  随着载体树脂的快速变化,聚烯烃填充色母粒的加工工艺及相关设备也逐渐发生变化。

  With the rapid change of carrier resin, the processing technology and related equipment of polyolefin filling masterbatch have changed gradually.
  第一代聚烯烃填充色母粒(APP色母粒)使用的载体树脂是国内随机聚丙烯(实际上是聚丙烯生产的副产品)。其工艺流程为:搅拌—锻拉板—水冷造粒。由于是间歇生产,所使用的设备包括混合器、混合器和制版造粒机。
  The carrier resin used in the first generation of polyolefin filler masterbatch (APP masterbatch) is random polypropylene (in fact, by-product of polypropylene production) in China. The technological process is stirring, forging and drawing plate and water-cooled granulation. Because of intermittent production, the equipment used includes mixer, mixer and plate granulator.
  第二代聚烯烃填充色母粒是以LDPE (1F7B)为载体树脂,生产的色母粒称为PEP色母粒。该工艺必须采用长径比大、混合性能好的单螺杆挤出机,才能获得较好的效果。
  The second generation of polyolefin filling masterbatch is based on LDPE (1F7B) as carrier resin. The Color Masterbatch produced is called PEP masterbatch. The process must adopt a single screw extruder with large aspect ratio and good mixing performance in order to achieve better results.
  这种以聚丙烯粉末为载体的填充母材,即PPM母材,被称为我国第三代填充母材。一般采用聚丙烯和聚乙烯共混物制成载体树脂的方法,效果会很好。该产品既保持了PPM母材的特性和适用范围,又采用了模具表面热风冷却工艺,提高了生产效率,降低了原材料成本。

  This kind of filling base material, PPM base material, which takes polypropylene powder as carrier, is called the third generation filling base material in China. In general, the method of making carrier resin from polypropylene and polyethylene blends has a good effect. The product not only maintains the characteristics and application scope of PPM base material, but also adopts hot air cooling technology on the surface of the mould, which improves the production efficiency and reduces the cost of raw materials.
  制造填料的最佳加工设备是同转双螺杆挤出机。该机具有生产连续、质量稳定、生产效率高、能耗低、劳动强度低、运行环境好等优点。
  The best processing equipment for filling is rotary twin screw extruder. The machine has the advantages of continuous production, stable quality, high production efficiency, low energy consumption, low labor intensity and good operating environment.
  填充物材料中填充物和助剂的浓度较大,必须向填充物中加入一定量的基体树脂,搅拌后再进行加工成型。填料主要起填充作用。填料和添加剂可以赋予塑料制品特殊的功能,如:光、电、阻燃、降解等,被称为功能填料的母体材料。功能母料一般包括色彩母料、光转换母料、高效保温膜母料、防雾滴母料和降解母料。
  The concentration of fillers and additives in filler materials is relatively high. A certain amount of matrix resin must be added to the filler, and then processed after stirring. Packing mainly plays a filling role. Fillers and additives can give plastic products special functions, such as light, electricity, flame retardant, degradation and so on. They are called matrix materials of functional fillers. Functional masterbatches generally include color masterbatches, light conversion masterbatches, high efficiency thermal insulation film masterbatches, anti-fogging masterbatches and degradable masterbatches.
  色母粒是用于塑料制品着色的特殊颗粒。它可分为聚烯烃型、ABS型、PS型和AS型。
  Colour masterbatch is a special granule used for colouring plastic products. It can be divided into polyolefin type, ABS type, PS type and AS type.
  母料灌装的生产过程一般分为两个步骤:
  The production process of master batch filling is generally divided into two steps:
  其中一步是制备颜料预分散剂,是使用分散剂或其他添加剂对颜料进行表面处理;第二步是将颜料预分散树脂与载体树脂混合造粒制备母粒。母料是由颜料,分散剂,载体树脂和适量的添加剂改性。分散剂的主要作用是使颜料充分分散,均匀地分散在载体树脂和基体树脂中,最终得到颜色均匀的塑料制品。母粒中使用的载体树脂应与包覆树脂具有良好的相容性,第二载体树脂应比包覆树脂具有更大的流动性,以使颜料的分散效果越来越好。色母的组成,颜料的选择和颜料的数量取决于被着色塑料的性质。
  One step is to prepare pigment pre-dispersant, which is to use dispersant or other additives to treat the surface of the pigment; the second step is to prepare masterbatch by mixing the pigment pre-dispersing resin with the carrier resin. The masterbatch is modified by pigments, dispersants, carrier resins and appropriate additives. The main function of dispersant is to make the pigments fully dispersed, evenly dispersed in the carrier resin and matrix resin, and eventually get the plastic products with uniform color. The carrier resin used in Masterbatch should have good compatibility with the coated resin. The second carrier resin should have greater fluidity than the coated resin so as to make the dispersing effect of the pigment better and better. The composition of masterbatch, the selection of pigments and the number of pigments depend on the properties of the pigmented plastics.
