Embodiment 1

[0051] According to the dosage of the formula in Table 1, the cis-butadiene rubber and the solution-polymerized styrene-butadiene rubber are weighed as the first group, the silica is weighed as the second group, and the remaining materials are weighed as the third group.

[0052] Pour the first group of rubber raw materials into the internal mixer, start the internal mixer, and mix for 8 minutes. When the temperature of the internal mixer rises to 100 °C, mix for 2-3 minutes, and pour the white carbon black into the internal mixer. , Mixing for 8 minutes, when the temperature of the internal mixer rises to 130 ° C, pour the third group of ingredients and mix for 15 minutes, and finally pour out the mixed rubber.

[0053] Pour the mixed rubber into the mill, and roll it continuously for 5-8 times to form a 2mm thick sheet.

[0054] The rubber sheets of the outer layer, the middle layer and the inner layer are respectively produced according to the above steps.

[0055] Cut the...

Abstract

The invention relates to the technical field of footwear products, and provides a photochromic multifunctional rubber outsole and a preparation method thereof.The photochromic multifunctional rubber outsole is prepared from an outer layer rubber sheet, a middle layer rubber sheet and an inner layer rubber sheet which are sequentially stacked through one-time mold pressing vulcanization forming with the portion away from the foot as the outside, the outer layer rubber sheet is made of a transparent rubber material with the hardness being 65-70 A, and the middle layer rubber sheet is made of a transparent rubber material with the hardness being 65-70 A; the inner-layer rubber sheet is made of a transparent rubber material with the hardness of 55-60A, and the middle-layer rubber sheet is made of a photochromic rubber material with the hardness of 60-65A; the outer-layer rubber sheet, the middle-layer rubber sheet and the inner-layer rubber sheet are prepared from butadiene rubber, butadiene styrene rubber, white carbon black, a cross-linking agent and a coupling agent; and the preparation material of the middle-layer film comprises a photosensitive material. The rubber outsole provided by the invention not only has excellent wearing comfort, but also has high hardness, high wear resistance, skid resistance and the like which meet the requirement of high mechanical properties, can change color along with illumination, and is beneficial to improving the aesthetic property of shoes.

Description

technical field [0001] The invention relates to the technical field of footwear products, in particular to a photochromic multifunctional rubber outsole and a preparation method thereof. Background technique [0002] As consumers have higher and higher functional requirements for footwear products, not only a pair of rubber soles are required to meet basic mechanical properties, but also high elasticity and soft comfort are required. Among them, the outsole (also known as the outsole) of the shoe that is in direct contact with the ground is usually the outsole (also called the outsole), which bears the full weight of the human body during running, jumping and walking, and is subject to frequent bending and wear, so it needs to have Higher wear resistance, slip resistance and mechanical properties; while the sole-like structure close to the foot needs to have better soft comfort. However, due to the limitation of material properties, materials with high mechanical properties...
