A silicate exterior wall thermal insulation material

Abstract

The invention discloses a novel silicate external wall insulation material. The novel silicate external wall insulation material comprises a boundary layer, an insulation board and a facing layer. The boundary layer is used for bonding a wall surface base body with the insulation material. The insulation board is a silicate insulation board. The facing layer is sprayed onto an outermost layer of the insulation board. The novel silicate external wall insulation material provided by the invention has the following beneficial effects that polypropylene fibers are added into the boundary layer, so that the toughness and the tension resistance of the insulation material are improved, and not only is the good bondability between the insulation material and the wall surface base body ensured, but also cracking and disengaging of the insulation material can be prevented; the silicate insulation board has fire resistance and is low in heat conductivity coefficient, so that a good insulation effect can be achieved; and the insulation board is isolated from making contact with air through the facing layer, and the service life of the insulation material is prolonged.

Description

technical field [0001] The invention relates to building exterior wall materials, in particular to a silicate exterior wall thermal insulation material. Background technique [0002] At this stage, people from all walks of life are actively calling for the use of technological innovation, institutional innovation, industrial transformation, and new energy development to achieve an economic model and a way of life and work that save energy and reduce emissions. Accounted for a large proportion, and with the rapid development of urbanization, building energy consumption is also showing a trend of rapid growth. Therefore, building energy saving has become an important aspect that cannot be ignored in our energy saving and emission reduction. Among them, realizing energy saving by improving building thermal insulation capacity has become one of the most important energy saving measures at present. [0003] Building exterior wall insulation has been widely used as a technical me...

Problems solved by technology

[0003] Building exterior wall insulation has been widely used as a technical means of building energy saving, but at present, exterior wall insulation materials still have problems such as poor adhesion to the substrate, easy cracking, and poor insulation durability. In order to achieve the purpose of energy saving and emission reduction , and in order to ensure the long-lasting use of building insulation materials, we must continuously improve the production technology of external wall insulation materials to produce external wall insulation materials that meet market demand
