Abstract

The invention discloses impact polystyrene with the capacity scale of 50,000 tons or above as well as equipment and a production process of the impact polystyrene. More than 90% of the components of the rubber modified polystyrene product are represented by the formula, n is the polymerization degree, the range of n is 600-7000, and n is different along with different types of products; in addition to the main components, the rubber composition also contains 3-10% of butadiene rubber for modification, 0-7% of white oil, 0-1% of an additive of stearate, and a small amount of an organic residue such as a monomer (the total amount is 800 ppm or less). The modified polystyrene has good impact strength, the vicat softening point is 92-106 DEG C, the tensile strength of the modified polystyrene is 22-45 MPa at normal temperature, and the modified polystyrene is a thermoplastic material with good toughness. No process waste water is 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 subjected to condensation and adsorption treatment of special equipment, and the good environment-friendly, energy-saving and consumption-reducing effects can be achieved.

Description

technical field [0001] The invention relates to the technical field of polystyrene materials, in particular to impact-resistant polystyrene with a production capacity of 50,000 tons or more and its equipment and production process. Background technique [0002] Polystyrene refers to a polymer synthesized by free radical addition polymerization of styrene monomer. Polystyrene is widely used in the light industry market, packaging, electrical, toys, construction and other industries due to its hard quality, good rigidity, easy processing and molding, stable size, insulation and other characteristics, coupled with low price. However, general-purpose polystyrene also has the disadvantage of not being impact-resistant, which limits its application. To make general-purpose polystyrene impact-resistant, rubber has been introduced into it, i.e. modified polystyrene or high-impact polystyrene (HIPS). Rubber-modified polystyrene is an improvement to general-purpose polystyrene, and ...
