Abstract

Abstract:

A quaternary copolymer water emulsion （denoted as PBMAA） and its natural drying film are firstly obtained with methyl methacrylate （MMA）， butyl acrylate （BA）， acrylic acid （AA） and acrylamide （AM） as monomers. Then， Kevlar-1313 of aramid （denoted as K-1313） is added to modify the copolymer （denoted as K-PBMAA） and the adding ratio is optimized in order to improve the strength and wear resistance of this film. The prepared solid nano-SiO₂ （denoted as S-SiO₂） and hollow nano-SiO₂ （denoted as H-SiO₂） are also added into K-PBMAA respectively to prepare nanocomposite leather finishing agents （denoted as S-SiO₂/K-PBMAA and H-SiO₂/K-PBMAA） that are applied for finishing sheepskin. It is found that the thermal decomposition temperature of the coating increases from 404 ℃ to 411 ℃ and the mechanical properties increases from 4.03 MPa to 8.67 MPa when K-1313 and nano-SiO₂ are introduced at the same time.
