Research On High Performance Polypropylene Coating Resin

Solid packaging industry of coating grade polypropylene resin requirements increasing, but domestic poly coated polypropylene resin is uneven coating film, adhesion is poor, process fluctuations, quality unstable problems and developing excellent performance, quality and stability of high performance coating grade polypropylene resin has become a polypropylene industry is in urgent need.In this paper, the research directions of high performance coating grade polypropylene resin were developed by chemical degradation method.. In Daqing Petrochemical Company grade T30 S general polypropylene resin as the base resin, adding peroxide as molecular weight regulator, anti oxygen, toughening, and other necessary additives are added, by twin screw extrusion melt blending extrusion granulation. Then, the properties of the experimental raw materials and the production conditions of the experimental raw materials and the screening of many times, determine the high performance coating grade polypropylene resin formulation and production process.In the end, the satisfactory results are obtained in the experimental comparison of the woven bag production device.. The high performance coating grade polypropylene resin has the characteristics of good fluidity, high adhesive strength, uniform film uniformity, strong technology adaptability, etc. all the indexes are better than the existing products..
