Problems solved by technology

However, due to the particularity of the raw materials, the above-mentioned ordinary polymer patch can only be made into a polymer patch with a thickness of 3.5mm or more according to the current production method and process. The thickness is too high, resulting in the heavy weight of the patch
After the ordinary polymer patch is applied to repair the inner wall of the tubeless tire, a large bump is formed at the repaired position, which affects the dynamic balance of the wheel, and is prone to tangential displacement during the running of the wheel, that is, the wheel rotates Due to the centrifugal force formed and the inertial effect when starting or braking, the patch may slide and shift, which cannot fully cover the air leakage point of the carcass, and secondary air leakage occurs from time to time

Abstract

The invention relates to the field of production and application technologies of polymer memory rubber, specifically to a polymer memory rubber tire cold patch and production equipment and a production technology thereof. A common polymer patch has excessive thickness and excessive dead load, which influence dynamic balance of wheels and easily lead to tangent displacement and secondary leakage. The invention provides a tire cold patch prepared from polymer memory rubber. The cold patch is light and durable in use, and the tire repair operation is simple and fast. In addition, the cold patch has a good tire repair effect and is not easy to cause displacement and shedding. The polymer patch comprises a base layer, a rubber layer and a release paper layer. The thickness of the rubber layer is 0.1-1.8 mm. The product is used for repairing of pneumatic tires for passenger vehicles and buses. The cold patch of the invention is light, thin and durable in use, requires no polishing treatment,is simple, convenient and fast to operate, is not easily influenced by the centrifugal force generated by rotation of tires to shift, and can effectively avoid secondary repairing of tires.

Description

technical field [0001] The invention relates to the technical field of production and application of polymer memory rubber, in particular to a polymer memory rubber tire cold patch and its production equipment and production process. Background technique [0002] Tire repair is a situation often encountered in the use of pneumatic tires. Today's road conditions and tire technology still require tire repair for damaged tires. Tire repair technology has also been greatly developed. From patch tire repair From the mushroom nail tire repair, to the later preventive tire repair technology, it has really changed people's lives. [0003] Generally speaking, the methods of patching bad tires can be roughly divided into three types according to the degree of tire damage: cold patching (internal patching or pasting patching), hot patching (commonly known as fire patching) and rubber strip method. The so-called cold repair is to remove the injured tire from the rim, find the wound, cl...
