Preparation of co-polyurethane latex for cation fluoride acrylic.

The researchers studied cation fluoride acrylic co-polyurethane latex and its application in cotton fabrics.
with the improvement of people's living standards, the demand for textiles with special properties such as hydrophobicity is increasing rapidly. In a new study, using Span 80, Tween 80 and Tween 80 and Tween D3methyl chloride as composite emulsizers and (2-(acrylamide) ethyl) trimethyl ammonium were used in a semi-continuous seed emulsion polymerization process to synthesize cation fluoride copolymer milk particlesChloride as an cation monosome.
successfully confirmed cation fluoride acrylic co-polymers through FTIR, 1H NMR and XPS analysis. In addition, homogeneity latex particles with a distinct nuclear-shell structure (average particle size of approximately 132 nm) were observed through TEM analysis, and a stable positive charge (48 to 5 mV) was demonstrated on the surface of latex particles by ζ potential. Analysis.
It is excellent hydrophobic even at low concentrations
at the same time, the results show that the dose of methyl acrylate tetrofluoroesteride (DFMA) plays a vital role in the hydrophobicity of latex films, and the best hydrophobicity is identified at a dose of 10 g DFMA. In addition, cotton fabric finishing experiments show that after finishing with cation fluorofluoride acrylic copolymer emulsion, even at low concentrations, the treated cotton fabric also showed excellent hydrophobicity, water contact angle is greater than 130 degrees, electrostitectric absorption time is greater than 60 minutes.
