Foamed cement insulating material and posttreatment process thereof

Abstract

The invention belongs to the technical field of insulating materials for building walls, and particularly relates to a treatment fluid formula of a foamed cement insulating material and a posttreatment process of the foamed cement insulating material. The foamed cement insulating material is provided with a treatment fluid protective layer outside the insulating material, wherein the treatment fluid protective layer has a thickness of 0.3-2mm; an organic silicon water-repellent protective layer is arranged outside the treatment fluid protective layer; the organic silicon water-repellent protective layer has a thickness of 0.2-1mm; and the treatment fluid is composed of the following components: 50-100 parts of liquid sodium silicate or potassium silicate, 0-50 parts of lithium silicate and 10-20 parts of silicasol. According to the invention, the foamed cement insulating material can be prevented from powder shedding, the strength can be improved, the water absorptivity can be reduced, and the service life can be prolonged, wherein the strength can be improved by 20-220%, the volume water absorptivity can be reduced to 10% or below, and the service life can be prolonged 3-5 times.

Description

Technical field: [0001] The invention belongs to the technical field of thermal insulation materials for building walls, and in particular relates to a treatment liquid formula for foamed cement thermal insulation materials. Another object of the present invention is to provide a post-treatment process for the foamed cement insulation material. Background technique: [0002] Energy saving and emission reduction is a basic national policy of our country. Building energy-saving exterior wall insulation has been listed as a mandatory standard. At present, 80% of building energy-saving exterior wall insulation adopts the method of thin plastering of expanded polystyrene board exterior wall insulation. The advantages are: the cost is relatively low Low (high cost of flame retardant), less new technology content, easy to master; its disadvantages are: (1) layered construction, complicated process, high follow-up construction cost; (2) the thickness uniformity of plastering morta...

[0002] Energy conservation and emission reduction are the basic national policies of our country, and building energy-saving exterior wall insulation has been listed as a mandatory standard. At present, 80% of building energy-saving exterior wall insulation uses expanded polystyrene board The method of thin plastering for external wall insulation has the advantages of low cost (high cost of flame retardant), less new technology content, and easy mastering; its disadvantages are: (1) layered construction, complicated process, and high follow-up construction costs (2) The thickness uniformity of plastering mortar is not easy to control; (3) It is not easy to maintain on site, it has a large drying shrinkage and is easy to crack; (4) It is different from the expansion coefficient of the main body of the building, and it is easy to peel off; (5) It is different from the service life of the main body of the building The service life of the residence is generally 50 years, and the service life of the external insulation system is generally 20 years, facing the pressure of secondary renovation; (6) The external insulation layer has low density and low strength, and the decorative tiles and mosaics are easy to fall off There are security risks
