Embodiment Construction
[0023] Such as figure 1 , 2 A kind of ultra-low-section color-character tire shown in . area, font design area, and rim joint area, the tread of the font design area is composed of sidewall rubber 6, color rubber 7 arranged in the sidewall rubber, non-polluting sidewall rubber 8 for covering color rubber, and The wear-resistant rubber 9 connected by the sidewall rubber is composed of a steel traveler 10 and an apex rubber 11 wrapped in the carcass in the rim joint area.
[0024] The preparation method of the ultra-low-section color-character tire is as follows: firstly increase the sidewall space design, and carry out the sidewall pre-mouth shape and mouth shape design according to the material distribution requirements; Cover color glue, adopt different construction designs according to different molding methods; adopt special process control to prevent color font defects; special color glue design ensures product performance;
[0025] The design of enlarging the sidewall ...

A colorized-character tyre with ultralow cross sections is disclosed. The tyre comprises an inner liner, a tyre body, a belt ply layer, a crown belt and a tread which are connected in order. The tread is divided into a parting zone, a character design zone and a rim seat zone. The tread in the character design zone comprises sidewall rubber, colored rubber in the sidewall rubber, non-staining sidewall rubber used for covering the colored rubber and wear-resistant rubber connected to the sidewall rubber. The tread in the rim seat zone covers steel wire rings and triangle rubber. A preparing method of the tyre is also disclosed. According to the tyre and the method, colored characters can be produced at side walls of the tyre, the tyre is beautiful in appearance, inner material distribution of a product is reasonable, and the tyre has excellent properties. Through optimizing a formula design of the colored rubber, the colored rubber is bright and beautiful in appearance color and good in adhesion effects with surrounding black rubber, and quality problems such as delamination are not liable to occur.
Description
technical field [0001] The invention relates to a tire and a preparation method thereof, in particular to an ultra-low-section colorful word tire and a preparation method thereof. Background technique [0002] The common color tires in the market are generally larger SUV and light truck tires. This type of tire has a high cross-section, sufficient sidewall space, and relatively simple design and production. It can be produced by ordinary tire companies. However, with the continuous upgrading of automobile products, there are more and more low-section tire products, especially the ultra-low-section tires have small sidewall space. The rubber material in the side part is complex, which may easily cause abnormal distribution of product materials and affect product performance. [0003] Therefore, there is a need for a preparation method that can not only produce colored fonts on the sidewalls of ultra-low-section tires with a dazzling appearance, but also make the internal mat...
