Abstract

The invention discloses a thermal insulation and facing integrated board and a production method thereof. A sludge foaming agent is mainly made of river sludge, a foam cement thermal insulation board is mainly made of the sludge foaming agent, cement and fly ash, and a flexible facing material is mainly made of modified sludge and coated to the thermal insulation board through the spray technology to obtain the thermal insulation and facing integrated board. According to the thermal insulation and facing integrated board produced through the production method, the thermal conductivity is less than or equal to 0.024 W / mk, the apparent density is less than or equal to 3.78Kg / m<2>, and the adhesive strength with cement mortar is 0.25-0.3 MPa. The thermal insulation and facing integrated board has the advantages of being good in thermal insulation and weather resistance, low in production costs, long in service life, simple in construction and the like and is applicable to insulation and decoration of a building exterior wall.

Description

technical field [0001] The invention relates to a decorative and thermal insulation integrated board and a preparation method thereof, in particular to a thermal insulation and decorative integrated board using river sludge as a main raw material and a preparation method thereof. Background technique [0002] With the acceleration of environmental governance of rivers, a large amount of sludge with high water content and rich in organic matter will cause serious secondary pollution if it is not treated in time during the process of river dredging. [0003] Traditional river sludge is mainly disposed of through incineration or landfill, and part of it is used for organic fertilizer processing or direct use. However, the cost of incineration or landfill treatment is high for a while, and it is often easy to cause secondary pollution. With the acceleration of the industrialization process and the aggravation of river water pollution, river sludge is rich in a large amount of h...
