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 to make the surface 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 glue on the surface of the tire;

[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 with gasoline.

[0040] Step 3.3 Win...

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 of retreading the old and useless full steel wire tyre by the meridian, comprising the steps as follow: milling the tyre surface, removing the vitiated tyre face and roughening the surface of the steel wire tyre by milling; gluing by coating the plasmagel on surface of the tyre; winding the new glued steel wire curtain cloth on the tread of tyre and adhering with the middle pad glue; adhering the matched type face glue on the tread of tyre, which wound by the glued steel wire curtain cloth, after the tyre face is adhered with glue; then sulphrizing in the tank that is sulphrizing the reinforced tread bracing layer into the sulphrizing tank. The invention will not damage the equilibrium of tyre, improve the controlling amenity, increase the anti-piercing and anti-explosion capability of the tread of tyre, prevent the skeleton of tyre from deforming and improve the retreading rate of tyre. The thickness of glue steel wire curtain cloth installed with the middle pad glue increase the cementation effect between tyre body and the tyre face, improve the anti-tearing capacity of tread block, decrease chunking and improve the bearing and buffer capacity of the tyre.

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...
