Problems solved by technology

In the regeneration process, due to the addition of a large amount of softener pine tar, coal tar, petroleum extract, etc., the recycled materials discharged from the high-temperature regeneration tank to the open mill have uneven texture and uneven material distribution, which requires refining, but the discharged recycled rubber Very sticky roller

Embodiment Construction

[0015] Further illustrate the scheme and effect of the present invention below in conjunction with embodiment.

[0016] Adjust the roller distance to 0.5mm, discharge 0.5kg of recycled materials discharged from the internal mixer (model XSM-1 / 20~80) above the roller of the XK-160 open mill, through the huge extrusion force of the roller and The shear force disperses the material, and the rubber material is immediately wrapped around the roll. Because the roll distance is too small, the large agglomerates formed during the regeneration process cannot enter the roll gap and just roll on the roll. Therefore, when the mill is turned on, the roll distance is gradually increased from 0.5mm to 3.0mm, so that all the materials flow into the roll gap to disperse the extrusion force and shear force of the material, and the rubber material passes through the roll 10 times. . Stop the open mill, cut the rubber material wrapped on the roller with a rubber tapping knife, start the ope...

Abstract

The invention discloses a refining method for an adhesive-roll open mill for high-temperature reclaimed rubber, which belongs to the technical field of waste rubber. The method includes the steps: discharging reclaimed material to the open mill, gradually increasing roll spacing to allow the rolls to be wrapped with the reclaimed material; cutting and removing roller wrapping rubber, thinning the rubber and refining; coating soap liquid and cooling; visually observing qualification of surface properties; and obtaining finished reclaimed rubber. The method has the advantages that the regeneration process is simplified when no rubber scraper is mounted on an open mill in research institutions and laboratories, refining devices are reduced, the reclaimed rubber is guaranteed has even color and smooth surface, the quality of the reclaimed rubber is guaranteed, normal development of experimental reaches and production is guaranteed, and refining is achieved.

Description

technical field [0001] The invention relates to the technical field of waste rubber regeneration, in particular to an open mill refining method for high-temperature regenerated rubber with sticky rollers. This method is suitable for the refining of high-temperature anhydrous and easy-sticking roller reclaimed rubber that is not equipped with a rubber scraper on the open mill. It is mainly used for small-scale open mills in the laboratory when there is less rubber material, and there is no scraper. The device can also ensure the smooth progress of the refining and mixing process. Background technique [0002] The amount of waste rubber materials is second only to waste plastics among waste and old polymer materials. Among them, the annual scrap volume of automobile tires in the world is more than 1 billion, and that in my country is 50-60 million. The recycling of waste rubber is mainly waste tires, and others include waste rubber shoes and inner tubes, etc. The utilization ...
