Abstract
Steel wire from waste radial tyre wrong fount Rebuilding engineering retreads technique.Accident, the service lifes such as single tire pressure is quick-fried, it is quick-fried to hit, thorn is quick-fried often occur at work for engineering retreads shorter at present.The steel wire from waste radial tyre wrong fount Rebuilding engineering retreads technique of the present invention, steel wire floor is isolated from waste and old sub steel wire radial tire, and its copper coating processing is formed to the metal-cord of reinforcement；Selection carcass cleans and carries out local damage repairing and reinforcement；Waste steel wire casing ply between old body piles and the glue-line that recaps after treatment after one layer of processing of reinforcement, is vulcanized using vulcanizers with segmented mold, so far forms steel wire from waste radial tyre wrong fount Rebuilding engineering retreads afterwards.The inventive method into wrong fount Rebuilding engineering retreads service life be 1.2 times of common retreads, remained basically stable with the service life of the new tire of same model, and renovate totle drilling cost is only new tyre totle drilling cost 40%.
Description
Technical field：
The present invention relates to a kind of steel wire from waste radial tyre wrong fount Rebuilding engineering retreads technique.
Background technology：
Engineering tyre is used for opencut and earth work etc., wherein opencut can be described as engineering tyre using most concentrate,
The most harsh place of use condition, it is desirable to which engineering tyre has the characteristics that anti-puncture, cut resistant, wear-resistant, heat is low.General feelings
Under condition, an engineering automobiles or engineering machinery every year must re-type 5~6 times, a new engineering tyre price it is thousands of very
To tens of thousands of yuans, therefore, effectively extend tyre life or reduction tire cost has a direct impact to the economy of engineering truck.
Tyre rebuilding can maximally utilise the use value of tire, at present turn into it is internationally recognized saving robber materialses,
Solve junked tire black pollution, valuable resource regeneration mode.Therefore, how engineering retreads pair effectively to be used
There is very actual meaning in engineering automobiles user or an enterprise.However, China's engineering tyre renovation enterprise renovates out
Engineering tyre quality it is uneven, engineering retreads often occur that single tire pressure is quick-fried, it is quick-fried to hit, the thorn accident such as quick-fried at work,
Service life is shorter, and frequent re-type causes transport enterprise's engineering retreads expenses increase.
The content of the invention：
The purpose of the present invention is that steel wire from waste radial tyre cord is associated with engineering tyre renovation, carries out waste and old meridian
Bead wire wrong fount Rebuilding engineering retreads production technology and reinforcement study mechanism, realize the benefit of engineering retreads carcass
Strong and local damage reparation, and part engineering tyre carcass cord cords break layer regeneration can be made, solve carcass steel
The engineering tyre that silk cord sustains damage can realize the problem of renovation recycles and is unlikely to directly to scrap, while in order to solve
The problem of recycling of steel wire from waste radial tyre, and a kind of steel wire from waste radial tyre wrong fount Rebuilding engineering is provided and turned over
New tire technique.
Above-mentioned purpose is realized by following technical scheme：
A kind of steel wire from waste radial tyre wrong fount Rebuilding engineering retreads technique, described retreads technique include useless
Old metal-cord processing procedure, old body piles repairing treatment process and old body piles after treatment and the glue-line that recaps
Between waste steel wire casing ply after one layer of reinforcement processing process；Wherein,
Waste steel wire casing ply processing procedure includes：First, waste and old radial wire cord tire is selected, afterwards from waste and old sub steel
Steel wire floor is isolated in silk radial tire, waste steel wire casing ply is made using the steel wire floor isolated afterwards, is given up afterwards
Old metal-cord copper coating processing, so far form the metal-cord of reinforcement；
Old body piles repairing treatment process includes：First, carcass is selected, carcass is cleaned afterwards and carries out the detection of local damage,
Afterwards to being repaired at the local damage that detects and reinforcement, polish carcass and applies carcass primer afterwards, pastes afterwards slow
Glue is rushed, treats to crimp with the metal-cord of reinforcement；
The process of waste steel wire casing ply between old body piles and the glue-line that recaps after treatment after one layer of processing of reinforcement
Including：The one side of the metal-cord of reinforcement and buffering adhesive are pressed, glued again in the another side of the metal-cord of reinforcement afterwards
One layer of buffering adhesive is pasted, the wirecord fabric of reinforcement is placed on afterwards between the old body piles after recap glue-line and processing and glued
Close, vulcanized afterwards using vulcanizers with segmented mold, so far form the renovation of steel wire from waste radial tyre wrong fount Rebuilding engineering
Tire.
Beneficial effect：
The present invention uses steel wire from waste radial tyre wrong fount Rebuilding engineering retreads production technology and reinforcement study mechanism,
The reinforcement of engineering retreads carcass and the reparation of local damage are realized, and part engineering tyre carcass cord cord can be made
Zone of fracture regenerates, and the engineering tyre that carcass cord cord sustains damage can realize that renovation recycles and is unlikely to directly to scrap,
Solves the problems, such as the recycling of steel wire from waste radial tyre simultaneously, it may be said that be to kill two birds with one stone, can not only solve environmental protection
Problem, and the new way that waste radial tire utilizes is opened up, the utilization rate of old tire can be made to bring up to more than 20% from 10%,
Turn waste into wealth, and can effectively solve the problem that engineering retreads carcass cord cord impaired and the skill that renovation uses can not be carried out again
Art problem.Using the steel wire from waste radial tyre wrong fount Rebuilding engineering retreads production technology and reinforcement mechanism, use
Mould vulcanization method has carried out renovation production to 26.5R25 old tires, and institute's innovation tire detects through physical and mechanical properties, its index
Meet engineering machinery retreads HG/T3979-2007 professional standards.Finished product carries out the anti-quick-fried test of thorn in Open pit Area, and its thorn is quick-fried
Rate drops to the 20% of wrong fount Rebuilding engineering retreads by the 40% of ordinary skill retreads, meanwhile, field feedback
Also indicate that, 26.5R25 engineering retreads bearing capacity that waste and old meridian steel wire wrong fount remanufactures, anti-puncture, the anti-quick-fried energy of thorn
Power greatly improves, and general performance is good, and its service life is 12 months or so, and the ordinary skill retreads with model use
Life-span is 10 months or so, and the service life with model newly built construction tire is generally 12 months or so, and wrong fount Rebuilding engineering turns over
New Life of Tyre is 1.2 times of common retreads, is remained basically stable with the service life of the new tire of same model, and totle drilling cost
Only the 40% of new tyre totle drilling cost, the use for engineering retreads will produce great pushing effect.
