Abstract
The invention provides a renovating preparation method for installing all-steel cord at an engineering tire. The renovating preparation method is characterized by taking a tire body of an original diagonal tire which can be continuously utilized as a part used for installing an all-steel cord layer, and comprise the following steps: polishing a bonding surface part to generate a slightly concave-convex surface which is easy to stick at the part needing to be renovated and bonded; coating the concave-convex surface with tread primer; naturally drying for 20 minutes in the environment with the temperature of 20-30 DEG C; performing end-to-end butt joint on the two angles alpha and alpha 1 of the all-steel cord layer to form the ring-shaped all-steel cord layer by matching; and connecting in a vulcanized way to form the product, wherein the all-steel cord layer is configured with the top surface of an outer tire. The renovating preparation method is simple to operate and low in processing cost, and is capable of recycling waste and saving energy; the utilization rate of an old tire is increased to 70% from 30%; the service life of the tire is more than 90% of that of a new tire; the energy consumption is lowered by 40%; the material used by the renovating preparation method is only 10-20% of that used by the new tire. The price of the retreaded tire used by a user is more than 70% lower than that of the new tire.
