Embodiment 1

[0047] see Figure 1-3 , a method for continuously processing plastic masterbatches, comprising the following steps:

[0048] S1. Weigh a certain mass ratio of epoxy resin, bentonite, dispersant, compatibilizer, antibacterial agent, binder, film-forming agent, and plasticizer to obtain a mixture by melting and blending, and import the mixture into a twin-screw extruder extrusion molding;

[0049] S2. The masterbatch formed in S1 is automatically screened by the vibrating screen according to the size of the masterbatch, and the mixing and heat removal device is installed in the dehumidification cylinder 1 with the head 2 installed. The mixing and heat removal device is installed at the bottom of the head 2. At the end, the first motor that drives the mixing and heat removal device is installed on the head 2;

[0050] S3. Introduce the masterbatch into the dehumidification cylinder 1, rotate the moisture-absorbing column on the mixing and heat-dispelling device, and use the fi...

Abstract

The invention discloses a plastic master-batch continuous processing method, belonging to the technical field of plastic master-batch processing. According to the plastic master-batch continuous processing method, a mixing and stirring heat dissipation device with a moisture absorption column is arranged in a dehumidification cylinder, and after screened master-batch to be dried is put into the dehumidification cylinder, the master-batch in the dehumidification cylinder is stirred by the mixing and stirring heat dissipation device; heat is transferred to the master-batch in the stirring process, so that uniform heating of the master-batch is achieved; the moisture absorption column can complete alternate operation of moisture absorption and drying in the moisture absorption process, and when the moisture absorption column absorbs water to reach a certain saturation state, the moisture absorption column can effectively realize the cyclic and repeated absorption of water through the heating and drying treatment of the mixing and stirring heat dissipation device without the requirement of selecting by technicians; and therefore, the situation that the dehumidification and drying performance is poor along with prolonging of the use time and increase of absorbed water is avoided, continuous heat transfer and dehumidification integrated continuous operation can be achieved, and the drying efficiency in the plastic master-batch processing process is improved.

Description

technical field [0001] The invention relates to the technical field of processing plastic master batches, and more specifically, relates to a continuous processing method for plastic master batches. Background technique [0002] Plastic masterbatches are used as semi-finished raw materials for processing plastic products. Plastic masterbatch contains plastic auxiliary agent, when making plastic products, just choose the corresponding masterbatch directly. The plastic masterbatch can simplify the processing technology of plastic products, facilitate automatic production and improve labor efficiency. [0003] Many plastic particle raw materials must be dehumidified and dried to a certain extent before they can be used to ensure the transparency and smoothness of plastic products. The existing plastic masterbatch drying processing equipment has a slow drying process, requires a long production line, and occupies a lot of space; [0004] In addition, the existing drying equip...
