Embodiment 1

[0071] This embodiment provides a method for preparing a decorative insulation board, and the preparation method specifically includes the following steps:

[0072] (1) Spray a layer of vitrified microbeads in the mold to form a self-cleaning layer 1, and the surface of the vitrified microbeads is coated with TiO 2 Nano self-cleaning coating, TiO 2 The thickness of the nano self-cleaning coating is 1 μm;

[0073] (2) pour 10mm thick concrete slurry on the self-cleaning layer 1;

[0074] (3) Lay one deck metal mesh 3 and 1cm thick vitrified beads on the slurry surface successively, and vibrate the mold so that the metal mesh is embedded in the slurry;

[0075] (4) After the vibration is completed, the concrete slurry is cured at 5°C and the relative humidity is 50% under the curing conditions until it is solidified and formed, and the decorative surface layer 2 formed by the concrete slurry and the thermal insulation layer formed by the vitrified microspheres are obtained. 4...

Abstract

The invention provides a decorative insulation board with a self-cleaning function and a preparation method of the decorative insulation board. The insulation board comprises a self-cleaning layer, adecorative surface layer, an insulation layer, a bonding layer and a base layer which are sequentially stacked from top to bottom. The preparation method comprises the following steps that (I), a layer of mineral aggregate coated with a nano self-cleaning coating on the surface is laid on the bottom of a mold, and the self-cleaning layer is formed; (II), slurry is poured on the self-cleaning layer, a reinforcing material and a thermal insulation material are sequentially laid on the surface of the slurry, and the mold is vibrated so that the reinforcing material can be embedded into the slurry; and (II), curing is performed until the slurry is cured and molded, the decorative surface layer formed by the slurry and the insulation layer formed by the thermal insulation material are obtained,the decorative surface layer is subjected to hardening treatment, the insulation layer and the base layer are bonded through the bonding layer, and the decorative insulation board is obtained. The decorative insulation board with the self-cleaning function not only has high strength, good integrity and good insulation performance, but also is attractive in decoration effect and durable in use.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a thermal insulation board and a preparation method thereof, in particular to a decorative thermal insulation board with a self-cleaning function and a preparation method thereof. Background technique [0002] With the development of the economy and the progress of the society, the rapid development of the construction industry and the rapid improvement of the living environment, the requirements for building materials are getting higher and higher, and the external wall insulation is the focus of people's attention. Traditional external wall insulation technology often uses a single inorganic or organic insulation material, which not only cannot ensure the connection between the insulation layer and other layers, but also has no corresponding protection measures for the insulation layer, resulting in unsatisfactory insulation effects. Therefore, the use of single insulat...
