Abstract
The invention discloses a PU board for an automobile. The PU board for the automobile is prepared from the following raw materials in parts by weight: 5 to 7 parts of polyether polyol, 5 to 8 parts of benzoic anhydride polyester polyol, 3 to 8 parts of graphite, 3 to 8 parts of activated carbon, 6 to 9 parts of kieselguhr, 3 to 5 parts of stearic acid, 10 to 15 parts of natural organic fiber, 5 to 10 parts of ceramic fiber, 1 to 3 parts of mineral fiber, 2 to 6 parts of foaming agent, 1 to 3 parts of plasticizer and 2 to 6 parts of flame retardant. The PU board for the automobile has the advantages that the weight is light, the strength is great, the stability is enhanced, the sound absorbing effect is remarkably improved and the peculiar smell can be removed.
Description
technical field [0001] The invention belongs to the field of auto parts, and in particular relates to a PU board for automobiles. Background technique [0002] The sound absorption and sound insulation in the car is mainly realized by the special material of the ceiling. As one of the parts with the largest internal surface area of the passenger car, the car interior ceiling is an important sound-absorbing and sound-insulating component. However, the existing PU board has a single function and the sound absorption effect is not good. good. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a PU board for automobiles, which is light in weight, high in strength, enhanced in stability, significantly improved in sound absorption, and capable of removing peculiar smells. [0004] The technical scheme of the present invention is: a PU board for automobiles, consisting of the following raw materials in parts by weight: 5-7 pa...
