    • PURPOSE: A light diffusion acryl resin composition is provided to obtain high haze, high light transmittance, high luminance and low surface resistance. CONSTITUTION: The light diffusion acryl resin composition comprises 100 parts by weight of a poly(methyl methacrylate)-based acryl resin; 0.1-15 parts by weight of a polystyrene-based bead-shaped light diffusion resin; 0-50 parts by weight of an acryl-based impact modifier; 0.3-5 parts by weight of an antistatic agent; and 0.005-0.2 parts by weight of a fluorescent whitening agent. Preferably the polystyrene-based bead-shaped light diffusion resin comprises 50-100 mol% of styrene and 0-50 mol% of poly(methyl methacrylate) and has an average diameter of 5-200 micrometers. Preferably the acryl-based impact modifier is has a core-shell structure; and the antistatic agent is at least one selected from the group consisting of cationic surfactants and anionic surfactants.
    • 目的:提供光散射丙烯酸树脂组合物以获得高雾度,高透光率,高亮度和低表面电阻。 构成:光扩散丙烯酸树脂组合物包含100重量份的基于聚(甲基丙烯酸甲酯)的丙烯酸树脂; 0.1〜15重量份的聚苯乙烯类珠状光扩散树脂; 0-50重量份的基于丙烯酸的抗冲改性剂; 0.3-5重量份的抗静电剂; 和0.005-0.2重量份的荧光增白剂。 优选地,基于聚苯乙烯的珠状光扩散树脂包含50-100摩尔%的苯乙烯和0-50摩尔%的聚(甲基丙烯酸甲酯),并且具有5-200微米的平均直径。 优选地,基于丙烯酸的抗冲改性剂具有核 - 壳结构; 并且所述抗静电剂为选自阳离子表面活性剂和阴离子表面活性剂中的至少一种。
