Embodiment 1

[0039] 1. A tire retreading process, comprising the following steps:

[0040] Step 1: Clean the stains on the inside and outside of the tire to be retreaded with clean water, polish the surface of the tire to be retreaded, and smooth the pattern on the tire surface; when grinding the surface of the tire to be retreaded, match the carcass damage part ;

[0041] Step 2: Evenly coat the polished tire surface with polyurethane adhesive;

[0042] Step 3: Evenly paste the liner on the surface of the tire coated with polyurethane adhesive, blow off the dust on the surface of the liner with an air duct; dry the clean tire at a temperature of 50°C; Apply adhesive glue evenly on the top;

[0043] Step 4: Carry out pre-vulcanization treatment on the retreaded tread with pattern, and stick the tread with pattern after pre-vulcanization treatment on the pad;

[0044] Step 5: Put a PE plastic film on the surface of the tire pasted with the patterned tread, and the PE plastic film is even...

Abstract

The invention relates to the field of tire production, in particular to a tire retreading process. The process comprises the following steps: 1, polishing the surface of a tire, and rubbing down patterns; 2, uniformly coating the surface of the tire with adhesive; 3, uniformly attaching a liner onto the surface of the tire, and uniformly coating the liner with the adhesive; 4, attaching a tread with patterns, which is subjected to prevulcanization, onto the liner; 5, covering the surface of the tire with a PE plastic film, wherein the PE plastic film is attached onto the surface of the tire; 6, assembling the tire covered with the PE plastic film, and mounting an inner tube, a pressure ring and a wheel rim on the inner side of the tire, thereby pressing the lateral side of the PE plastic film into the wheel rim to completely encapsulate the tire by the PE plastic film; 7, carrying out secondary vulcanization on the tire to manufacture a retreaded tire. According to the invention, the PE plastic film, instead of an encapsulating cover, is used for encapsulating the tire, so that the cost of the tire retreading process is lowered while ensuring the encapsulation effect.

Description

technical field [0001] The invention relates to the field of tire production, in particular to a tire retreading process. Background technique [0002] With the development of science and technology and the advent of a new generation of tires, people's requirements for retreaded tires have increased. A new type of tire retreading technology called "pre-vulcanized retreading" has been widely used at home and abroad. The "pre-vulcanization retreading" technology is to glue the pre-vulcanized pattern tire tread on the ground tire carcass. [0003] The Chinese patent with the publication number CN104044291 discloses a tire retreading process, which adopts the tire retreading technology of "pre-vulcanized retreading". , Pressure ring and rim, carry out secondary vulcanization, so that the carcass and the pre-vulcanized tread can be firmly combined. [0004] The envelope is a fixed accessory for the secondary vulcanization of the tread in the process of pre-vulcanization and ret...
