Abstract

The invention discloses a PP plastic used for an automobile bumper and a preparation method thereof. The plastic is composed of, by weight, 100 parts of PP resin, 10-20 parts of phenolic resin, 15-30parts of nitrile butadiene rubber, 10-20 parts of nano sodium carbonate, 5-10 parts of mineral fibers, 3-5 parts of silicon nitride fibers, 0.5-2 parts of a lubricant, 0.5-1.5 parts of an antioxidant,1-3 parts of a coupling agent, 0.5-1.5 parts of a stabilizer, 0.5-2 parts of a modifier, and 1-3 parts of a processing aid. Through the special formula and synergistic effect, the components have great compatibility. The PP plastic has high strength, high anti-impact effect, high tensile strength and bending strength, is anti-wearing, weather-resistant and heat-resistant, is not liable to deform,age and crack, has good stability, and can be widely applied to automobile bumpers.

Description

technical field [0001] The invention belongs to the technical field of plastics, and in particular relates to a PP plastic for automobile bumpers and a preparation method thereof. Background technique [0002] PP, also known as polypropylene, is a semi-crystalline material. It is harder and has a higher melting point than polyethylene (PE) plastic. PP resins have excellent moisture absorption resistance, acid and alkali corrosion resistance, and solubility resistance. Because plastic has the advantages of light weight, no rust, and good insulation, it is one of the fastest-growing varieties of general-purpose thermoplastics. PP resin has certain special requirements in the fields of chemical industry, building materials, home appliances, automobiles, etc., but because PP has large spherulites, grain boundary defects and cracks are prone to appear at the spherulite interface, causing embrittlement. PP has the disadvantages of low modulus, low impact strength, and poor comp...
