Abstract

The invention discloses transparent polystyrene with ultraviolet aging resistance and good yellowing resistance. The transparent polystyrene comprises the following components in parts by weight: 110 to 120 parts of styrene, 0.02 to 6.5 parts of a lubricant, 0.001 to 0.55 part of an antioxidant, 0.0001 to 0.55 part of a light stabilizer, 0.001 to 0.55 part of an initiator and 0.001 to 7.5 parts of a chain transfer agent. The light stability and the ageing resistance of a GPPS material for a light guide plate can be improved, particularly, the material has good stability on ultraviolet and near ultraviolet high-energy light rays, and the microscopic stability of the material can be ensured even if the GPPS material is used for a long time lastingly; and the light aging resistance and the oxidation resistance of the material are improved, and the impurities which can generate decomposition and yellowing in the product are eliminated. Meanwhile, by optimizing the process technology and the formula technology, the rigidity and temperature resistance of the product are improved, and the application performance of the product is improved.

Description

technical field [0001] The invention relates to the technical field of polystyrene resin, in particular to a transparent polystyrene with ultraviolet aging resistance and good yellowing resistance and a preparation method thereof. Background technique [0002] Transparent polystyrene GPPS materials for optical applications are widely used in light guide plates of flat LED lamps and light guide plates of LCD liquid crystal components. At present, polystyrene materials have good light transmission and application applicability, and the products are easy to produce. Usually, under the premise of the production of general-purpose GPPS products by the bulk method combined with the use of special optical-grade polystyrene production formula and suitable production equipment, optical-grade GPPS products with high light transmission effects can be produced, but this through the bulk method GPPS products with high light transmittance formula in the polymerization process will appear...
