The invention discloses a hydrophilic
resin coating material for calendaring
polyvinyl chloride (PVC) leather, which is formed by the following steps of proportioning parts by weight of polyatomic
alcohol compound, diisocyanate, chain extentor, hydrophilic chain extentor, salifying agent, hydrophilic flatting agent, hydrophilic
thickening agent, hydrophilic defoaming agent and deionized water, being prepared by
prepolymer, being chain extended by the
prepolymer, being neutralized and emulsified by the
polymer and the like. The hydrophilic
resin coating material for calendaring the PVC leather can resolve the problem that the
coating material on surface of the PVC leather is wet and extending. The hydrophilic
resin coating material can be prepared with existing equipment, thereby saving production cost. Treating effects of the hydrophilic resin
coating material for calendaring the PVC leather are identical with treating effects of corresponding
solvent products. Furthermore, compared with traditional
solvent products, the hydrophilic resin
coating material for calendaring the PVC leather is more excellent in scraping resistance, full touch, fine texture and the like.
