Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tire production, in particular to a novel all-steel tire crown structure. Background Art
[0002] With the development of vehicle performance and modern roads, higher requirements are placed on tire performance. The key points of tire performance are mainly profile design, component design and frame selection. In component design, especially the crown, a reasonable crown design can improve the crown performance of the tire and play a role in high-efficiency transportation operations.
[0003] The existing crown structure, especially for the crown with a thickness greater than 25mm, has the problem of too thin thickness of the low-heat-generating rubber in the middle. When the tire is under harsh conditions such as fast speed or large load, the heat is not easy to dissipate, which is prone to quality problems and reduces the service life of the tire.
[0004] Based on this, a novel all-steel tire crown structure is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content
[0005] The utility model aims to provide a novel all-steel tire crown structure to solve the problem that the low heat generation rubber in the middle of the existing crown structure is too thin, and the heat is not easy to dissipate under harsh conditions such as fast or heavy load, thereby reducing the service life of the tire.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A novel all-steel tire crown structure comprises an upper wear-resistant colloid, a lower low heat buildup colloid, and an adhesive film. The upper wear-resistant colloid is bonded to the lower low heat buildup colloid, the lower low heat buildup colloid is bonded to the adhesive film, and staggered convex and concave bonding surfaces are provided at the bonding point between the upper wear-resistant colloid and the lower low heat buildup colloid.
[0008] On the basis of the above technical solutions, the present invention also provides the following optional technical solutions:
[0009] In an optional solution, the diameter a between the lower layer of low heat generation colloid and the combined convex surface is greater than twice the diameter b between the lower layer of low heat generation colloid and the combined concave surface.
[0010] In an optional solution: the upper layer of wear-resistant colloid is extruded through an upper extruder of the composite equipment.
[0011] In an optional solution, the lower layer low heat generation colloid is extruded through a lower layer extruder of a compounding device.
[0012] In an optional solution: the upper wear-resistant colloid is made of natural rubber, nitrile rubber, butadiene rubber, phenolic resin, nano carbon black, nano silicon dioxide, nano clay, and p-phenylenediamine.
[0013] In an optional solution: the lower layer of low heat generation colloid is made of mesoporous silica and tin tetrachloride.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0015] The utility model changes the shape of the pre-mouth shape on the tread crown pre-mouth shape, depending on the tread thickness and pattern style, the convex and concave are alternately formed. When the tread crown is pressed out, the upper wear-resistant colloid extruded by the upper extruder of the composite equipment and the low heat generation colloid extruded by the lower extruder of the composite equipment pass through the novel pre-mouth shape structure to form a combined convex surface and a combined concave surface in an alternating pattern. After compounding the two in the machine, the contact surface of the two forms a tread form with alternating thickness of the lower low heat generation colloid and the upper wear-resistant colloid, thereby overcoming the shortcomings of the prior art and improving the heat dissipation performance of the tire.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] In one embodiment, Figure 1-Figure 3 As shown, a novel all-steel tire crown structure includes an upper wear-resistant colloid 1, a lower low heat generation colloid 2, and an adhesive film 4. The upper wear-resistant colloid 1 is bonded to the lower low heat generation colloid 2, and the lower low heat generation colloid 2 is bonded to the adhesive film 4. The bonding place between the upper wear-resistant colloid 1 and the lower low heat generation colloid 2 is provided with staggered bonding convex surfaces 31 and bonding concave surfaces 32. The tread form of alternating thickness of the lower low heat generation colloid 2 and the upper wear-resistant colloid 1 overcomes the shortcomings of the prior art and improves the heat dissipation performance of the tire.
[0022] In one embodiment, Figure 2As shown, the diameter a between the lower layer of low heat build-up colloid 2 and the combined convex surface 31 is larger than twice the diameter b between the lower layer of low heat build-up colloid 2 and the combined concave surface 32 .
[0023] In one embodiment, Figure 2 and Figure 3 As shown, the upper layer of wear-resistant colloid 1 is extruded through the upper extruder of the composite equipment.
[0024] In one embodiment, Figure 1 As shown, the lower layer low heat build-up colloid 2 is extruded through the lower layer extruder of the compounding equipment.
[0025] In one embodiment, Figure 1 As shown, the upper wear-resistant colloid 1 is made of natural rubber, nitrile rubber, butadiene rubber, phenolic resin, nano carbon black, nano silicon dioxide, nano clay, and p-phenylenediamine. P-phenylenediamine can effectively improve the anti-aging performance of the tire, and nano carbon black, nano silicon dioxide, and nano clay can effectively improve the strength of the tire.
[0026] In one embodiment, Figure 2 and Figure 3 As shown, the lower layer of low heat generation colloid 2 is made of mesoporous silica and tin tetrachloride. During the modification process of mesoporous silica, γ-mercaptopropyltrimethoxysilane is introduced into the pores on the surface of mesoporous silica by ultrasonic vibration and static diffusion, and grafted into the pores of mesoporous silica. The natural rubber molecules entering the pores of mesoporous silica react with the mercapto groups on the γ-mercaptopropyltrimethoxysilane molecules, so that the natural rubber and mesoporous silica are connected by chemical bonds, which increases the binding force between the mesoporous silica and the natural rubber molecular chains, thereby reducing the heat generation inside the rubber material.
[0027] The above embodiment discloses a novel all-steel tire crown structure, which changes the pre-mouth shape on the crown pre-mouth shape, and depending on the tread thickness and pattern style, alternately forms convex and concave. When the crown is pressed out, the upper wear-resistant colloid 1 extruded by the upper extruder of the composite equipment and the low heat generation colloid extruded by the lower extruder of the composite equipment pass through the novel pre-mouth structure to form an alternating pattern of combined convex surface 31 and combined concave surface 32. After compounding in the machine, the contact surface of the two forms a tread form with alternating thickness of the lower low heat generation colloid 2 and the upper wear-resistant colloid 1, thereby overcoming the shortcomings of the prior art and improving the heat dissipation performance of the tire.
[0028] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
