Abstract

The invention relates to a rubber additive as well as preparation and application thereof. The chemical structural formula of the rubber additive is as shown in the specification, wherein M is a metal with the oxidation state of +3 or +4, R1 is a C5-C50 aliphatic chain, and R2, R3 and R4 are aliphatic chains with the carbon atomic number of 0 to 50; an amino is connected to the R2, the R3 and / or the R4 in the form of primary ammonia, secondary ammonia or tertiary ammonia; x is 1 to 2; y is 0 to 1; the sum of the x and the y is 2. The rubber additive provided by the invention is used when rubber is prepared; the obtained rubber additive can also enhance the tensile strength, the wet skid resistance and the like of the rubber remarkably.

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...
