Thermoplastic elastomer oil filled device

Abstract

The invention discloses a thermoplastic elastomer oil filled device, and belongs to the technical field of thermoplastic elastomers. The oil filled device comprises an oil pump, a constant-temperatureoil storage tank, a high-accuracy plunger pump, a loss-in-weight feeding device, a high-speed mixer, a cold mixing dispersion kettle and a control unit. The oil pump is connected with a large oil storage tank through a pipeline, the constant-temperature oil storage tank is connected with the oil pump through a pipeline and connected with the high-accuracy plunger pump through a pipeline, the high-accuracy plunger pump is connected with the high-speed mixer through a pipeline, the loss-in-weight feeding device is arranged above the high-speed mixer, the high-speed mixer is connected with the cold mixing dispersion kettle through a pipeline, a discharging port is formed in the cold mixing dispersion kettle, the oil pump, the constant-temperature oil storage tank, the high-accuracy plunger pump, the loss-in-weight feeding device, the high-speed mixer, the cold mixing dispersion kettle are electrically connected with the control unit, the control unit is used for controlling turning on orturning off of components. The oil filled device has the advantages that matched materials are accurately weighed, thermoplastic elastomers and mineral oil are more sufficiently mixed, and oil is more uniformly filled and the like.

Description

technical field [0001] The invention belongs to the technical field of thermoplastic elastomers, and in particular relates to a thermoplastic elastomer oil-filling device and method. Background technique [0002] Thermoplastic elastomer (TPE) is a kind of synthetic rubber, which has the high elasticity of traditional cross-linked vulcanized rubber, and at the same time has the characteristics of convenient processing and wide processing methods of ordinary plastics. There are many types of thermoplastic elastomers, and many of them need to be filled with mineral oil during processing to obtain better processing performance or other properties. For example, styrenic elastomers, including styrene-butadiene-styrene block copolymer (SBS), hydrogenated styrene-butadiene-styrene block copolymer (SEBS), styrene-isoprene Styrene-Styrene (SIS), Hydrogenated Styrene-Isoprene-Styrene (SEPS), etc. Most grades need to be filled with mineral oil when processing. At present, TPE is basic...

AI Technical Summary

Problems solved by technology

(1) Manual operation is easy to make mistakes; due to the relatively poor production environment of plastic and rubber, with the improvement of people's health awareness, these positions have problems such as difficulty in recruiting people and rapid loss of personnel, and the rapid flow of personnel will inevitably increase Reduced chance of compounding errors

(2) The accuracy of the ingredients is poor; mineral oil is easy to stick to the wall and splash, and it is difficult to ensure the consistency of the mineral oil in the weighing container every time. Affect the accuracy of weighing

(3) The uniformity of the product is poor; the weight of each weighing is different, and at the same time, the oil is directly poured on the TPE, so that a part of the TPE contacts the oil earlier, so that the oil absorption is relatively large, while the other part will have a relatively small oil absorption. , it is difficult to achieve better homogenization

(4) There is a high risk of workers being injured; mineral oil is spilled on the ground and the ground is slippery, which can easily cause workers to slip
