Preparation of Hydroxyl Acrylic Emulsion and Its Application in the Leather Finish
A kind of hydroxyl acrylic emulsion was prepared.The effects of different hydroxyl mass fraction on the properties of hydroxyl acrylic emulsion two-component film and application performances in leather finish were studied.The results showed with the increase of hydroxyl mass fraction,the breaking strength of the film rises and elongation at break of the film decreases.At the temperature of 25℃and-15℃,the flexural resistance of leather finishing samples becomes worse with the increase of hydroxyl mass fraction.When the leather finish layer is embossed under high temperature and hight pressure,the plate release property,cut-through resistance and embossing retention are satisfactory.Meanwhile,the surface feeling of the leather finish layer is good.
