Processing and forming system for strip-shaped engineering plastic with high toughness

Abstract

The invention provides a processing and forming system for strip-shaped engineering plastic with high toughness, which is applied to the field of workshops. The processing and forming system comprises a rack, a driving module, a feeding hopper, a transmission module, a heating module, a temperature measuring module and a discharging module. The driving module is arranged to drive a screw of the transmission module to rotate, so that plastic raw materials entering from the feeding hopper are driven to flow; a gear box is arranged, so that the flowing speed of the plastic is better controlled; the heating module is arranged to heat the plastic raw materials in a circulating pipe, so that the materials are fully stirred and fused and can be kept in a relative fluid state; and meanwhile, the heating module is provided with three temperature areas which correspond to three fluid states of the engineering plastic, so that the plastic is different in characteristics in different states and fully reacts with additives, and meanwhile, the toughness of the plastic can be greatly improved.

Description

technical field [0001] The invention relates to the field of engineering plastics, in particular to a processing and forming system for strip-shaped engineering plastics with high toughness. Background technique [0002] Engineering plastics generally refer to plastic materials that can withstand mechanical stress as structural materials and can be used in a wide temperature range and in harsh chemical and physical environments. Engineering plastics can be divided into general engineering plastics and special engineering plastics. General-purpose engineering plastics usually refer to five kinds of plastics that have been produced on a large scale and have a wide range of applications, namely polyamide (nylon, PA), polycarbonate (polycarbonate, PC), polyoxymethylene (POM), polyester ( Mainly PBT) and polyphenylene oxide (PPO).

Problems solved by technology

[0003] After a massive search by our team, we learned that the existing methods of preparing engineering plastics mainly include the publication numbers KR101567749B1, KR100920276B1, KR101436052B1 and CN101974222B, but these equipment are often formed by heating and merging various raw materials to form a plastic template. This method often makes the reaction of each mixture incomplete, and the mixed materials after fine-setting are prone to separation, and the uniform proportion of mixing cannot be ensured before molding, so the toughness of the prepared engineering plastics cannot reach the preset value.
