Abstract
The invention discloses a precured tread and retreaded tire using the precured tread. The precured tread comprises transverse pattern grooves and longitudinal pattern grooves; and the difference from the prior art is that: vent holes are formed on the transverse pattern grooves. Compared with the prior art, the precured tread and the retreaded tire using the precured tread have the advantages that: due to the adoption of the precured tread, during retreading and laminating a tire, the gas is exhausted from the vent holes on the transverse pattern grooves or the longitudinal pattern grooves; the air leakage phenomenon generated in the laminating process can be effectively reduced even avoided; and the gas in the pattern grooves is more easily exhausted during curing the retreaded tire, the middle pad glue can be embedded in the vent holes on the precured tread, and the aim of improving the adhesive strength between the precured tread of the retreaded tire and the middle pad glue is fulfilled. The precured tread and the retreaded tire using the precured tread have low cost, can solve the air leakage problem generated in the laminating process in the prior art by only forming the vent holes on the precured tread. Therefore, the phenomena of retread bulge and separation and fragile adhesion of the retreaded tire are avoided.
Description
Technical field
The present invention relates to a kind of precured tread, the invention still further relates to and use rebuilding a tyre of this precured tread.
Background technology
Rebuild a tyre and be widely known by the people as new-treaded tire.Generally form in the following manner in the prior art and rebuild a tyre: thus basic tire formed from removing tyre surface or tyre surface and a part of bracing ply with the tire of crossing, will paste basic tire again by the tyre surface that new material is made then.As the manufacture method that rebuilds a tyre, proposed to make basic tire and the green tread rubber sulfureted method in mould (envelope) then that is engaged with each other, and in flat plate mold prevulcanization tread-rubber and form figuratum one-tenth precured tread, and paste basic tire method by the precured tread that will so form with lower temperature and the sulfuration of the low pressure on the stickup face.
In the method for the above-mentioned precured tread of formation earlier, exist following deficiency: at first, be difficulet and sulky easily during applying, gas is difficult to get rid of during sulfuration, easily causes finished product to come to nothing; Once more, the suffered low pressure of groove will be significantly smaller than other position in the time of sulfuration, and residue gas during applying is known from experience to groove and overstock, and causes the groove sky, is prone to tyre surface after the sulfuration and heaves, comes to nothing and bonding problem such as not firm.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of with low cost, when rebuilding a tyre, can effectively get rid of the gas between tyre surface and the basic tire, thereby avoid the tyre surface bulge occurring, come to nothing and the precured tread of bonding not firm phenomenon and use rebuilding a tyre of this precured tread.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of precured tread comprises cross groove and circumferential pattern ditch, unlike the prior art be: on cross groove, offer deflation hole.
The number of deflation hole can be done concrete definite according to the tire size, offers 2～3 deflation holes on general every cross groove, and described deflation hole is uniform along the bearing of trend of cross groove.
The diameter of described deflation hole is advisable with 1～5mm.
Residual gas when fitting in order better to discharge can also offer deflation hole on the circumferential pattern ditch.
The offering spacing and can determine according to tire size of described circumferential pattern ditch upper air-vent generally is that the spacing between two deflation holes is 10～20cm on every circumferential pattern ditch.
The diameter of described circumferential pattern ditch upper air-vent is advisable with 1～5mm equally.
The present invention also provides a kind of above-mentioned precured tread rebuilding a tyre as tyre surface of using.
Compared with prior art, the invention has the advantages that:
1, adopt precured tread of the present invention, tire can make gas discharge from the deflation hole on horizontal or the circumferential pattern ditch when renovation is fitted, effectively the difficult and sulky phenomenon that reduces even can avoid prior art to produce in the applying process;
2, rebuild a tyre and the time make the easier discharge of gas of groove portion in sulfuration, simultaneously in pad glue can be embedded in the deflation hole on the precured tread, reach the purpose that improves prevulcanization retreading tire protector and middle pad glue bond intensity;
3, the present invention is with low cost, only need that deflation hole is set and to solve the difficult and sulky phenomenon that in the applying process, produces in the prior art on precured tread, thereby avoid occurring the phenomenon that rebuilds a tyre the tyre surface bulge, come to nothing, improve the existing bonding not firm situation that rebuilds a tyre.
Description of drawings
Fig. 1 is the planar structure scheme drawing of one embodiment of the present invention.
Number in the figure is:
1, cross groove; 2, deflation hole; 3, circumferential pattern ditch.
