The invention discloses an automobile interior ceiling with high sound absorption and insulation performance, and relates to the technical field of automobile interiors, the automobile interior ceiling comprises a fabric layer, a non-woven fabric layer and a functional layer which are sequentially arranged from inside to outside, the functional layer comprises a gum aluminum film layer, a polyurethane plate layer and a glass fiber felt layer, and all the layers are directly bonded through an adhesive. And the functional layers are bonded by adopting a non-isocyanate polyurethane adhesive. The bio-based non-isocyanate is adopted to replace isocyanate, the low-carbon and environment-friendly effects are achieved, the sorbitol-based non-isocyanate polyurethane adhesive, the sucrose-based non-isocyanate polyurethane adhesive, the modified lignin-based non-isocyanate polyurethane adhesive and the like are adopted to replace an adhesive prepared from isocyanate, and the adhesive prepared from the isocyanate is not prone to cracking. Raw materials influencing the environment are prevented from being adopted in the production process, meanwhile, petroleum resources are saved, and harm during production of the automobile roof is reduced.
