Abstract

The invention discloses a production method for high-thermal-insulation water-resistant polystyrene sandwich plates. The method includes the steps of producing colored galvanized steel plates; producing polystyrene foam plates; producing adhesives; producing sandwich plates; profiling the colored galvanized steel plates through an automatic forming machine, and then pressurizing and heating the colored galvanized steel plates on the upper surface and the lower surface and the polystyrene foam plates through the produced adhesives to obtain the polystyrene sandwich plates. The method is simple to operate, low in raw material price and low in production cost, and the produced sandwich plates are good in thermal insulation performance, excellent in flame retardancy, good in aging resistance and water resistance, light and efficient.

Description

Technical field: [0001] The invention relates to the field of building materials, in particular to a method for preparing a polystyrene sandwich panel with high thermal insulation and water resistance. Background technique: [0002] With the rapid development of my country's economy, higher requirements are put forward for the construction industry. The wall materials in my country's construction industry still use traditional clay bricks and tiles, resulting in waste of precious land resources and environmental pollution during the firing process. posed all sorts of insurmountable difficulties. According to the above-mentioned problems, the Ministry of Construction of the People's Republic of China proposed the reform policy of wall materials, and new building materials emerged in an endless stream. [0003] Polystyrene sandwich panels began to appear in China in the 1980s, and due to their excellent performance and wide range of uses, they have developed rapidly in just a...
