Preparation method of polypropylene plate with good impact resistance

Abstract

The invention discloses a preparation method of a polypropylene plate with good impact resistance. The preparation method comprises the steps that raw materials are extracted, wherein the raw materials include polypropylene resin, foaming agent, nucleating agent, propylene polymer, propylene-ethylene copolymer, phase solvent, light shield agent and antioxidant; the polypropylene resin, foaming agent, propylene polymer and propylene-ethylene copolymer are melted in the condition of 200 DEG C, a melt body is obtained, then a nucleating agent and the phase solvent are added in the melt body, the melt body is kept for 10 min after stirring and mixing, and added with the light shield agent and the antioxidant when the temperature falls to 160 DEG C, the melt body is extruded through an extruding machine after being kept for 15 min, pressed into a plate and cooled, and the finished product is obtained after cutting. Through the method, the impact resistance of the polypropylene plate is increased by improving the composition of the product and changing its composition structure, the strength of the impact resistance of the polypropylene plate is 10 times that of the impact resistance of an ordinary pure polypropylene plate, and damage to the plate caused by impact shock can be effectively avoided.

Description

technical field [0001] The invention relates to the field of polypropylene board preparation, in particular to a preparation method of a polypropylene board with good impact resistance. Background technique [0002] Polypropylene has the characteristics of good mechanical properties, non-toxicity, heat resistance, chemical corrosion resistance, low relative density and easy processing and molding. It has a wide range of applications, ranging from urban water supply and drainage systems to small packaging. Figure, because of its excellent characteristics, most anti-corrosion equipment adopts polypropylene sheet as its lining structure for anti-corrosion, but the impact resistance of ordinary polypropylene sheet is relatively weak, and it is easy to be impacted during transportation and installation. The impact will cause deformation and damage to the material. Therefore, the development of a polypropylene sheet with good impact resistance can effectively prevent the above pro...
