Description

High-resilience super-fatigue-resistance environment-friendly rubber and preparation method thereof
Technical Field
The invention relates to a rubber material more suitable for rubber used for tire sidewall parts, in particular to a high-resilience super-fatigue-resistance environment-friendly rubber and a preparation method thereof.
Background
Many run-flat tires used in the current market have high vehicle shake and poor riding comfort due to too high hardness of the tire side wall in uneven road surfaces passing through some ditches and the like after being used; after the tire continues to run for more than 300 km when the tire loses pressure, fatigue lines start to appear on the side wall of the tire, so that the normal service life of the tire is influenced, and a lot of potential safety hazards are caused or the tire is scrapped in advance to cause social energy waste. In order to solve such a problem, there is a need for improving the performance of tire sidewall rubber to have high rebound resilience and super fatigue resistance.
CN201710303543.4 "preparation method of gutta percha and rubber compound for normal temperature molding processing", natural rubber or synthetic rubber is banburying and then adding auxiliary agent to prepare raw rubber master batch, gutta percha is banburying and then adding auxiliary agent to prepare gutta percha rubber compound in an internal mixer at 50-70 ℃, then the gutta percha rubber compound and the raw rubber master batch are uniformly mixed at 25-35 ℃ to obtain gutta percha and rubber compound for normal temperature molding processing; the technology illustrates the preparation of gutta-percha formed and processed at normal temperature, only the preparation of the compound rubber is reflected, the subsequent use is not studied, and in fact, the compound rubber prepared by the scheme is still too hard at normal temperature, and the compound rubber can not meet the requirement of manual forming operation in the production process of the tire only when the compound rubber is operated at high temperature in the forming stage of the tire.
CN201710303923.8 (gutta percha delta rubber for tyre and preparation method thereof) plasticates gutta percha at 55-65 ℃ for about 3 minutes, and then mixes the gutta percha with the plasticated natural rubber, adds auxiliary agent to mix, and then sets the mixture at room temperature for a period of time, and then returns to be 2-8 minutes at 55-65 ℃ and extrudes to obtain the delta rubber; the application of gutta percha on the triangular rubber of the tire is illustrated in the technology, the Shore A hardness is 73-99, and the bending resistance performance is 18-24 ten thousand times and can be broken. In order to ensure the retention of the bead shape, it is necessary to use a high hardness state of 80 to 95 (shore a), and the high rebound resilience is obtained, but the flexural fatigue resistance is extremely poor.
CN201610223217.8 (a natural fatigue-resistant eucommia ulmoides vulcanized rubber and a preparation method thereof) plasticates natural rubber and eucommia ulmoides rubber at 55-65 ℃, adds auxiliary agents for mixing, sets the rubber at room temperature, then remills at 55-65 ℃, then carries out vulcanization at 145-155 ℃, and cools to obtain the fatigue-resistant eucommia ulmoides rubber and the combined rubber vulcanized rubber thereof, wherein the Shore A hardness is 68-73, and the fatigue life reaches 20 ten thousand times; the technology illustrates that the gutta percha can be prepared into fatigue-resistant vulcanized rubber after plasticating at low temperature, is mainly used for damping products, and cannot be suitable for flexing and fatigue resistance of the tire application requirements in a high-frequency state.
Eucommia ulmoides rubber is a natural high polymer material produced by Du Zhongshu, is an isomer with the natural rubber, and mainly comprises trans-1, 4-polyisoprene; gutta percha has been widely used in vulcanized rubber, but the rebound resilience and fatigue resistance of the product do not meet the requirements of tire sidewall rubber.
