Multifunctional green building materials

Abstract

The invention discloses multifunctional green building materials with functions of fire prevention, thermal insulation and sound insulation and aims to overcome the defect that current building materials are poor in thermal insulation and sound insulation effects. The green building materials comprise an inner fire preventing layer, an outer sound insulation layer and a thermal insulation layer between the inner fire preventing layer and the outer sound insulation layer, wherein the thermal insulation layer is connected with the fire preventing layer through an adhering layer, and the thermal insulation layer is connected with the sound insulation layer through an adhering layer. The multifunctional green building materials have the advantages that the building materials are good in thermal insulation performance, the heat conductivity coefficient of the building materials is 0.01-0.05W/(m*K), the building materials are good in thermal insulation and energy saving effects and good in fire preventing performance, the fire resistance duration of the building materials is larger than 3 hours, an A-level fire preventing standard can be reached, good fire resistance is achieved, a good sound insulation performance is achieved, noise influence can be reduced greatly, good durability is achieved, and the building materials are resistant to high temperature and low temperature and good in corrosion resistance and weather resistance.

Description

technical field [0001] The invention belongs to the new technology field of building materials, in particular to a multifunctional green building material with fire prevention, heat preservation and sound insulation. Background technique [0002] With the rapid growth of my country's national economy and the improvement of people's living standards, my country's construction industry has been overloaded, which has brought a series of energy and environmental problems. At present, building energy consumption has become the weakness of my country's economic development, and a large number of high energy consumption buildings have a huge potential energy crisis. Therefore, in order to achieve sustainable development of the construction industry, improvements in building materials are required to actively increase energy efficiency. [0003] For example, taking thermal insulation as an example, from the perspective of building materials, adding materials with thermal insulation...
