缓控释肥硅基膜材的制备与表征
Preparation and Characterization of Silicon Based Films with Slow/Controlled-release Fertilizers
摘要
Abstract
The silicon-based membrane of slow/controlled-release fertilizer was prepared by taking calcium magnesium phosphate fertilizer and silicon acrylic resin as the main raw material,and sodium methylsilicate as binder.Three kinds of coated urea were prepared by centrifugal coating and bottom spraying fluidized bed process,and their release characteristics were studied by hydrostatic test.The results showed that three kinds of coated urea could keep a complete sphere in water and had good water resistance,and the release periods were 60 d,79 d and 96 d,respectively.The morphological characteristics and structure of membrane materials were investigated using scanning electron microscopy,infrared spectroscopy and X-ray diffraction.Calcium magnesium phosphate fertilizer and silicon acrylic resin were used as film-forming materials,and sodium methylsilicate was used as a sealant and waterproof agent to participate in the film-forming reaction,effectively increasing the plasticity and toughness of the film materials.This composite material can be used as the cementing agent and coating agent of slow/controlled-release fertilizer.关键词
