Building exterior wall heat preserving decorative composite plate and manufacturing process thereof

Abstract

The invention discloses a heat insulation and decoration clad plate for the outer wall of buildings. The structure of the clad plate from top to bottom successively is a polystyrene foam plastic board, a polyurethane layer and a polyvinyl chloride board. The manufacture technique is that: the polystyrene foam plastic board and polyvinyl chloride board are cut into pieces with the same specification; a well-blended polyurethane foaming agent is daubed or sprayed on the polystyrene foam plastic board; the polyvinyl chloride board is tidily clasped on the polystyrene foam plastic board daubed or sprayed with the polyurethane foaming agent; air is given to press the clasped polystyrene foam plastic board and polyvinyl chloride board by a tooling compound machine. The pressed clad plate is the finished product. The clad plate disclosed by the invention has the advantages of light weight, good decorative effect, low cost, water resistance, acid and alkali resistance, flame retardancy as well as simple and convenient construction, safe use, diversified colors and patterns, meanwhile, the invention functions well in the heat insulation, thermal insulation, decoration and protection of the buildings and is widely applicable to the installation and application of various buildings.

Description

Technical field [0001] The invention relates to a wall material for the construction industry, in particular to a thermal insulation decorative composite board for the exterior wall of a building and a manufacturing process thereof. Background technique [0002] At present, in the construction industry, in order to achieve the thermal insulation and decoration effect of the building, it is generally used to paste the polystyrene foam board on the outer wall of the building through glue or cement, and then apply it to the polystyrene foam board. The practice of smearing cement and pasting decorative tiles or painting with colored paint. This approach has many shortcomings. First, the decorative tiles are easy to fall off, posing a threat to pedestrians and making them unsafe. The second is that the color paint may be bleached or peeled off after being exposed to wind and rain, making it unsightly. Third, the construction process is complicated, the labor intensity of workers is hi...

Problems solved by technology

There are many disadvantages in this approach. First, the decorative tiles are easy to fall off, posing a threat to pedestrians and unsafe

The second is that the color paint will be discolored or peeled off after being exposed to wind and rain, which is not beautiful

Third, the construction process is complicated, the labor intensity of the workers is high, and the cost is high

Fourth, the doors and windows are often permeable, causing pulverization or cracking of building materials and reducing the service life of buildings
