Description

Technical field: [0001] The invention relates to a continuous production device of thermoplastic polyurethane elastomer, which belongs to the technical field of new materials. Background technique: [0002] Thermoplastic polyurethane elastomer (TPU) is a kind of elastomer that can be plasticized by heating and can be dissolved by solvent. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance. It has good processing performance and is widely used in national defense, medical treatment, Food and other industries. Thermoplastic polyurethane elastomer, with its excellent performance and wide application, has become one of the important thermoplastic elastomer materials, which has many excellent properties, such as high modulus, high strength, excellent wear resistance, chemical resistance , Hydrolysis resistance, high and low temperature resistance and mold resistance. These good properties make thermoplastic polyu...

Problems solved by technology

[0003] The existing production process of thermoplastic polyurethane elastomers generally uses reactors to react, then send them to vacuum baking, and then slice them after drying. There are many links in the production process that require manual participation, especially in the vacuum baking stage. The material in the device is directly sent to the drying box through the pipeline, which is easy to cause material accumulation and must be manually thinned, resulting in low production efficiency
