Problems solved by technology

At present, after car tires are generally damaged, except for those that can be repaired, they can only be replaced again, and the discarding of waste tires has caused a waste of resources on the one hand, and polluted the environment on the other hand.
Under the existing tire retreading technology, there are fewer and fewer tires that can meet the retreading standard, causing a large number of tires to be discarded, and the tires that are barely retreaded have a high blowout rate, poor balance, difficult to control quality, and endanger life safety.

Embodiment Construction

[0015] A kind of old tire retreading method of the present invention comprises the following steps:

[0016] (1) Screen out the carcass that can be retreaded; the tire inspection machine can be used to inspect the damage, aging and wear of the old tire, or it can be inspected manually.

[0017] (2), cutting and grinding the surface of the carcass to remove the aging rubber layer on the surface; grinding the tire crown

[0018] to a certain size to remove fouled tread.

[0019] (3) Fill the holes on the tread with cushion glue, sew up the gap, fill the seam with cushion glue, and reinforce the seam inside the tread with a liner; The holes are plugged and the cracks are stitched shut. Make initial repairs.

[0020] (4) Clean the carcass treated in step 3, use a vacuum device to dry the water remaining on the carcass, and spray adhesive glue on the tread in a vacuum state; in a vacuum state, on the one hand Reduce the influence of dust on the adhesive, on the other hand, redu...

Abstract

The invention relates to a used tire retreading method. The method comprises the following steps: selecting a tire body capable of being retreated; cutting and grinding the surface of the tire body; sewing a crack, and reinforcing the crack by utilizing a liner; smearing adhesive onto the tread under a vacuum state; press-fitting a tread adhesive strip onto the tread of the tire body; finally vulcanizing. The used tire retreading method has beneficial effects that by adopting the retreading method, the waste of resource is greatly reduced, the retreaded tire is good in quality, high in balance quality and low in flat tire rate, the tire body is subject to high temperature and high pressure in the retreading process, factors causing the aging of the tire body can be reduced, the retreading times of the tire body can be increased, and the service life of the tire body can be prolonged.

Description

technical field [0001] The invention relates to a method for retreading old tires. Background technique [0002] With the continuous growth of our country's economy, road vehicles undertake a large number of freight tasks. With the continuous growth of car ownership, the usage and consumption of car tires are also increasing rapidly. The reuse of tire carcass can not only save a lot of rubber and metal resources, but also avoid environmental pollution caused by tire exhaust gas. Pollution has extremely huge economic and social benefits. At present, after automobile tires are generally damaged, except for those that can be repaired, they can only be replaced again. However, the discarding of waste tires has caused a waste of resources on the one hand and polluted the environment on the other hand. Under the existing tire retreading technology, there are fewer and fewer tires that can meet the retreading standard, resulting in a large number of tires being discarded. The tir...
