A kind of production process of polystyrene insulation sandwich panel

Abstract

The invention relates to a production process of sandwich panels, in particular to a production process of a heat preservation polystyrene sandwich panel. The production process of the heat preservation polystyrene sandwich panel aims to achieve the technical purposes that the continuous machining efficiency is high, the bonding molding effect is good, and the fireproof property, heat preservation property and durability are all improved compared with an existing product. Through the production process of the heat preservation polystyrene sandwich panel, the finished heat preservation polystyrene sandwich panel is produced by combining a color steel plate roll I, a color steel plate roll II, a polystyrene plastic extrusion plate, alumina silicate fibers and other materials through the steps A-G. By means of the heat preservation and fire retarding performance of the alumina silicate fibers and alumina powder, the fireproof property and heat preservation property of the heat preservation polystyrene sandwich panel are greatly improved; through the peeling and grinding treatment on the polystyrene plastic extrusion plate, the bonding molding effect is improved; and the production process has the advantages of being high in continuous machining efficiency, good in bonding molding effect, quite high in practicability and suitable for application and popularization.

Description

technical field [0001] The invention relates to a production process of a sandwich panel, in particular to a production process of a polystyrene thermal insulation sandwich panel. Background technique [0002] At present, the materials of line boards widely used in house decoration on the market are wood, gypsum, stainless steel and plastics, etc., and the most frequently used plastic materials are polystyrene materials, and polystyrene extruded boards ( XPS) is the most widely used. Polystyrene extruded board is a material that is continuously extruded and foamed by a special process, so the hard film formed on the surface is uniform and flat, and the internal completely closed-cell foam is continuous and uniform, forming a honeycomb structure. , so it has the characteristics of high compression resistance, light weight, non-water absorption, airtight wear resistance and non-degradation, and its strength, heat preservation, and water vapor penetration resistance have been g...
