Problems solved by technology

[0002] At present, plastics have been widely used in the fields of construction, packaging materials, household daily necessities, and automobiles; due to different working environments, there are high requirements for the comprehensive mechanical properties of plastic parts; when making plastics, the raw materials are passed through a mixer The mixing obtained after mixing needs to be cooled and then pelletized to obtain plastic products; in the existing cooling technology, most of the cooling technology uses the mixing directly to the static water for cooling; but this method will make the water temperature uneven, The cooling effect is reduced; at the same time, the impurities brought during cooling will be pelletized together, which affects the quality of the product

Abstract

The invention discloses a process for processing a stress-resistant plastic part, which comprises the following steps: a. mixing: mixing ethylene hexene copolymerized polyethylene resin, antioxidant, auxiliary antioxidant and mold release agent; b. mixing: The mixture in a is kneaded; c, cooling: the extruded mixture in b is cooled; d, pelletizing: the mixture in c is pelletized; the cooling tank in c includes a main body, a Material port, cooling chamber, transfer roller, transfer spring, guide cylinder, guide device, drying chamber, fan, drying device, rotating wheel, first collection belt, collection spring, second collection belt, second motor, Drive cylinder, scraper, opening and water removal mechanism; the preparation of this method of the present invention can improve the stress resistance of plastics and make the comprehensive mechanical properties of plastics higher; drying the cooled mixture can remove the flushing in the cooling water. Therefore, the quality of the plastic is improved; the impurities in the drying cavity are automatically cleaned at the same time, and the efficiency of cooling and drying is improved.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, in particular to a processing technology for stress-resistant plastic parts. Background technique [0002] At present, plastics have been widely used in the fields of construction, packaging materials, household daily necessities and automobiles; due to different working environments, there are high requirements for the comprehensive mechanical properties of plastic parts; when making plastics, the raw materials are passed through the mixer. The kneading obtained after kneading needs to be cooled and then cut into pellets to obtain finished plastic products; in the existing cooling technology, most of the mixing materials are directly led to static water for cooling; but this method will make the water temperature uneven, As a result, the cooling effect is reduced; at the same time, the impurities brought by the cooling will be diced together, which will affect the quality of the produ...
