Technical Field

The invention relates to the field of new materials, and particularly provides a reflective tire with a reflective material adhered to the side surface of the tire and a preparation method thereof.

Background

At present, there are several approaches to improve safety and visibility

1) Warning light or light: this method is the most effective and effective way in the vehicle starting process, however, the warning effect disappears when the power supply is interrupted, the bulb is damaged or the vehicle is not started, resulting in a sharp reduction in safety.

2) The automobile body pastes reflector panel, and this material back of the body is laid pressure sensitive adhesive layer, and is higher to the clean requirement in the automobile body surface of pasting, otherwise has the insecure and upwarps and the scheduling problem that drops easily of pasting, and the fastness and the compatibility of pressure sensitive adhesive and tire make this reflective membrane can't firm adhesion in the tire side simultaneously.

CN93106393 discloses a night safety reflective tire, which is formed by embedding a reflective sheet on the side surface of the tire, wherein the reflective sheet is composed of a glass bead layer, a metal plating layer, a resin coating layer, a fiber reinforcement layer and a rubber resin base layer. The reflector is then fitted to the tire by vulcanization. The preparation process is complex, the processes are multiple, and the raw material and production cost are inevitably increased. Which necessitates peeling off the carrier film layer before co-curing the reflector with the tire. Then the reflective sheet with the exposed reflective surface and the tire are vulcanized at high temperature and high pressure, and the reflective part can be extruded and deformed and even can be adhered to a mold, so that greater loss is caused. And because the glass beads are exposed outside, the glass beads are difficult to clean when being polluted by mud or even oil stains, and the reflecting effect is lost.

CN100522664 discloses a reflective bicycle tire, which embeds reflective material in the pattern gaps of the bicycle tire, the manufacturing process is complicated, and the reflective effect is more easily reduced or lost due to mud or oil contamination in the pattern gaps of the tire.

Therefore, there is a need for a reflective material for automobile tires, which is simple in manufacturing process, less prone to contamination by oil stains, and easy to clean.

Disclosure of Invention

The invention aims to provide a tire with a light reflecting part and a preparation method thereof, which are integrally formed with the tire, and have the advantages of good fastness, wear resistance, stable and durable light reflecting effect, simple structure, stable process and relatively low cost.

The invention aims to provide an automobile reflective tire with a reflective part having self-cleaning capability and a preparation method thereof, so that the reflective tire is not easy to be polluted by mud or oil stains to influence the reflective effect, and the mud and oil stains can be cleaned by simple washing or rainwater washing even after the reflective tire is polluted by the mud or oil stains.

The invention also aims to provide the automobile reflective tire with good weather resistance, good bending resistance and good fastness and the preparation method thereof.

The invention relates to an automobile reflective tire, which is formed by compounding a reflective layer on the surface of a tire, wherein the reflective layer consists of a glass bead layer, a self-cleaning layer, a reflective layer and a resin layer.
