Paper as a common advertising carrier,because of its low cost,easy to control,detailed content,targeted,covering a wide range of advantages by the majority of businesses,business leaders favor.However,the paper is prone to damp,yellow,faded,difficult to long-term preservation,and relatively thin,easy to be broken,and other shortcomings,limited its application in the advertising industry.The paper with self-cleaning coating was prepared by polydimethylsiloxane (PDMS),hydrophobic silica,toluene as the basic raw materials.The prepared solution was sprayed on the surface of advertising paper,soaked in fluorosilane solution after curing at room temperature,and then heated and dried to obtain advertising paper with self-cleaning and anti-graffiti properties.Scanning electron microscopy (SEM) was used to measure the surface morphology and roughness of the substrate.The change of wettability on the surface of advertising paper was detected by the contact angle measuring instrument.Mark marker was used to test its anti-graffiti property.To test the tensile strength of the coating with the electronic universal testing machine,the size increased from 5.5MPa to 14.8MPa.
