Insect-proof master batch, polypropylene composition thereof and preparation method of insect-proof master batch

The invention belongs to the technical field of high polymer materials, and discloses an insect-proof master batch, a polypropylene composition thereof and a preparation method of the insect-proof master batch. The insect-proof master batch is prepared from the following components in parts by weight: 60 to 75 parts of polypropylene carrier resin, 15 to 25 parts of modified silicon dioxide, 0 to 0.6 part of antioxidant, 0 to 0.5 part of lubricant and 6 to 10 parts of weather-proof agent. When the insect-proof polypropylene composition is prepared, volatilization and decomposition of a repellent in the processing process of an extruder can be effectively reduced, rapid volatilization of the repellent is prevented, and durability of the insect-proof effect is guaranteed; the light diffusion effect, the insect prevention effect and the irradiation resistance are good, and the lamp can be widely applied to the field of illumination. 本发明属于高分子材料技术领域，公开了一种防虫母粒、其聚丙烯组合物及其制备方法。本发明的防虫母粒按重量份数计，包括以下组分：聚丙烯载体树脂60～75份，改性二氧化硅
