Description
Technical field
The present invention relates to technical field of macromolecules, relate to especially preparation method and the goods of a kind of leather organic silicon modified aqueous polyurethane.
Background technology
Along with the enhancing of people's environmental consciousness, material safety problem is all the more paid attention to, compound with more and more higher standard and the requirement of other daily necessitiess propositions such as adhesive, leather coating to packing.Aqueous polyurethane (WPU) is to adopt the polyaminoester emulsion of water as decentralized medium, except having solvent borne polyurethane excellent properties, also have the advantages such as use is simple, nontoxic, non-environmental-pollution, its product is successfully applied to the industries such as light textile, leather, timber processing, building, papermaking.But because aqueous polyurethane adopts water as solvent, the surface tension of WATER AS FLOW MEDIUM is too large, heat content is high, make that in its film forming procedure, surface spreading is poor, drying time is long, film forming and base material are compound poor, mechanical property reduction; And impel the hydrophilic radical of aqueous polyurethane stable dispersion in WATER AS FLOW MEDIUM, can cause aqueous polyurethane film forming poor water resistance and easily water suction; Difficulties in dispersion that when aqueous polyurethane emulsion dispersion, high-viscosity organic phase can cause, emulsion particle diameter is large and emulsion solid content is lower.
