Problems solved by technology

At present, conventional external wall internal thermal insulation systems, such as the construction industry standard "JG / T 159-2004 external wall internal thermal insulation board" of the Ministry of Construction, and the disclosed technology, all use polystyrene foam (polystyrene for short) as thermal insulation materials. Therefore, its thermal insulation performance is average, but it is easy to catch fire. When it catches fire, it produces a lot of black smoke and toxic gas (carbon monoxide CO), which seriously threatens the lives and property safety of the people. Polystyrene is used as internal insulation, which does not meet the requirements of fire protection. Disabled by fire in the 1990s, needs improvement

Abstract

The invention discloses a phenolic aldehyde foam board inner thermal insulation system for outer walls and a construction method thereof. The phenolic aldehyde foam board inner thermal insulation system for outer walls comprises a binder layer (7) coated on a foundation wall (1) of the outer wall, an integral skin phenolic aldehyde foam board (2) adhered to the binder layer (7), a plastering inner layer (3) adhered to one side of the integral skin phenolic aldehyde foam board (2), a piece of fiberglass mesh cloth (4) adhered to the outside of the plastering inner layer (3) and a plastering outer layer (5) adhered to the outside of the fiberglass mesh cloth (4). The phenolic aldehyde foam board inner thermal insulation system for outer walls disclosed by the invention has good thermal insulation performance, combustion performance up to a non-combustible grade, smoke toxicity up to standard safety grade, intensity up to or exceeding that of polystyrene inner thermal insulation board for outer walls (construction industry standard JG/T 159-2004 of inner thermal insulation board issued by Ministry of Housing and Urban-Rural Development of the People's Republic of China), as well as non-toxicity, good environmental performance, air permeability, no cracking, convenient material source, energy-saving construction and wide application.

Description

technical field [0001] The invention relates to an external wall internal thermal insulation system of an enclosure structure in the technical field of building energy conservation, in particular to an external wall internal thermal insulation system of a phenolic foam board and a construction method. Background technique [0002] The external wall insulation of a building directly affects the energy consumption of the building. The external wall insulation system is an important factor in achieving building insulation. At present, conventional external wall internal thermal insulation systems, such as the construction industry standard "JG / T 159-2004 external wall internal thermal insulation board" of the Ministry of Construction, and the disclosed technology, all use polystyrene foam (polystyrene for short) as thermal insulation materials. Therefore, its thermal insulation performance is average, but it is easy to catch fire. When it catches fire, it produces a lot of bla...
