Embodiment 1

[0021] Anti-aging agent NBC is made from the following raw materials by weight: 53 parts of anti-aging agent NBC, 38 parts of calcium terephthalate, sulfur-containing silane coupling agent bis-[3-(triethoxysilicon)-propyl]-tetra 1 part of sulfide.

[0022] Preparation steps: first, add 38 parts of calcium terephthalate into the reactor; add 53 parts of anti-aging agent NBC to the reactor after crushing and grinding, mix and stir with calcium terephthalate, and control the temperature at 50 degrees; anti-aging After mixing and stirring NBC and calcium terephthalate for 1 hour, add 1 part of sulfur-containing silane coupling agent bis-[3-(triethoxysilyl)-propyl]-tetrasulfide, mix and stir, and finally form The anti-aging agent NBC is fully coated with nanomaterials, and the total reaction time is 2:20.

[0023] The anti-aging agent NBC obtained in this example can completely coat nanomaterials, which ensures the application effect of this product in rubber.

Embodiment 2

[0025] Anti-aging agent NBC is made from the following raw materials by weight: 60 parts of anti-aging agent NBC, 46 parts of calcium terephthalate, and 2 parts of alkyl silane coupling agent tetraethyl silicate.

[0026] Preparation steps: first, add 46 parts of calcium terephthalate into the reactor; add 60 parts of anti-aging agent NBC to the reactor after crushing and grinding, mix and stir with calcium terephthalate, and control the temperature at 60 degrees; anti-aging Agent NBC and calcium terephthalate were mixed and stirred for 1 hour, 2 parts of alkyl silane coupling agent tetraethyl silicate were added, mixed and stirred, and finally a product of anti-aging agent NBC fully coated with nanomaterials was formed, and the total reaction time was 1 40 minutes.

[0027] The anti-aging agent NBC obtained in this example can completely coat nanomaterials, which ensures the application effect of this product in rubber.

Embodiment 3

[0029] Anti-aging agent NBC is prepared from the following raw materials by weight: 55 parts of anti-aging agent NBC, 43 parts of calcium terephthalate, and 2 parts of alkylsilane coupling agent 1,2-bis(triethoxysilyl)ethane.

[0030] Preparation steps: first, add 43 parts of calcium terephthalate into the reactor; add 55 parts of anti-aging agent NBC into the reactor after crushing and grinding, mix and stir with calcium terephthalate, and control the temperature at 58 degrees; After mixing and stirring NBC and calcium terephthalate for 1 hour, add 2 parts of alkylsilane coupling agent 1,2-bis(triethoxysilyl)ethane, mix and stir, and finally form an all-inclusive antioxidant NBC For products coated with nanomaterials, the total reaction time is 1:45.

[0031] The anti-aging agent NBC obtained in this example can completely coat nanomaterials, which ensures the application effect of this product in rubber.

Abstract

The invention discloses an anti-aging agent NBC coated with a nanomaterial and a preparation method of the anti-aging agent NBC. The anti-aging agent NBC is prepared from the following raw materials: an anti-aging agent NBC, the nanomaterial and a silane coupling agent. The preparation method comprises the following steps of firstly, adding the nanomaterial in a reactor; secondly, crushing and grinding the anti-aging agent NBC and then adding the powder into the reactor, mixing and stirring the powder with the nanomaterial, and controlling the temperature at 50 to 60DEG C; thirdly, mixing and stirring the anti-aging agent NBC with the nanomaterial for one hour, then adding the silane coupling agent, and performing mixed stirring treatment to finally form an anti-aging agent NBC product which is fully coated with the nanomaterial. The anti-aging agent NBC product obtained by the preparation method disclosed by the invention can be fully coated with the nanomaterial, so that the application effect of the product in rubber is guaranteed.

Description

technical field [0001] The invention relates to an antioxidant NBC and a preparation method thereof, in particular to an antioxidant NBC coated with nanometer materials and a preparation method thereof. Background technique [0002] Anti-aging agent NBC is a special nickel-based anti-aging agent used in tire rubber. The pure product content of this product is about 92%, dark green powder, generally packed in 25 kg, and the pure product is extruded after storage. It is easy to agglomerate, and it is inconvenient to feed materials during the rubber mixing process. Even after crushing, it may still be mixed in the form of small particles. The NBC in the coated particles cannot play an anti-aging effect, resulting in waste of materials and increased dosage; in addition, The price of pure NBC antioxidant is high, which increases the cost. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an anti-aging agent NBC coated with nanomaterials and a...
