Embodiment 1

[0043] The mass percentage of rubber filler is specifically:

[0044] Modified powdery solids: 74wt%

[0045] Carbon black: 17wt%;

[0046] Benzoyl peroxide: 2wt%;

[0047] Zinc oxide: 2wt%%;

[0048] Stearic acid: 1wt%;

[0049] N'-m-phenylene bismaleimide: 1 wt%.

[0050] 2-mercaptobenzothiazole: 1.4wt%;

[0051] N,N'-di-o-toluidine: 0.6 wt%.

[0052] N-Cyclohexyl-N'-phenyl-p-phenylenediamine: 1wt%

[0053]In this example, the preparation process of the modified powdery solids is as follows: the oily solids raw material B scum is sent to a screw stacker for mechanical dehydration, and the water content is reduced to 73.7wt%; the dehydrated oily solids are sent to pretreatment The tank is fully mixed with the pretreatment agent, and the amount of the pretreatment agent is 3.5 times that of the oil-containing solids, and the solid-liquid separation can be achieved after standing or centrifuging. The solid-phase material obtained by separation enters the treatment tank ...

Embodiment 2

[0055] The mass percentage of rubber filler is specifically:

[0056] Modified powdery solids: 77wt%

[0057] Carbon black: 13.5wt%;

[0058] Benzoyl peroxide: 1.5wt%;

[0059] Zinc oxide: 3wt%%;

[0060] Stearic acid: 1.5wt%;

[0061] 2-mercaptobenzothiazole: 1.3wt%;

[0062] Thiuram disulfide: 0.2wt%;

[0063] N-(1,3-Dimethyl)butyl-N'-phenyl-p-phenylenediamine: 2 wt%.

[0064] In this embodiment, the preparation process of the modified powdery solids is as follows: the oily solids raw material B scum is sent to the screw stacker for mechanical dehydration, and the water content is reduced to 71.5wt%; the dehydrated oily solids are sent to the pretreatment The tank is fully mixed with the pretreatment agent. The amount of the pretreatment agent is twice that of the oil-containing solid material. After standing or centrifuging, the solid-liquid separation is realized. The separated solid phase material enters the treatment tank and is fully mixed with the treatment agent...

Embodiment 3

[0066] The mass percentage of rubber filler is specifically:

[0067] Modified powdery solids: 70wt%

[0068] Carbon black: 20wt%;

[0069] Benzoyl peroxide: 2.5wt%;

[0070] Zinc oxide: 1.5wt%;

[0071] N'-m-phenylene bismaleimide: 3wt%;

[0072] N-tert-butyl-2-benzothiazole sulfenamide: 1.8wt%;

[0073] Thiuram monosulfide: 0.2wt%;

[0074] N,N'-diphenyl-p-phenylenediamine: 1 wt%.

[0075] In the present embodiment, the preparation process of the modified powdery solid is as follows: the oil-containing solid raw material (the raw material A and the raw material B are mixed in a weight ratio of 1:10) is sent to the screw stacker for mechanical dehydration, and the moisture content is reduced to 68.2wt%; The dehydrated oil-containing solids are sent to the pre-treatment tank, and fully mixed with the pre-treatment agent. The amount of the pre-treatment agent is 4 times that of the oil-containing solids. After standing or centrifuging, solid-liquid separation is achieved....

Abstract

The invention discloses an environment-friendly rubber filler and a preparation method thereof. The rubber filler comprises a modified powdery solid, carbon black, a vulcanizing agent, an activator, an auxiliary vulcanizing agent, a vulcanization accelerator and an anti-aging agent. The preparation method of the environment-friendly rubber filler is to mix the modified powdery solid matter, carbon black, vulcanizing agent, cross-linking agent, auxiliary vulcanizing agent, vulcanization accelerator and anti-aging agent uniformly in proportion. The present invention utilizes the powdery solids obtained after the oil-containing solids are processed to replace the mineral powder used in the existing rubber filler, which can not only improve and enhance the rubber properties, but also solve the problem of environmental pollution caused by the oil-containing solids, and realize the resource utilization of the oil-containing solids. It has significant economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and particularly relates to an environment-friendly rubber filler and a preparation method and application thereof. Background technique [0002] As a kind of natural polymer material with excellent comprehensive performance and renewable, natural rubber has the advantages of high strength, elasticity, insulation performance, good wear resistance, etc. It is widely used in aerospace, national defense, automobile industry, medical and health industries , occupies a very important position in industrial production and national life. Filler is the main auxiliary agent of rubber, which can give rubber many excellent properties. Powder (granular) fillers are still commonly used fillers. Its function is to improve the hardness and mechanical properties of rubber products, such as tensile strength, tensile stress, etc.; at the same time, it can also improve process performance and redu...
