Multifunctional green building material

Abstract

The invention discloses a multifunctional building material having fireproofing, heat insulating and sound insulating functions to overcome the defects of poor heat insulating and sound insulating effects of existing building materials. The green building material comprises a fireproof layer arranged as an inner layer, a sound insulating layer arranged as an outer layer and a heat insulating layer arranged between the fireproof layer and the sound insulating layer, wherein bonding layers are arranged to connect the heat insulating layer with the fireproof layer and connect the heat insulating layer with the sound insulating layer. The multifunctional green building material has a good heat insulating performance, the heat conduction coefficient is 0.01-0.05 W / (m*K), the material has very good heat insulating and energy saving effects and a good fireproof performance, the fireproof duration limit is more than 3 h, and the material meets A level fireproof standards, so the multifunctional green building material has the characteristics of good fireproof property, good sound insulating performance, great reduction of noise influences, good durability, good resistance to a high temperature and a low temperature, and good resistance to corrosion and weather.

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. This application is a divisional application of a multifunctional green building material (2015106493685). 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.
