Problems solved by technology

Although the material of this structure can solve the problem of tire puncture resistance, the process is relatively complicated and the cost is relatively high because the first material used must be combined on the base material of a layer of polyaramid stick

Embodiment Construction

[0034] figure 1 It is a structural schematic diagram of an ordinary tire that does not have the puncture-resistant function in the prior art, and its defects have been described above, and will not be repeated here.

[0035] refer to figure 2 , The puncture-resistant tire of the present invention includes a tread 1 and a carcass, and the carcass is composed of a skeleton 2 , an inner surface layer 5 and a steel wire coil 4 . A layer of puncture-resistant material 3 is provided between the tread 1 and the frame 2, and the puncture-resistant material 3 is a composite material based on high styrene. The composite material is a mixture of high styrene rubber, natural rubber and fillers. The weight ratio of each component is high styrene rubber 20-30%, natural rubber 20-30%, and the rest is filler. The filler is a mixture of 70-80%wt carbon black and 20-30%wt processing aid.

[0036] refer to image 3 , the preparation of the puncture-resistant tire of the present invention i...

Abstract

The invention discloses a pricking resistance tire, comprising a tread and a tire casing, which is characterized in that the tread and the tire casing are provided with a layer of pricking resistance material which is composite material based on high styrene. The pricking resistance tire of the invention is prepared by the following steps: preparing rubber compound; processing fabrics, coating casing ply rubber compound and clipping; extruding or calendering the rubber compound of the tread and the pricking resistance material, cutting and cooling the rubber compound; processing a steal loop; assembling into a tire rough; solidifying. The pricking resistance tire has the advantages of pricking resistance, high elasticity, simple process, high recovery rate of leftover materials, low cost, little occupied equipment, low energy consumption, etc.

Description

technical field [0001] The invention relates to a tire, in particular to a vehicle pneumatic tire, in particular to a puncture-resistant tire and a preparation method thereof. Background technique [0002] Motor vehicles have already become a common means of transportation for the general public, regardless of their comfort and safety, they are all indispensable elements. [0003] Tires are an important safety component of motor vehicles. In the process of driving, if the road conditions are not good, when you accidentally encounter iron nails, glass or other sharp objects on the road surface, it will often make driving in a dangerous state. [0004] At present, there are several kinds of anti-stab technical solutions for pneumatic tires: [0005] Option 1: as in Chinese patent CN2418031, it is a solution to increase the inner cushion layer. The inner cushion layer is post-processed and arranged in the inner surface layer of the tire, so the tire processing is not a one-t...
