Heat-storage, energy-saving and sound-insulation building material

Abstract

The invention provides a heat-storage, energy-saving and sound-insulation building material, and relates to the technical field of building materials. The heat-storage, energy-saving and sound-insulation building material comprises the following components in parts by weight: 25-30 parts of phase change cement, 20-25 parts of ceramic powder, 5-12 parts of expanded perlite, 3-5 parts of volcanic ash, 1-2 parts of slaked lime, 5-8 parts of recycled asphalt, 15-20 parts of rock wool, 5-10 parts of alkaline leaching bagasse pulp fibers, 3-5 parts of an inorganic phase change heat storage material, 1-2 parts of multi-walled carbon nanotubes, 5-10 parts of building wastes, 5-10 parts of old textile fibers, 3-5 parts of bamboo fibers, 3-5 parts of paraffin and 10-15 parts of polyurethane resin. Various waste resources are used and more environmentally friendly, the finished product can achieve organic and inorganic phase change heat storage, heat can be dissipated in a one-way mode in cooperation with the heat insulation performance of rock wool, the heat storage and heat release efficiency is improved, a hole structure is arranged in the finished product, the sound absorption and insulation capacity can be improved, and the whole product further has excellent strength, toughness, water resistance and flame retardant performance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a heat storage, energy saving and sound insulation building material. Background technique [0002] In the north of my country, in order to keep the building wall insulated and meet the national energy-saving index of 50%, it is adopted to add a layer of 110mm thick benzene board, 80mm thick foamed polyurethane board or extruded board to the wall structure, although it can play a role It has a certain heat preservation effect, but there are various problems such as flammability, toxicity, short service life, complicated construction, easy slipping, and poor bonding strength. At present, some building materials with phase change heat storage have appeared on the market, and their application to chemical raw materials is relatively large. Although the purpose of heat storage is achieved, various materials are not environmentally friendly and cannot well meet the needs of ...
