Inorganic fiber composite thermal insulation board for exterior wall and production method thereof

Abstract

The invention discloses an inorganic fiber composite thermal insulation board for an exterior wall. The thermal insulation board is fixed on an exterior wall of a building and comprises transverse edge strips, vertical edge strips, a shingle, an inner wallboard and filling material; the two transverse edge strips are parallelly arranged up and down as a top surface and a bottom surface of the heat insulation board; the two vertical edge strips are respectively fixed at two ends of the transverse edge strips as two side surfaces of the heat insulation board; the transverse edge strips and the vertical edge strips are spliced to form a main skeleton; the shingle and the inner wallboard are installed at two sides of the main skeleton to splice into a hollow structure; the filling material is inorganic fiber filling material and inorganic fiber spraying adhesive; the inorganic fiber filling material and the inorganic fiber spraying adhesive are synchronously sprayed and fills the hollow structure. The invention also discloses a production method of the heat insulation board; the method mainly comprises following steps: splicing a box body structure, fixing dies, spraying and filling, setting and dismounting dies. The invention relates to the field of buildings and provides an inorganic fiber composite thermal insulation board having better heat insulation performance for exterior walls and a production method of moulding spraying and filling.

Description

technical field [0001] The invention relates to the field of construction, in particular to an inorganic fiber composite external wall insulation board and a production method thereof. Background technique [0002] At present, my country's building energy consumption accounts for about 1 / 3 of the total energy consumption of the whole society. The living area of ​​heating cities in northern my country only accounts for 10% of the national urban living area, but building energy consumption accounts for 40%. The largest energy consumption of buildings in our country is heating and cooling. Compared with developed countries with similar climate conditions, the heating energy consumption per square meter of buildings in our country is about three times that of developed countries. my country is currently making every effort to promote building energy saving by 65%. standard. [0003] Therefore, the thermal insulation performance of the original building is extremely poor, and the...

Problems solved by technology

[0003] Therefore, the thermal insulation performance of the original building is extremely poor, and the energy consumption is too large. It is necessary to carry out thermal insulation and energy-saving renovation. One of the simple and effective means is the external insulation of the external wall.

However, due to lessons learned from the CCTV fire, the application of low-cost organic insulation materials such as expanded polystyrene, expanded polyurethane, and expanded phenolic formaldehyde in building insulation has been greatly restricted, among which flame retardancy and fire resistance are fatal flaws

[0004] However, among the inorganic insulation materials, one type is rock wool block or rock wool felt, which is easy to absorb moisture and fall off after long-term use, and the other type is inorganic insulation materials such as foamed perlite, foamed ceramics, foamed glass, and foamed cement, which are heavy In addition, the added external wall bears a large load and has a poor thermal insulation effect, and both types of thermal insulation materials require a large amount of adhesive to bond with the two side panels, which is costly and the durability of time needs to be tested
