Background

TPV, generally referred to as PP/EPDM type dynamic vulcanized elastomer, is a material developed in recent years, and has the structural characteristics of being composed of two phases of plastic and rubber, so that the TPV has the characteristics of the plastic and the rubber to a certain extent, is easy to realize the control of a precise section, can be recycled under certain conditions, and has little environmental pollution, thereby being very concerned by designers of finished vehicles and sealing systems.

The TPV is produced by melt blending PP and EPDM mixture, adding a cross-linking agent for vulcanization, and utilizing the mechanical high shearing force of an internal mixer, a screw machine and the like to fully disperse particles of completely vulcanized EPDM cross-linked rubber in a PP matrix in a micron size (less than 1 micron).

However, the existing TPV production line has the following defects:

1. the automation degree of the existing TPV production line is not enough, the conveying and mixing of the blending raw materials cannot be reasonably, automatically and efficiently carried out, the middle part of the processes still need manual operation, the production efficiency cannot be improved, and the enterprise yield is influenced.

2. The existing talcum powder is usually packaged and divided into big bags and small bags with different specifications, but when the talcum powder in the bags is poured into a talcum powder buffer bin, the pouring difficulty of the big bags of talcum powder is very high due to overlarge weight, and meanwhile, if manual pouring is carried out, a large amount of dust generated in the process can possibly influence the body health of workers, and if a machine is used for pouring, the talcum powder is easily poured out; the sachet of talc can be poured manually, but there is a risk that if the machine suddenly runs during manual pouring.

3. When current blendor should be in the compounding operation when being more to the raw materials kind, can't realize higher compounding efficiency, current compounding process does not heat usually in addition, perhaps only uses external heating, and heating efficiency is low excessively, and the heating homogeneity is also relatively poor, and contains the peroxide volatile substance in the raw materials, and summer and winter's ambient temperature and the heating efficiency difference of blendor can produce the influence to the volatile volume of peroxide, finally leads to the unstability of product quality.

4. The TPV plastic particles need to be cooled after extrusion molding to be processed in the next stage, and when the yield of a factory is high, if the TPV plastic particles are naturally cooled, the TPV plastic particles are easy to accumulate, the next production is difficult to continue, and the efficiency is reduced.
