福建省改性塑料技术开发基地日前以高效低毒驱虫剂等为原料,制备出具有驱虫功能的母粒,采用该母粒制成的农用薄膜能够驱虫。据介绍,科研人员以高效低毒驱虫剂(氟虫隆、乙虫脒、双甲脒三种复配)、聚乙烯蜡分散剂、硅酸钙保温剂、硅烷偶联剂、紫外光吸收剂、乙烯-醋酸乙烯(EVA)树脂为原料,通过包覆分散、偶联、密炼共混、挤出切粒等工序,制备出具有驱虫功能的母粒,再将该母粒以3%～4%的比例添加到低密度聚乙烯树脂中,通过吹塑工艺制成薄膜。由于薄膜中驱虫剂的缓慢释
Fujian Province modified plastic technology development base recently with high efficiency and low toxicity insect repellent as raw material, prepared with the deworming masterbatch, the masterbatch made of agricultural film can deworming. According to reports, the researchers to efficient and low toxicity insect repellent (flubexone, acetamiprid, amitraz three complex), polyethylene wax dispersant, calcium silicate insulation agent, silane coupling agent, ultraviolet absorption Agent and ethylene-vinyl acetate (EVA) resin as raw materials to prepare masterbatch with de-worming function by coating, dispersing, coupling, mixing and extruding, % ~ 4% ratio added to the low density polyethylene resin, made by the blow molding process film. Due to the slow release of repellent in the film
