Example Embodiment

[0024] Example 1

[0025] Add 50 kilograms of 20-40 mesh waste tire rubber powder to a 200-liter high-speed mixer, add 250 grams of composite environmentally friendly regeneration activator, 250 grams of Pitong-22, 5 kilograms of stearic acid, 100 grams of accelerator D, 100 grams A mixture of antioxidant BHT, 100 g of manganese dioxide, 6 kg of environmentally friendly aromatic oil, processing aid is a mixture of 250 g of rosin, 5 kg of light calcium carbonate, mixed in a high-speed mixer for 8-12 minutes, then mixed at high speed The material in the machine is heated to 120°C due to friction, and the material can be discharged. Put the initial mixture made by mixing into an open mill or extruder, and after 5-8 minutes of compression, it will become a uniform sheet and ready-to-use recycled rubber.

[0026] According to the national standard GB / T13460-2008, the performance of the recycled rubber was tested and the basic performance of the recycled rubber in this example was in li...

[0028] Example 2

[0029] Add 50 kilograms of 20-40 mesh waste tire rubber powder into a 200-liter high-speed mixer, and add 250 grams of Pitong-22, 5 kilograms of stearic acid, 100 grams of urea, and 100 grams of antioxidants. A mixture of BHT, 100 g of manganese dioxide, 6 kg of vegetable pitch, and a processing aid of 250 g of coumarone resin, 4 kg of light calcium carbonate, and 1 kg of white carbon black. Stir in a high-speed mixer for 8- After 12 minutes, the material in the high-speed mixer is heated to 120°C due to friction, and the material can be discharged. Put the initial mixture made by mixing into an open mill or extruder, and after 5-8 minutes of compression, it will become a uniform sheet and ready-to-use recycled rubber.

[0030] According to the national standard GB / T13460-2008, the performance of recycled rubber was tested and the basic performance of the recycled rubber in this example was in line with the national recycled rubber A2 standard.

Abstract

The invention discloses a reclaiming agent, reclaimed rubber prepared therefrom, and a preparation method of the claimed rubber. The reclaiming agent comprises the following components in parts by mass: 0.5-3 parts of regenerated activator, 5-20 parts of regenerated swelling agent and 1-10 parts of other processing aids. The reclaiming agent, the reclaimed rubber and the preparation method of the claimed rubber have the beneficial effects that crumb rubber powder, used environment-friendly regenerated activator and the swelling agent are uniformly mixed and then added to rubber mixing equipments, such as an open mill and an extruder to reclaim under the condition from room temperature to 50 DEG C in a high-speed mixer in the process of preparing the environment-friendly reclaimed rubber; the regenerating temperature is low, so that bad objectionable odor and staining property of the traditional reclaimed rubber are removed. Compared with the traditional reclaimed rubber, the environment-friendly reclaimed rubber has the advantages that the mechanical property and the processing property are not reduced by a test; chemicals which are not permitted to use are not contained in 'REACH'; the reclaiming agent is simple and efficient in processing technology, and fewer in regenerating procedure; various rubber mixing equipments can carry out regeneration operation.

Description

technical field [0001] The invention belongs to the recycling field of waste rubber, and relates to a regenerant, regenerated rubber prepared by using the regenerant and a preparation method. Background technique [0002] The chemical reaction between the rubber macromolecular chain and the vulcanizing agent such as sulfur, accelerator, etc. makes the chemical cross-linking points between the rubber macromolecular chains change from a linear one-dimensional structure to a three-dimensional space network structure, improving the physical and mechanical properties of the rubber, but cross-linking The combined rubber cannot be naturally degraded for a long time after being discarded, and most of it becomes industrial waste. In the case of high prices, shortage of resources and accelerated deterioration of the environment, it is of great significance to reduce the environmental burden, efficiently recycle waste rubber resources, and realize the green cycle of basic raw material ...
