| description | The invention discloses a hydrolysis-resistant high-strength polyurethane composition for a photovoltaic frame, the hydrolysis-resistant high-strength polyurethane composition comprises a polyol component and an isocyanate component, the polyol component comprises polyether polyol, aromatic hydrolysis-resistant polyester polyol, a chain extender, a catalyst, a defoaming agent, an internal release agent and an impregnating compound, and the isocyanate component is polyphenyl polymethyl isocyanate. Compared with the prior art, the invention has the following beneficial effects: aromatic hydrolysis-resistant polyester polyol is added into the raw materials of the polyurethane composition and is matched with conventional polyether polyol for use, so that the water resistance of the polyurethane composition is improved, and meanwhile, the mechanical properties of a cured material are excellent; a proper impregnating compound is selected, and through formula design, the mixing viscosity of a polyurethane resin syst |
