Description

Technical Field

[0001] The utility model relates to the technical field of stirring, in particular to stirring equipment for processing modified polypropylene. Background Art

[0002] Polypropylene is a general-purpose plastic resin with a wide source and low price, and has a very wide range of uses. However, due to its high brittleness (especially low-temperature brittleness), high crystallinity, and low molecular polarity, PP has poor miscibility and adhesion with other polymers (such as plastics, rubbers) and inorganic fillers, which limits its application in some fields. Therefore, unmodified polypropylene (PP) is limited in many aspects due to its insufficient strength and toughness. It is modified by adding a mixing agent. There are two main methods for modifying PP: physical modification and chemical modification. Physical modification is to add various fillers or additives to PP as a matrix.

[0003] In order to solve the problem that sedimentation and accumulation are easy to occur at the bottom of the mixing barrel, resulting in uneven mixing of the raw materials of modified polypropylene, the prior art adopts a stirring mechanism to be arranged on the mixing barrel. The stirring mechanism uses a stirring shaft, a spiral impeller, an L-shaped stirring bracket, a driving motor and a feeding wing to repeatedly lift and stir the raw materials in the mixing barrel, thereby avoiding the accumulation of the raw materials at the bottom of the mixing barrel and preventing stratification, thereby making the raw materials mixed more evenly. This method has a simple structure, but the cleaning work of the device is more troublesome, which leads to the problem of increased manual labor. Therefore, it is necessary to design and transform the stirring equipment for modified polypropylene processing to effectively prevent the inconvenience of cleaning. Utility Model Content
