Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] figure 1 Shown is the structural representation of the airfoil tread rubber of the present invention. The tread rubber base rubber 1 is the base of the existing planar tread rubber, and the surface of the upper part of the tread rubber base rubber 1 is provided with a tread pattern, which is the same as the tread pattern of the existing tire and is a well-known technology, so it is not shown in the drawings. Wing-shaped rubber wings 2 are respectively arranged on both sides of the tread rubber base rubber 1, and the rubber wings 2 extend to both sides along the tread rubber base rubber 1. The rubber wings 2 shown in the figure extend in parallel, and the rubber wings 2 can also be Made into arc shape or other space sheet structure.

[0030] figure 2 Shown is the structure diagram when the airfoil tread rubber of the present invention is attached to the tire...

Abstract

The invention provides a new type of pre-vulcanized tread rubber, including the tread rubber itself, characterized in that: the tread rubber is provided with wing-shaped rubber fins extending outward on both sides of the base rubber. The invention also provides an application method of the precured tread rubber. The application of the invention can greatly simplify the operation of tire retreading, and reduce the investment and production cost of retreading tire equipment.

Description

technical field [0001] The invention relates to the technical field of tire retreading, in particular to a novel prevulcanized tread rubber for tire retreading and a method for retreading tires using the tread rubber. Background technique [0002] During the long-term operation of the tire, the friction with the ground will quickly wear out the rubber layer on the surface, especially when the tread with various groove patterns on the surface of the carcass wears to a certain extent, the pattern will not be able to effectively guarantee There is enough friction between the wheels and the ground, so the car is easy to slip or the braking distance is too long during driving, which seriously reduces the safety performance of the car. The traditional method is to replace the tires. If the abandoned waste tires cannot be effectively used, it will not only damage the The surrounding environment causes pollution, and it also causes a huge waste of existing resources. [0003] At pr...
