Abstract

The invention discloses preparation of a styrene light diffusing agent. Fluorine-containing monomers such as heptafluoropropyl trifluorovinyl ether are introduced in styrene polymerization for a polymerization reaction, and then the styrene light diffusing agent is obtained.

Description

technical field [0001] The invention relates to a light diffusing agent, in particular to the preparation of a styrene-based light diffusing agent. Background technique [0002] Light-diffusing material refers to an optical material with a certain light transmittance and haze, which can convert point light source and line light source into line light source and surface light source, so as to achieve the effect of uniform distribution of incident beam light intensity. It is widely used in flat panel display, lighting engineering , laser, projection imaging and other technical fields. Today, with the maturity of high-power light-emitting diode chip manufacturing technology and its wide application in automotive lighting, signal lights, outdoor display screens, and indoor and outdoor lighting, the demand for LED light-diffusing particles is increasing rapidly. [0003] CN102702637 relates to a polystyrene composition with high light transmission and high shading, which is comp...
