Abstract

A composite polyacrylic latex via
two stage seeded emulsion polymerization with low emulsifier content (0.5 wt.%)
was synthesized and characterized by means of particle size and zeta potential
analysis, FTIR and differential scanning calorimetry (DSC). The results
verified a very uniform particle size distribution and good electrostatic
stability. The different phases of the composite polymer were evidenced by DSC
analysis with two clear phase transitions. The application of the latex on
leathers as coating binder revealed good fastness levels to dry/wet rubbing and
water spotting. The synthesized composite latex was found to be good candidate
for producing cost-effective waterborne binders with good performance.

Synthesis and Application of a Low Emulsifier Content Composite Polyacrylic Latex for Leather Finishing

Abstract

Kompozit yapılı bir poliakrilik lateks, iki aşamalı
tohumlanmış emülsiyon polimerizasyonu ile düşük emülgatör içerikli (ağ. %0.5)
olarak sentezlenmiş; partikül boyutu ve zeta potansiyeli analizi, FTIR ve
diferansiyal taramalı kalorimetri kullanılarak karakterize edilmiştir. Elde
edilen sonuçlar lateksin çok homojen bir partikül boyutu dağılımına ve iyi
elektrostatik stabiliteye sahip olduğunu göstermiştir. Kompozit polimerin
farklı fazları DSC analizi ile iki net faz geçişi olarak ortaya konmuştur.
Lateksin mamul derilerde kaplama binderi olarak uygulanması sonrasında,
yaş/kuru sürtme haslıkları ile su damlası haslığı testlerinin iyi sonuçlar
verdiği gözlenmiştir. Sentezlenen lateksin, iyi performansa sahip, düşük
maliyetli su bazlı binderlerin üretimi için iyi bir aday olduğu tespit
edilmiştir.
