Embodiment 1

[0042] A kind of rubber additive, its chemical structural formula is:

[0043]

[0044] The preparation method of above-mentioned metallic soap, comprises the following steps:

[0045] (1) Add 1L distilled water and 16g sodium hydroxide solid (purity ≥ 97%, purchased from TCI) in a 2L beaker, after the sodium hydroxide is completely dissolved, add 78.88g levodopa (DOPA) (purity ≥ 99%) %, purchased from Aladdin). The above mixture was heated to 90 °C and stirred vigorously for 1 hour until the solution was completely transparent. (Solution A)

[0046] (2) Another 2L beaker was taken, and 1L of distilled water and 94.8g of potassium aluminum sulfate dodecahydrate (purity ≥ 99%, purchased from Aladdin) were added into it. The above mixture was heated to 90 °C and stirred vigorously for 1 hour until the solution was completely transparent. (Solution B)

[0047] (3) Finally, in the case of vigorously stirring solution A, slowly pour solution B into solution A at a speed of ...

Abstract

The present invention relates to a rubber additive and its preparation and application. The chemical structural formula of the rubber additive is: wherein, M is a metal whose oxidation state is +3 or +4, and R 1 is the aliphatic chain of C5‑C50, R 2 , R 3 and R 4 It is an aliphatic chain with 0 to 50 carbon atoms, and the amino group can be connected to R in the form of primary, secondary or tertiary ammonia. 2 , R 3 and / or R 4 Above, x is 1 or 2, y is 0 or 1, and the sum of x and y is 2. When the rubber additive of the present invention is used for rubber preparation, the obtained rubber additive can also significantly enhance the tensile strength and wet skid resistance of the rubber.

Description

technical field [0001] The invention relates to the field of tire rubber additives, in particular to a rubber additive and its preparation and application. Background technique [0002] Wet skid resistance is an important indicator of tires. When the car is running on a road with water, the grip of the tires will be greatly reduced due to the presence of water. This not only affects the traction of the car, but also affects the braking distance of the car during emergency braking and affects the safety of driving. Therefore, wet skid resistance is an important index to measure the wet traction and driving safety of tires. [0003] Mussels in the wild are often stuck to the surface of rocks and reefs, showing a strong adhesive force, not only on the surface of stones, but also often on the outer metal surface of the hull, on glass, mica, quartz, wood, etc. The surfaces of commonly used materials such as plastics and plastics have good adhesion, and can even stick to the su...
