Preparation process of ABS (Acrylonitrile Butadiene Styrene) modified plastic particles

Abstract

The invention relates to the technical field of plastic preparation, in particular to a preparation process of ABS (acrylonitrile Butadiene Styrene) modified plastic particles. The preparation process comprises the following steps that step 1, plastic molding and extrusion is conducted, wherein raw materials for preparing the ABS modified plastic particles are added into a plastic preparation device, melting and extruding are conducted along with the raw materials, extruded plastic is strip-shaped, and primary molding of the plastic is completed; and step 2, cooling of extruded plastic strips is conducted, specifically, the extruded plastic strips pass through the interior of the plastic preparation device, cooling water is arranged in the plastic preparation device, and the extruded plastic strips are cooled and shaped in time. According to the device, through the arrangement of a variable-speed traction device, the device can be matched with the extrusion speed of the plastic strips to change the speed, so that the traction speed of the plastic strips is matched with the extrusion speed, the situation that the plastic strips are pulled and broken due to the fact that the traction speed is higher than the extrusion speed is avoided, complete preparation of the plastic particles is facilitated, and meanwhile uniform cutting of the plastic particles is facilitated.

Description

technical field [0001] The invention relates to the field of plastic preparation, in particular to a preparation process of ABS modified plastic particles. Background technique [0002] Plastic is an important organic synthetic polymer material with a wide range of applications. BS resin is an acrylonitrile-butadiene-styrene copolymer, referred to as ABS, which is a bulk general-purpose resin. After modification, ABS is an engineering plastic. ABS alloy has a large output, many types, and is widely used. It is the main modification. plastic. [0003] The prior art discloses some invention patents on plastic preparation. The Chinese patent with application number 201620996333.9 discloses a granulator for preparing plastic granules, including a loading platform, a drying device, a water cooling device, a cutting device and a guiding device. The device and the cutting device are arranged on the carrying platform, and the water cooling device is arranged above the drying devic...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, when preparing ABS modified plastic particles, most of them first extrude plastic strips through the extruder, and make the plastic strips pass through the cooling water tank to cool and solidify, and then cut by traction. However, the plastic extruder is extruding The plastic strip may be unstable, which makes the extrusion speed of the plastic strip difficult to be completely uniform, which causes the plastic strip to be pulled during the pulling process. After the plastic is pulled, the plastic strip does not enter the end of the cooling water tank. As a result, the plastic strips are pulled, deformed and broken, resulting in uneven size of the prepared plastic particles
