Embodiment 1

[0014] Embodiment 1: produce strong reclaimed rubber according to the following steps

[0015] 1. Powder breaking: decompose, coarsely crush, magnetically separate, finely crush, magnetically separate, screen, and magnetically separate the recovered waste tires in order to obtain 10 mesh waste rubber powder;

[0016] 2. Desulfurization: 10-mesh waste rubber powder is fed into the desulfurizer by the feeder, sprayed with pine tar, activator B-480 and rosin into the desulfurizer through the batching machine, stirred and mixed, and desulfurized at 290°C for 80 minutes to obtain plastic Shaped rubber; wherein, the content of each component is: 78.5% waste rubber powder, 20% pine tar, 0.5% activator B-480, 1.0% rosin;

[0017] 3. Refining: The plastic rubber after desulfurization passes through three open-rolling machines and one refining machine in turn to obtain strong reclaimed rubber; the distance between the rollers of the open-rolling machine is set to 1mm, and the roller tem...

[0019] Embodiment 2: produce strong reclaimed rubber according to the following steps

[0020] 1. Powder breaking: The recovered waste tires are decomposed, coarsely crushed, magnetically separated, finely crushed, magnetically separated, screened, and magnetically separated to obtain 20 meshes of waste rubber powder;

[0021] 2. Desulfurization: 20-mesh waste rubber powder is fed into the desulfurizer by the feeder, sprayed with pine tar, activator B-480 and rosin into the desulfurizer through the batching machine, stirred and mixed, and desulfurized at 300°C for 60 minutes to obtain plastic Shaped rubber; wherein, the content of each component is: 84.05% waste rubber powder, 15% pine tar, 0.35% activator B-480, 0.6% rosin;

[0022] 3. Refining: The plastic rubber after desulfurization passes through three open-rolling machines and one refining machine in turn to obtain strong reclaimed rubber; the distance between the rollers of the open-rolling machine is set to 1mm, and th...

Embodiment 3

[0024] Embodiment 3: produce strong reclaimed rubber according to the following steps

[0025] 1. Powder breaking: the recycled waste tires are decomposed, coarsely crushed, magnetically separated, finely crushed, magnetically separated, screened, and magnetically separated to obtain 30 mesh waste rubber powder;

[0026] 2. Desulfurization: 30-mesh waste rubber powder is fed into the desulfurizer by the feeder, sprayed into the desulfurizer with pine tar, activator B-480 and rosin through the batching machine, stirred and mixed, and desulfurized at 310°C for 40 minutes to obtain plastic Shaped rubber; wherein, the content of each component is: 89.6% waste rubber powder, 10% pine tar, 0.2% activator B-480, 0.2% rosin;

[0027] 3. Refining: The plastic rubber after desulfurization passes through three open-rolling machines and one refining machine in turn to obtain strong reclaimed rubber; the distance between the rollers of the open-rolling machine is set to 1mm, and the roller...

Abstract

The invention discloses reclaimed superglue and a production method thereof. The reclaimed superglue comprises the following components: 78.5-89.6 percent of waste rubber powder, 10-20 percent of pine tar, 0.2-0.5 percent of activating agent B-480 and 0.2-1.0 percent of rosin. The production method comprises the following steps of: carrying out disassembly, coarse crushing, magnetic separation, fine crushing, magnetic separation, screening and magnetic separation on waste tyres in sequence to obtain 10-30 meshes waste rubber powder; feeding the 10-30 meshes waste powder rubber into a desulfurization machine by using a feeder, spraying the pine tar, the activating agent B-480 and the rosin into the desulfurization machine by a dosing machine, stirring and mixing, and desulfurizing for 40-80min at 290-310 DEG C to obtain plastic glue; processing the plastic glue by using three open mills and a refining mill in sequence to obtain the reclaimed superglue, wherein the roller distance of each open mill is set to be 1mm, the roller temperature of each open mill is controlled to be below 70 DEG C, the roller distance of the refining mill is controlled to be 0.2mm-0.4mm, the roller temperature of the refining mill is controlled to be below 90 DEG C; and then shearing the reclaimed superglue into glue blocks each of which is 20KG in weight, metering and packaging the glue blocks and warehousing the packaged glue blocks. The production method disclosed by the invention is continuous and automatic, low in energy consumption, free of water pollution and excellent in performance.

Description

technical field [0001] The invention relates to reclaimed rubber and a production method thereof, in particular to a strong reclaimed rubber and a production method thereof. Background technique [0002] As we all know, reclaimed rubber is generally extracted from waste tires. At present, the dynamic desulfurization method is mainly used to produce regenerated rubber, which has the problems of high energy consumption, heavy pollution, and intermittent production. development of the rubber industry.
