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 1

[0030] as attached figure 1 Shown, a kind of novel steel wire tire retreading method comprises the steps:

[0031] Step 1. The surface of the carcass 1 is ground, and the dirty tread is removed by grinding the steel wire tire, so that the surface is threaded and rough;

[0032] Step one includes:

[0033] Step 1.1 Grinding the surface of the carcass, grinding the tire crown to a certain size to remove the stained tread.

[0034] Step 1.2 Grinding: Grinding the punctures, punctures and rust on the 2 parts of the ground tire crown to remove the rust.

[0035] Step 2 sizing, brushing the mixture of glue and FRP resin on the tire surface;

[0036] Step 3 Wrap the brand-new rubber-coated steel wire cord fabric 3 on the tire crown, and attach the center rubber;

[0037] Step three includes:

[0038] Step 3.1 Divide: Divide the new rubber-coated steel cord fabric into widths of 1.3cm±0.3cm.

[0039] Step 3.2 Cleaning: Wash the divided new rubber-coated steel wire cord fabric wi...

Embodiment 2

[0047] When the carcass has a lot of punctures, in step 3.3, use rubber-coated steel wire cord fabric 3 to wrap 8 to 10 times in the circumferential direction from 4 cm on both sides of the center line of the carcass to increase the strength of the crown. All the other are the same as embodiment one.

Abstract

The invention relates to a method for retreading and recycling a radial all-steel wire waste tire. The method comprises the following steps: grinding the surface of a tire body, namely grinding the steel wire tire to remove the polluted and damaged tire surface and enable the surface to be a threaded rough surface; gluing, namely brushing a mixture of glue paste and glass steel resin onto the tire surface; winding a brand-new glue steel wire tire fabric onto a tire crown and fitting cushion rubber; after gluing the tire surface, fitting matched tread rubber onto the tire crown wound with the steel wire fabric; vulcanizing in a tank, namely feeding the tire with an enhanced belt layer into a vulcanizing tank for vulcanizing. According to the method, the balance of the tire cannot be destroyed and the operating comfortableness can be improved; the puncture resistance and the burst resistance of the tire crown are improved, a framework of the tire body of the tire is kept non-deformed, and the re-retreading probability of the tire is increased; due to the glue steel wire fabric and the thickness of the cushion rubber, the effect of bonding between the tire body and the tire surface is enhanced, the tear resistance of a pattern block is improved, the chunking situation is reduced, and the bearing and buffering capabilities of the tire are improved.

Description

technical field [0001] The invention relates to a method for retreading and reusing waste tires with radial full steel wires. 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 lar...
