Abstract

The invention discloses a high-strength high-strain low-heat-conductivity-coefficient thermal-insulation / sound-insulation / fireproof integrated board and a preparation method thereof. The high-strength high-strain low-heat-conductivity-coefficient thermal-insulation / sound-insulation / fireproof integrated board is composed of a vacuum thermal-insulation material and a coating outside the vacuum thermal-insulation material, wherein the coating is made from a high-strength high-strain cement-base composite material. The total thickness of the thermal-insulation / sound-insulation / fireproof integrated board is 14-30mm. The high-strength high-strain cement-base composite material is composed of mixing water (the water cement ratio is 0.20-0.25), fibers (accounting for 1-2 vol%), and the other components in percentage by mass: 25-43% of cement, 7-14% of silica fume, 7-26% of calcium powder, 7-22% of fly ash, 19-26% of sand, 0.019-0.038% of modifier and 2.962-2.981% of water reducing agent. The product has wide application range, thereby greatly widening the application range of the architectural energy-saving thermal-insulation material.

Description

technical field [0001] The invention relates to the technical field of load-bearing building thermal insulation materials, in particular to a method for preparing a high-strength, high-strain, low-thermal conductivity thermal insulation, sound insulation and fireproof integrated board. Background technique [0002] At present, building insulation materials are mainly divided into three categories: organic insulation materials, inorganic insulation materials, and insulation materials composited with inorganic gelling materials and insulation aggregates. At present, in the domestic market, more than 80% of building insulation materials are still organic insulation building materials, of which the most commonly used are EPS insulation boards, XPS insulation boards (extruded polystyrene insulation boards) and PU (polyurethane foam) insulation boards, Phenolic insulation boards, etc. These materials have low thermal conductivity and good energy-saving effect. The application of t...
