Embodiment Construction

[0018] This specific embodiment adopts the following technical scheme: the technological process is: tire grinding-repairing-dust removal-drying-spraying mortar-adding steel wire inside or outside the carcass-gluing-retreading vulcanization.

[0019] The tire grinding is to remove the oxidized layer on the old surface of the rubber factory, and make the retreaded tire have a fixed cross-sectional shape and peripheral size, and grind out a fresh and clean surface, so that it has good chemical activity and improves the adhesion between the grinding surface and the vulcanized rubber. combined ability.

[0020] The said repairing is that after the tire is ground, there will be surface thread damage on the ground surface, which will affect the bonding strength, therefore, these surface phenomena should be piled up and repaired.

[0021] The dust removal is to remove dust from the surface after grinding the retreaded tire, so as to keep the grinding surface clean.

[0022] Said dry...

Abstract

The invention provides a new nylon tire and wire cloth combined retreading engineering tire production process, and relates to the technical field of vehicle tire improvement. The process comprises: grinding a tire, trimming, removing dust, drying, carrying out spray coating of a mucilage, adding steel wires to the inner surface or the outer surface of the tire, adhering a glue, and carrying out retreading sulfurization, wherein the retreading sulfurization process comprises: 1, adopting a complete-automatic segmental mold sulfurization machine, wherein the sulfurization temperature is 140-150 DEG C; 2, adopting steam, wherein the sulfurization temperature is 140-150 DEG C; and 3, obtaining the inner pressure during sulfurization, wherein the tire inner pressure is 1.2 mpa. According to the present invention, tire burst can be reduced, the prices is low, practicality is strong, energy sources can be saved, and the characteristics of environmental protection is provided.

Description

Technical field: [0001] The invention relates to the technical field of automobile tire improvement, in particular to a manufacturing process of a two-in-one retreading engineering tire of a wire tire and a steel wire tire. Background technique: [0002] my country is a big consumer of rubber resources. As of 2009, the output of waste tires has exceeded 230 million. If the technology is strong, the wear-resisting life of retreaded tires can reach 120% to 130% of new tires of the same specification. The energy consumption and materials of retreaded tires Only a quarter of a new tire. Judging from the background and trend of industry development, the used tire retreading industry still has huge development potential and market prospects, and the sustainable development of the used tire retreading industry should be accelerated. [0003] Among the hundreds of rubber products, the rubber required for the production of tires in my country accounts for about 70% of the total rubbe...
