Problems solved by technology

This kind of rubber material is not ideal for tire repair due to the impact of tire rotation on its action surface, so it cannot be popularized in the automotive field.
In the field of bicycles, electric vehicles and motorcycles, it is required that the cost of rubber materials should not be too high, and the selection of materials is limited. In actual use, steel hubs may be corroded.

Abstract

The invention discloses prick-resistant explosion-proof polymer synthetic high-viscoelasticity rubber for a tyre. The prick-resistant explosion-proof polymer synthetic high-viscoelasticity rubber is a mixture comprising, by weight, 6-50 parts of rubber, 25-70 parts of a binder, 5-25 parts of softening oil, 5-30 parts of SBS resin, 3-25 parts of tackifying resin, 0-15 parts of a filler, 0.5-1 part of an anti-oxidant, 0-0.1 parts of dye and 5-20 parts of a solvent. A preparation method of the prick-resistant explosion-proof polymer synthetic high-viscoelasticity rubber comprises carrying out open milling on rubber through an open mill at a temperature of 40-90 DEG C, adding the rubber, the binder, the softening oil, the SBS resin, the tackifying resin, the filler, the anti-oxidant, the dye and the solvent into a reactor together, heating the mixture to a temperature of 150-250 DEG C through heat conduction oil, carrying out a stirring reaction process through a stirrer for 2-3h, simultaneously, carrying out vacuum pumping and recovering and recycling the volatile solvent. The preparation method has high efficiency and is environmentally friendly. The prick-resistant explosion-proof polymer synthetic high-viscoelasticity rubber has good resilience, good caking properties and aging resistance.

Description

technical field [0001] The invention relates to a high-viscoelastic rubber material and a preparation method thereof, in particular to an anti-puncture and explosion-proof polymer synthetic high-viscoelastic rubber material for tires and a preparation method thereof. Background technique [0002] When driving or cycling, it is often encountered that the tires are punctured and leaking air, which affects our normal travel and work efficiency. In order to avoid similar situations from happening, car owners will have 1 or more tires on the car to prevent such situations from taking place when traveling, and will carry various tools simultaneously in order to change tires. These extra weights not only increase the fuel consumption of the car, but also reduce the effective space utilization in the car. The mileage of electric vehicles and motorcycles is relatively short, and there is room for spare tires and tools. Once a similar situation occurs, the vehicles will not only fail...
