Description
Technical field
The present invention relates to paint field, particularly relate to a kind of organic silicon modified aqueous polyurethane coating.
Background technology
Aqueous polyurethane coating refers to does not have organic solvent, uses the polyurethane coating that water is prepared as dispersion system.Due to its high-environmental, high-decoration, high-wearing feature, high anti-stick, splitting resistance, and relatively wide construction temperature scope, development at home and abroad rapidly, is widely used.But after aqueous polyurethane film forming, there is certain hydrophilicity, therefore water resistance is general not high; Aqueous polyurethane film mainly relies on the reactive force such as hydrogen bond and Van der Waals force and base material to combine, and therefore, sticking power is generally unsatisfactory.
Modification organosilicon being used for urethane is an important channel of improving urethane and organosilicon material single-material performance deficiency, and method of modifying directly adds organosilicon to urethane as properties-correcting agent.Along with going deep into of research, the application of organic silicon modified polyurethane is increasingly extensive.
But current organosilicon aqueous polyurethane coating, its weathering resistance, water tolerance are not good enough, and the low requirement that can not meet society of hardness, needs research further and improve.
