Waste rubber regenerated rubber compound production system

Abstract

The invention discloses a waste rubber regenerated rubber compound production system. The production system consists of three parts of a rubber powder single spiral plasticizing device, a multi-feed-port multi-section double-screw extruder and a pelletizing and packing device; the multi-feed-port multi-section double-screw extruder comprises a multi-feed-port multi-section double-screw main body part and a cooling extrusion device, wherein a first discharge port of the rubber powder single spiral plasticizing device is connected with a second feed port of the multi-feed-port multi-section double-screw extruder through a connecting valve; and the pelletizing and packing device is mounted at the tail end part of the multi-feed-port multi-section double-screw extruder. The production system realizes continuous production of per-desulfurized rubber particles obtained by rubber particle microwave heating / double-screw shearing, semi-desulfurized rubber powder obtained by rubber powder electromagnetic heating / single-spiral plasticizing and waste rubber regenerated rubber compound obtained by rubber powder mixing; products are green, environment-friendly and excellent in performances, and the performances can be adjusted according to actual demands; and the products can be widely applied to such fields as such rubber products as tires and rubber plates, waterproof coiled materials and road asphalt.

Description

Technical field: [0001] The invention relates to the field of reclaimed rubber production, and mainly relates to a waste rubber regenerated mixed rubber production system. Background technique: [0002] With the rapid development of the rubber industry, the accumulation of a large amount of waste rubber is difficult to decompose, causing various environmental problems and forming "black pollution". However, my country's natural rubber and petroleum resources are seriously lacking, and most of them rely on imports. Therefore, how to deal with them more effectively It is imminent to turn waste into high-value utilization. [0003] The methods of producing recycled rubber from waste rubber in my country have experienced a series of development processes such as oil method, water-oil method, high-temperature and high-pressure dynamic desulfurization method, and normal-pressure plasticization method. The common points are not to get rid of the chemical desulfurization method from ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a waste rubber regenerated mixed rubber production system to solve the problem of difficulty in controlling the physical and mechanical shear regeneration of waste rubber in the prior art to achieve maximum destruction of sulfur-containing bonds while maintaining the carbon-carbon bond main chain The structure is not destroyed to get this defect close to the performance of raw rubber, and realize the continuous production of waste rubber recycled compound rubber
