Melting and mixing device for producing polymer blend

Abstract

The invention discloses a melting and mixing device for producing a polymer blend. The melting and mixing device comprises a device body and is characterized in that a melting barrel is mounted at the top in the device body; a heating chassis is arranged at the bottom of the melting barrel; the heating chassis is placed in a heat conduction layer; a heater is arranged below the heat conduction layer; the heater and the heat conduction layer are connected through heat conduction bars; and a temperature sensor is arranged in the heat conduction layer. According to the melting and mixing device for producing the polymer blend, the melting barrel is heated by arranging the heater and the heat conduction layer, so that it can be ensured that the heating chassis can be uniformly heated, the molecular structure of a high-molecular compound is prevented from being damaged by too high local heating, and meanwhile, mixing of different high-molecular compound liquids is facilitated; and a first stirring box and a second stirring box are arranged, so that it is ensured that the high-molecular compound liquids are fully stirred and mixed, and the quality of the blend is ensured.

Description

technical field [0001] The invention relates to the technical field of polymer production equipment, in particular to a melting and mixing device for producing polymer blends. Background technique [0002] Polymer blends are used in a wide variety of applications. For example, replacing metal parts with parts made of plastic materials (polymer compositions) results in parts with lighter weight and similar or improved performance characteristics. In many applications, such as those used in automotive underhood parts, plastic materials with high heat resistance are required. However, in general, plastic materials having high heat resistance are difficult to mold. Blending polymers is a way to obtain plastic materials with a desired set of physical properties such as high heat resistance and processing properties. During the production of polymer blends, it is necessary to combine several polymers Compounds are melted and then stirred and mixed. However, the existing melting...

However, in general, plastic materials with high heat resistance are difficult to mold

Blending polymers is a way to obtain plastic materials with a desired set of physical properties such as high heat resistance and processing properties. During the production of polymer blends, it is necessary to combine several polymers Compounds are melted and then stirred and mixed. However, the existing melting and mixing devices have uneven heating during the heating and fusion of polymer compounds, and various polymer compound solutions are not stirred uniformly and cannot always ensure the mixing of polymer compounds. The solution always maintains a high and constant temperature, which leads to a decrease in the activity of the mixed solution, which has a great impact on the quality of the polymer blend; at the same time, the existing equipment has a lot of energy loss during the heating and heat preservation process, and the heat energy cannot be recycled. cause waste of resources
