Description

Technical Field

[0001] The invention relates to the technical field of tennis shoes, in particular to a lightweight and non-slip tennis shoe and a method for manufacturing the sole thereof. Background Art

[0002] Tennis is a very intense sport. Tennis players need to constantly adjust their hitting positions according to the landing point of the tennis ball, so they need to do rapid running, acceleration, turning, sudden stop, jump and other intense foot movements on the tennis court. Therefore, the comfort of tennis shoes is very important, especially the elasticity and softness of the soles of tennis shoes. Otherwise, with such a large amount of physical energy consumption, wearing a pair of tennis shoes with poor bounce will not be conducive to the players' competition, and will also cause great harm to the players' feet.

[0003] The existing tennis shoes have ordinary functions and the elasticity of the soles is not very ideal. However, the most significant feature of tennis compared to other sports is that it requires accurate judgment of balls coming from different directions and moving steps accordingly, which requires higher elasticity of the soles. At the same time, if the grip of the soles is not good during the running or jumping process, it may cause ankle sprains. Therefore, a lightweight and non-slip tennis shoe and a method for manufacturing the soles thereof are needed to solve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a lightweight and non-slip tennis shoe and a method for manufacturing the sole thereof, mainly to solve the problem that the existing tennis shoes have ordinary functions and the elasticity of the sole is not very ideal. However, the most significant feature of tennis compared to other sports is that it requires accurate judgment of balls coming from different directions and moving steps accordingly, which requires higher elasticity of the sole. At the same time, if the sole has poor grip when athletes are running or jumping, ankle sprains may occur.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A lightweight and non-slip tennis shoe comprises an upper and a sole, wherein the upper is fixedly connected to the top of the sole, a mounting groove is provided in the sole, an elastic plate is fixedly connected in the mounting groove, a plurality of suction cup-shaped grooves are provided at the bottom of the sole at the forefoot and the rear heel, a plurality of non-slip protrusions are integrally formed at the bottom of the sole, and the non-slip protrusions are located between the forefoot and the rear heel.

[0006] Furthermore, two first air-permeable nets and two second air-permeable nets are sewn on the upper surface of the upper, and the two first air-permeable nets and the two second air-permeable nets are symmetrically distributed.

[0007] On the basis of the foregoing solution, a reinforcing band is sewn on the upper surface of the shoe upper, and a rear strap is sewn at a position on one side of the shoe upper near the rear heel.

[0008] The present invention also provides a method for manufacturing a sole of a lightweight and anti-slip tennis shoe, comprising the following steps: S1: Prepare materials, including 10-15 parts of rubber, 5-8 parts of foaming aid, 3-6 parts of plasticizer, 4-7 parts of softening agent, 3-6 parts of stearic acid, 4-7 parts of filler, 4-8 parts of pigment, 2-5 parts of accelerator, 2-8 parts of silica, and 4-6 parts of modified ultrafine kaolin; S2: Prepare a mold. According to the specific shape of the sole, fabricate the corresponding sole mold by milling, and clean and dry the mold for later use; S3: High-pressure reaction. Add stearic acid, modified ultrafine kaolin, silica, softening agent, and filler into a high-pressure reactor, and react at 50-80°C for 3-4 hours; cool to room temperature to obtain a prepolymer; S4: Mixing in a Banbury mixer. Add the rubber body and the prepolymer in S3 into the Banbury mixer, mix at 80-90°C for 15-20 minutes, granulate after open milling to obtain a formed masterbatch; S5: Mixing in an open mill. Put the formed masterbatch on the open mill, cut with a cutter twice, then add pigment and accelerator for mixing. After the material is eaten, cut with the left and right cutters 4-8 times, thin-pass and make triangular packages 4-5 times, exhaust, and take off the sheet to obtain a mixed rubber; S6: Vulcanization. Put the mixed rubber into the pressing mold of the vulcanizer, and vulcanize at 9-11 MPa and 140-160°C to obtain the sole material; S7: Sole making. First, coat the sole mold with a mold release agent, dry it, then inject the sole material into the sole mold, keep it warm for 10-12 minutes, and demold to obtain a sole blank; S8: Embedding. Process the elastic plate into the corresponding shape according to the sole, then coat the surface of the elastic plate with glue, and then embed the elastic plate into the reserved installation groove of the sole and bond it with glue to obtain the sole.

[0009] As a further solution of the present invention, the rubber is composed of natural rubber, styrene-butadiene rubber, and cis-butadiene rubber, and the weight ratio of natural rubber, styrene-butadiene rubber, and cis-butadiene rubber is: (4-6):(1.5-2.5):(2-4).
