Lightweight thermal insulation decoration panel and preparation method thereof

Abstract

The invention relates to a light heat preservation decoration panel which sequentially comprises a heat preservation layer, a sound insulation layer and a decoration layer from the inner side to the outer side, the heat preservation layer, the sound insulation layer and the decoration layer are integrally connected, a notch is formed in the outer side of the heat preservation layer, the sound insulation layer is filled and formed in the notch, and the heat preservation layer and the sound insulation layer comprise flush outer side end faces. The decorative layer is formed and attached to the outer side end face, the heat preservation layer is made of a light porous ceramic material, the sound insulation layer is made of a nano aluminum-magnesium sound insulation material, and the decorative layer is a glaze surface. In addition, the invention further provides a preparation method of the light heat preservation decoration panel, and the preparation method comprises the steps of manufacturing the heat preservation layer, manufacturing the sound insulation layer, manufacturing the decoration layer and the like. The technical scheme of the invention has the technical effects of light weight, heat preservation, fire prevention, water prevention, high strength, sound insulation and aging resistance with a decorative surface.

Description

technical field [0001] The invention relates to a lightweight thermal insulation decorative panel, a preparation method and a product thereof. Background technique [0002] The exterior wall insulation system of buildings is a very important part of energy-saving buildings and is widely used in construction projects at home and abroad. The existing insulation boards mainly include EPS boards, XPS boards, PU boards, phenolic boards, foam concrete boards, and rock wool. board etc. The veneer layer is inorganic board, metal board, stone board and ceramic board with various coatings, and the veneer is directly bonded to the insulation layer material with polyurethane glue or epoxy glue. [0003] These materials mainly have the following disadvantages: [0004] 1. The veneer is not a lightweight material, the volume is large, and it cannot be lightweight. [0005] 2. The thermal insulation layer is made of organic materials, which has the problems of poor durability and poor f...

AI Technical Summary

Problems solved by technology

[0004] 1. The veneer is not a lightweight material and has a large volume, so it cannot be lightweight

[0005] 2. The insulation layer is made of organic materials, which has the problems of poor durability and poor fire resistance

Although the combination of adhesive anchors is usually used, the anchors must be anchored on the veneer, so the supporting structure system and construction process are very complicated

[0007] 4. The sound insulation effect of the veneer needs to be improved

[0009] 1. The durability of the system is short. The design service life of the external wall insulation project is 25 years. Whether the commonly used organic insulation materials can be used for 25 years remains to be tested, while the inorganic insulation has a high water absorption rate and a large shrinkage rate, which affects the actual service life

[0010] 2. The safety performance is worrying. At present, the most commonly used external wall insulation materials are still organic materials, which have poor fire performance, and there are fire safety hazards in the process of construction and use.

[0011] 3. The construction process is complicated, and there are many hidden dangers in quality. The external wall insulation technology has very strict requirements on the construction level. If you are not familiar with the construction method and technical requirements, or the workers have a low level of technical operation, and the construction management is not strict enough, it is easy to cause serious problems. quality problems

[0012] 4. The cost of the system is high, and there are many construction procedures for the external wall thermal insulation system. When thermal insulation mortar is used as the thermal insulation layer, it is generally divided into three (or even more) plastering, and each plastering needs to be done after the previous plastering layer has hardened Then, an anti-crack layer needs to be installed outside the insulation layer, and a protective layer of mesh cloth or steel wire mesh should be installed, and finally the decorative surface coating should be done.
