Embodiment 1

[0045] 1) Use Yangbi walnut shells, jatropha shells, bagasse, Yunnan pine bark, eucalyptus branches, and Camellia oleifera pomace to be crushed to a size greater than or equal to 120 mesh, according to mass percentage. Components: Yangbi walnut shell powder: Jatropha shell powder : Bagasse powder: Yunnan pine bark powder: Eucalyptus branch powder: Camellia oleifera pomace powder = 40:10:10:15:15:10 to prepare component A and mix evenly.

[0046] 2) Use waste oil regenerated grease, castor oil, and tung oil, and prepare component B according to mass percentage: castor oil: tung oil = 80:10:10, and mix well.

[0047] 3) Apply components A and B to design desulfurization of tire reclaimed rubber. When using high temperature and high pressure dynamic desulfurization process (temperature: 220°C, pressure: 3.0MPa, desulfurization time: 70min), the desulfurization formula is designed as follows: rubber powder (30 mesh): A component: B component: dipentene: rosin: activator 420=85:10:...

Embodiment 2

[0050] 1) Use Yangbi walnut shells, jatropha shells, bagasse, Yunnan pine bark, eucalyptus branches, and Camellia oleifera pomace to be crushed to a size greater than or equal to 120 mesh, according to mass percentage. Components: Yangbi walnut shell powder: Jatropha shell powder : Bagasse powder: Yunnan pine bark powder: Eucalyptus branch powder: Camellia oleifera pomace powder=50:5:10:15:15:5 Prepare component A and mix evenly.

[0051] 2) Use waste oil regenerated grease, castor oil, and tung oil, and prepare component B according to the mass percentage of waste oil regenerated grease: castor oil: tung oil = 90:5:5, and mix well.

[0052] 3) Use components A and B to design the desulfurization of tire reclaimed rubber. When using high temperature and high pressure dynamic desulfurization process (temperature: 200°C, pressure: 2.5MPa, desulfurization time: 80min), the desulfurization formula is designed as follows: rubber powder (30 mesh): A component: B component: dipentene...

Embodiment 3

[0055] 1) Use Yangbi walnut shells, jatropha shells, bagasse, Yunnan pine bark, eucalyptus branches, and Camellia oleifera pomace to be crushed to a size greater than or equal to 120 mesh, according to mass percentage. Components: Yangbi walnut shell powder: Jatropha shell powder : Bagasse powder: Yunnan pine bark powder: Eucalyptus branch powder: Camellia oleifera pomace powder = 60: 20: 5: 5: 5: 5 to prepare component A and mix evenly.

[0056] 2) Use waste oil regenerated grease, castor oil, and tung oil, and prepare component B according to the mass percentage of waste oil regenerated grease: castor oil: tung oil = 90:5:5, and mix well.

[0057] 3) Apply components A and B to desulfurize reclaimed rubber for rubber shoes. When using high temperature and high pressure dynamic desulfurization process (temperature: 190°C, pressure: 2.0MPa, desulfurization time: 50min), the desulfurization formula is designed as follows: rubber powder (20 Mesh): A component: B component: rosin...

Abstract

Disclosed is a plant reclaimed rubber softener formula. The formula comprises an A component and a B component, wherein the A component is a powder component and comprises walnut shell powders, jatropha curcas shell powders, bagasse powders, pine bark powders, eucalyptus branch powders and oil camellia pomace powders, and the B component is an oil component and comprises a waste edible oil regeneration oils and fats, castor oil and jatropha curcas oil. The plant reclaimed rubber softener formula has the advantages that the permeability and heat expansibility of the obtained softener during the desulfurization process and viscosity and plasticity of desulfurization reclaimed rubber materials are compared with identical characteristics of solid coal tar during the desulfurization process, and thereby the plant reclaimed rubber softener formula with the property superior to that of the solid coal tar is obtained.

Description

technical field [0001] The invention belongs to the technical field of reclaimed rubber processing, and in particular relates to the formulation and application of plant-based regenerated rubber softener. Background technique [0002] Reclaimed rubber mainly means that waste rubber products undergo physical and chemical processes such as crushing, heating, and mechanical treatment to remove the elasticity of vulcanized rubber and restore plasticity and viscosity, so that it can regain the ability to mix and vulcanize with raw rubber, so that it can be reused in the rubber industry. A kind of rubber raw material in. The recycling of waste rubber can not only save a lot of rubber resources, but also reduce environmental pollution. [0003] At present, reclaimed rubber has been widely used in tires, rubber hoses, conveyor belts, bicycle tires, rubber shoes, rubber sheets, etc. In addition, it is also used in building materials, such as linoleum, cold-applied coils, waterproof...
