Abstract

The invention discloses a polypropylene material resistant to aging and impact at low temperature as well as a preparation method of the polypropylene material. The polypropylene material comprises the raw materials such as polypropylene resin, butadiene rubber, an ethylene-vinyl acetate copolymer, diethyl phthalate, triethylene glycol di-2-ethylhexoate(triglycol dioctate), dilauryl thiodipropionate, dibasic lead stearate, hexamethylenetetramine, tristearin, cobalt iso-octoate, ethyleneglycol dimethacrylate, a silane coupling agent KH550, erucicamide, hollow glass microspheres, andalusite powder and precipitated white carbon black. The butadiene rubber and the ethylene-vinyl acetate copolymer are added into polypropylene resin, so that the cold resistance of the polypropylene material is improved, and the resistance to impact at low temperature is enhanced; the hollow glass microspheres and the andalusite powder are added for combined utilization, so that the tensile strength and impact strength can be synergistically improved; through addition of triethylene glycol di-2-ethylhexoate(triglycol dioctate) and the like, the cold resistance of the polypropylene material is further improved; through addition of nanometer titanium phosphate, the aging resistance of the polypropylene material is improved under the joint action of zinc oxide, precipitated white carbon black and nanometer titanium phosphate.

Description

technical field [0001] The invention relates to a polypropylene material, in particular to an aging-resistant and low-temperature impact-resistant polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene is a thermoplastic resin produced by the polymerization of propylene, usually a translucent colorless solid, odorless and non-toxic. Due to the regular structure and high crystallization, the melting point can be as high as 167°C. It has the characteristics of heat resistance and corrosion resistance. In recent years, due to the rapid development of engineering modification technology of polypropylene materials, its application in the automotive field has become more and more extensive. However, as an important part of engineered polypropylene materials in the automotive field, automotive bumpers, various automotive interior parts, and instrument panels made of engineered polypropylene materials. However, due to the poor anti-agi...
