Problems solved by technology

[0004] In order to make up for the deficiencies in the prior art, solve existing polypropylene degradation agents such as 1,3-two (t-butylperoxyisopropyl) benzene is a solid substance, when mixed with polypropylene powder for granulation, due to feeding and Mixing is not easy and uniform, resulting in uneven degradation of polypropylene, resulting in product quality problems, resulting in poor production controllability and poor stability. A production method for functional fiber-grade polypropylene proposed by the present invention

Embodiment approach

[0039] As an embodiment of the present invention, the transmission assembly 75 includes a disk 751; the disk 751 is fixed on the end of the second rotating shaft 73 away from the second bevel gear 72; the disk 751 is close to the edge There is a revolving pin 752 connected to it in rotation; the side wall of the annular brush plate 76 away from the brush 77 is fixedly connected with a moving plate 753 through a connecting column 755; a chute 754 is provided on the moving plate 753; the revolving pin 752 Slidingly connected in the chute 754; during work, when the disc 751 rotates, the movement of the rotating pin 752 in the chute 754 drives the moving plate 753 to move, and the moving plate 753 moves through the connecting column 755 to drive the annular brush plate 76 to move up and down. To clean the powder bonded in the mixing tank 2.

Abstract

The invention relates to the technical field of polypropylene processing, in particular to a functional fiber-grade polypropylene production method which comprises a shell, a stirring cylinder, a feeding port, a discharging port, a supporting column and a stirring mechanism. The supporting column is fixedly connected to the bottom end of the shell. The stirring cylinder is arranged in the shell and is fixedly connected to the inner side wall of the bottom end of the shell; the pair of feeding holes are symmetrically formed in the top end of the shell and are communicated with the stirring cylinder; the stirring mechanism is arranged on the stirring cylinder; the stirring mechanism comprises a motor, a first rotating shaft and a stirring column; the motor is fixedly connected to the top end of the shell; the functional fiber-grade polypropylene production method aims to solve the problems that when an existing polypropylene degradation agent such as 1, 3-bis (t-butyl peroxy isopropyl) benzene is a solid substance and is mixed with polypropylene powder for granulation, due to the fact that feeding and mixing are not easy to be uniform, the degradation degree of polypropylene is not uniform, product quality problems are generated, production controllability is poor, and stability is poor.

Description

technical field [0001] The invention relates to the technical field of polypropylene processing, in particular to a production method of functional fiber grade polypropylene. Background technique [0002] Fiber grade polypropylene is polypropylene suitable for drawing to make fibers. This polypropylene has high fluidity. In order to obtain this polypropylene, there are mainly two conventional methods, one is to reduce the molecular weight by hydrogenation during the reaction process of preparing polypropylene, but the molecular weight of polypropylene obtained by this method is not uniform; the other is Use a degrader. [0003] In the current prior art, existing polypropylene degradation agents such as 1,3-bis(t-butylperoxyisopropyl)benzene are solid substances, and when mixed with polypropylene powder for granulation, due to feeding and mixing, it is not easy to be uniform , resulting in uneven degradation of polypropylene, resulting in product quality problems, resultin...
