Abstract

The invention relates to a production process of extruded sheets, in particular to a production process of a polystyrene extruded sheet. The technical problem to be solved is to provide a production process of a polystyrene extruded sheet, with the process good in processing efficiency and good in forming effect and the sheet better than an existing product in moisture resistance, warmth retention and durability. The production process includes the steps A to F, polystyrene and raw materials are heated and plasticized and are extruded by two plastic extruders, and the finished polystyrene extruded sheet is produced by shearing through a slitting device and a cross-cutting device. Through scientific proportioning of the raw materials and by optimizing and improving internal structure of the polystyrene extruded sheet, the moisture resistance, warmth retention and durability of the polystyrene extruded sheet are greatly improved, and the polystyrene extruded sheet has high practicality and is suitable for popularization and use.

Description

technical field [0001] The invention relates to a production process of an extruded plastic plate, in particular to a production process of a polystyrene extruded plastic plate. Background technique [0002] At present, the materials of line boards widely used in house decoration in the market are wood, gypsum, stainless steel and plastic, etc., and the most commonly used plastic material is polystyrene, and the application of polystyrene is divided into It is molded polystyrene foam (EPS) and extruded polystyrene foam board (XPS). It 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 high compression resistance, light weight, non-absorbent, It is airtight, wear-resistant and non-degradable. Compared with molded polystyrene foam (EPS), its strength, heat preservation, and water ...
