Problems solved by technology

However, reclaimed rubber manufacturers in my country generally use ordinary rubber materials for mixed use, so that the product quality cannot be improved.
Due to the use of coal tar as a softener in the production process of reclaimed rubber, there is a strong stench in the production site, which has great pollution to the environment

Embodiment 1

[0017] A kind of rubber regeneration method of the present invention, comprises the following steps: first select waste and old rubber, carry out the steps of cleaning, drying, cutting, crushing successively, the steps of cleaning, drying, cutting, crushing are carried out at normal temperature, and the finely crushed rubber Fineness to 40 mesh, then put the crushed rubber in the reactor and add desulfurizer, stir evenly to make the reaction fully, add softener in the reactor, the softener is fatty acid, the initial temperature in the reactor is 250°C , the heating rate is 80°C / h, and then the rubber is cooled in a cooling tower. The cooled rubber is pressed out by the refiner and open mill in the rubber pressing equipment to make recycled rubber products without damaging the rubber. Linear molecular chain, safe material extraction and operation, environmental protection, odorless, save oil resources, improve rubber quality, no environmental pollution, reduce the requirements f...

Embodiment 2

[0019] A kind of rubber regeneration method of the present invention, comprises the following steps: first select waste and old rubber, carry out the steps of cleaning, drying, cutting, crushing successively, the steps of cleaning, drying, cutting, crushing are carried out at normal temperature, and the finely crushed rubber Fineness to 35 mesh, then put the crushed rubber in the reactor and add desulfurizer, stir evenly to make the reaction fully, add softener in the reactor, the softener is fatty acid, the initial temperature in the reactor is 300°C , the heating rate is 60°C / h, and then the rubber is cooled in a cooling tower.

Abstract

The invention discloses a rubber regeneration method. The rubber regeneration method comprises the following steps: firstly selecting waste rubber, and carrying out the steps of washing, drying, slicing and smashing in sequence; then putting the smashed rubber in a reaction kettle, adding a desulfurizing agent, uniformly stirring so as to react completely; then putting and cooling the rubber in a cooling tower; pressing and tabletting the cooled rubber through a refining mill and an open mill in rubber pressing equipment, thus preparing a regenerated rubber finished product. Compared with the prior art, the rubber regeneration method disclosed by the invention has the following advantages that a linear molecular chain of the rubber cannot be damaged, material taking and operation are both safe, environment protection is realized, no smell exists, the petroleum resource is saved, the rubber quality is increased, the environment is not polluted, equipment requirements on production are reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to a rubber regeneration method. Background technique [0002] Due to the shortage of international oil resources, the prices of various types of rubber are constantly rising. Therefore, rational use of renewable resources and reduction of production costs will be an inevitable choice. In the next few years, the shortage of rubber resources will continue to trouble countries all over the world. my country has also formulated a strategy for the development of circular economy, so the reuse of rubber resources is becoming more and more important. [0003] With the development of modern society, the consumption of rubber is increasing, and the production of waste rubber is also increasing. However, waste rubber must be regenerated before it can be reused. Regeneration makes waste rubber into treasure and improves its use value. . With the continuous improvement of international environmental protection awareness, it has been announ...
