The invention discloses a novel bumper material and an automobile bumper thereof. The bumper material comprises, by weight, 35-55 parts of polypropylene, 2-10 parts of trichloroethyl phosphate, 5-15 parts of thermoplastic polyurethane, 3-10 parts of butadiene rubber, 4-12 parts of polyamide, 3-11 parts of ethylene propylene rubber, 3-11 parts of polyethylene, 4-10 parts of shear-thickening fluid, 10-16 parts of polyisophthaloyl metaphenylene diamine fibers, 1-6 parts of antistatic agents, 1-4 parts of antioxidants, 4-10 parts of dispersing agents, 1-5 parts of plasticizers and 1-5 parts of ultraviolet absorbents. The novel bumper material has the advantages of low shrinking ratio, high flowability, toughness, strength, breaking elongation and heat distortion temperature and excellent weather resistance and paint performance. When an automobile is slightly collided, the bumper cannot fracture. Compared with an existing bumper material, bending modulus, tensile strength, hardness and melt flow rate are greatly improved, and in addition, low-temperature impact resistance and chemical resistance are remarkably improved.
