Decorative plate with heat preservation and thermal insulation

Abstract

The invention provides a decorative plate with heat preservation and thermal insulation. The decorative plate comprises a plate body, the plate body comprises a decorative plate base material and a thin film layer, the decorative plate base material comprises a gypsum plate layer and an aluminum alloy metal layer, the gypsum plate layer comprises an upper surface and a lower surface, the upper surface is provided with an aluminum alloy metal layer, the thin film layer is laid on the surface of the aluminum alloy metal layer, supporting columns are arranged in the gypsum board layer, are of a cylindrical I-shaped pier base structure, are spaced for a certain distance and are distributed in a rectangular array mode, cavity structures are formed among the supporting columns, the cavities arefilled with a heat preservation and thermal insulation material, the thin film layer comprises decorative film, an anti-static layer, a fire retardant layer and a waterproof layer, and the waterprooflayer is titanium dioxide thin film. The decorative plate has high heat preservation and thermal insulation, compared with the prior art, the space occupied by the decorative plate is reduced, the fire resistance and the self-cleaning capacity of the overall decorative plate can be comprehensively improved, and then the using range of the decorative plate is expanded.

Description

technical field [0001] The invention belongs to the field of building wall decoration materials, and in particular relates to a decorative board with thermal insulation performance. Background technique [0002] At present, the commonly used indoor wall decoration in the construction industry is mostly in the form of paint or decorative boards. Most of the decoration paints will encounter the pungent smell caused by the volatilization of chemical substances contained in the paint, and even the problem of excessive formaldehyde. It will take six months to a year to dissipate the volatilized chemical smell, and the inability to live will affect people's health. In recent years, decorative panels are often used for interior wall decoration, and decorative panels mostly use natural wood species to decorate veneers or artificial wood The decorative veneer is made of thin wood chips and pasted on the base material through tight wound cutting or rotary cutting. The decorative patt...

Problems solved by technology

[0003] As the application of decorative panels becomes more and more extensive, some requirements for the performance of decorative panels are also increasing. The sound insulation effect of decorative panels mainly depends on the material of the substrate. Simple gypsum or wood-based decorative panels The thermal effect is limited, and it is easy to cause the weight of the decorative board itself to increase, which increases the load-bearing burden of the building. It is inconvenient to install, and because of the large void ratio, fast water absorption and low moisture resistance, the base material is easily deformed and moldy after being damp. It has been used in places with high or low air humidity for a long time, but the flame retardant effect of the coating material is generally poor, and it is easy to deform when the temperature is high. When the indoor environment is dry, the surface film is easy to crack. The antistatic effect is poor and cannot reduce static electricity. Especially in the dry and cold areas of the north, the flame retardant and anti-static properties of decorative panels are required to be higher, resulting in poor usability of decorative panels

[0004] In order to enhance the thermal insulation effect of the decorative board, the existing treatment scheme usually adopts the structure of multi-layer superimposed materials, and sets the thermal insulation layer on the surface of the decorative board base material to solve the problem of poor thermal insulation of the decorative board, but This structure itself will undoubtedly increase the thickness of the decorative board. Excessively increased thickness will occupy a large amount of limited space, resulting in an increase in decoration costs. However, the thermal insulation materials used today have poor flame retardancy. There is an obvious deviation in the flame retardant ability of the decorative board, which makes the thermal insulation material on the base surface of the decorative board reduce the flame retardant performance of the entire decorative board, thereby reducing the comprehensive practical performance of the decorative board
