Embodiment Construction

[0005] Use a mechanical shredder to crush waste car tires to below 40 mesh, then separate the chemical fiber and steel wire segments in the tire, put the crushed rubber particles into a stainless steel cylinder, stir with a grease decomposer, dynamically desulfurize, and pressurize to 15—— 18 kg, heated to 200-240°C, and then placed for 3 hours, the exhaust gas in the cylinder is neutralized by acid and alkali, and then discharged to the atmosphere after meeting the environmental protection requirements, and the waste water in it is recycled into the stainless steel cylinder for reuse, mechanically desulfurized, and pressed into tablets Tablet forming by machine, leaving the factory after inspection.

[0006] The regenerated rubber produced has no odor, and its physical and chemical performance indicators also meet the requirements. It can replace natural rubber in many products. It is a very popular waste rubber regeneration treatment method. At the same time, the discharged ...

Abstract

The invention relates to a method to obtain regeneration rubber without odor by processing waste tyre with decomposition, which comprises following steps: (1) smashing material less than 40 items; (2) separating chemical fiber and steel wire; (3) putting smashed rubber particle into canister; (4) mixing with oil splitter; (5) dynamic desulfurizing for three hours on pressure of 15-18kg and 200-240Deg; (6) neutralizing waste gas to release, recycling waste water into canister; (7) mechanical desulfurizing; (8) mechanical tabletting. This invention has no pollution to environment and can recycle rubber.

Description

technical field [0001] The invention relates to a method for treating waste tires to obtain odorless regenerated rubber by a decomposition method. Background technique [0002] At present, in order to make full use of waste rubber, there are many ways to deal with the regeneration of waste rubber, but ordinary regenerated rubber is usually processed mechanically and chemically under heat and pressure conditions to make the vulcanized rubber reticular. The cross-linked structure is degraded and has plasticity, and becomes regenerated rubber for re-vulcanization processing. However, in the production process, there are high energy consumption and complicated processes. At the same time, a large amount of waste water, waste gas and harmful substances will be generated, which will greatly pollute the environment, especially Reclaimed rubber has a strong odor. Contents of the invention [0003] The purpose of the present invention is to solve the problem of strong odor of rege...
