Problems solved by technology

There are many kinds of repairing methods currently used, and there are two kinds of two-in-one tire repairing methods: one is the patented technology of patent No. 97116515.7, which uses nylon tires with intact sidewalls as the main carcass, and the other The first is the patented technology with the patent number 01114021.6, which uses a full-steel wire radial tire with intact sidewalls as the main carcass, and the products of these two patented technologies use all-steel wires with intact treads and other side damage. Radial tires are used as the main tread for repairing tires, but all-steel wire radial tires with intact treads due to side damage can be directly used for partial repairs, so there is no main tread available in the market, and the available main carcass is lacking. Provide intact main tread but cannot be repaired and utilized, and its repair rate is less than 30%, and the main carcass that cannot be repaired and utilized will cause a vicious cycle of excessive use, making available resources unusable and forming black pollution

Embodiment Construction

[0049] 1. Carry out carcass selection first, and waste carcasses can be divided into four grades: A, B, C and D.

[0050] 1. The tread surface is normally worn to no pattern is a grade A carcass.

[0051] 2. If the tread surface pattern is worn normally and the tread wire is damaged for 1-3 layers, it is a Class B carcass.

[0052] 3. Regardless of the depth of the pattern wear, the carcass that is obliquely blasted at the top of the tire and cracks appear in the transverse skeleton of the steel wire is a Class C carcass (referred to as a single seam carcass).

[0053] 4. Regardless of the depth of pattern wear, the tire with horizontal steel wire blasting is called D-grade carcass.

[0054] 2. Repair

[0055] 1. The repair process of Grade A carcass: see figure 1 a, b, first, the carcass is imitated and polished, and the old skin on the surface is carefully treated until the new oblique steel wire mesh surface 1 is exposed.

[0056] Then place the carcass 2 in the drying ...

Abstract

A method to repair the waste tyre is disclosed the invention. First it divides the waste tyre into the first, second, third and forth degree, then to treat the old skin to expose the oblique steel mesh, next to dry the tyre, then to cover with the adhesives twice, next to lay the cushion glue and main tyre face in the way of the pressure, last to sulphurate. The invention can repair the waste tyre without the main tyre face, it can improve the using ratio of the waste tyre to 90%, and the quality can reach the fist grade of the recovery tyre.

Description

technical field [0001] The invention belongs to a method for repairing waste tires. Background technique [0002] A large amount of old tires are scrapped every year in my country. In order to recycle the scrapped old tires, some manufacturers refurbish and repair them to turn waste into treasure. There are many kinds of repairing methods currently used, and there are two kinds of two-in-one tire repairing methods: one is the patented technology of patent No. 97116515.7, which uses nylon tires with intact sidewalls as the main carcass, and the other The first is the patented technology with the patent number 01114021.6, which uses a full-steel wire radial tire with intact sidewalls as the main carcass, and the products of these two patented technologies use all-steel wires with intact treads and other side damage. Radial tires are used as the main tread for repairing tires, but all-steel wire radial tires with intact treads due to side damage can be directly used for partia...
