摘　　要：以植物油、非铵盐类表面活性剂为原料,制得一种环境友好型防结块剂,通过模拟堆压加速结块法对施用该防结块剂复混肥的防结块效果进行了测定。结果表明,当m(防结块剂)∶m(复混肥)=5∶1 000,防结块剂组成为m(聚乙二醇2000+聚二甲基硅氧烷)∶m(聚山梨酯B)=1∶2且m(复配表面活性剂)∶m(植物油)=1∶100时,复混肥的最小结块率可达到9.0%,优于机油-胺类防结块剂。An environmentally friendly anti- caking agent product was prepared with vegetable oil and non-ammonium salt surfactant as raw materials. Anti- caking efficacy of the product was tested by accelerated compression stacking simulation method. Test results showed that in case the mass ratio of the materials is m（ anti- caking agent product） ∶ m（ blended fertilizer） = 5∶ 1 000,and mass ratio for composition of the anti-caking agent product is m（ PEG 2000 ＋ PDMS） ∶ m（ polysorbate B） = 1 ∶ 2 and m（ blended surfactants） ∶m（ vegetable oil） = 1 ∶ 100,the caking ratio achieves the lowest as 9. 0%,which is better than that of conventional anti- caking agents made of machine oil and ammonium compounds.
