摘要

以二异氰酸酯异福尔酮为聚合单体,2,4-二氨基苯磺酸钠盐为亲水性单体,纳米二氧化硅为表面粗糙剂,在乙腈体系中采用沉淀聚合法制备了一种表面粗糙、尺寸不同(1 ~ 12 μm)的聚脲微球,用于水性聚氨酯哑光皮革涂料。考察了二异氰酸酯异峰酮和2,4-二氨基苯磺酸钠盐的负载、h2o /乙腈的体积比和纳米sio2的添加阶段对涂层粒径和表面粗糙度的影响,以获得优异的哑光效果。结果表明,亲水性单体的加入可以减小聚脲微球的粒径,提高其在水中的再分散性,而混合溶剂中乙腈比例的增加和聚合单体的负载可以增大聚脲微球的粒径。作为表面粗化剂,随着纳米二氧化硅负荷量的增加,微球的表面粗糙度增大,颗粒尺寸增大。在反应体系混浊阶段加入纳米二氧化硅,可使聚脲微球的表面粗糙度达到最大。粒径(1 ~ 2 μm)、表面粗糙度高的聚脲微球具有较好的消光效果,制备的水性聚氨酯涂料光泽度可调至1.6°(60°入射角)以内。

Silica-Embedded Polyurea Microspheres with Rough Surface for Matte Leather Finishing
A type of polyurea microspheres with rough surfaces and different sizes (1-12 μm), which was used for waterborne polyurethane matte leather coating, were prepared by precipitation polymerization in H 2 O/acetonitrile system, using isophorone diisocyanate as polymerized monomer, 2,4-diaminobenzenesulfonic acid sodium salt as hydrophilic monomer and nano-SiO 2 as surface roughener. The effect of the loading of isophorone diisocyanate and 2,4-diaminobenzenesulfonic acid sodium salt, the volume ratio of H 2 O/acetonitrile and the addition stage of nano-SiO 2 on the particle size and surface roughness were investigated so as to achieve the excellent matte effect of the coating. The results indicated that the adding of hydrophilic monomer can reduce the particle size of microspheres and improve its re-dispersibility in water, while the increase of the proportion of acetonitrile in the mixed solvent and the loading of polymerized monomer can enlarge the size of the polyurea microspheres. As surface roughener, with the increase of nano-SiO 2 loading, the surface roughness and the particle size of microspheres increase. When nano-SiO 2 is added at the stage of the reaction system getting turbid, the maximum surface roughness of polyurea microspheres can be achieved. Polyurea microspheres with particle size (1-2 μm) and high surface roughness have better matting effect, and the gloss of the prepared waterborne polyurethane coating can be adjusted to less than 1.6° (60°-incident Angle).
