摘要

Abstract

An acrylate emulsion(AE)was prepared via semi-continuous seed emulsion polymerization using methyl methacrylate(MMA)and butyl acrylate(BA)as the main monomers,and 4-hydroxybutyl acrylate(4-HBA)as a post-crosslinking monomer.The effects of the 4-HBA content on the emulsion properties,as well as the structure and properties of the latex film,were investigated by nanoparticle size analyzer,viscometer,Fourier transform infrared spectrometer(FT-IR)spectrometer,thermogravimetric analyzer(TGA),and differential scanning calorimeter(DSC).The application of AE on decorative paper was also studied.The results showed that as the4-HBA content increased(≤5%),the monomer conversion rate and latex particle size showed no significant changes.4-HBA successfully participated in the emulsion copolymerization.When the 4-HBA content was 3%,the crosslinking density,72 h water absorption,maximum thermal degradation temperature,glass transition temperature,tensile strength,and elongation at break of the room-temperature latex film(LF)were 53.9%,4.67%,405.6℃,17.59℃,15.99 MPa,and 244%,respectively.After heat treatment at 160℃,the crosslinking density,water resistance,thermal stability,and mechanical properties of LF were improved.Furthermore,after AE modified with 3%4-HBA impregnation,the tensile strength and elongation at break of the impregnated film paper were 27.0 MPa and 15.2%,respectively,which were 15.0 MPa and 13.4 percent point higher than those of the base paper,and its bonding strength in the decorative wood-based panel was 0.472 MPa.
