Problems solved by technology

At the same time, it is used together with soft carbon black N683, and carbon black with a larger particle size replaces some other carbon blacks to overcome the defects in the performance of a single type of carbon black; 2. For petroleum-based softeners, choose alkane oils instead of aromatic hydrocarbons, It can make the loss factor of the rubber material smaller and the heat generation lower; 3. Within a certain dosage range, the increase in the amount of accelerator and sulfur can increase the crosslinking density of the vulcanized rubber, which results in an increase in the dynamic elastic modulus and a reduction in the loss factor. 4. Anti-aging agents IPPD and TMQ are used together, and the heat, oxygen, flex cracking and ozone resistance of the products are significantly increased; , the use of PLC automatic control by injection method, the factors of reasonable control of the dispersion of the compound rubber, and further ensure that the formula design is well realized in the process

Abstract

The invention discloses a bushing rubber prepared raw material under lightening development of high-end cars. The bushing rubber prepared raw material comprises the following components in parts by weight: 80 to 90 parts of natural rubber, 10 to 20 parts of butadiene rubber, 2 parts of naphthenic oil, 3.5 parts of zinc oxide, 2 parts of anti-aging agent IPPD (isopropyl-phenyl-paraphenylene diamine), 1 part of anti-aging agent TMQ (trimethyl dihydroquinoline), 2 to 3 parts of microcrystal wax, 6 parts of carbon black N683, 27 parts of carbon black DUREXO, 1.7 parts of sulfur, 1.5 parts of activating agent Struktol ZEH-DL and 1.82 parts of accelerating agent. With the adoption of the bushing rubber prepared raw material under lightening development of the high-end cars prepared by the prepared raw materials, the presulfiding effect and the anti-aging performance of a rubber material can be effectively improved, and the product durability is improved.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to a bushing rubber preparation raw material under the background of lightweight development of high-end cars. Background technique [0002] The good damping characteristics and vibration damping characteristics of rubber materials make it have good shock absorption, sound insulation and buffering functions, which can help the shock absorber to cross the resonance zone. When the rubber compound is subjected to moderate cyclic strain, such as 1-20% compressive strain or 3 times the shear strain, there will be a continuous process of network destruction and recombination. In each strain cycle, progressively higher strains will break the inter-aggregate bonds starting with the weakest bonds. The stronger bonds are then broken, and as the specimen deforms, the aggregates form new bonds at new locations, and these bonds are broken and reformed again in a hysteresis process th...
