Description

A kind of spraying method of tire polymer memory glue

technical field

The invention relates to a spraying method of a polymer material, in particular to a spraying method of a tire polymer memory glue.

Background technique

At present, the spray-type self-sealing anti-leakage safety tire uses a special equipment to evenly spray a kind of polymer organic memory synthetic rubber on the inner wall of the tire in batches, so that a certain thickness of anti-leakage safety protection zone is formed inside the tire. When the tire is pierced by sharp objects such as nails, the memory glue inside the tire will seal the wound tightly in all directions in an instant, preventing the air in the tire from leaking out. When the nail is pulled out, the memory glue will automatically reset and close, tightly plugging the leak, preventing the tire from leaking, thereby effectively preventing the sudden tire blowout.

During the spraying process of polymer memory glue, the reaction kettle needs to be heated for nearly ten hours, then cooled and stored, and then heated for spraying. Not only can the spraying be uniform, but also the degree of adhesion between the polymer memory glue and the inner side of the tire cannot be guaranteed. , also cause very big waste on manpower and financial resources, therefore it is necessary to invent a kind of spraying method of tire polymer memory glue.

Contents of the invention

Technical scheme of the present invention:

A method for spraying tire polymer memory glue, the steps are as follows:

(1) Clean the inside of the tire to remove the mold release agent, dry it, and then install the tire bladder on the inside of the tire;

(2) Fully stir the tire polymer memory glue to remove air bubbles, and then add it between the tire bladder and the inner side of the tire;

(3) Continuously fill the tire bladder with hot air at 90-110°C at a constant speed, so that the tire bladder continues to expand evenly, and apply pressure to the tire polymer memory glue until the contact surface between the tire polymer memory glue and the tire bladder becomes flat;

(4) Wait until the hot air in the tire bladder cools down to normal temperature, and then maintain the shape for 30 minutes to form a layer of tire polymer memory rubber layer, and then take out the tire bladder to complete the spraying of the tire polymer memory rubber.

The outer layer of the tire bladder is evenly coated with OM paint with a thickness of 2-4mm.

The gap between the tire carcass and the tire bladder is 4-8mm.

The polymer memory glue contains a chemical material that melts at low temperature.
