Problems solved by technology

[0002] At present, the total amount of solid fertilizers such as domestic waste, industrial waste, and construction waste is increasing day by day, and the phenomenon of "garbage siege" has become increasingly prominent. Tires are circular elastic rubber products that roll on the ground and are assembled on various vehicles or machinery. With the continuous development of society and the continuous progress of industry, there are more and more solid wastes represented by discarded rubber tires. The current treatment methods all have the defects of environmental pollution and waste of resources. Therefore, it is necessary to develop a method that can solve the above technical problems. Recycling method is very necessary

preparation example Construction

[0023] The preparation method of the modified rubber that recycles waste rubber tires according to the present invention includes batching, desulfurization and post-processing steps, specifically including:

[0024] A. Batching: batching according to the formula ratio to obtain material a;

[0025] B. Desulfurization: Add material a to the desulfurization tank for dynamic desulfurization, that is, add steam to the desulfurization tank with material a to a pressure of 0.6~0.8MPa, then heat to 200~250°C to control the pressure to 1.5~2.5MPa, and then After heat preservation and pressure holding for 60-100 minutes, start to exhaust steam until the pressure in the tank is 0, open the tank mouth and discharge materials to obtain desulfurized rubber powder b;

[0026] C. Post-processing: The desulfurized rubber powder b is kneaded, kneaded and refined to obtain the target modified rubber.

[0027] The present invention will be further described below with specific implementation ca...

Embodiment 1

[0029] The waste rubber tire is cut into strips with a width of 3cm by a strip cutter to obtain rubber strip a; the rubber strip a is cut into small pieces of 3cm×3cm in size by a cutter to obtain rubber block b; the rubber block b is Crushing and two-stage magnetic separation to separate metal objects to obtain the target waste tire rubber powder. The magnetic field strength of the two-stage magnetic separation is specifically: the magnetic field strength of the first-stage magnetic separation is 4000Gs; the magnetic field strength of the second-stage magnetic separation is 4000Gs .

Embodiment 2

[0031] Cut the waste rubber tires into strips with a width of 8cm through a strip cutter to obtain rubber strip a; cut the rubber strip a into small pieces of 5cm×5cm in size through a dicing machine to obtain rubber block b; Crushing and two-stage magnetic separation to separate metal objects to obtain the target waste tire rubber powder. The magnetic field strength of the two-stage magnetic separation is specifically: the magnetic field strength of the first-stage magnetic separation is 6000Gs; the magnetic field strength of the second-stage magnetic separation is 2000Gs .

Abstract

The invention discloses a modified rubber recycling waste rubber tires and a preparation method thereof. The modified rubber recycling the waste rubber tires is prepared from, by weight, 50-150 partsof waste tire rubber powder and 2-7 parts of a modifier. The preparation method comprises the steps of compounding, desulfurization and aftertreatment. Accordingly, solid waste of the waste rubber tires is fully recycled, the potential value of the solid waste ( the waste rubber tires) is fully explored, and meanwhile the technical problems of environmental pollution and resource waste are solved;the true value of the waste solid waste is greatly played, a solid foundation is laid for environmental protection, and meanwhile the economic benefit is improved.

Description

technical field [0001] The invention belongs to the technical field of waste recycling, and in particular relates to a modified rubber for recycling waste rubber tires and a preparation method thereof. Background technique [0002] At present, the total amount of solid fertilizers such as domestic waste, industrial waste, and construction waste is increasing day by day, and the phenomenon of "garbage siege" has become increasingly prominent. Tires are circular elastic rubber products that roll on the ground and are assembled on various vehicles or machinery. With the continuous development of society and the continuous progress of industry, there are more and more solid wastes represented by discarded rubber tires. The current treatment methods all have the defects of environmental pollution and waste of resources. Therefore, it is necessary to develop a method that can solve the above technical problems. Recycling methods are very necessary. Contents of the invention [...
