Description
Technical Field
The invention belongs to the field of plastic particle manufacturing, and particularly relates to an anti-impact polypropylene particle and a preparation method thereof.
Background
Styrene thermoplastic elastomers are the largest volume thermoplastic elastomers available, which behave like rubbers and are therefore frequently used for the preparation of elastomeric materials or impact-modifying compositions. Styrene-butadiene-styrene block copolymer (SBS) is a kind of styrene thermoplastic elastomer with the largest output and the most application at present, has plasticity of plastics and elasticity of rubber, has excellent tensile strength and processability, can keep good mechanical property in low temperature environment, and is suitable for being used as an impact resistance agent to be added into plastic products. Because of its existing large capacity, the finished product is cheap, convenient to control the cost.
Polypropylene (PP) is nontoxic, odorless, good in moldability, small in relative density, good in heat resistance, electrical insulation and excellent in mechanical properties, and is widely applied to the fields of machinery, automobiles, food packaging and the like. However, polypropylene has poor impact resistance and is very sensitive to notch and low temperature environments, and the defects greatly limit the application range of polypropylene. When a product with higher impact resistance requirement is manufactured, the single polypropylene resin can hardly meet the use requirement, so that an impact resistance component needs to be added for modification so as to expand the application.

The technical scheme adopted by the invention for solving the technical problems is as follows: an impact-resistant polypropylene particle comprises the following substances in parts by mass: 60-90 parts of polypropylene resin, 20-40 parts of SBS thermoplastic elastomer, 2-6 parts of dispersant and 3-7 parts of lubricant.
The dispersant is one or more of triethyl hexyl phosphoric acid, methyl amyl alcohol, polyacrylamide and fatty acid polyglycol ester.
The lubricant is one or more of paraffin, polypropylene wax, zinc stearate, stearic acid, ethylene bis stearamide, polyethylene wax and oxidized polyethylene wax.
A preparation method of impact-resistant polypropylene particles comprises the following steps: weighing 60-90 parts of polypropylene resin, 20-40 parts of SBS thermoplastic elastomer, 2-6 parts of dispersant and 3-7 parts of lubricant according to the mass parts, and banburying in a banbury mixer at the banburying temperature of 165 ℃ for 10-20 min; and after discharging, adding the material mass into a double-screw extruder through a feeder to perform extrusion granulation, wherein the extrusion temperature is 180 ℃, and the screw rotation speed is 80-120 rpm.
The invention has the beneficial effects that: the SBS thermoplastic elastomer is used as an impact-resistant component to modify the polypropylene material, so that the performance defects of poor impact resistance and sensitivity to low temperature and gaps of the polypropylene material are effectively overcome, and meanwhile, the SBS thermoplastic elastomer is low in price and effectively controls the production cost.
