The invention belongs to the technical field of high polymer materials, and particularly relates to composite polyether for manufacturing a glass fiber composite material, and a preparation method and application thereof. The combined polyether for manufacturing the glass fiber composite material is prepared from polyether polyol A, polyether polyol B, polyester polyol C, a foam stabilizer, a foaming agent, a catalyst, a flame retardant and a coloring agent; according to the invention, by optimizing the formula structure and performance of the polyether product, the polyurethane material with excellent quality can be produced only by using the standardized isocyanate product, and can be compounded with glass fiber materials with various sizes and structures, so that the final product has good heat insulation performance and specific strength. |
