Classification of filled polypropylene
Filling polypropylene is to mix polypropylene resin with a certain proportion of fillers (such as calcium carbonate, talc, asbestos, mica and wood powder, etc.) and some necessary additives, and then mix and plasticize with an extruder after mixing evenly. , and then extruded and pelletized, the pellets are filled polypropylene.
(1) Performance characteristics The performance of filled polypropylene is related to the content of the filler, the performance of the filler, the type, particle size, shape, and dispersion state and uniformity of the polypropylene resin. The properties of filled polypropylene usually have the characteristics of good heat resistance, low shrinkage rate of molded products, good dimensional stability, and relatively high hardness. If the amount of filler is relatively high, the properties of this filled polypropylene (such as heat resistance, cold resistance, mechanical properties and processability, etc.) are better than those of pure polypropylene resin molded products; but the gloss, Toughness and elongation at break decreased significantly.
The performance comparison between calcium carbonate filled polypropylene and pure polypropylene resin is shown in Table 2-55. The performance comparison of mica, talc and glass fiber filled polypropylene and pure polypropylene is shown in Table 2-56. The properties of filled polypropylene produced by Beijing Yanshan Petrochemical Company, Zhonglan Chenguang Chemical Research Institute and Shandong Daon Chemical Co., Ltd. are shown in Table 2-56~Table 2-59.

2.2.8 Flame retardant polypropylene The preparation method of flame retardant polypropylene is relatively simple.
Anti-aging agent, treatment agent, flame retardant and auxiliary flame retardant are mixed together, stirred and mixed evenly, and then mixed and plasticized by an extruder, extruded and pelletized, that is, a flame retardant polypropylene product. The performance of flame retardant polypropylene is related to the type of flame retardant in the product formula, the small size of the material and the composition of the material in the formula. Flame retardant polypropylene has excellent flame resistance, and can also be UL94V-0 grade; good thermal aging, use in 15 ℃ environment, life expectancy from 700h; processability is similar to polypropylene resin, good melt fluidity, large moldability Thin-walled products; mechanical strength is close to that of polypropylene products.
