sepiolite fibers, polyropylene fibers, an acrylic emulsion, cellulose ether, a film-forming additive, vitrified micro bubbles and the balance of water, and the total percent of the components is 100. The inorganic fiber heat-insulating paste material has the advantages of being the same in service life as a building, superior in fire resistance (A1-grade combustion level), low in heat conductivity, stable in performance, light in dry unit weight, good in sound-proof effect, free from influencing indoor secondary Guangzhou decoration, convenient and quick in construction, particularly remarkable in performance on specially-shaped walls, free from cracks, elastic, incombustible, fire-proof, air-permeable, hydrophobic, single-component, air-hardening, and convenient for construction, and truly avoiding water adding for blending on 'industrial processing' sites. As the raw materials are coal ash and other energy-saving and environment-friendly materials, the inorganic fiber heat-insulating paste material conforms to the national industrial policy and has a very good development prospect. The inorganic fiber heat-insulating paste material is used for heat insulation of civil and industrial building walls, and the thicknesses of the insulating layers are determined by thermotechnical computation according to the current building energy-saving design standards or the building energy-saving requirements and manufacturing technology requirement of the city.

Description

technical field [0001] The invention relates to an inorganic fiber thermal insulation paste and a preparation method thereof. Background technique [0002] my country's thermal insulation materials are roughly divided into two categories, namely inorganic thermal insulation materials and organic thermal insulation materials. Inorganic thermal insulation materials include glass wool, rock wool board, inorganic thermal insulation mortar, foamed cement board, etc. These materials have better thermal insulation and fire prevention performance. Organic insulation materials include EPS board, XPS insulation board, polyurethane foam insulation board and phenolic board, etc., which have good thermal insulation performance and thermal insulation performance, but poor fireproof performance. In recent years, the product structure of my country's thermal insulation industry has undergone significant changes, among which lightweight materials, green environmental protection materials an...
