Abstract

The invention discloses transparent polystyrene with the capacity scale of 50,000 tons or above as well as production equipment and process of the transparent polystyrene. The main component of the obtained transparent polystyrene product is as follows: n is the degree of polymerization, and the range of the n is 600-7000, and the n is different along with different types of products. The transparent polystyrene has good transparency, the Vicat softening point is 85-106 DEG C, the tensile strength of the transparent polystyrene is 40-55 Mpa at normal temperature, and the transparent polystyrene is a thermoplastic material. The molecular structure contains a small amount of macromolecules with a special structure, and a considerable amount of hydrocarbon micromolecules are contained in gaps of the macromolecules, so that certain slippage can be generated among the macromolecules, and the material has good transparency and mechanical properties compared with products obtained by other process production methods. The process waste water is basically not generated in the production process, all the raw materials are recycled, a small amount of generated process waste gas reaches the standard and is discharged after being condensed and adsorbed by special equipment, and good environment-friendly, energy-saving and consumption-reducing effects can be achieved.

Description

Technical field[0001]The present invention relates to the technical field of polystyrene materials, specifically a transparent polystyrene and production equipment above 50,000-ton capacity, and its production equipment, processes.Background technique[0002]Polystyrene refers to a polymer synthesized from a styrene monomer. Due to the characteristics of polystyrene, good rigidity, easy processing molding, dimensional stability, insulation, etc., plus low price, widely used in light market, packaging, electrical, toys, construction and other industries. However, universal polystyrene also has a disadvantage of impact resistance, making it restrictions. Currently producing polystyrene uses initiators to increase polymerization rate and regulating polymer molecular weight distribution to produce high quality polystyrene. According to the actual production application experience, the product produced by the initiator technology has better optical properties, mechanical properties, temper...
