Abstract

The invention belongs to the technical field of polymer synthesis, and in particular relates to polyester-polyether polyol for a microporous PU (polyurethane) shoe sole and a preparation method of the polyester-polyether polyol as well as a PU shoe sole stock solution prepared from the polyester-polyether polyol and a preparation method of the PU shoe sole stock solution. The polyester-polyether polyol for the microporous PU (polyurethane) shoe sole is a copolymer of epoxypropane and ethylene oxide by taking aromatic polyester polyol as an initiator, and a hydroxyl value is 48 to 112mg KOH / g; the epoxypropane in a molecular chain accounts for 50 to 75wt percent, and the ethylene oxide accounts for 10 to 20wt percent. The polyester-polyether polyol provided by the invention is low in viscosity, high in end group activity, and narrow in molecular weight distribution, has the characteristics of being wide in formula process tolerance and good in dimensional stability in the preparation of microporous elastomeric materials, and has the characteristics of good mechanical properties such as high tear strength, high tensile strength, and high stretch rate of the polyester shoe sole stock solution and the properties of low viscosity and hydrolysis resistance of a polyether shoe sole stock solution, and the very good application value is achieved.

Description

Technical field [0001] The invention belongs to the technical field of polymer synthesis, and specifically relates to a polyester-ether polyol for microporous PU shoe soles, a preparation method thereof, and a preparation method of a PU sole stock solution and a PU sole stock solution prepared therefrom. Background technique [0002] Polypolyols currently used in PU shoe soles mainly include polyester polyols and polyether polyols. Polyester sole has the characteristics of high strength, good abrasion resistance, and good adhesion to the upper, and it occupies more than 80% of the market share of polyurethane sole materials. However, polyester sole materials also have their own shortcomings: poor hydrolysis resistance, poor temperature resistance, solid or high-viscosity liquid at room temperature, and inconvenient operation. The mechanical properties of polyether type sole materials are worse than polyester type, but due to its good hydrolysis resistance stability, it is liquid...
