Title:
SOLID DISPERSION, PREPARATION METHOD THEREFOR, CHAIN-EXTENDED POLYURETHANE USING SAME, AND EPOXY RESIN COMPOSITION COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/216700
Kind Code:
A1
Abstract:
The present invention relates to a solid dispersion, a preparation method therefor, a chain-extended polyurethane using same, and an epoxy resin composition comprising same and, more particularly, to a solid dispersion in which an inorganic or organic material-derived isotropic or anisotropic substance is used as a dispersoid and dispersed at room temperature in a solid-phase dispersion medium such as polyols and sugars, whereby the dispersion can be easily stored and used, reduce transportation cost, prevent or alleviate the aggregation or precipitation caused during the storage of products, with the results of working efficiency improvement and processing cost reduction, and, when applied to polyurethane, can increase strength and provide an improved strength, compared to conventional curing agent, a preparation method therefor, a chain-extended polyurethane using same, and an epoxy resin composition comprising same.
