Preparing silane as comonomer for waterborne traffic-marking paints

Tuesday, 14 July 2015

Styrenesulfonyltrimethoxysilylpropyl thioether (STEP) was synthesised as a silane containing comonomer for preparation of environmentally friendly waterborne traffic-marking paint, which has fast dry, abrasion resistance, and long term durability.

Then, the latex particles with a polyacrylate core and a polysilane shell were prepared by semi continuous seeded emulsion polymerisation. Several key polymerisation reaction conditions such as the STEP concentration, feeding sequence and the acrylates/silane ratio were detailedly discussed.

Also the optimal condition to prepare stable core-shell particles was selected and a proper preparation process was established. The as-synthesised particles were characterised by TEM and laser light scattering. The clear core-shell structure of the particles could be observed through analysis TEM. In addition, the obtained results manifested that silanes had been grafted on the surface of the polyacrylate particles and they distributed on the outmost layer of the particles. Finally, the surface hydrophobicity of the film formed by latex particles was investigated by the water absorption ratio measurement. The results suggest the developed latex particle provided with a fair water-repellency property.

The study is published in: Progress in Organic Coatings, Volume 85, August 2015, Pages 92-100.
