Abstract

The invention discloses a thermal insulation waterproof daub and a preparation method thereof. The preparation method comprises the following steps of putting sodium silicate aqueous solution, a mildew preventive, a dispersing agent, an ester alcohol and functional fiber into a mixing tank with mixed liquor of styrene-acrylic emulsion, a coupling reagent and a wetting agent; starting a stirrer, wherein the stirring speed is 120-130r / min; after mixing for 2-3 hours, adding a thickener; adding hollow vitrified microbeads or hollow glass microbeads, aluminium silicate, ceramic sand, glue for building and polyphenyl granule while stirring at 50-60r / min, and stirring for 1-2 hours to obtain the thermal insulation waterproof daub. The thermal insulation waterproof daub has low density and good heat insulation performance, is paste, and can be directly used in site construction without any pretreatment measures such as adding water and stirring; the daub can form an integral thermal insulation layer on the surface of a wall and can be firmly combined with the surface of the wall, and no cavities exist between the thermal insulation layer and a wall body base layer; the formed external thermal insulation system of an exterior wall has a simple structure, is convenient to construct, and has short construction period and low expenses of labor.

Description

technical field [0001] The invention belongs to the field of architectural coatings, more specifically, the invention relates to a thermal insulation and waterproof cement and a preparation method thereof. Background technique [0002] In recent years, architectural reflective and heat-insulating coatings have been widely used as a new type of functional architectural coating in hot summer and warm winter, hot summer and cold winter regions. In hot summer and cold winter regions, on the exterior walls of some special buildings, such as energy-saving blocks (such as concrete blocks with core-hole insulation boards, aerated concrete blocks, etc.) that do not require external wall insulation systems, their matching The application of thermal insulation putty forms a building reflective thermal insulation coating-thermal insulation putty system, which can not only meet the requirements of building energy-saving design, but also play the role of reducing wall surface temperature...
