Thermal insulation decoration board with high mechanical strength

Abstract

The invention relates to a thermal insulation decoration board with high mechanical strength. The thermal insulation decoration board with high mechanical strength comprises a slat, wherein the slat comprises a base layer and a thin film layer, the base material is one of gypsum, foamed glass, foamed cement or foamed ceramic, alkali-resistant glass fibers are uniformly mixed in the base material;the base material comprises an upper surface, a lower surface, edges all around and corners; the corners are rounded corners, the lower surface can be directly contacted with a to-be-decorated wall surface, rubber buffer cushions respectively cover the edges all around and the corners of the base material, an aluminum alloy metal layer is arranged on the upper surface of the base material, the thin film layer is laid on the metal surface of the aluminum alloy; the thin film layer comprises a decoration layer, an anti-static layer and a flame retardant layer; the decoration layer is made from aPVC plastic decoration thin film, the anti-static layer is made from a PE static thin film, and the flame retardant layer is one of glass fibers and EVA resin. Compared with the prior art, the thermal insulation decoration board provided by the invention has relatively high mechanical strength, the situation that the decoration board is smashed easily in a mounting process is reduced, mounting efficiency is effectively improved, structure is simple, and generalization performance is strong.

Description

technical field [0001] The invention belongs to the field of building wall decoration materials, in particular to a thermal insulation decorative board with high mechanical strength. 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 pat...

Problems solved by technology

[0003] With the application of decorative panels more and more widely, there are more and more requirements for the performance of decorative panels. The sound insulation effect of decorative panels mainly depends on the material of the substrate. Simple gypsum or wood-based decorative panels are thermal insulation 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

[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 undoubtedly increases the thickness of the decorative board. Excessively increased thickness will occupy a large amount of limited space, resulting in an increase in decoration costs. Nowadays, gypsum board or foamed glass is usually used as the base material and the surface of the base material used A metal layer is provided, and decorative films with various functions are laid on the surface of the metal layer to achieve the purpose of decoration and enhance the flame retardancy of the decorative board to a certain extent, but the base material of gypsum board and foamed glass are easy to be brittle when installed. If the slag is cracked, it is easy to collide with each other in the process of installing the decorative panels in strips, causing the base material to break, which in turn affects the decorative effect and installation progress
