burotsukuisoshianeto content emulsion composition and its production method and water foundation treatment agent and water baking type paint composition for porous backing material

摘要

This invention in the water one liquid type polyurethane brush revetment medicine which utilizes burotsukuisoshianeto chemical compound, advancing the improvement of the polyurethane emulsion for the water one liquid coating flux, furthermore to make the coating film efficiency improve in the paint of the emulsion, is assured to be something which utilization development as a foundation treatment agent of that emulsion, this invention to react, porimeritsuku MDI (a1) with nonionic characteristic polar group content high-molecular poly- all (a2) at the block medicine (C) blockading the isoshianeto basis, to form the burotsukuporiisoshianeto component (A), in the reaction system, organic poriisoshianeto (b1) with high-molecular poly- all (b2) and carboxyl group content anionic characteristic low-molecular glycol (b3) reacting, it produced carboxyl group content isoshianeto basic terminal urethane prepolymer (B), the carboxyl group at the counteragent (D) after making neutralize, it made the reaction blend water emulsify, at the chain extended medicine (E) did the chain extension reaction and made the high building a bridge type polyurethane resin form, it is the burotsukuisoshianeto content emulsion composition.
