Referring to fig. 1 and 4, the present application provides a self-sealing tire repair assembly, which includes a main body portion 1 and a sealant layer 2, the main body portion 1 being configured to contact a self-sealing sealant around a wound 31 of a self-sealing tire 3, the sealant layer 2 being disposed at a side of the main body portion 1 facing the wound 31 of the self-sealing tire 3, and the sealant layer 2 being configured to adhere the main body portion 1 to the self-sealing sealant around the wound 31 of the self-sealing tire 3 to seal the wound 31 of the self-sealing tire 3.

This application is provided with sealant layer 2 on one side of main part 1 through repairing the film at the self sealss tire, directly bond main part 1 on the peripheral self sealss glue layer 2 of wound 31 of self sealss tire 3 through sealant layer 2, thereby accomplish the repair process of self sealss tire 3, compare in when self sealss tire repair film among the prior art repairs self sealss tire 3, need additionally to add the vulcanizing agent and repair the subassembly with self sealss tire 3 and fix on the peripheral self sealss glue of wound 31 of self sealss tire 3, the self sealss tire repair film of this application can be simple, accomplish the repair effect to self sealss tire 3 fast, shorten car owner's latency, the cost of using manpower sparingly and time cost.

Specifically, the self-sealing rubber of the self-sealing tire 3 includes an elastomer, a tackifier, a softener, an antioxidant, a foaming agent, a filler, and a crosslinking agent.

The sealant layer 2 includes thermoplastic elastomer, polyisobutylene, petroleum resin, and terpene resin, and the thermoplastic elastomer includes SEBS and black TPU masterbatch.

In another embodiment, the sealant layer 2 further comprises terpene phenol resin and calcium carbonate, and particularly, the sealant layer 2 is obtained by mixing and stirring SEBS, polyisobutylene, petroleum resin, terpene resin, black TPU master batch, terpene phenol resin and calcium carbonate at normal temperature, extruding the mixture by an extruder, and finally cooling and forming the mixture.

Specifically, under the effect of temperature and pressure, the interdiffusion of molecule can form the interweaving layer between the self sealss of self sealss tire 3 and the sealant layer 2 in this application, thereby make the self sealss tire 3 of this application repair the sealant layer 2 of subassembly closely laminate with the self sealss of self sealss tire 3, and the gas tightness is strong, make self sealss tire 3 repair the subassembly and be difficult for coming off from self sealss tire 3, avoid appearing the secondary gas leakage phenomenon, the repair firmness between self sealss tire 3 repair subassembly and the self sealss tire 3 has been improved, thereby the life of self sealss tire 3 after repairing has been prolonged, the safety of traveling of self sealss tire 3 has been improved.

Specifically, the material of the main body 1 is the same as that of the self-sealing tire 3. So set up, can guarantee that each item performance of repairing back self sealss tire 3 does not receive the influence of material change. In the present example, the main body 1 and the self-sealing tire 3 are made of rubber.

Referring to fig. 2, the main body 1 has a shape thick in the middle and thin in the two sides. Because the outer surface of the self-sealing tire 3 has a certain radian, the main body part 1 is set to be thick in the middle and thin on two sides, so that the main body part 1 is favorably attached to the outer surface of the periphery of the wound 31 of the self-sealing tire 3.

Referring to fig. 2, the main body portion 1 includes a top surface 11 and a bottom surface 12 connected, the top surface 11 is for contacting a self-sealing adhesive around a wound 31 of the self-sealing tire 3, and the sealant layer 2 is disposed on the top surface 11.

With reference to fig. 1 and 4, the body portion 1 is sized to match the size of the cut 31 of the self-sealing tyre 3. By selecting the body 1 having an appropriate size according to the size of the cut 31 of the self-sealing tire 3, the repair of the cut 31 of the self-sealing tire 3 can be economically accomplished, and the waste of materials can be avoided.

In particular, the width of the cut 31 of the self-sealing tyre 3 of the present application is between 0.1 and 0.5 mm.

In the present embodiment, the diameter of the body 1 is not less than 3 cm and not more than 6 cm.

Specifically, the diameter of the main body portion 1 is too small, the contact area of the main body portion 1 with the self-sealing tire 3 is small, the main body portion 1 is easily detached from the self-sealing tire 3, and the repair effect of the main body portion 1 having a too small diameter on the self-sealing tire 3 is also not good. The diameter of the main body part 1 is too large, which wastes materials and destroys the dynamic balance of the self-sealing tyre 3, and has potential safety hazard.

Referring to fig. 2, the thickness of the body portion 1 is 3 mm or more and 4 mm or less. Specifically, for ordinary film, the thickness of main part 1 of this application is thinner, can avoid thickness too high, leads to the dead weight of main part 1 too heavy, influences the appearance of this condition of dynamic balance of self-sealing tire 3.

Referring to fig. 1, the size of the sealant layer 2 matches the size of the main body portion 1.

Specifically, the sealant layer 2 covers the side of the main body 1 facing the cut 31 of the self-sealing tire 3, and the side of the main body 1 facing the cut 31 of the self-sealing tire 3 can be completely adhered to the sealant around the cut 31 of the self-sealing tire 3, thereby improving adhesion between the main body 1 and the self-sealing tire 3.

Referring to fig. 1 and 3, self sealss tire repair film still includes protective layer 4, and protective layer 4 detachably sets up on sealant layer 2, so sets up, can avoid impurity to get into sealant layer 2, destroys sealant layer 2's viscidity, improves sealant layer 2 and self sealss tire 3's bonding fastness.

Referring to fig. 1 and 3, the size of the protective layer 4 is greater than or equal to the size of the sealant layer 2. With this arrangement, the protective effect of the protective layer 44 on the sealant layer 23 can be improved.

Referring to fig. 1 and 3, the protective layer 4 has no tackiness so that the protective layer 4 is peeled off from the sealant layer 2.

In this embodiment, the protective layer 4 can be silicone oil paper, which can prevent the protective layer 4 from adhering to the sealant layer 2 and protect the sealant layer 2 from being contaminated by impurities.

The above is only the preferred embodiment of the present invention, not limiting the scope of the present invention, all of which are under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
