Problems solved by technology

At present, most of the insulation materials used in high-rise buildings in my country are polymer organic foam insulation boards, which are easy to burn and have low noise reduction capabilities, and there are major problems in both production costs and environmental pollution. Environmental protection The problem has always been the direction advocated by the government, so there is an urgent need for a new material with low cost and low environmental pollution. After using glass powder and fly ash, it is found that the building panel composed of the combination of the two has poor alkali resistance and is easily corroded. And if the structural strength is weak, the yield rate is low, so it needs to be improved

Abstract

The invention discloses a heat-insulation and noise-reduction building panel for building a house. The heat-insulation and noise-reduction building panel is prepared from the following components in parts by weight: 100 to 300 parts of glass powder, 150 to 250 parts of fly ash, 3 to 7 parts of dispersant, 2 to 3 parts of foaming agent, 10 to 30 parts of binding agent, 30 to 60 parts of borax, 20 to 80 parts of glass fibers and 200 to 300 parts of water. The borax can be used for reducing the softening temperature of a sample so that the sintering temperature is reduced, and the borax plays animportant role in a foaming process. The panel prepared from the components has the advantages of heat insulation and noise reduction, and is prepared from waste materials of a power plant, so that the heat-insulation and noise-reduction building panel has great significance on environment protection.

Description

technical field [0001] The invention relates to a building panel, in particular to a thermal insulation and noise reduction building panel for building construction. Background technique [0002] In recent years, with the continuous prosperity and development of the economy, the economic construction is changing with each passing day, and high-rise buildings have sprung up in large, medium and even small cities. Because high-rise buildings are tall, have many floors, complex functions, and dense population, once a fire breaks out, the fire will spread rapidly, and it will be difficult to evacuate and fight the fire, which will inevitably lead to large losses and casualties. Therefore, governments all over the world have put forward strict requirements for materials such as flame retardancy, low flame, and low smoke emission in the fields of construction and transportation. At present, most of the insulation materials used in high-rise buildings in my country are polymer org...
