Imitation shale rock building thermal insulation decorative board with three-dimensional effect and preparation method thereof

Abstract

The invention provides an imitation shale rock building thermal insulation decorative board with a three-dimensional effect and a preparation method thereof. The preparation method thereof includes the steps that glass raw materials are mixed with nano calcium carbonate, through high temperature ejection, molten glass is blown into microspheres, when the surfaces of the glass microspheres are notfully cured, ultrafine shale rock powder is sprayed to deposit, hollow glass microspheres fixedly with the ultrafine shale rock powder are obtained and prepared into paste and coated on a flame retardant substrate, a stone imitation plate forming layer is formed after drying and adhered onto the flame retardant substrate, and the imitation shale rock building thermal insulation decorative board isobtained. According to the imitation shale rock building thermal insulation decorative board with the three-dimensional effect and the preparation method thereof, the technical problems such as bad painting quality of stone imitation paint of decoration boards on the exterior wall and poor three-dimensional effect of stone imitation in appearance are solved, prepared imitation stone plates play two effects of stone imitation and thermal insulation, the ultrafine shale rock powder is dispersed evenly, uniform dispersion of the shale rock powder / the hollow glass microspheres improves the verisimilitude of stone imitation, spherical packing increases the stereoscopic sensation of stone imitation, and exterior wall facing is attractive and diverse.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a three-dimensional effect imitation shale stone building thermal insulation decorative board and a preparation method. Background technique [0002] At present, with the continuous growth of the world's energy demand, my country's energy demand has also ushered in a peak, especially in the construction industry, the proportion of energy demand is increasing day by day, and with the improvement of people's living standards, building energy consumption will eventually exceed Industry has become the industry with the largest energy consumption among all industries. In order to meet the needs of building energy conservation, the building material structure strives to insulate the inner and outer walls of the building, and reduce the energy consumption required to maintain a comfortable temperature inside the building, thus promoting the development of building thermal ins...
