Preparation and properties of high-strength porous hydrophobic lipophilic materials
The hydrophobic and oleophilic materials are produced by compounding ultrafine silicate as the main agent with suspending agent,pore-making agent,modifier and other additives.The porosity,compres-sive strength,relative oil-water permeability,and oil-water separation properties of the materials were in-vestigated.The results show that the water phase contact angle of the material is as high as 152°.The po-rosity is 68.5%,and the compressive strength is more than 5 MPa.The oil phase of the material is 4～5 times of the permeability of the water phase.The material has obvious separation effects on oil-water mix-tures with different viscosities,different oil phase states and different oil content rate.
