Embodiment Construction

[0017] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, features and effects of the present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0018] The invention provides a kind of preparation method of modified rubber, comprising steps:

[0019] After irradiating high-performance short fibers under ultraviolet light for a period of time, add them to ethanol, and make a uniformly dispersed fiber suspension by stirring;

[0020] Add a coupling agent to the prepared fiber suspension, adjust the pH to 8-9, react at room temperature for 2-4 hours, then add sodium dodecylbenzenesulfonate, and continue to react for 1-2 hours to obtain a reaction solution. Suction filtration under reduced pressure to remove the liquid in the reaction solution to obtain the modified fiber slurry;

[0021] Adding the modi...

Abstract

The invention provides a preparation method of modified rubber and the modified rubber. In the method, high-performance short fibers are irradiated under ultraviolet light to introduce active groups into the high-performance short fibers, and then the high-performance short fibers are modified with a coupling agent so as to increase the compatibility between the high-performance short fibers and a rubber matrix; finally, by means of charge repulsion effect of lauryl sodium sulfate, agglomeration of the high-performance short fibers in the rubber matrix is effectively avoided, which is beneficial to production of the modified rubber. In a bulletproof and puncture-proof tyre produced from the modified rubber, a buffer layer in the tyre is produced with the modified rubber, at least one of a tread, a belted layer and an airtight layer is produced with the modified rubber, and a cord fabric layer of the tyre is produced by weaving twisted high-performance long fibers, so that the tyre has bulletproof and puncture-proof functions, is light in weight and brings stable performance to driving.

Description

technical field [0001] The invention relates to the technical field of composite materials for automobiles, and in particular to a preparation method of modified rubber, modified rubber and bulletproof and puncture-resistant tires. Background technique [0002] Tire refers to a circular elastic rubber product that rolls on the ground and is assembled on various vehicles or machinery. It is usually installed on the metal rim, which can support the body, buffer the external impact, realize the contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperatures while driving. They must have high load-bearing, traction, and cushioning properties. Complicated terrain and wartime requirements for wheeled vehicles urgently require the development of a new type of bulletproof and anti-puncture tire. At present, the existing ...
