Abstract

The invention relates to an environmental-protection and high-flame retardation PU foam material for PU foam material for air-conditioned bus lavatory covers, and a preparation method thereof. The foam material is formed by isocyanate and combined polyether polyester according to a mass ratio of 1:1.6, wherein the combined polyether polyester is prepared by using polyether polyol, polyether polyol 2, polyether polyol 3, polyester polyol 1, polyester polyol 2, polyurethane silicone oil, a catalyst 1, a catalyst 2, water and a flame retardant. The preparation method comprises the following steps: preparing the combined polyether polyester, and mixing the combined polyether polyester with the isocyanate to prepare the foam material. The foam material has very high flame retardation performance, is friendly to surrounding environment and has no pollution to the surrounding environment.
