Problems solved by technology

However, high-strength (GB 08 tearing strength above 12MPa) reclaimed rubber must be made of tire roof (GB 08TA1) rubber powder with high rubber hydrocarbon content, which is greatly restricted by high cost, large market demand, and poor collection of material sources.
Full tire rubber powder can only be used as ordinary reclaimed rubber (GB 08 tear strength below 12MPa), and cannot be used to manufacture high-strength reclaimed rubber products

Embodiment Construction

[0014] The invention relates to a method for producing high-strength reclaimed rubber from whole tire rubber powder by oligopolyester, and the process flow is as follows:

[0015] Raw material screening→homogeneous mixing of oligomeric fat and regeneration activator→uniform mixing of oil and rubber powder→desulfurization of mixed powder→refining→pulling out→weighing and packaging.

[0016] in,

[0017] (1) The homogeneous mixing of oligopolyester and regeneration activator, and the uniform mixing of oil and rubber powder are completed in the mixing tank at a temperature of 60°C to 120°C after 180 seconds to 300 seconds of stirring.

[0018] (2) Desulfurization of the mixed powder: step 1, carry out the desulfurization equipment in the desulfurization tank at 160 ℃ ~ 220 ℃, steam pressure 1.5MPa ~ 2.2MPa under high temperature and high pressure for 2 to 6 hours; step 2, in the screw extrusion desulfurization equipment Carry out at 240°C-320°C under high temperature and normal ...

Abstract

The invention relates to a method for manufacturing full-tire rubber powder high-tenacity reclaimed rubber by oligomer ester. The method includes the steps: matching the oligomer ester into a regeneration activator system; uniformly stirring and mixing the oligomer ester and full-tire rubber powder in a high-temperature mixing tank to obtain mixed rubber powder; recovering the mixed rubber powderby the aid of waste rubber desulphurization devices (dynamic desulphurization tank device, screw extrusion device and spiral extrusion device) to form disulfide powder; refining and packaging the disulfide powder to form high-performance reclaimed rubber products. The method solves the problem of high consumption of domestic high-tenacity reclaimed rubber.

Description

technical field [0001] The invention relates to a method for preparing full-tire rubber powder high-strength reclaimed rubber from oligomer. The invention belongs to the technical field of recycled rubber. Background technique [0002] At present, the manufacture of reclaimed rubber industry adopts the combination of rubber powder and regeneration activator, and then goes through desulfurization and refining processes. However, high-strength (GB 08 tear strength above 12MPa) reclaimed rubber must be made of tire roof (GB 08TA1) rubber powder with high rubber hydrocarbon content, which is greatly restricted by high cost, large market demand, and poor collection of material sources. Full-tire rubber powder can only be used as ordinary reclaimed rubber (GB 08 tear strength below 12MPa), and cannot be used to manufacture high-strength reclaimed rubber products. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned disadvan...
