Embodiment Construction

[0023] specific implementation plan

[0024] The production process of the present invention is continuously carried out from feeding to the completion of full dynamic vulcanization and pelletizing. The length of time and the size of the output of the material in the reaction process in the equipment of the present invention are mainly realized by controlling the amount of feeding and adjusting the rotating speed of the screw.

[0025] Now illustrate the present invention in conjunction with accompanying drawing of equipment:

[0026] Take the main material EPDM 43%, PP 18.5%, stir in the high-speed mixer (1) for 3 minutes at high speed, add it into the dynamic melt-mixing vulcanization reactor through the main material feeding cylinder (5), and then press paraffin oil 29.5%, paraffin oil + DCP 9% ratio to take the material, respectively add the agitator (9) of the vulcanization aid injection device (3), heat the upper tank (10) to 100 °C through the valv...

Abstract

The invention discloses a dynamic wholly vulcanized thermoplastic rubber one-step production process and apparatus, which comprises EPDM rubber 30-55%, polypropylene (PP) 15-60%, mineral wax oil 6-30%, mineral wax oil + dicumyl peroxide (DCP) 3-15%, and the preparation process comprises high speed agitating, dynamic melting reacting, and pelleting into granular form rubber product.

Description

technical field [0001] The invention discloses a one-step dynamic fully vulcanized thermoplastic rubber production process and equipment, which belongs to the field of polymer materials, and in particular relates to novel thermoplastic elastomer materials. Background technique [0002] Rubber school materials are important polymer materials, which are widely used in various fields of national economy and science and technology. Rubber needs to be vulcanized to be practical, and the traditional rubber vulcanization process is a thermosetting material processing, and its processing technology is complicated, labor-intensive and pollutes the environment. Therefore, dynamic fully vulcanized thermoplastic rubber has attracted great interest, because this material combines the elastic properties of rubber with the easy processing and molding properties of thermoplastic materials. [0003] At present, there are a few units in China that are involved in the ...
