Problems solved by technology

However, existing TPE materials are often used in combination with EVA / PE to foam yoga mats because it is difficult to achieve foaming alone. The foamed yoga mats cannot meet the needs of high-end customers in the market in terms of flexibility, elasticity, and anti-slip properties.

Abstract

The invention discloses a TPE (thermoplastic elastomer) material for a yoga mat and a preparation method of the TPE material. Comprising the following raw materials in parts by weight: 100 parts of a hydrogenated styrene-butadiene-styrene block copolymer, 150 to 300 parts of a styrene-ethylene-butadiene-styrene block copolymer, 100 to 260 parts of white oil, 30 to 60 parts of organic silicone oil, 1 to 3 parts of silicone, 0.1 to 0.5 part of an antioxidant, 0.1 to 0.5 part of a light stabilizer and 1 to 3 parts of a cross-linking agent. The added silicone and styrene-ethylene-butadiene-styrene block copolymer improve the elasticity and hand feeling of the TPE material, so that the flexibility of the processed yoga mat product is improved, and the yoga mat product has good high temperature resistance.

Description

technical field [0001] The invention relates to the technical field of elastomer materials, in particular to a TPE material for yoga mats and a preparation method thereof. Background technique [0002] Yoga mats are often needed in the process of yoga fitness, which is an ideal choice for yoga practitioners. Yoga mats are required to feel soft, non-toxic, tasteless, non-slip, strong resilience, and strong tear resistance. In addition, yoga mats should also effectively block the cold air on the ground, have strong grip, and have outstanding resilience and flatness. , slip resistance, and human skin affinity. Existing yoga mats generally use rubber foam, thermoplastic elastomer (TPE) foam, PVC foam, EVA foam, latex mats, NBR mats, etc. Among them, TPE materials are better in terms of environmental protection, odor, and performance. A trend in the development of yoga mats. However, the existing TPE materials are often used in combination with EVA / PE to foam yoga mats because...
